ENGLISH

SERVICE & MAINTENANCE

WARNING

BEFORE INSPECTING OR SERVICING ANY PART OF THIS MACHINE, SHUT OFF POWER SOURCE, DISENGAGE THE

HYDRAULICS, OPEN SHIELD AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.

5.11.1 DRIVE BELT

Check the condition of the drive belt annually or after

every 25 hours of operation, whichever comes first. If

the belt is cracked, worn, frayed, or stretched, replace it.

Replace belt with original banded belt type only. Do not

use single type belts.
To replace the belt:
1. Lift up the engine hood.
2. Remove idler pulley by loosening the 1/2" mounting

hardware.

Lift belt idler pulley off the idler arm weldment.

4. Remove the hydraulic pump belt by loosening the

bolts on the hydraulic pump.

5. Remove the drive belt from the pulleys and discard.
6. Inspect pulleys for wear. Replace the pulleys if they

are cracked or worn so that the belt contact area is

not smooth and flat.

7. Install new belt on pulleys and lower belt idler.
8. Reinstall the belt idler pulley into the idler arm

weldment using the 1/2" hardware. Tighten bolt to

proper torque.

9. Check pulley alignment by placing a straight edge

across the face of both pulleys. Adjust the lower (engine)

pulley if necessary to bring them into alignment.

10.

Check belt tension and adjust if needed. The belt

deflection at the center of the belt should be 7/16"

with a 20 lb. load. If necessary, adjust spring tension.

11. Shut engine hood.

Feeding too large or too much material at once may plug

the chipper. To clear a plugged rotor, proceed as follows:
1.

Lift the engagement handle and turn off engine key

switch. Allow all moving parts to come to a complete

stop.

2. Remove the two 3/8" retaining bolts holding the

access cover to the chipper frame and lift up access

cover.

3. Remove the lock pin from storage position (see

Figure 5.6).

Turn check valve clockwise to engage the jack pump.

5. Pump the handle to raise the feed roller until the lock

pin position aligns with one of the support bracket

holes.

6. Secure the position by putting the lock pin through the

support bracket and lock pin position.

7. Clean the debris away from the chipper rotor. Turn

the rotor by hand to be sure it is free to rotate. Be

careful to avoid the chipper blades when cleaning out

the debris.

8. Remove the lock pin and put it back in storage

position.

LEAVING THE LOCK PIN IN ANY OTHER

POSITION MAY INTERFERE WITH FEED ROLLER

OPERATION.

9. Turn the check valve counterclockwise to disengage

the pump and lower the jack.

10. Close access cover and replace bolts.
11. Start the engine. Follow start up procedures in

Section 4.1.
