To operate the product
CAUTION: Do not operate without snow or
water to lubricate the auger blades. Incorrect
use can cause high temperatures in the
auger blades, especially if the product is
new. This can cause damage to the auger
blades and scraper bar.
CAUTION: Do not partially engage drive or
auger levers for an extended period of time;
this can lead to premature wear or burning
of the belts.
Note: When both the drive engagement and auger
engagement are engaged, the drive engagement will
lock the auger engagement in position. Use the right
hand to control the snow discharge chute.
Note: Do not change the speed when the drive lever is
engaged. This can cause damage to the transmission.
1. To engage the auger blades, push the auger
engagement (A) to the handle to engage the auger
and throw snow. (Fig. 61)
2. Raise the drive speed control lever (B) from the
middle position to make the product move forward
when the drive engagement (C) is engaged. Do not

To adjust the skid plates
The skid plates prevent damage to the bottom of the
snow thrower. Adjust the skid plates (A) when the
locknut (B) is loose, or the skid plate is not at the correct
distance from the ground. No adjustment is necessary
for standard installation.
1. Loosen the locknut (B) with a 13 mm (½ in.) open
wrench.
2. Move the skid plates (A) up or down.
a) On flat surfaces set the distance between the
scraper bar and the ground to 5-6 mm (0.2-0.25
in).
b) On rough surfaces set the skid plates (A) in a
position where the scraper bar is above the top
of the ground.
WARNING: Make sure that gravel
and stones do not go into the
product. Objects that eject at high
speed can cause injury.
