SERVICE AND ADJUSTMENTS
ALWAYS DISCONNECT THE SPARK PLUG WIRE AND TIE BACK AWAY FROM THE PLUG BEFORE MAKING ANY ADJUSTMENTS OR REPAIRS.
TO ADJUST SKID HEIGHT
This snow thrower is equipped with two height adjust- ment skids, located on the outside of the auger housing (See III.20). These skids elevate the front of the snow thrower.
For normal hard surfaces, such as a paved driveway or walk, adjust the skids as follows:
●Check both tires for equal inflation. Correct tire pressure is 14 to 17 pounds. Do not exceed sidewall maximum pressure on tire.
●Place the extra shear bolts supplied (found in parts bag) under each end of the scraper bar near but not under the skid.
●Loosen the skid mounting nuts (See III.20), and adjust the skids up to bring the front of the snow thrower down.
●Set the skid on the other side at the same height.
NOTE: For rocky or uneven surfaces, raise the front of the snow thrower by moving the skids down. This will help prevent rocks and other debris from being picked up and thrown by the auger.
TO ADJUST SCRAPER BAR
After considerable use, the metal scraper bar will have a definite wear pattern. The scraper bar in conjunction with the skids should always be adjusted to allow 1/8" between the scraper bar and the sidewalk or area to be cleaned.
●Position the snow thrower on a level surface.
●Make sure both tires are equally inflated. Proper tire pressure is 14 to 17 PSI. See side of tire for maxi- mum inflation. Do not exceed sidewall maximum pressure on tire.
●Loosen the carriage bolts and nuts securing the scraper bar to the auger housing.
●Adjust the scraper bar to the proper position.
●Tighten the carriage bolts and nuts, making 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 carriage bolts and nuts and install a new scraper bar.
BE CERTAIN TO MAINTAIN PROPER GROUND CLEARANCE FOR YOUR PAR- TICULAR AREA TO BE CLEARED. OB- JECTS SUCH AS GRAVEL, ROCKS OR OTHER DEBRIS, IF STRUCK BY THE IMPELLER, MAY BE THROWN WITH SUF- FICIENT 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 between the center and top of the hole in the clutch lever and there is no droop in the cable (See III.21).
If adjustment is necessary:
●Remove gas from gas tank. Stand blower on end.
●Disconnect the “Z” Fitting from drive lever.
●Pull spring cover up to expose spring. Push the cable through the spring (See III.22) to expose the threaded portion of the cable.
●Hold the square end of the threaded portion with pliers and adjust the locknut in until the excess slack is removed (See III 22 INSET).
●Pull the cable back through the spring and connect the cable. Do the same for the other lever cable.
NOTE: Whenever the traction drive or auger belts are adjusted or replaced, the cables will need to be adjusted.
TO ADJUST BELTS
Belts stretch during normal use. If you need to adjust the belts due to wear or stretch, proceed as follows:
AUGER DRIVE BELT (See III.24)
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 damaged. If it is damaged, replace it. (See To Replace Belts paragraph in this section). If the auger drive belt is loose, adjust as follows:
●Disconnect the spark plug wire.
●Remove the belt cover (See III.25).
●Loosen the nut on the auger idler pulley (See III.23) and move the pulley toward the belt about 1/8".
●Tighten the nut.
