Warm engines will cause condensation in cold
weather. T

o prevent possible freeze�up of recoil

starter and engine controls, proceed as follows
after each snow removal job.
1. Run the snow thrower a few minutes after

throwing snow to prevent freeze

up of the

auger/impeller.

2. With engine off, allow engine to cool for

several minutes.

3. Pull starter rope very slowly until resistance

is felt, then stop. Allow the starter rope to
recoil. Repeat three times.

4. With the engine not running, wipe all snow

and moisture from the carburetor cover in
area of controls and levers. Also, move the
choke control and starter handle several
times.

How To Remove Snow or Debris From

The Auger Housing

WARNING: Do not attempt to
remove snow or debris that may
become lodged in auger housing

with your hands. Use the clean�out tool o

r

a pry bar to remove snow or debris.

(Figure 21) 

On some models, a 

clea

n�

out tool

(1)

 is attached to the top of the auger housing.

Use the 

clean�out

 tool (1)

 to remove snow

from the auger housing.
1.

(Figure 1) 

Release the 

auger drive lever

.

2. Pull out the 

safety key (8)

.

3. Do not place your hands in the 

auger

housing (4)

 or the 

discharge chute (3)

.

Use the 

clean�out tool (1

)

 or a

pry bar to remove any snow or debris.

Snow Throwing Tips

1. For maximum snow thrower efficiency in

removing snow, adjust ground speed. Go
slower in deep, freezing or wet snow. If the
wheels slips, reduce forward speed.

2. Most efficient snow throwing is accomplished

when the snow is removed immediately after
if falls.

CAUTION: Do not overload the machine
capacity by attempting to clear snow at
too fast a rate.

3. For complete snow removal, slightly overlap

each previous path.

4. Whenever possible, discharge the snow

down wind.

5. For normal usage, set the skids so that the

scraper bar is 1/8” (3 mm) above the skids.

For extremely hard�packed snow surfaces,

adjust the skids upward so that the scraper
bar touches the ground.

6. Rocks and gravel must not be picked up and

thrown by the machine. On gravel or crushed

rock surfaces, set the skids at 1�1/4 inch

(32 mm) below the scraper bar. See “How To
Adjust The Height Of The Skids” in the
Maintenance section.

7. After each snow throwing job, allow the

engine to idle for a few minutes. The snow
and accumulated ice will melt off the engine.

8. Clean the snow thrower after each use.
9. Remove ice, snow and debris from the entire

snow thrower. Flush with water to remove all
salt or other chemicals. Wipe snow thrower
dry.

manual.
Some adjustments must be made periodically to
properly maintain the snow thrower.

After Each Use

Check for any loose or damaged parts.

Tighten any loose fasteners.

Check and maintain the auger.

Check controls to make sure they are
functioning properly.

If any parts are worn or damaged, replace
