SWhen cutting with the saw, the chain brake must be disengaged.

Disengaged

Engaged

Braking function control CAUTION: The chain brake must be

checked several times daily. The engine must be running when performing this proce- dure. This is the only instance when the saw should be placed on the ground with the en- gine running.

Place the saw on firm ground. Hold the han- dles with both hands and apply full throttle. Activate the chain brake by turning your left wrist against the hand guard without releas- ing your grip around the front handle. The chain should stop immediately.

WARNING: When performing the following procedure, the engine must be turned off.

Hold the chain saw approximately 14″ (35 cm) above a stump or other wooden surface. Release your grip on the front handle and use the weight of the saw to let the top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.

CUTTING METHODS

IMPORTANT POINTS

SCheck chain tension before first use and after 1 minute of operation. See CHAIN

TENSION in the ASSEMBLY section.

SCut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc.

SStop the saw if the chain strikes a foreign object. Inspect the saw and repair parts as necessary.

SKeep the chain out of dirt and sand. Even a small amount of dirt will quickly dull a chain

and increase the possibility of kickback.

SPractice cutting a few small logs using the following techniques to get the “feel” of us- ing your saw before you begin a major sawing operation.

S Squeeze the throttle trigger and allow the engine to reach full speed before cut- ting.

S Begin cutting with the saw frame against the log.

S Keep the engine at full speed the entire time you are cutting.

S Allow the chain to cut for you. Exert only light downward pressure.

S Release the throttle trigger as soon as the cut is completed, allowing the engine to idle. If you run the saw at full throttle without a cutting load, unnecessary wear can occur to the chain, bar, and en- gine. It is recommended that the en- gine not be operated for longer than 30 seconds at full throttle.

S To avoid losing control when cut is com- plete, do not put pressure on saw at end

of cut.

S Stop the engine before setting the saw down.

TREE FELLING TECHNIQUES

WARNING: Check for broken or dead branches which can fall while cutting causing serious injury. Do not cut near build- ings or electrical wires if you do not know the direction of tree fall, nor cut at night since you will not be able to see well, nor during bad weather such as rain, snow, or strong winds,

etc. If the tree makes contact with any utility line, the utility company should be notified immediately.

SCarefully plan your sawing operation in ad-

vance.

SClear the work area. You need a clear area all around the tree so you can have secure

footing.

SThe chain saw operator should keep on the uphill side of the terrain as the tree is

likely to roll or slide downhill after it is felled. S Study the natural conditions that can cause the tree to fall in a particular direc-

tion.

Natural conditions that can cause a tree to fall in a particular direction include:

SThe wind direction and speed.

S The lean of the tree. The lean of a tree might not be apparent due to uneven or sloping terrain. Use a plumb or level to de- termine the direction of tree lean.

SWeight and branches on one side. S Surrounding trees and obstacles.

Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator. Check for broken or dead branches which can fall on you while cutting.

Make sure there is enough room for the tree to fall. Maintain a distance of 2-1/2tree lengths from the nearest person or other ob- jects. Engine noise can drown out a warning call.

Remove dirt, stones, loose bark, nails, sta- ples, and wire from the tree where cuts are to be made.

Plan a clear retreat path to the rear and diag- onal to the line of fall.
