Tooth Sharpening Guidelines
1) Obtain an unused tooth for comparison.
2) Discard any tooth that has lost more than 1/8” of original
bite, whether lost through usage or grinding.
3) Grind off a minimal amount from the end, just enough
to restore the original taper and radius on the end. The
end of the cemented carbide tip and the end of the steel
shank should be flush after grinding.
Engine Combustion Air Cleaner -
Check
A dirty air cleaner will restrict air flow to the carburetor,
reducing engine performance. If you operate the engine in
very dusty areas, clean the air filter more frequently. Do not
operate the engine without an air filter, or with a damaged
air filter as this would allow dirt and abrasive debris into the
engine causing rapid wear and reduced engine life.
To check the air filter, remove the air cleaner cover and inspect
the condition of the dual filter elements. Always replace dirty
or damaged filter elements.
1) 1. Remove the top wing nut from the air cleaner cover,
and remove the cover.
2) 2. Remove the second wing nut from the air filter, and
remove the filter.
3) 3. Remove the foam outer filter from the paper inner
filter.
4) 4. Inspect both air filter elements, and replace them if
they are damaged. Always replace the paper air filter
element at the scheduled interval or sooner if operated
in very dusty areas.
5) 5. Clean the air filter elements if they are to be reused:
a. Paper air filter element:
Tap the filter element
several times on a hard surface to remove dirt, or blow
compressed air (10-30 psi max) through the filter element
from the inside. (Never try to brush dirt; brushing will
force dirt into the fibers).
b. Foam air filter element:
Clean in warm soapy water,
rinse and allow to dry
6) Remove the 3 pan-head screws from the pre-cleaner
cap, then remove the cyclone housing and air guide.
Wash the parts with water, dry them thoroughly, and
reassemble them.
7) Be sure to install the air guide as shown in the illustration.
8) Install the cyclone housing so the air intake tab fits into
the groove in the pre-cleaner cap.
9) Wipe off any dirt from the inside of the air cleaner base
and cover using a moist rag. Be careful to prevent dirt
from entering the air duct that leads to the carburetor.
10) Place the foam air filter element over the paper element,
and reinstall the assembled air filter. Be sure the gasket
is in place beneath the air filter. Tighten the air filter
wing nut securely.
11) Install the air cleaner cover and tighten the wing nut
securely.

Park Brake Adjustment - Check
For coarse adjustment, loosen the jam nuts (1) on the hub at
the lower end of the cable. Adjust the jam nuts as necessary
and re-tighten.
For fine adjustment at the Hand Lever, first remove the set
screw (2) and turn the brake lever knob (3) clockwise, one
revolution while the brake lever is in the released position
as shown. Then apply the brake lever to check operation.
The wheel should lock completely. Repeat the adjustment
if necessary.
