SECTION V – MAINTENANCE & STORAGE

IMPORTANT: The knife should be checked for sharpness and the bolts attaching them to the flywheel for

tightness every 8-10 hours of operation.

IMPORTANT: Every time you perform maintenance or any kind of service or check on the knife, be sure to

check the gap between the knife and wear plate for proper setting.

If the cutting mechanism strikes any foreign object or if your machine should start making an unusual noise or is

vibrating, stop the engine, disconnect the spark plug wire(s) from the spark plug(s). Allow the engine to cool

before you:

a. Inspect and examine for damage.

b. Check for loose nuts, bolts or parts.

c. Repair or replace any damaged parts before restarting and operating the machine.

1. When not in use, your shredder/chipper should be stored out of the reach of children. Be sure that there are no

gasoline fumes in the storage area. For long periods of storage (over the winter), refer to the engine owner’s

manual.

2. After every 8 hours of operation, lubricate the chipper side and drive side bearings. To do this, wipe all dirt,

etc., from the grease fittings with a clean cloth, then apply no more than 3 shots of quality general-purpose

grease with a hand-pumped grease gun. Over lubrication can also damage bearings. Also, check the bearing

collar set screws regularly to be sure they are tight. If they are loose, reset them with Loctite 243, obtainable at

any hardware store.

3. You will find information included referring to operation and maintenance of the engine. Look it over carefully.

BE CERTAIN TO ADD OIL BEFORE STARTING IT.

4. When the steel chipping knife needs replacing or sharpening, refer to the section on removal, sharpening and

re-installation.

5. Care must be exercised when sharpening the knife to maintain the correct bevel and a straight edge. Refer to

sharpening directions. When you install a knife, the clearance between the knife and wear plate must be

checked and set. This clearance or gap should be set to 1/16” (see figure 1).

6. To adjust this clearance, loosen the three ¼” nuts and bolts holding the wear plate in place. The wear plate

can be slid up or down (in or out) to achieve the correct gap setting. Tighten the nuts and bolts when the wear

plate is in the correct position. Be certain the flywheel rotates without hitting anything before starting the

chipper.

7. If the gap between the wear plate and the knife is not set correctly, you will have excessive vibration when

chipping and the blade will seem to be dull. This should be checked every 8-10 hours of operation.

8. If at any time it becomes necessary to disassemble the chipper for repairs, the chipper disk must be re-installed

in exactly the same position on the rotor shaft.
