BASIC CUTTING PROCEDURE

Practice cutting a few small logs using the following

technique to get the “feel” of using the saw before

you begin a major sawing operation.

 Take the proper stance in front of the wood with

the saw off.

 Squeeze the switch trigger and let the chain

accelerate to full speed before entering the cut.

 Begin cutting with the saw against the log.

 Keep the unit running the entire time you are

cutting, maintain a steady speed.

 Allow the chain to cut for you; exert only light

downward pressure. If you force the cut,

damage to the bar, chain, or unit can result.

 Release the switch trigger as soon as the cut

is completed, allowing the chain to stop. If you

run the saw without a cutting load, unnecessary

wear can occur to the chain, bar, and unit.

 Do not put pressure on the saw at the end of

cut.

WORK AREA PRECAUTIONS

See Figure 13.

 Cut only wood or materials made from wood,

no sheet metal, no plastics, no masonry, no

non-wood building materials.

 Never allow children to operate the saw. Allow

no person to use this chain saw who has

not read this Operator’s Manual or received

adequate instructions for the safe and proper

use of this chain saw.

 When felling a tree, keep everyone - helpers,

bystanders, children, and animals - a safe

distance from the cutting area. During felling

operations, the safe distance should be a

least twice the height of the largest trees in the

felling area. During bucking opetations, keep a

minimum distance of 15 feet between workers.

Trees should not be felled in a manner that

would endanger any person, strike any utility

line or cause any property damage. If the tree

does make contact with any utility line, the utility

company should be notified immediately.

 Always cut with both feet on solid ground to

prevent being pulled off balance.
