ADJUST SKID HEIGHT
This snowthrower is equipped with two height adjust skids, secured to the
outside of the auger housing. These elevate the front of the snowthrower.
When removing snow from a hard surface area such as a paved driveway
or walk, adjust the skids up to bring the front of the snowthrower down.
When removing snow from rock or uneven construction, raise the front of
the snowthrower by moving the skids down. This will help to prevent rocks
and other debris from being picked up and thrown by the augers.
