A Speed Selector B Drive Control C Auger Control D Chute Direction Control Operation ENGINE SPEED For overall best performance run the snowthrower at full engine operating speed Use the engine Throttle Lever See Figure 8 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 first release the traction Drive Control lever B Figure 7 then move the Speed Selector to the desired speed setting Fully press the traction Drive Control lever to resume operation DEFLECTOR The distance of the discharged snow is mainly controlled by the position of the deflector Figure 9 Engine speed also affects distance of discharge The more the deflector is tilted UP the farther snow will be thrown Loosen the deflector knob tilt the deflector UP or DOWN and then retighten the knob when the desired angle has been chosen SCRAPER BAR amp 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
4. 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 Make sure the scraper bar is parallel to the ground surface Loosen the skid shoe nuts and let the skid shoes drop to the surface Tighten the nuts making sure the Skid Shoes are adjusted equally and are parallel to the surface To lower the height of the scraper bar raise the Skid Shoes If the scraper bar becomes worn it can be replaced by removing the hardware attaching it to the snowthrower 10 Throttle Lever Figure 8 Engine Speed Selection Chute Deflector Knob Chute Deflector Figure 9 Chute Deflector Adjustment hi A a KC cal Skid Shoe ar Nuts Skid Shoe Figure 10 Skid Shoe Adjustment FREE WHEELING AND TRACTION DRIVE LOCK For easy turning when pushing the snowthrower you can disengage the traction drive at one or both wheels by using the Traction Lock Pins See Figures 11 amp 12 1 Turn the unit off remove the Engine Key and discon nect the spark plug wire 2 To DISENGAGE the traction drive lock insert the Traction Lock Pin through the outer hole in the axle See Figure 8 3 To ENGAGE the traction drive lock insert the pin through the hub and axle See Figure 9 If the hole in the hub is not al
