2. E501-A Waterous Pump And Diesel Vanguard Engine:
The E501-A is a Waterous “Motor Pump” combination. It is a three-
cylinder, 952 cc diesel-driven pump capable of exceeding NWCG Type
5 standards: Minimum 50 GPM at 100 psi. The E501-A is unique to its
similar (same generation) apparatus in that it is a diesel-driven pump.
(Apparatus No. 55, Apparatus No. 63, and Apparatus No. 64 all have
gasoline auxiliary pump engines.)
Both brush auxiliary pumps (Apparatus Nos. 62 and 55) get their fuel
supply from the apparatus main fuel tanks. Patrol auxiliary pumps
(Apparatus Nos. 63 and 64) each have their own fuel tank mounted
adjacent to the pump engine.
a. Valves:
i. Suction: There are two valves on the suction side of the
pump. One valve is located between tank and the intake
side of the pump and is left in the open position, except
when drafting or receiving water from a hydrant or other
source. The second suction valve is normally in the closed
position and is used for an external water source.
ii. Discharges: There are four (4) discharges: two (2) reel
lines and two (2) 1-1/2-inch (hose tray and rear of the
apparatus, which has a gated wye.)
a) Hose Tray: This valve controls the flow to the hose
tray. DO NOT OPEN THIS VALVE UNTIL ALL
HOSE IS REMOVED FROM TRAY.
Effective Date: April 2014 Mariano Caro, Equipment Supervisor
Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 6 of 22
b) Reel: This valve controls the flow to the hose reel
and is normally left in the open position.
iii. Tank Fill: This valve controls the flow of water from the
pump discharge to the water tank. When this valve is
opened, pressure may fall below 30 psi and the Low
Pressure Shut-Off may activate.
iv. Hydrant Fill: This valve controls the water to the optional
hydrant fill. This valve flows directly into the tank.
b. Fire Pump Operations:
In order to prevent running the pump without water, Apparatus 62
is equipped with an automatic shut-off system. When the system
is activated, the pump wills shutoff whenever the pump discharge
pressure falls below 30 psi. In order to start the engine, the
automatic shut-off switch must be in the Start position (See
Figure 4); Apparatus 62 is equipped with a momentary switch that
will automatically return to the run position when released. This
momentary switch disengages the Low Pressure Shut-off system
until the switch is released, once released the Low Pressure
Shut-off is engaged. If the pump is not throttled up high enough
and a discharge is opened, the pump pressure may drop low
enough to activate the Low Pressure Shut-off. If the pump runs
out of water, or the pressure drops below 30 psi, the pump
will automatically shut off.

c. Priming the Pump:
The primer valve is located on the control panel. (See Figures 5
and 6.) The primer valve allows the primer to be opened when
priming and closed at all other times. The primer pump is a 12-
volt electrically driven pump. The pump is activated by a
momentary push button located on the control panel.
i. Do not start the engine until prime is established.
ii. Close all valves on the discharge side of the pump
including discharge, reel, by-pass, and tank fill.
iii. Open the priming valve.
iv. Activate the priming pump until a full flow of water is
achieved through primer overflow tube. This will be visible
from the bottom of the apparatus below the pump panel.
v. Close the primer valve.

d. Starting the Engine:
a. Hold the automatic shut-off in the START position.
b. Turn the ignition to the run position and wait until the yellow
glow-plug indicator lamp turns off (approximately 10 seconds).
c. Turn the ignition to the START position and hold until the engine
starts.
d. Slowly increase the engine throttle to build pressure.
e. Check the pressure reading on the gauge to verify the pump is
primed.
f. Partially open the discharge valve, checking the gauge to verify
pressure is maintained. If the pressure drops, maintain engine
speed and repeat the priming procedure until the pressure is
restored.
g. SLOWLY open the discharge valve or nozzle.
h. With the discharge open, advance the throttle to adjust the
speed of the engine until the required water discharge pressure
is achieved.
i. Release the temporary automatic shut-off down switch to the
RUN position.
j. Open the TANK FILL VALVE slightly to ensure the pump stays
cool.
e. Engine Fails to Start or Run:

Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 9 of 22
i. Check the position of the automatic shut-off switch.
ii. Make sure the engine switch is in the RUN position and the pilot
light is on.
iii. Check that the spark plug is operating and set at the correct
gap. (Refer to the engine manufacturer’s manual.)
iv. Check that the battery and wiring connections are clean and
tight.
v. Check the electrical ground connections.
vi. Check the apparatus fuel gauge; if it is below 1/4 of a tank, the
pump will not run. The fuel line for the pump is above the level
of 1/4 fuel tank level.
vii. Check if the pump has lost its prime. This may have been
caused by filling through the tank fill valve introducing air into
the pump. If this is the case, operate the primer pump.
3. FoamPro
The FoamPro System 1600 is an electric motor driven flow-based
proportioning system, which measures water flow and then injects the
proportional amount of foam concentrate to maintain the preset
percentage. The system will accurately deliver from 0.1 percent to 1.0
percent foam concentrate to the foam injector fitting.
Foam concentrate is injected directly into the water stream on the
discharge side of the water pump. It is fed as foam solution by the main
fire pump into a standard fog nozzle.
a. Foam Pump Priming Check:
i. Turn the CAL/INJECT valve to the CALIBRATE or FLUSH
position.
i. Provide a container to collect the output, which will
be coming from the foam pump.
ii. Turn the INJECTION RATE knob to the 1.0 percent
setting. Place the system into simulated flow and engage

the FoamPro system at the control module.
See Figure 7.)
Foam concentrate should begin flowing into the container. If concentrate is not
being pumped, check first to make sure the foam pump is running. If the pump
is running, but no concentrate is being delivered, the pump is most likely not
primed completely. If the pump does not prime within 20-30 seconds,
disengage the system by turning the switch off.
i. The foam concentrate should flow readily to the
pump.
ii. Once the foam flow is established, turn the system
off and turn the CAL/INJECT valve back to the inject
position. (See Figure 8.)

Next Revision (2) Date: 04/14/2027 Page 11 of 22
iii. Turn the simulated flow switch off. (See Figure 9.) If the
operator is still having difficulty priming the foam pump in
FoamPro system, do the following:
iv. Make sure foam concentrate tank shutoff valve is open.
(See Figure 10.)
v. Check to make sure there are no restrictions from the
concentrate tank to the inlet of the foam pump.
(See Figure 11.)

b. Normal System Operation:
When the FOAM switch is toggled into the ON position, the LOW
CONC light momentarily flashes on. This indicates the system is
ready to operate. The foam injection rate can be adjusted at any
time during operation to suit the conditions and/or concentrate
being used.
c. Display Messages:
Several safety features are provided to protect the foam
concentrate pump and motor and help diagnose problems in
system operation. The display method in the MODEL 1600/1601
utilizes the LOW CONC light.

Table 2
d. Simulated Flow Operation:
The simulated flow function of the system allows the operator to
control the foam pump manually. The water flow rate is factory
set at approximately 100 gpm; the percentage rate can be
adjusted at the control module. This function provides the manual
control requirement of NFPA. This function allows the operator
to employ the foam concentrate tank for cleaning or changing
foams. It also provides a means of checking the foam pump
without running the water pump.
Warning: When operating the FoamPro in the simulated flow
function, an outlet for the foam concentrate must be
provided. Otherwise, dangerous excessive
pressure may be built up in the apparatus water
piping and/or hoses.

4. Off-Road Operations or Four-Wheel Drive Operations:
Apparatus vehicle is equipped with front-wheel locking hubs. To put the
vehicle into four-wheel drive, the operator must get out of the vehicle to
place the hubs from the free position into the lock position. To return to
two-wheel drive, place the hub lock back into the free position. The
operator does not have to back up the vehicle to disengage the hub
locks. (See Figure 12.)
Figure 12
The transfer case knob is located to the right of the steering wheel on
the instrument panel. Use this knob to shift in and out of four-wheel
drive. (See Figure 13.)

Figure 13
a. Shifting Into Four-Wheel High:
Turn the knob to four-wheel high. This can be done at 3 mph or
less and when the operator is shifting out of four-wheel low. The
indicator light will flash while shifting. It will remain illuminated
when the shift is complete. (See Figure 14.)
Figure 14
b. Shifting Into Two-Wheel High:
Turn the knob to two-wheel high. This can be done at 3 mph or
less and when the operator is shifting out of four-wheel low.
c. Shifting Into Four-Wheel Low:
To shift to four-wheel low, the vehicle engine must be running,
and the vehicle must be stopped or moving less than 3 mph with
the transmission in NEUTRAL. The operator must wait for the
four-wheel low indicator light to stop flashing and remain
illuminated before shifting the transmission into gear.

Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 16 of 22
Note: Shifting the transmission into gear before the four-
wheel low indicator light has stopped flashing could
damage the transfer case. To avoid damaging the
vehicle, always wait for the four-wheel low indicator
light to stop flashing before shifting the transmission
into gear.
Note: If the operator tries to put the transmission in PARK (P)
while the transfer case is in four-wheel low, the
transmission may not go into PARK (P) and could
damage the vehicle. When parking the vehicle, make
sure the transfer case is in two-wheel high or four-
wheel high.
If the operator turns the knob to four-wheel low when the vehicle
is in gear and/or moving, the four-wheel low indicator light will
flash for 30 seconds and not complete the shift unless vehicle is
moving less than 3 mph and the transmission is in neutral. After
30 seconds, the transfer case will return to the setting last
chosen. If the vehicle is in gear and moving less than 3 mph, the
transfer case will shift to four-wheel high.
d. Shifting Out of Four-Wheel Low:
To shift from four-wheel low to four-wheel high or two-wheel high,
the vehicle must be stopped or moving less than 3 mph with the
transmission in neutral and the engine running. Operator must
wait for the four-wheel high or two-wheel high indicator light to
stop flashing and remain illuminated before shifting transmission
into gear.
Note: Shifting the transmission into gear before the four-
wheel high or two-wheel high indicator light has
stopped flashing could damage the transfer case. To
help avoid damaging the vehicle, always wait for the
four-wheel high or two-wheel high indicator light to stop
flashing before shifting the transmission into gear.
e. Do Not Forget to Unlock the Hubs:
After off-road usage, particularly in sand or mud, inspect the
underside of the vehicle for accumulated dirt at the propeller
shaft, axles, U-joints, brake rotors and calipers. Use a hose to
clean off any accumulation of dirt or mud. Check the exhaust
system and all exposed components for any sign of damage. If
Effective Date: April 2014 Mariano Caro, Equipment Supervisor

Next Revision (2) Date: 04/14/2027 Page 17 of 22
vehicle experiences unusual vibration after driving in mud, slush
or similar conditions, check the wheels for impacted material.
Impacted foreign material can cause a wheel imbalance.
Removing the foreign material from the wheels will correct the
situation. Always check the duals for rocks or other debris, and
also check the hydraulic brake lines for damage after driving off
road in four-wheel drive!
5. Winch Operations:
The single line pulling capacity is up to 12,000 pounds. Rating increases
with the use of a snatch-block. The cable is 3/8-inch diameter and 125
feet long.
To start, the operator should become familiar with Warn Winch and each
of its components. Practice using winch before using it.
a. Winching Safety:
i. Always inspect the wire rope condition before operating
the winch.
ii. Frayed, kinked, or damaged wire rope must be replaced
immediately. Loose or damaged winch installation must
be corrected immediately.
iii. Never leave the remote control plugged into the winch
while free spooling, rigging, or sitting idle.
iv. Never hook the wire rope back onto itself. This damages
the wire rope. Always use a choker chain, wire choker
rope, or tree trunk protector on the anchor.
v. Always be certain the anchor selected will withstand the
load and the strap or chain will not slip.
vi. Never engage or disengage the clutch if the winch is under
load, the wire rope is in tension or the wire rope drum is
moving.
vii. Always unspool as much wire rope as possible when
rigging. Double line or pick a distant anchor point.
viii. Never winch with less than five wraps of wire rope around
the drum. The wire rope could come loose from the drum.
Effective Date: April 2014 Mariano Caro, Equipment Supervisor
Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 18 of 22
ix. Never touch the wire rope or hook while in tension or under
load.
x. Never touch the wire rope or hook while someone else is
at the control switch or during winching operation.
xi. Never touch the wire rope or hook while the remote control
is plugged into the winch.
xii. Always stand clear of the wire rope and load and keep
others away while winching.
Always require the operator and bystanders to be aware
of stability during winching of the vehicle and/or load.
xiii. Always pass the remote control through a window to avoid
pinching the lead in door, when using the remote inside a
vehicle.
xiv. To avoid injury to hands or fingers:
a. Always wear heavy leather gloves when handling a
wire rope.
b. Never let the wire rope slip through your hands.
b. Avoid Winch and Equipment Damage:
i. Always avoid continuous side pulls, which can pile up wire
rope at one end of the drum.
ii. Always ensure the clutch is fully engaged or disengaged.
iii. Never use the winch to tow other vehicles. Shock loads
can momentarily exceed capacity of the wire rope and
winch.
iv. Always use care to not damage the frame when anchoring
the vehicle during a winching operation.
v. Never use the winch to secure a load during transport.

