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
Before each season, inspect scraper for wear. If
thickness of bottom of scraper is less than 1/16"
(1.6 mm), replace scraper (Fig. 15).
1.
Turn ignition key to OFF.
2.
Drain gasoline from fuel tank; refer to Draining
Gasoline, page 9.
3.
Tip snowthrower forward onto front housing.
4.
Remove (3) carriage bolts and lock nuts holding
scraper in place (Fig. 16). Remove scraper by
sliding it to right and down.
5.
Install new scraper to housing using carriage
bolts and nuts.
Replacing Drive Belt
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.
2.
Remove (3) self tapping screws, (2) capscrews,
(1) washer and (2) nuts securing belt cover to
snowthrower frame (Fig. 17). Set belt cover
aside.
3.
REMOVING BELT (Fig. 18)—Push down on
idler pulley allowing belt to be removed from
rotor pulley, brake arm assembly, and engine
pulley.
4.
INSTALLING BELT (Fig. 18)—Loop belt
around engine pulley, under idler pulley, over
roller, through brake assembly, and around rotor
pulley.
IMPORTANT: Belt must be on top of roller as
shown.
5.
Reinstall belt cover. Tighten fasteners securely,
but DO NOT OVERTIGHTEN.
Replacing Spark Plug
Before each snow season, check the spark plug. If
electrodes in center of plug are dark or have
deteriorated, install a new plug. Use an NGK
BPMR4A spark plug and set gap at .032" (.81 mm).
1.
REMOVE CONTROL PANEL
(Fig. 19)—Remove (3) capscrews securing
control panel to housing. Remove ignition key
and lift off panel, allowing it to hang on recoil
rope.
2.
REMOVE SPARK PLUG (Fig. 20)—Pull wire
off spark plug and remove plug. Examine the
plug and replace if cracked, fouled or dirty. DO
NOT SANDBLAST, SCRAPE OR CLEAN
SPARK PLUG BECAUSE DIRT MAY
RELEASE AND FALL INTO CYLINDER
CAUSING ENGINE DAMAGE.
3.
INSTALL SPARK PLUG—Set air gap (Fig. 21)
between electrodes at .032" (.81 mm). Install
plug and tighten to 15 ft–lb (20.4 N m). If torque
wrench is not used, tighten plug firmly. Push
wire onto spark plug and reinstall control panel
with (3) capscrews.
Adjusting Carburetor
The carburetor has been factory set, and no
adjustment is required.
Replacing Rotor Blades
Before each snow season, inspect rotor blades for
wear. When blade edge has worn to the wear indicator
hole (Fig. 22), 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.
