SAFETY CS-450P
Automatic Chain Brake
Kickback produced from the tip of the guide bar will trip the
automatic chain brake. To make sure that the automatic chain
brake operates properly, follow these steps:
1. Stop the engine.
2. Hold the saw with the guide bar approximately 35 cm (14
in.) above a wooden surface. Right hand should hold the
rear handle, and left hand should hold the front handle.
3. Release the front handle and drop the end of the guide bar
against the wooden surface.
4. The impact should lock the chain brake.
When checking the operation of the automatic chain brake, use
a soft surface substance like wood to absorb the impact so the
chain is not damaged.
Other Safety Precautions
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 and protective gloves. Wear eye, hearing, and head protection
devices.
4. Use caution when handling fuel. Move the chain saw at least 3 m (10 feet) from the fueling point before
starting the engine.
5. Do not allow other persons to be near the chain saw when starting 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 spring-back so that you will not be struck when the
tension in the wood fibers is released.
