BEFORE EACH OPERATION

Your safety is your responsibility. A little time spent in preparation will 
significantly reduce your risk of injury.
Read and understand this manual. Know what the controls do and 
how to operate them.
Familiarize yourself with the snow blower and its operation before you 
begin using it. Know how to quickly shut off the snow blower in case of 
an emergency.

Check Your Snow Blower

For your safety, and to maximize the service life of your snow blower, 
it is very important to take a few moments before you operate the 
snow blower to check its condition. Be sure to take care of any 
problem you find, or have your servicing dealer correct it, before you 
operate the snow blower.

• Make sure the snow blower is on a level surface.
• Look around and underneath the snow blower for signs of oil or 

gasoline leaks.

• Look for signs of damage.
• Check each control for proper operation.
• Check the auger paddles for wear. Replace as necessary (

page 13

).

• Check the scraper blade for wear. Replace as necessary (

page 13

).

• Check that all nuts, bolts, and screws are tightened.
• Check the oil level (

page 5

).

• Check the fuel level (

page 6

). Starting with a full tank will help to 

eliminate or reduce operating interruptions for refueling.

Check Your Working Area

For your safety and the safety of others, always inspect the area 
before operating the snow blower.

Anything that can be picked up by the auger blades and thrown is a 
potential hazard to you and others. Look for things like stones, sticks, 
nails, and wire, and remove them from the area.

People and animals near the area can move into your path or into a 
position where they could be struck by thrown objects. Clear the area 
of pets and people, especially children. Their safety is your 
responsibility.

Check the condition of the snow. Adjust your snow blowers ground 
speed and swath accordingly.

Check the Oil Level

1. With the snow blower on a level surface, remove the oil filler 

cap/dipstick and wipe it clean.

2. Insert and remove the 

dipstick 

without 

screwing it into the 
filler neck

. Make sure oil 

is showing on the 
dipstick.

3. If the oil level is low, add 

enough recommended oil 
to bring the level to the 
top of the oil filler 
opening.
Do not overfill. For oil 
recommendations, see 

page 12

.

NOTICE

Running the engine with 
a low oil level can cause 
engine damage.

4. Screw in the filler 

cap/dipstick securely.

Check the Scraper Blade

Check the scraper blade for excessive wear. 

Refer to “Scraper Blade” on 

page 13

 for complete inspection and 

adjustment procedures.

 WARNING

Improperly maintaining this snow blower, or failing to correct a 

problem before operation, could cause a significant 

malfunction.
Some malfunctions can seriously hurt or kill you.
Always perform a pre-operation inspection before each 

operation, and correct any problem.
