Difficult starting or flooded engine:
The engine may be flooded with too much

fuel if it has not started after 10 pulls.

Flooded engines can be cleared of excess

fuel by following the warm engine starting

procedure listed above. Insure the ignition

switch is in the

START

position.

Starting could require pulling the starter

rope handle many times depending on how

badly the unit is flooded. If engine fails to

start refer to the troubleshooting chart or call

your Authorized Service Dealer.

CUTTING METHODS

IMPORTANT POINTS

Cut wood only. Do not cut metal, plastics,

masonry, non-wood building materials, etc.

Stop the saw if the chain strikes a foreign

object. Inspect the saw and repair parts

as necessary.

Keep the chain out of dirt and sand. Even a

small amount of dirt will quickly dull a chain

and increase the possibility of kickback.

Practice cutting a few small logs using the

following techniques to get the “feel” of

using your saw before you begin a major

sawing operation.

Squeeze the throttle trigger and allow the

engine to reach full speed before cutting.

Begin cutting with the saw frame against

the log.

Keep the engine at full speed the entire

time you are cutting.

Allow the chain to cut for you. Exert only

light downward pressure.

Release the throttle trigger as soon as the

cut is completed, allowing the engine to

idle. If you run the saw at full throttle with-

out a cutting load, unnecessary wear can

occur.

To avoid losing control when cut is com-

plete, do not put pressure on saw at end

of cut.

Stop the engine before setting the saw

down.

TREE FELLING TECHNIQUES

WARNING:

Do not cut near buildings or

electrical wires if you do not know the direc-

tion of tree fall, at night since you will not be

able to see well, or during bad weather such

as rain, snow, or strong winds. as fall is un-

predictable.

Carefully plan your sawing operation in ad-

vance. You need a clear area all around the

tree so you can have secure footing. Check

for broken or dead branches which can fall

on you causing serious injury.
Natural conditions that can cause a tree to

fall in a particular direction include:

The wind direction and speed.

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.

Weight and branches on one side.

Surrounding trees and obstacles.

Look for decay and rot. If the trunk is rotted,

it can snap and fall toward the operator.
Make sure there is enough room for the tree to

fall. Maintain a distance of

2-1/2

tree lengths

from the nearest person or other objects. En-

gine 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.
