Apply 2 medium -- wet coats of Duponts
222S Adhesion Promoter over the entire
area to be painted, with a 5 minute flash in
between coats.

To apply the texture coat, use Duponts
1854S

Tuffcoat

Primer.

The

proper

technique to do this is to spray the Tuffcoat
Primer using a pressure pot and use about
2--5 pounds of air pressure. This will allow
the primer to splatter causing the textured
look. Note: You must be careful not to put
too much primer on at one time, this will
effect the amount of texture that you are
trying to achieve. Allow the texture coat to
flash for 20 minutes or until dry to touch.

10.

Apply any of Duponts Topcoat Finishes
such as Imron

or Centari

according to

the label instructions.

Note: To re--topcoat the textured surfaces when

sheet metal repairs are not necessary,
follow steps 1, 2, 4, 5, 6, 8 and 10.

COOLING FAN DRIVE

The heat exchanger or cooling fan is driven by a belt
arrangement directly from the engine. Inspect the en-
gine fan belt weekly or at 50 hour intervals. Refer to
engine section for proper belt adjustment procedures.

BRAKE SYSTEMS (Hydraulic Only)

This compressor is equipped with mechanical parking
brakes and hydraulic surge brakes. The maintenance
of these brake systems is required to ensure safe op-
eration of this compressor.

Every six months visually check the brake shoes for
proper operation and deterioration. The common au-
tomotive standards and procedures would apply in re-
placing the brake shoes.

When replacing brake cables it is necessary to adjust
the brake shoes before adjusting the parking brake
system. To adjust the shoes, remove the rubber hole
plug in the brake backing plate and rotate the star ad-
justing nut until you cannot rotate the wheel by hand.

Then back off the adjustment ten to twelve (10--12)
notches.

Note: Always rotate wheel in direction of forward trav-
el only. Replace hole plug and proceed to next wheel
and repeat procedure.
Adjust parking brakes after all brake shoes have been
adjusted by:

1. Turning knob on brake lever until lever is perpendic-
ular to bracket when in “OFF” position. Wheels should
turn freely.

2. With lever in “OFF” position, adjust brake cables un-
til each has approximately the same tension. Wheels
should turn freely.

3. Move lever to “ON” position. Check each wheel to
see that it will not rotate. If all wheels will rotate, adjust
knob on lever until brakes are fully applied. If one or
two wheels will still rotate, adjust the cables for those
wheels and recheck.

4. After brakes are adjusted, move lever to “ON” posi-
tion and apply grease to cable strands from conduit six
inches toward lever. This is to prevent dirt from getting
into the conduit.

NOTE:

New cables will stretch and therefore should

be readjusted after the first week of use.

Every six months, apply a multi--purpose grease to the
fittings on the brake actuator.

Before servicing the hydraulic surge brake system,
the actuator, reservoir, wheels and underside of frame
should be cleaned to prevent dirt and other contami-
nants from entering the hydraulic system.

Whenever a brake line hose, tube or fitting is removed/
replaced, the hydraulic brake system must be bled of
air to ensure proper brake operation. Bleed the
brakes, at each wheel cylinder, in the following order:
RH rear; LH rear; RH front; LH front (front is the hitch
end; instrument panel is on LH side), while maintain-
ing brake fluid level in reservoir. Use brake fluid con-
forming to DOT 3 or DOT 4 specifications.
