side (Fig. 9). 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.”
2.
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.
3.
Repeat steps 1–4 to replace other blade.
Replacing Scraper
Before each season, inspect scraper for wear. When
wear indicator groove is worn away (Fig. 10), replace
scraper to prevent damage to underside of
snowthrower.
1.
Stop engine. Remove key from switch. Pull wire
off spark plug.
2.
Tip snowthrower forward onto front housing.
3.
Remove (3) screws holding scraper in place
(Fig. 11). Remove scraper.
4.
Secure new scraper to housing with (3) screws.
Replacing Drive Belt
After extended use, drive belt may wear and require
replacement. If drive belt continues to slip under a
heavy load or the rotor does not turn, check to see if
belt is severely worn.
1.
Stop engine. Remove key from switch. Pull wire
off spark plug.
2.
Remove (3) self tapping screws, (1) capscrew,
(1) washer, and (1) nut securing left side cover to
snowthrower frame (Fig. 12). Remove cover.
3.
REMOVING BELT (Fig. 13)—Pull idler pulley
up slightly while pulling out on belt. Allow
pulley to gradually release when it can move
past the belt. Rotate rotor with left hand and
work belt off rotor pulley with right hand. Belt
then slides easily off drive pulley.
4.
INSTALLING BELT (Fig. 14)—Loop belt
around drive pulley. While holding belt with
right hand, slip belt onto rotor pulley and rotate
rotor with left hand until belt is completely on
rotor pulley. Make sure long end of idler spring
is hooked in housing notch and round end of
spring is hooked on pin on back of idler pulley.
Lift up idler pulley arm assembly, squeeze belt
together, and route belt under idler pulley.
5.
Reinstall left side cover. Tighten fasteners
securely, but DO NOT OVERTIGHTEN.
Replacing Spark Plug
Check spark plug yearly or every 100 operating
hours. If electrodes in center of plug are dark or have
deteriorated, install a new plug. Use a Champion
RCJ8Y spark plug or equivalent and set gap at .030”
(.76 mm).
1.
REMOVE CONTROL PANEL
(Fig. 15)—Remove (2) screws securing control
panel to housing. Remove ignition key and lift
off panel, allowing it to hang on recoil rope.
2.
REMOVE SPARK PLUG (Fig. 16)—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. 17)
between electrodes at .030” (.76 mm). Install
plug and tighten to 15 ft–lb (20.4 N
m). If torque
wrench is not used, tighten plug firmly with
wrench by hand; DO NOT OVERTIGHTEN.
Push wire onto spark plug and reinstall control
panel.
