GENERAL SAFETY RULES
GB
WARNING!
When using gas tools, basic safety precautions, including the following, should always be followed to
reduce the risk of serious personal injury and/or damage to the unit.
Read all these instructions before operating this product and save these instructions.
1. DO NOT operate a chain saw with one hand! Serious
injury to the operator, helpers, bystanders, or any
combination of these persons may result from one-
handed operation. A chain saw is intended for two-
handed use.
2. DO NOT operate a chain saw when you are fatigued.
3. Use safety footwear, snug-fitting clothing, protective
gloves, and eye, hearing and head protection
devices.
4. Use caution when handling fuel. Move the chain saw
at least 10 feet (3m) from the fueling point before
starting the engine.
5. DO NOT allow other persons to be near when start-
ing or cutting with the chain saw. Keep bystanders
and animals out of the work area.
6. DO NOT start cutting until you have a clear work
area, secure footing, and a planned retreat path from
the falling tree.
7. Keep all parts of your body away from the saw chain
when the engine is running.
8. Before you start the engine, make sure that the saw
chain is not contacting anything.
9. Carry the chain saw with the engine stopped, the
guide bar and saw chain to the rear, and the muffler
away from your body.
10. DO NOT operate a chain saw that is damaged,
improperly adjusted, or not completely and securely
assembled. Be sure that the saw chain stops moving
when the throttle control trigger is released.
11. Shut off the engine before setting the chain saw
down.
12. Use extreme caution when cutting small size brush
and saplings because slender material may catch the
saw chain and be whipped toward you or pull you off
balance.
13. When cutting a limb that is under tension, be alert for
springback so that you will not be struck when the
tension in the wood fibers is released.
14. Keep the handles dry, clean, and free of oil or fuel
mixture.
15. Operate the chain saw only in well-ventilated areas.
16. DO NOT operate a chain saw in a tree unless you
have been specifically trained to do so.
17. All chain saw service, other than the items listed in
the user manual safety and maintenance instructions,
should be performed by competent chain saw service
personnel.
18. When transporting your chain saw, use the appropri-
ate guide bar scabbard (when supplied).
19. DO NOT operate your chain saw near or around
flammable liquids or gases whether in or out of doors.
An explosion and/or fire may result.
20. Do not tank fuel, oil or lubrication when the engine of
chain saw is running.
21. USE THE RIGHT TOOL: Cut wood only. Do not use
the chain saw for purposes for which it was not
intended. For example, do not use the chain saw for
cutting plastic, masonry, or nonbuilding materials.
NOTE:
This appendix is intended primarily for the con-
sumer or occasional user. These models are intended for
infrequent use by homeowners, cottagers, and campers,
and for such general applications as clearing, pruning,
cutting firewood, etc. They are not intended for prolonged
use. If the intended use involves prolonged periods of
operation, this may cause circulatory problems in the
user’s hands due to vibration. It may be appropriate to use
a saw having an anti-vibration feature such as the models
covered in this manual with the suffix Anti-Vibration.
Kickback may occur when the nose or tip of the guide bar
touches an object, or when the wood closes in and pinch-
es the saw chain in the cut. If the bar tip contacts, it may
cause a lightning-fast reverse reaction, kicking the guide
bar up and back towards the operator. Pinching the saw
chain along the top of the guide bar may push the guide
bar rapidly back towards the operator. Either of these
reactions may cause you to lose control of the saw, which
could result in serious personal injury. Do not rely exclu-
sively upon the safety devices built into your saw. As a
chain saw user, you should take several steps to keep
your cutting jobs free from accident or injury.
1. With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
2. Keep a good firm grip on the saw with both hands,
the right hand on the rear handle, and the left hand
on the front handle, when the engine is running. Use
a firm grip with thumbs and fingers encircling the
chain saw handles. A firm grip will help you reduce
kickback and maintain control of the saw. Don’t let
go.
3. Make sure that the area in which you are cutting is
free from obstructions. Do not let the nose of the
guide bar contact a log, branch, or any other obstruc-
tion which could be hit while you are operating the
saw.
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
6. Follow manufacturer’s sharpening and maintenance
instructions for the saw chain.
7. Only use replacement bars and chains specified by
the manufacturer or the equivalent.
