Clean-Out Tool
Never use your hands to clear a clogged chute assembly. Shut off engine
and remain behind handles until all moving parts have stopped before
using the clean-out tool to clear the chute assembly.
The chute clean-out tool is conveniently fastened to the rear of the auger housing
with a mounting clip. Should snow and ice become lodged in the chute assembly
during operation, proceed as follows to safely clean the chute assembly and chute
opening:
1. Release both the Auger Control and the Drive Control.
2. Stop the engine by removing the ignition key.
3. Remove the clean-out tool from the clip which secures it to the rear of the
auger housing.
4. Use the shovel-shaped end of the clean-out tool to dislodge and scoop any
snow and ice which has formed in and near the chute assembly.
5. Refasten the clean-out tool to the mounting clip on the rear of the auger
housing, reinsert the ignition key and start the snow thrower's engine.
6. While standing in the operator's position (behind the snow thrower), engage
the auger control for a few seconds to clear any remaining snow and ice from
the chute assembly.
Before Starting Engine
Read, understand, and follow all instructions and warnings on the
machine and in this manual before operating.
Oil
The unit was shipped with oil in the engine. Check oil level before each operation to
ensure adequate oil in the engine.
NOTE: Be sure to check the engine on a level surface with the engine stopped.
1. Remove the oil filler cap/dipstick and wipe the dipstick clean.
2. Insert the cap/dipstick into the oil filler neck, but do NOT screw it in.
3. Remove the oil filler cap/dipstick. If the level is low, slowly add oil (5W-30,
with a minimum classification of SF/SG) until oil level registers between high
(H) and low (L).
NOTE: Do not overfill. Overfilling with oil may result in engine smoking, hard
starting or spark plug fouling.
4. Replace and tighten cap/dipstick firmly before starting engine.
Gasoline
Use automotive gasoline (unleaded or low leaded to minimize combustion chamber
deposits) with a minimum of 87 octane. Gasoline with up to 10% ethanol or 15%
MTBE (Methyl Tertiary Butyl Ether) can be used. Never use an oil/gasoline mixture
or dirty gasoline. Avoid getting dirt, dust, or water in the fuel tank. DO NOT use E85
gasoline.
• Refuel in a well-ventilated area with the engine stopped. Do not smoke or
allow flames or sparks in the area where the engine is refueled or where
gasoline is stored.
OPERATION
WARNING
WARNING
• Do not overfill the fuel tank. After refueling, make sure the tank cap is closed
properly and securely.
• Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make sure the area is dry before starting the
engine.
• Avoid repeated or prolonged contact with skin or breathing of vapor.
Use extreme care when handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never fuel the machine indoors or
while the engine is hot or running. Extinguish cigarettes, cigars, pipes and
other sources of ignition.
1. Clean around fuel fill before removing cap to fuel.
2. A fuel level indicator is located in the fuel tank. See Figure 10 inset. Be
careful not to overfill. Fill tank until fuel reaches the fuel level indicator to
allow space for fuel expansion.
Starting The Engine
Always keep hands and feet clear of moving parts. Do not use a pressurized
starting fluid. Vapors are flammable.
NOTE: Allow the engine to warm up for a few minutes after starting. The engine will
not develop full power until it reaches operating temperatures.
1. Make certain both the auger control and drive control are in the disengaged
(released) position.
2. Insert key into slot. Make sure it snaps into place. Do not attempt to turn the
key.
NOTE: The engine cannot start without the key fully inserted into the
ignition switch.
Electric Starter
The electric starter is equipped with a grounded three-wire plug, and is
designed to operate on 120 volt AC household current. It must be used
with a properly grounded three-prong receptacle at all times to avoid
the possibility of electric shock. Follow all instructions carefully prior to
operating the electric starter. DO NOT use electric starter in the rain.
Determine that your home's wiring is a three-wire grounded system. Ask a licensed
electrician if you are not certain.
If you have a grounded three-prong receptacle, proceed as follows. If you do not
have the proper house wiring, DO NOT use the electric starter under any conditions.
1. Plug an extension cord into the outlet located on the engine's surface. Plug
the other end of extension cord into a three-prong 120-volt, grounded, AC
outlet in a well-ventilated area.
The extension cord can be any length, but
125 volts, grounded and rated for outdoor use.
