Check rear battery retainers for damage or missing bolts. Check that all bolts are tight.

Check front battery retainer for damage, and proper adjustment. Check that front battery retainer is secured in position by two bolts on each side of the truck. Check that all bolts are tight.

Check to make sure that all holes and openings that could allow leakage from the battery comp- artment down into traction control and pump motor compartments are sealed with RTV-type silicone sealer (arrows).

Check battery cover hinges, springs and rollers for damage, and security of mounting. Fig. 22183

DO NOT SMOKE OR HAVE OPEN FLAMES OR SPARKS IN BATTERY CHARGING AREAS OR NEAR BAT- TERIES.AN EXPLOSION CAN RESULT AND CAUSE INJURY OR DEATH.

NEVER WASH THE BATTERY WHILE IT IS IN THE TRUCK

BATTERY SAVER and CLEANER, Clark Part No. 886398, may be used to clean and protect the truck battery.

NEW TRUCK BATTERIES:

Spray a light coat of BATTERY SAVER and CLEANER over the entire battery surface. Do not wipe off.

OLD TRUCK BATTERIES:

Apply a coat of BATTERY SAVER and CLEANER to entire battery surface. Allow to set for approximately 30 seconds, then wipe thoroughly with a rag. Chemical reaction will dissolve corrosion and rust. After cleaning, apply a second coating for protection. This will prevent the start of corrosion on cables and terminals.

Check BATTERY VENTS for obstruction. Cap vents must be open at all times. If cap vents are plugged, they may be washed in a solution of baking soda.

SULFURIC ACID THE BATTERY CONTAINS CORROSIVE ACID WHICH CAN CAUSE INJURY. IF ACID CONTACTS YOUR EYES OR SKIN, FLUSH IMMEDIATELY WITH WATER AND GET MEDICAL ASSIS- TANCE. Check SPECIFIC GRAVITY of battery fluid. Be sure to check at least six battery cells with a hydrometer. Specific gravity should be no less than 1.250. Fig. 12913

Remove floorboard fasteners and floor- boards from the truck.

Open the traction controller compart- ment door. Check the controller mounts for damage.

Open the hydraulic pump motor compart- ment door. Check hydraulic pump intake and high pressure hose lines for signs of leaking, wear and obstruction from sharp bending or kinking. Check that the electrical system air cooling fan housing, intake screen, housing-to- motor seal and housing bolts all are in place and tight. Fig. 22186

Air Clean The Truck

Use an extension on the air hose similar to that shown here. Use clean, dry air and restrict air pressure to [207 kPa] or 30 P.S.I. Wear suitable eye protection and protective clothing.

OR DRYING WITH AIR PRESSURE. REDUCE PRESSURE TO [207 kPa] 30 PSI. OEiiRIS RtMOVEO WITH AIR PRESSURE CAN CAUSE INJUR Fig. 15301

Air clean the area under the floor- boards. Clean off the accelerator, seat linkage and all other linkages. Also air clean the fins on the bottom of the pump control.

Air clean the drive motor and air vent- ilation screen openings. Check all motor electrical connections for tight- ness. Refer to GROUP 40, Section 5 for torque specification.

Also check for worn or frayed power cables and obvious signs of loose connections, such as burned terminals.

Air clean the battery compartment, and front and rear of drive motor.

Remove the mounting bolt and swing out the traction control. Air clean the outside of the control box, all term- inals and all cooling openings and passages. Air clean field weakening resistor and terminals, if installed.

Note: The rear cover panel snaps in place for easy removal for clean- ing of heat sink cooling fins. Refer to Fig. 22193, Page 28. Fig. 22189
