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.
NOTE: A knife gauge has been provided with your machine. It is 1/16
th
” thick and should be used to set the
correct gap between the knife and wear plate.
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 bearing. 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 the 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 chipper 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.
7. Take the knife gauge and slide between the knife and wear plate.
If
the gap is set correctly, the knife gauge will lightly touch both the
knife and wear plate. If the gap is too small, you will not be able
to
get the gauge between the knife and the wear plate. If the gap
is
too large, there will be excess room between the knife gauge,
knife and wear plate. 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.
8. 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.
9. 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.
NOTE: Proper gap setting is critical to the proper operation of your machine.
