TO ADJUST SCRAPER BAR
After consiclerable use, the metal scraper bar will have a definite wear pattem. 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 thecar- riage bolts and nuts and install a new scraper bar.
A_ 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 injuPj, 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.

Cable spring
•Hold the square end of the threaded por- tion with pliers and adjust the Iocknut in or out until the excess slack is removed.
•Pull 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
AUGER DRIVE BELT
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.
•Replace the traction drive belt if it is slip- ping (see To Replace Belts paragraph on page 19).
