Scraper Blade
The scraper blade allows better contact with
the surface being cleared. It also prevents
damage to the housing from normal usage.
IMPORTANT: DO NOT allow Scraper Blade
to wear too far or Auger/Impeller housing will
become damaged.
Skid Shoes
The skid shoes control the distance between
the scraper blade and the ground. Adjust skid
shoes equally to keep blade level with the
ground. Refer to Pre-Start on page 21 for
recommended settings.
Track Angle
(921023)
(Figure 22)
The track angle can be adjusted to position
the auger housing for level clearing, deep
cutting or transport.
Squeeze the handlebar trigger and press
down on the handlebars to move the auger
housing into an up position. Release the
trigger to hold the position.
Lift up on the handlebars and squeeze and
release the handlebar trigger to move the
auger housing into a down position.

GASOLINE
IMPORTANT: ALWAYS use gasoline that
meets the following guidelines:
• Clean, fresh gasoline.
• A minimum of 87 octane/87 AKI (91
RON). High altitude use may require a
different octane. Consult your engine
manual.
• Gasoline with up to 10% ethanol
(gasohol) or up to 10% MTBE (methyl
tertiary butyl ether) is acceptable.
• Use of any gasoline other than those
approved above will void the engine
warranty. If the pumps are not marked
for the content of alcohol or ethers,
check ethanol and MTBE levels with
the fuel supplier.
• Do not modify the fuel system to use
different fuels.
• Never mix oil and gasoline.
NOTE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
Fuel Stabilizer
Gasoline left in the fuel system for extended
periods without a stabilizer will deteriorate,
resulting in gum deposits in the system.
These deposits can damage the carburetor
and the fuel hoses, filter and tank. Prevent
deposits from forming in the fuel system
during storage by adding a quality fuel
stabilizer to the fuel. Follow the
recommended mix ratio found on the fuel
stabilizer container.
Fuel Shut-Off Valve
IMPORTANT: The fuel shut-off valve MUST
be in the closed position prior to transporting
the unit.
The fuel shut-off valve has two positions:
Open Position (1): Use this position to
run the unit.
Closed Position (2): Use this position to
service, transport, or store the unit.
