Operation
ENGINE SPEED
For overall best performance, run the snowthrower at full engine operating speed. Use the engine Throttle Lever (E, Figure 6) to set the engine speed. Slide the Throttle Lever UP to increase engine speed, and DOWN to reduce speed.
GROUND SPEED SELECTOR
Use the Speed Selector (A, Figure 7) to control the drive speed of the snowthrower. There are five forward speeds and two reverse speeds.
Use the lower speeds to blow deep or wet snow. Use the higher speeds to blow light snow or to drive the snow- thrower without blowing snow.
To change speeds, release both control levers (B, Figure 7), then move the Speed Selector to the desired setting. Fully depress the control levers to resume.
DEFLECTOR
The distance of the discharged snow is mainly controlled by the position of the deflector. (Engine speed also affects distance of discharge.) The more the deflector is tilted UP, the farther snow will be thrown.
Models with Chute Deflector Knob
1.Loosen the deflector knob, tilt the deflector UP or DOWN.
2.Retighten the knob when desired angle has been chosen.
Models with Remote Deflector Control
1.Turn the Remote Deflector Control counterclockwise to UNLOCK, and the spring will pull the deflector to the maximum throwing position. Pull the knob UP to decrease the throwing distance.
2.Turn the Remote Deflector Control knob clockwise to LOCK in place when the desired angle has been cho- sen.
SCRAPER BAR & SKID SHOES
On smooth surfaces such as concrete or asphalt, the scraper bar should scrape the surface. On surfaces such as gravel, the scraper bar should be high enough so that it will not pick up gravel or debris.
The height of the scraper bar is controlled by raising or lowering the Skid Shoes (See Figure 10).
1.To raise the scraper bar height, rest the scraper bar on a strip of wood equal in thickness to the desired height.
2.Make sure the scraper bar is parallel to the ground surface.
3.Loosen the skid shoe nuts and let the skid shoes drop to the surface.

4.Tighten the nuts, making sure the Skid Shoes are adjusted equally and are parallel to the surface.
5.To lower the height of the scraper bar, raise the Skid Shoes.
6.If the scraper bar becomes worn, it can be replaced by removing the hardware attaching it to the snowthrower.
