Safe Operation Practices for Snow Throwers
As Recommended By: American National Standards Institute.
IMPORTANT: Safety standards require operator
presence controls to minimize the risk of injury.
Your snow thrower is equipped with such controls. Do not attempt to defeat the function of the
operator presence control under any circumstances.
7. Never attempt to make any adjustments
while the engine (motor) is running (except
when specifically recommended by manufacturer).
Training
9. Always wear safety glasses or eye shields
during operation or while performing an adjustment or repair to protect eyes from foreign
objects that may be thrown from the snow
thrower.
1. Read the operating and service instruction
manual carefully. Be thoroughly familiar with
the controls and the proper use of the equipment. Know how to stop the unit and disengage the controls quickly.
2. Never allow children to operate the equipment. Never allow adults to operate the
equipment without proper instruction.
3. Keep the area of operation clear of all persons, particularly small children and pets.
8. Let engine (motor) and snow thrower adjust
to outdoor temperatures before starting to
clear snow.
Operation
1. Do not operate this machine if you are taking
drugs or other medication which can cause
drowsiness or affect your ability to operate
this machine.
4. Exercise caution to avoid slipping or falling
especially when operating in reverse.
2. Do not use this machine if you are mentally
or physically unable to operate this machine
safely.
Preparation
3. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.

move the choke control (14) to the off position.
14. (Electric Start) First disconnect the power
cord from the three–hole receptacle. Then,
disconnect the power cord from the switch
box (11).
NOTE: In temperatures below 0F, allow
the engine to warm up for several minutes
before blowing snow.
15. When throwing snow, always run the engine
with the throttle control (13) in the fast position.
WARNING: Never run the engine
indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and
deadly gas. Keep hands, feet, hair and
loose clothing away from any moving parts
located on the engine or the snow thrower.
The temperature of muffler and nearby
areas may exceed 150°F. Avoid these
areas.
How To Start A Warm Engine (Figure 2)
If an engine has been running and is still warm,
leave the choke control (14) in the off position
and do not push the primer button (9). If the
engine fails to start, follow the instructions “How
To Start A Cold Engine”.
NOTE: Do not use the primer button (9) to
start a warm engine.
How To Start An Engine With A Frozen Electric
Starter (Figure 2)
If the electric starter is frozen and will not turn
the engine, follow the instructions below.
1. Pull out the recoil starter handle (12) as far
as possible.
2. Quickly release the recoil starter handle
(12). Allow the recoil starter handle (12) to
snap back against the recoil starter.
If the engine still fails to start, repeat the two previous steps until the engine starts. Then, continue with the directions “How To Start A Cold
Engine”.
To help prevent the possible freeze–up of the
recoil starter and of the engine controls, proceed
as follows after each snow removal job.
1. With the engine running, quickly pull the recoil starter handle (12) three or four times
with a continuous full arm stroke. This will
produce a loud clattering sound that is not
harmful to the engine or starter.
ENGLISH
2. Stop the engine. Wipe all snow and moisture
from the carburetor cover, control levers and
cables. Also move the throttle control (13),
choke control (14), and recoil starter handle (12) several times.
How To Remove Snow or Debris From
The Auger Housing (Figure 2)
WARNING: Do not attempt to remove snow or debris that may become lodged in auger housing
without taking the following precautions.
1. Release the auger drive lever (5).
2. Move the throttle control (13) to the stop
position.
3. Remove (do not turn) the ignition key (8).
4. Disconnect the spark plug wire.
F–001043J
5. Do not place your hands in the auger housing (4) or the discharge chute (3). Use a
pry bar to remove any snow or debris.
Snow Throwing Tips
1. For maximum snow thrower efficiency,
change the ground speed, NEVER change
the engine speed. The engine is designed to
deliver maximum performance at full throttle
and must be run in the fast position at all
times. In deep, freezing, or wet snow, reduce
forward speed. If the wheels slip, also reduce
forward speed.
2. Most efficient snow throwing is accomplished
when the snow is removed immediately after
if falls.
3. For complete snow removal, slightly overlap
each previous path.
4. Whenever possible, discharge the snow
down wind.
13
5. For normal usage, set the skids so that the
scraper bar is 1/8” 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 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.
