Warm engines will cause condensation in cold
weather. To 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 or
a pry bar to remove snow or debris.
(Figure 21) On some models, a clean−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
(5).
2. Pull out the safety key (8).
3. Do not place your hands in the auger
housing (4) or the discharge chute (3).
4. (Figure 21) 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.
