Operation

WARNINGS.

Always follow the safety instructions given at the front

of this manual. This chainsaw must only be used for

cutting wood. It must not be used for cutting other types

of material. Do not use the chainsaw as a lever for lifting,

moving or splitting objects.

Do not attach the chainsaw to a fixed stand.

Do not attach any devices to the chainsaw other than

those specified by the manufacturer.

Helpful hints

Do not force the saw into the cut. Apply only light pressure

whilst running the engine at full throttle.

If the saw chain gets caught in the cut, do not try to

remove it by twisting the guide or pulling forcibly. Use a

lever or wedge to open up the cut so that the saw chain

is freed.

While cutting, always:

Run the chainsaw motor at full revs. This makes the job

safer, as there is less chance of pull-in or kick-back.

Position your body to the left of the chainsaw so if it kicks

back uncontrollably, it goes over your right shoulder,

never stand in the cutting line of the saw.

Keep a firm grip with your left hand on the front handle,

with your thumb securely below the handle.

The swivel of your wrist in a kick-back situation will

activate the chain brake.

Make sure the chain is tensioned correctly.

Guard against kickback

Check the operation of the chain brake each time you use

the chainsaw.
Run the saw at full throttle for 1-2 seconds then push the

front guard (8) forwards. The chain should stop immediately.

If the chain is slow to stop or only slows down you must

take the tool to an authorised repair centre to have the

brake band and clutch drum replaced. Disengage the chain

brake by pulling the front guard backwards until you hear

a click. Do not use the chainsaw if the chain brake is not

operating correctly.

Be constantly aware of the position of the upper quadrant

of the blade tip. This is the part that triggers a kickback

when it hits resistance.

Never engage the upper quadrant of the guide bar with

whatever you are cutting and avoid contact with any

hidden branches or obstructions. Ensure there is a clear

work area.

Always clear away brush, vegetation and any obstructing

debris before attempting a cut that might trigger a

kickback.

Avoid cuts that will cause the chainsaw to jam in a tree

trunk or limb.

Observe the size of wood shavings, if they become dusty

your chain could need sharpening.

Felling a tree

WARNING.

Felling a tree should only be done by

trained operators.
Decide the direction in which

you wish the tree to fall taking

into account the direction

of the wind, the position of

branches, lean of the tree,

ease of subsequent limbing

and bucking and other factors

prevalent at the time.
1. Clear the area around the tree and make sure that you

have a good foothold and clear retreat path.

2. Ensure that others in the area are aware of the felling

and ensure people and animals are well clear.

3. Make a notch cut one-third of the way into the tree on the

felling side.