vi. Never submerge the winch in water.
vii. Always store the remote control in a protected, clean, and
dry area.
Figure 15
c. Winch Procedures:
The following steps describe how to recover the vehicle with
rigging a single line pull. Double or multiple line rigging
techniques follow the same basic steps but use a snatch block to
assist the process.
i. Put on gloves.
ii. Disengage Clutch: To allow free spooling of the winch
drum, rotate the clutch lever on the winch to disengage.
Free spooling conserves battery power.
iii. Free the Winch Hook and Attach the Hook Strap: Free the
winch hook from its anchor point. If not attached, attach
hook strap to the hook.
iv. Pull the Wire to the Anchor Point: Pull out enough wire
rope to reach the anchor point. To prevent wire rope
damage, ensure enough tension is in the wire to avoid the
wire becoming twisted or over wrap when it is slackened.
To prevent losing the end, hold the winch hook in the hook
strap while you work.

Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 20 of 22
v. Secure to the Anchor Point: Once the anchor point has
been established, secure the tree trunk protector or choker
chain around the object.
vi. Attach the Clevis/D-Shackle and Hook Strap: Attach the
shackle to the two ends of the strap or chain and through
the hook loop.
vii. Lock the Clutch: Lock the winch drum by rotating the
clutch lever on the winch to engage.
viii. Connect the Remote Control: Do not allow the remote-
control cord to dangle in front of the winch. If the operator
chooses to control the winch from inside the vehicle,
always pass the remote through a window to avoid
pinching the cord in the door.
ix. Place Wire Rope Under Tension: Using the winch switch,
slowly wind the wire rope until no slack remains. Once the
wire rope is under tension, stand well clear, and never step
over it.
x. Check Your Anchor: Make sure all connections are
secured and free of debris before continuing with the
winching procedure.
xi. Check Wire Rope: The wire rope should be neatly wound
around the spooling drum. Improper winding can cause
damage to the wire rope.
xii. Lay Something Over the Wire Rope: If the operator deems
it necessary, lay something midway between the winch
and the anchor point to absorb the energy should the wire
rope snap loose.
xiii. Make Operator’s Intentions Clear: Ensure everyone in the
immediate vicinity surrounding the winching operation is
completely aware of the operator’s intentions before the
operator pulls. Declare where the spectators should not
stand; never behind or in front of the vehicle, and never
near the wire rope or snatch block. The situation may have
other “no people” zones.

xiv. Begin Winching: With the winching vehicle engine on and
the light tension already on the wire rope, begin winching
slowly and steadily. Ensure the wire rope is winding
evenly and tightly around the spooling drum. For
additional assistance, the winched vehicle can be slowly
driven while being pulled by the winch.
xv. Disconnect the Wire Rope: Disconnect from the anchor.
xvi. Rewind the Wire Rope: The operator handling the wire
rope should walk the rope in and not let it slide through the
hands and control the winch at all times. Slight tension
should be maintained while spooling in the wire.
INFORMATION
This section intentionally left blank.
DEFINITIONS
1. Motor: Typically the winch motor is powered by the vehicle
battery. The motor provides power to the gear mechanism, which
turns the winch drum and winds the wire rope.
2. Winch Drum: The winch drum is the cylinder onto which the wire
rope feeds. The drum is driven by the motor and drive train.
Direction can be changed using the remote control (3/8-inch
diameter, 125 feet long).
3. Wire Rope: Wrapped around the winch drum and fed through the
fairlead, the wire rope is looped at the end to accept the hook’s clevis
pin.
4. Fairlead: When using the winch at an angle, the fairlead (or wire
lead) acts to guide the wire rope onto the spooling drum. It minimizes
damage to the wire rope while it goes through the winch mount or
bumper.
5. Gear Train: The reduction gear converts the winch motor power into
a large pulling force.

Current Revision Date: 04/14/2022 Section 310.012
Next Revision (2) Date: 04/14/2027 Page 22 of 22
6. Braking System: The brake is automatically applied to the winch
drum when the winch motor is stopped and there is load on the wire
rope. The brake prevents the winch from paying out line, which in
turn holds the vehicle in place.
7. Clutch: The clutch allows the operator to manually disengage the
spooling drum from the gear train, enabling the drum to rotate freely
(known as free spooling). Engaging the clutch locks the winch drum
back onto the gear train.
8. Control Box: Using electrical power from the vehicle’s battery,
the control box solenoids switch power to the motor, enabling the
operator to change the direction of the winch drum rotation.
9. Remote Control: The remote-control plugs into the winch control box,
allowing the operator to control the winch direction, as well as stand
well clear of the wire rope while operating the winch.
