FORCE OF GRAVITY & “FOLLOW THROUGH” – Gravity is always present

and you must be prepared for it when you are operating a chain saw. During the

cutting operation, the weight of the chain saw is supported by the material being

cut. When the saw completes the cut, the saw is no longer supported, and the

operator must control both the weight and the downward momentum of the saw.

Never reach too far out with the saw. If you reach too far out with the saw, you

may be unable to control it. Maintain a proper grip, a balanced stance, and good

footing. Never cut when you are off balance – the sudden burden of supporting

the weight of the saw could cause you to fall or lose control of the saw. Make no

cuts above chest height where control may be more difficult.

IMPORTANT: When you’re about to complete a cut on an elevated tree branch or

limb, be ready to release the throttle and support the chain saw so that the guide

bar and moving chain will not “follow through” and cut into your legs, feet, or body

after the guide bar breaks into the clear.

SKATING - This condition occurs when the saw chain does not dig in properly

when starting a cut, and does not start a defined groove as it attempts to

penetrate the wood. The guide bar then begins “hopping” or skidding side-to-side

along the surface. When this occurs, you do not have full control of the chain

saw, and the bar nose could strike something and cause a kickback. If you are

holding the chain saw with one hand and a branch with the other, the chain saw

could skate laterally into your hand holding the branch. To prevent or reduce

skating, always hold the chain saw with two hands, and make sure the saw chain

has established a groove for cutting. For gasoline-powered units, throttling down

the chain speed may help the chain get grooved, but once the chain is grooved,
throttle up the chain speed to complete the cut

.
