Maintenance
Ground Drive Train Adjustment
1-2 in.
Ground drive chain tension is automatically spring-
adjusted, however the length of chain determines the
amount of chain wrap on the drive hub sprocket. Maintain
about 1 to 2 inches (2.54 cm to 5.08 cm)between chain
path at idler sprocket as shown above.
Hydraulic Surge Brakes (Optional)
Operation
Before towing the spreader, check the following.
1. Mare sure bearings at forward end of actuator are
greased.
2. Make sure breakaway lever is in the released position
(towards rear of machine).
3. Secure breakaway chain to tow vehicle. Make sure
there is enough slack in chain for turns.
4. Periodically check brake adjustment and master
cylinder reservoir fluid level.
Bleeding Brakes
1. Remove master cylinder reservoir cover.
2. Fill reservoir with clean DOT 3 brake fluid.
3. Loosen bleeder fitting at top of brake drum assembly
one turn.
4. Connect a bleeder hose to the fitting on the drum
and place end of hose in a clean container.
5. Operate safety breakaway lever to fill and bleed the
system. Add fluid as required.
DO NOT pump reservoir empty as air will be
introduced into the system.
6. Purge each cylinder one at a time until system is
completely free of air. Close bleeder screw as each
cylinder is purged.
7. Breakaway lever will pull up to a hard stop when all
air has been purged.
8. With breakaway lever pulled forward (actuator
extended), check for leaks in the hydraulic system.
Brake Adjustment
WARNING:
This procedure requires raising
the wheels of the spreader off of the ground.
Block and support the spreader securely to
prevent it from falling.
Make sure break drums are cool.
1. With wheels mounted, raise and block the spreader
until the wheels are off of the ground.
2. With actuator extended in the towing position, pull
the safety breakaway lever forward several times to
center the shoes in the drums.
3. Release the breakaway lever.
4. Turn adjustment on brake assembly until there is
a heavy drag. Back off adjustment until the wheel
turns freely. Adjust both shoes.
Repeat step 4 for each wheel.
