5-19.1 Fan Clutch
Engines equipped with a fan clutch will provide airflow to cool the engine when one or more of the following
conditions are met.
•
The engine coolant or air intake temperature reaches the engine manufacturer’s preset temperature for fan
engagement.
•
Placing the truck in “pump mode” may activate the fan clutch.
•
Activation of any generator PTO drive may engage the fan clutch.
5-20. Starting Engine Using Power From Another Vehicle
If the battery charge is insufficient to crank the engine, the following procedure may be used to supplement battery
power.
1. To prevent shorting of the electrical system, remove metal rings, watches, or other metallic accessories and do
not allow metal tools to contact positive terminal of battery.
2. Position the vehicles so the jumper cables will reach easily between the batteries. Do not allow the vehicles to
touch.
3. Turn off all electric motors and accessories in each vehicle. Turn off all lights not needed to protect the vehicles
or to light the work area. In each vehicle, stop the engine, turn off the warning light master switch.
4. Apply the parking brake and shift the transmission to
N
(Neutral) in both vehicles.
5. Connect the first jumper cable from the positive (+) terminal of the dead battery or the positive (+) terminal of
the jump-start stud to the positive (+) terminal on the booster battery.
Fan clutches can engage and fan blades can spin without warning. Keep hands, hair, and clothes away
from fan. Never operate the engine with personnel in the vicinity of the fan as the fan may engage
without warning. Failure to heed this warning may lead to personal injury or death.
Pierce Custom Chassis have a 12-volt negative ground electrical system. Before using jumper cables,
make sure the booster vehicle also has a negative ground system (negative terminal attached to a
metal part of the vehicle). If unsure of the booster vehicle’s voltage or ground, do not attempt to jump
start as personal injury or severe damage to the electrical system may result.
The following procedures must be performed exactly as outlined. Otherwise injury to the face, eyes,
body, limbs, and respiratory system could result from fire or acid due to battery explosion. Property
damage could also result.
To avoid damage to vehicle electronic components, voltage supplied to a vehicle’s electrical system
must not exceed 16.0 volts.
