• Tohelppreventsnowfromstickingtothesnowthrower,
allow the snow thrower to reach outdoor temperature
before using it. A light coat of wax may also be applied

WARNING: To avoid serious injury, operate your tractor up and
down the face of slopes, never across the face. Do not operate
on slopes greater than 10 degrees. Make turns gradually to
prevent tipping or loss of control. Exercise extreme caution
when changing direction on slopes. Braking may be affected by
tractor attachment. Reduce speed on slopes.
1. Fold this page along dotted line indicated above.
2. Hold page before you so that its left edge is vertically parallel to a tree
trunk or other upright structure.
3. Sight across the fold in the direction of hill slope you want to measure.
4. Compare the angle of the fold with the slope of the hill.
ONLY RIDE UP AND DOWN HILL,
NOT ACROSS HILL
