Draining Gasoline; Replacing Rotor Blades (Fig. 10-11) - Toro CCR POWERLITE 38177 Operator's Manual

6. Install spring cover over cable adjuster and
spring.
7. Hook spring into top hole of control bar bracket
(Fig. 5).
8. 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 in bottom hole in
control bar bracket (Fig. 5).
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, approved fuel
container.
3. After fuel is drained, start engine and let it run
until all fuel is consumed and engine stops.
Repeat the starting procedure two more times to
ensure all fuel is removed from the engine.
Note: This is the only procedure
recommended for draining fuel because
it allows all fuel to be removed from
fuel tank.
Replacing Rotor Blades
(Fig. 10-11)
Before each snow season, inspect rotor blades for
wear. When blade edge has worn to the wear indicator
hole (Fig. 10), the blades must be replaced to ensure
proper performance and prevent damage to underside
of snowthrower. Always replace both blades at the
same time.
Note: Whenever rotor blades are replaced,
scraper should also be replaced to
ensure proper snowthrower operation
and performance.
1. Stop engine. Remove key from switch. Pull wire
off spark plug.
2. REMOVING BLADE (Fig. 11)–Remove (4)
Torx screws (Bit No. T27), (2) capscrews, and
(6) locknuts securing blade to rotor shaft
assembly.
3. Slide the blade out from between the blade
supports (Fig. 11).
4. INSTALLING NEW BLADE–The rotor blades
are made of laminated rubber. Examine the edge
of a blade to see the difference in layer thickness
(Fig. 11).
Both blades must be installed with the thick
layer on the inside of the curve, and the wear
indicator holes must be on the drive belt cover
side (Fig. 11). If one of the blades is installed
with the thick layer on the outside of the curve
and the other blade installed with the thick layer
on the inside of the curve, the blades will be
unbalanced, causing the snowthrower to "hop"
or "bounce."
5. Insert new blade between blade supports. Secure
center of blade to blade supports with (2)
capscrews and (2) locknuts. Position screw heads
on thick layer side of blade. Curve blade and
secure it with remaining (4) Torx screws and
locknuts (position screw heads on thick layer
side of blade). Tighten all screws and nuts
securely.
