CLUTCH
FIRST 5 HOURS OF OPERATION
1. When clutch disengaged (handle released), idler pulley
should be no closer than 1/4-inch from frame and all belt
stops must be firmly gripping the drive belt.
2. When clutch engaged (handle compressed), idler pulley
must press in on belt enough to remove belt from contact
with belt stops. Approximately 1/8-inch clearance between
belt stop and belt should be maintained (See Belt Stop
Adjustment).
3. See Figure 6. If clutch does not operate as described
above in steps 1 and 2, loosen wire clamp setscrew and adjust
wire clamp on control rod to obtain required spring tension.
DEPTH BAR
See Figure 7. The depth bar setting determines the depth
of tilling. To till 4 to 6 inches deep, install the bar moun­
ting pin in the second or third hole from the top. Pull out
the hairpin clip to change pin location. Be sure to install
the bar with the digging tip as shown. THE DEEPER
THE DEPTH BAR IS SET INTO THE SOIL, THE DEEP­
ER THE TINES WILL DIG.
CARBURETOR
Minor carburetor adjustments may be required to com­
pensate for differences in fuel, temperature, altitude and
load. See your engine owners manual for adjustment pro­
cedure.
PULLEY ALIGNMENT
See Figure 12. Visually check alignment of engine, idler,
and driven pulleys. Pulleys must be aligned as closely as
possible or belts will be stretched and worn excessively.
Loosen engine and/or driven pulley setscrews and align
pulleys. Tighten setscrews securely.
MAINTENANCE
Read the engine owner's manual thoroughly.
AFTER EACH USE
Grass, dirt, or chaff may clog engine cylinder head fins and
blower housing. Check for clogged condition and if neces­
sary, remove blower housing and clean.
CAUTION
See Figure 10. Change engine oil as follows:
a. Run engine for a few minutes to warm engine oil.
b. Remove oil drain plug and allow oil to completely
drain from engine.
c. Replace oil drain plug securely.
d. Remove dirt around engine oil filler plug.
e. Remove engine oil filler plug by turning counter­
clockwise.
f. Fill with SAE 30 grade MS oil until level with top of
neck. Crankcase capacity is 1-1/4 pints.
g. Reinstall engine oil filler plug securely.
EVERY 5 HOURS OF OPERATION
See Figure 13. Check and add worm drive housing gear oil
as follows:
a. Remove worm gear housing oil filler plug.
WORM GEAR HOUSING
OIL-FILLER PLUG
Figure 13.
CAUTION
There is a filter in a vent hole located at rear of worm
drive housing. Do not remove this filter for any
reason.
b. Oil level should be level with plug hole when tines
are resting on ground.
c. If oil is required, tip tiller back until handles rest on
ground. Add a small amount of special worm gear oil
through plug hole and slowly lower tiller until tines rest on
ground. Oil should be level with plug hole, if not, repeat
procedure. Do not overfill.
Continued operation with a clogged cooling system
causes severe overheating and possible engine damage.
