Maintenance
Normally, the only maintenance required is cleaning
the unit and tightening nuts, bolts, and screws.
However, the scraper, drive belt, rotor blades, and
spark plug should be checked once a year.
Adjusting Control Bar
(Fig. 10-11)
Periodically check control bar for proper adjustment.
1.
Turn ignition key to OFF.
2.
CHECK ADJUSTMENT (Fig. 10)–Move
control bar back toward handle until slack in
cable is removed. Gap between control bar
bracket and handle should be approximately
1/16"–1/8". If cable is too loose or too tight,
proceed to step 3 for adjustment procedure.
3.
ADJUST CABLE (Fig. 11)–Unhook upper cable
end from hole in control bar bracket. Slide
spring cover up cable to expose cable adjuster.
Unhook cable end from cable adjuster and
reposition in a higher or lower hole on adjuster
as required to attain proper gap of 1/16"–1/8".
Reinstall upper cable end into rear hole (hole
with arrow) in control bar bracket. Slide spring
cover over cable adjuster and recheck
adjustment.
4.
After extended use the drive belt may wear and
proper belt tension may not be maintained,
Improper belt tension causes belt slippage and
decreases the snowthrower's performance under
a heavy load. Belt slippage may occur after 2-3
seasons of normal usage (10-15 hours). If drive
belt slips (continuous squealing noise) under
heavy load, increase belt tension by
repositioning spring end into forward hole in
control bar bracket. Readjust cable (see steps
2-3).

IMPORTANT: Unnecessary use of forward
adjusting hole in control bar bracket reduces
drive belt life. Occasional belt slippage
(squealing) may occur in extremely wet
conditions due to moisture in drive system. To
remove moisture, start rotor and operate
under no load for 30 seconds. Once moisture
is removed, belt should not slip.
Draining Gasoline
1.
Stop engine. Remove key from switch.
2.
Remove cap from fuel tank and use a pump-type
syphon to drain fuel into a clean gas can.
Note:
This is the only procedure
recommended for draining fuel.
Replacing Scraper (Fig. 12-13)
Before each season, inspect scraper for wear. If
thickness of bottom of scraper is less than 1/16"
(1.6 mm), replace scraper (Fig. 11).
1.
Turn ignition key to OFF.
2.
Drain gasoline from fuel tank; refer to Draining
Gasoline, page 11.
3.
Tip snowthrower up onto its nose. Remove
carriage bolts and locknuts holding scraper in
place (Fig. 13). Remove scraper by sliding to
right and down.
4.
Install new scraper to housing with carriage bolts
and nuts.
Replacing Drive Belt
(Fig. 14-15)
Inspect drive belt before each season. If ribs on inside
of belt are damaged or belt is worn, replacement is
necessary.
1.
Turn ignition key to OFF.
