Scraper Blade
The scraper blade allows the back of the
housing to keep better contact with the
surface being cleared. It also prevents
damage to the housing from normal use.
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 18 for
recommended settings.
FILLING FUEL TANK
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.
To add fuel to fuel tank:
1. ALWAYS place unit in open or well-
ventilated area.
2. Stop engine and allow to cool.
3. Clean Fuel Cap and surrounding area to
prevent dirt from entering Fuel Tank.
4. Remove Cap.
IMPORTANT: Refer to Engine Manual for
proper fuel type and tank capacity.
5. Replace Fuel Cap and tighten.
6. ALWAYS clean up any spilled fuel.
WARNING: AVOID INJURY. Read
and understand the entire Safety
section before proceeding.
