• To Engage Drive Pull the starter handle with a firm, rapid stroke. IMPORTANT: Do not release the handle and allow it to • snap back. Keep a firm hold on the starter handle and allow it to slowly recoil. • As the engine warms, slowly rotate the choke control to the OFF position. If the engine falters, quickly rotate the choke control back to the FULL position and then slowly into the OFF position again.
• • • • To readjust the control cable, loosen the hex jam nut on the auger control cable “Z” fitting. Rotate the coupling end of the cable counterclockwise to provide more slack. Retighten the hex jam nut. See Figure 1. Repeat Auger Control Test to verify proper adjustment has been achieved. • • Remove the clean-out tool from the clip which secures it to the rear of the auger housing.
SECTION 5: MAKING ADJUSTMENTS WARNING: Never attempt to make any adjustments while the engine is running, except where specified in operator’s manual. 1 Shift Rod Adjustment If the full range of speeds (forward and reverse) cannot be achieved, refer to the figures to the right and adjust the shift rod as follows: 1. Place the shift lever in the fastest forward speed position and remove the hairpin clip which secures the ferrule to the shift lever. 2. Rotate the shift arm clockwise as far as it will go. 3.
Drive Control When the drive control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight. Check the adjustment of the drive control as follows: 1. With the drive control released, push the snow thrower gently forward. The unit should roll freely. 2. Engage the drive control and gently attempt to push the snow thrower forward. The wheels should not turn. The unit should not roll freely. 3.
SECTION 6: MAINTAINING AND SERVICING YOUR SNOW THROWER WARNING: Before lubricating, repairing, or Auger Shaft inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop. • At least once a season, remove the shear pins on auger shaft. Spray lubricant inside shaft, around the spacers. Also lubricate the flange bearings found at either end of the shaft. See Figure 6.
