IMPORTANT: STORE SNOWTHROWER
IN OPERATING POSITION ON ITS
WHEELS. TIPPING OR STORING UNIT
FORWARD ONTO FRONT HOUSING
MAY CAUSE HARD STARTING.
Maintenance
NOTICE: Maintenance, replacement or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, to obtain no
charge repairs under the terms and
provisions of the Toro warranty
statement, any service or emission
control part repair or replacement
must be performed by an
Authorized Toro Service Dealer.
General 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
Periodically check control bar for proper adjustment.
1. Turn ignition key to OFF.
2. CHECK ADJUSTMENT (Fig. 9)—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.
Note: The control cable must always have
slack in it when in the disengaged
position.
3. Unhook upper cable end from hole in control bar
bracket (Fig. 6). Slide spring cover up cable to
expose cable adjuster (Fig. 10). Unhook Z fitting
from cable adjuster and reposition Z fitting in a
higher or lower hole on adjuster to obtain proper
gap of 1/16”–1/8” between control bar bracket
and handle (Fig. 6). (Positioning cable end in a
lower hole decreases gap; positioning cable end
in a higher hole increases gap.) Reinstall spring
cover over cable adjuster. Reinstall upper cable
end into rear hole in control bar bracket (hole
with arrow) (Fig. 6).
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 upper cable end into forward hole
in control bar bracket (Fig. 6). 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. 11-12)
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.
