TO ADJUST SCRAPER BAR
After considerable use, the metal scraper
bar will have a definite wear pattern. The
scraper bar may have to be returned to its
original lower setting to maintain the original
performance level. To adjust:
• Position the snow thrower on a level sur­
face.
• Loosen the carriage bolts and nuts secur­
ing the scraper bar to the auger housing.
• Adjust the scraper bar to the proper posi­
tion.
• Tighten the carriage bolts and nuts, mak­
ing sure that the scraper bar is parallel
with the working surface.
• For extended operation, the scraper bar
may be reversed. If the scraper bar must
be replaced due to wear, remove the car­
riage bolts and nuts and install a new
scraper bar.
/K CAUTION: Be certain to maintain
proper ground clearance for your particular
area to be cleared. Objects such as gravel,
rocks or other debris, if struck by the impel­
ler, may be thrown with sufficient force to
cause personal injury, property damage or
damage to the snow thrower.
TO ADJUST THE CLUTCH CONTROL
CABLES
Periodic adjustment of the cables may be
required due to normal stretch and wear on
the belts. To check for correct adjustment,
the control lever must be in the full forward
position, resting on the plastic bumper. The
control cables are correctly adjusted when
the center of the "Z" fitting is in the center of
the hole and there is no droop in the cable.
See figure below.

If adjustment is necessary:
• Remove fuel from tank, and stand blower
on end.
• Disconnect the "2" fitting from drive lever.
• Pull rubber boot off the top of the spring.
Push the cable through the spring (see
figure below) to expose the threaded por­
tion of the c^le.

• Hold the square end of the threaded por­
tion with pliers and adjust the locknut in or
out until the excess slack is removed.
• Puli the cable back through the spring
and connect the cable. Do the same for
the other lever cable, if needed.
NOTE: Whenever the traction drive or au­
ger belts are adjusted or replaced, the
cables will need to be adjusted.
TO ADJUST BELTS

i
If your snow thrower will not discharge
snow, check the control cable adjustment, if
it is correct, then check the condition of the
auger drive belt. It may be loose or dam­
aged. If it is damaged, replace it (see To
Replace Belts paragraph on page 19).
TRACTION DRIVE BELT
The traction drive belt (see first figure on
page 19) has constant spring pressure and
does not require adjustment.
• Repiace the traction drive belt if it is slip­
ping (see To Replace Belts paragraph on
page 19).
