WINDSHIELD WIPERS
WIPER ARM REMOVAL & INSTALLATION
To replace the wiper arm assembly if damaged, follow the
procedure outlined below.
NOTE:
Before removing any wiper arm, it is first necessary to
operate the wipers briefly, stopping the blades in the normal park
position.
First install a .1 pin in hole located on wiper arm above the
rubber boot in order to keep spring in stationary position during
reinstallation. Remove the cap nuts, which secure the wiper arm
and idler arm to the wiper and idler shaft, respectively. Remove
the wiper arm and place new arm over wiper shaft and make
sure the new arm is replaced in the same position as the old arm
was removed. Place original cap nuts on shafts and tighten.
WASHER SOLUTION RESERVOIR
The windshield wipers on this unit are intermittent and operate independently of each other and the
controls of each operate the same. Turn the knob clockwise to activate. The rheostat type switch allows you to
adjust the cycle of the wipers faster or slower depending on rain condition.
If the windshield needs cleaning, it may be necessary to use the onboard washer. To activate it, simply
push the control knob. This will spray the cleaning fluid onto the windshield during wiper operation. The
cleaning fluid is a 50-50 mixture of methanol alcohol and water. NOTE : Always use this mixture to avoid
freeze-up. Never use 100 percent water as it may freeze on windshield during operation limiting driver vis-
ibility.
The windshield washer reservoir is located in the right hand side of the front center emergency equip-
ment compartment. To open the compartment grip the hand hole located directly below the mechanical le-
vers on the heater control panel and pull outward. This allows access to the filler spout. Be sure there is ample
supply of cleaning fluid at all times.
WIPER ASSEMBLY REPLACEMENT
To replace wiper assembly, loosen lock nut, remove
screw and pull wiper assembly loose from wiper arm.
Replace the wiper assembly and use original screw and
lock nut. Tighten lock nut securely, but do not tighten
enough to compress the saddle. Blade must be free to
move on axis (machine screw) and within the saddle.
Threading the lock nut until flush with machine screw
end will give a secure and serviceable installation.
