It helps to hold a flashlight 
under the snow blower 
between the shroud and 
engine, shining towards 
the carburetor bowl.

3. Use a long, flat-tip 

screwdriver to loosen 
without removing the 
drain screw until fuel 
starts to drain.

Drain until the fuel tank is 
empty, and then tighten 
the drain screw.

Lubrication

Apply a small amount of grease to the following parts for lubrication 
and rust prevention.

Cleaning

Rinse the auger housing and wheels with a garden hose. Wipe the 
rest of the snow blower with a moist rag. 

Storage Location

If your snow blower will be stored with gasoline in the fuel tank and 
carburetor, it is important to reduce the hazard of gasoline vapor 
ignition. Select a well-ventilated dry storage area away from any 
appliance that operates with a flame, such as a furnace, water heater, 
or clothes dryer. Also avoid any area with a spark-producing electric 
motor, or where power tools are operated.

Make sure the fuel valve is in the OFF position to reduce the 
possibility of fuel leakage.

Place the snow blower on a level surface. Tilting can cause fuel or oil 
leakage.

With the engine and exhaust system cool, cover the snow blower to 
keep out dust. A hot engine and exhaust system can ignite or melt 
some materials. Do not use sheet plastic as a dust cover. A 
nonporous cover will trap moisture around the snow blower, 
promoting rust and corrosion.

Removing From Storage

Check your snow blower as described in 

BEFORE OPERATION

 

(

page 5

).

If the cylinder was coated with oil during storage preparation, the 
engine may smoke briefly at startup.

Electric Starter Will Not Operate

(AS type)

Starter Operates But the Engine Will 
Not Start 

Engine Runs But the Auger Does Not 
Operate

DRAIN SCREW

DRAIN PAN

DRAIN 
TUBE

CHUTE TENSION 
BOLTS

(AM type only)

Possible cause

Correction

No electric power from 
the outlet.

Try a known good electrical outlet or 
start the engine by using the recoil 
starter.

Defective power cord.

Try another power cord or start the 
engine using the recoil starter.

Possible cause

Correction

Engine switch is OFF.

Turn the engine switch ON.

Fuel valve is OFF.

Turn the fuel valve ON (

page 7

).

Stale or old fuel.

Be sure the tank has fresh fuel.
Drain the carburetor (

page 14

).

Spark plug cap is off.

Make sure the cap is connected.

Improper gap or 
deposits in the spark 
plug gap.

Verify the spark plug is free of 
deposits and has the proper gap 
(

page 12

).

Possible cause

Correction

Auger paddles are worn 
out.

Replace the auger paddles.

Auger clutch lever is not 
engaged.

Engage the auger clutch lever by 
pulling it toward the handlebar.

Clutch lever free play is 
excessive.

Adjust the free play (

page 12

).

Auger not engaging 
because the drive belt is 
worn, broken, or not on 
the pulleys.

See your servicing Honda snow
