Maintenance
Keep snowthrower in safe operating condition by
cleaning the unit and tightening nuts, bolts, and
screws. 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 key switch to OFF.
2. CHECK ADJUSTMENT (Fig. 8 & 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.
Note: The control cable must always have
slack in it when in the disengaged
position.
3. ADJUST CABLE
A. Models 38412 & 38418 – Unhook spring
end from the top hole in control bar bracket
(Fig. 8). Slide spring cover off spring and
cable adjuster . 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. 9). (Positioning
cable end in a lower hole decreases gap;
positioning cable end in a higher hole
increases gap.) Reinstall spring cover over
cable adjuster and spring. Rehook spring
into top hole of control bar bracket (Fig. 8).
B. Models 38433 & 38438 – Unhook upper
cable end from hole in control bar bracket
(Fig. 10). Slide spring cover up cable to
expose cable adjuster (Fig. 15). 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. 10).
(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. 10).
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:
A. Models 38412 & 38418 – repositioning
spring end in bottom hole in control bar
bracket (Fig. 8).
B. Models 38433 & 38438 – repositioning
upper cable end into forward hole in control
bar bracket (Fig. 10).
Readjust cable (see steps 2–3).
IMPORTANT: Unnecessary use of forward or
bottom 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.
