DEPTH BAR
See Figure 6. The depth bar setting determines the depth
of tilling. To till 4 to 6 inches deep, install the bar mount­
ing pind'n 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 DEEPER
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 owner's manual for adjustment pro­
cedures.
PULLEY ALIGNMENT
See Figure 10. 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 nec­
essary remove blower housing and clean.
1. When clutch disengaged (handle released), idler pulleys
should be no closer than 1/4-inch from frame and all belt
stops must be firmly gripping the drive belts.
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 Beit Stop
Adjustment.
3. See Figure 5. If clutch does not operate as described
above in steps 1 and 2, loosen wire clamp setscrew and ad­
just wire clamp on forward or reverse control rod to obtain
required spring tension.
SCRAPERS
Loosen scraper mounting nut and adjust scraper in its slot
to 1/8-inch clearance above wheels. Tighten nut when
adjustment completed.
CAUTION
Continued operation with a clogged cooling system
causes severe overheating and possible engine damage.
