PART 8: MAINTENANCE AND SERVICE
PB1319 (CAT. NO. 5296 ) —149— 22-01691 (R02/02)
Removing and Installing Batteries
Whenever you have to install a battery or remove one, follow these
guidelines for the safety of yourself and the battery.
• Ensure all switches on the vehicle are turned Off.
• Disconnect the ground cable first when removing a battery.
• Connect the ground cable last when installing a battery.
Fuel System
Location of Fuel Shut-off Valves: Fuel shut-off valves for the fuel
crossover line are on the bottom of the secondary fuel tank, at the
crossover line connection. They are optional on the primary fuel tank.
Specification: Use only diesel fuel as recommended by engine manu-
facturers.
Fuel Filters
Please follow these recommendations when you are changing your
fuel filters or strainer elements. Your engine will run better and last
longer if you do. See the engine manufacturer’s recommendations for
proper water and micron requirements.
1. When removing filters, cover any electrical equipment and wiring
that might get soaked with fuel. Diesel fuel may permanently dam-
age electrical insulation.
2. When installing spin-on (throwaway) filters, hand tighten them only
to 1/2 to 2/3 turn after gasket contact. Mechanical tightening of
these filters may distort or crack the filter head.
CAUTION: Always reinstall the battery compartment cover
(step) before entering the cab. Without the battery cover
you could slip and fall, resulting in possible injury to your-
self.
WARNING! A mixture of gasoline or alcohol with diesel
fuel in the presence of an ignition source (such as a cig-
arette) could cause an explosion. You could be seri-
ously injured. Use only the recommended diesel fuel.
CAUTION: If anyone ever pours gasoline into your fuel
tank, drain the entire system. Otherwise, the pump and
engine will be damaged. Don’t try to dilute the gasoline
by adding diesel fuel (See Warning above).
