Safety Checks
Check Snowthrower Controls
1.Check the skid shoes to make sure they are set at the desired height. Adjust if necessary.
2.Check the traction drive control (B, Figure 2). Snowthrower motion should stop when the control is released.
3.Check the auger control (C). Auger movement should stop when the control is released.
4.Check the manual chute direction control (D) for prop- er operation. The discharge chute should rotate freely in both directions.
5.Check the deflector for proper operation. The deflector should pivot freely up and down when the chute deflector knob (E) is loosened.
6.Check the speed selector (A) for smooth operation. The control must move freely into each speed posi- tion gate and remain in position when released.
If controls do not function properly, perform the appropriate adjustment as shown in the Adjustment Section.
7.The auger is secured to the shaft by shear pins, which will break if the auger strikes an object. Extra shear pins are provided. Keep these pins in the com- partment on the belt cover. Lubricate the auger shaft.
