Introduction

This manual is an integral part of the chainsaw and should be kept with it at all times. If the chainsaw is re-sold this manual should be included in the sale.

Safety Messages

A safety message is to alert you to potential dangers that could hurt you or others. Each safety message is preceded by one of three words DANGER, WARNING or CAUTION.

These words mean

DANGER: YOU WILL BE KILLED OR SERIOUSLY INJURED IF

YOU FAIL TO FOLLOW THE INSTRUCTIONS.

WARNING: YOU CAN BE KILLED OR SERIOUSLY INJURED IF

YOU FAIL TO FOLLOW THE INSTRUCTIONS.

CAUTION: YOU CAN BE SERIOUSLY INJURED IF YOU FAIL TO

FOLLOW INSTRUCTIONS.

Each safety message tells you what the hazard is, what can happen and what you can do to avoid and reduce injury.

There are other important messages preceded with the word

NOTICE .

NOTICE: MEANS YOUR CHAINSAW OR OTHER PROPERTY

COULD BE DAMAGED IF YOU FAIL TO FOLLOW

INSTRUCTIONS.

The purpose of these messages is to help prevent damage to you, your chainsaw, other property and the environment.

General Safety Instructions

Even when used as prescribed it is not possible to eliminate all residual risk factors. Use with caution.

Keep guards in position

• Always keep guards in position, in good working order, correctly

adjusted and aligned. Never attempt to use a tool without any guard

supplied with it.

Remove adjusting keys

• Always check to see that keys and adjusting wrenches are removed

from tool before turning on.

Clean work area

• Accidents occur where benches and work areas are cluttered or

dirty, floors must be kept clear, avoid working where the floor

is slippery.

Dangerous environment

• Provide adequate surrounding work space and keep area well lit.

Do not use tools where there is a risk of explosion or fire from

combustible material, flammable liquids, flammable gases

or dust of an explosive nature.

Children & Pets

from your work. Make your workshop child-proof. Lock tools

away where children can’t get access to them.

Use the correct tool

• Don’t force, or attempt to use a tool for a purpose it was not

designed for. Do not use a small tool to do the job of a heavy duty

tool.

Wear correct clothing and footwear

• Don’t wear loose clothing, neckties or jewellery or other items which

may get caught in moving parts. Wear non-slip footwear, cover or

tie back long hair. Use safety footwear if necessary.

Protect your head

• Wear safety goggles at all times, every day glasses are not

sufficient for eye protection, as lenses are not impact resistant and

could shatter. Use an approved face or dust mask when operation

creates dust. Ensure dust extraction equipment is functioning

and correctly used. Hearing protection should be used if the sound

intensity level for the operator could exceed 80dB(A). Use a hard

hat where there is a risk of falling objects or striking your head on

low level obstructions.

Protect yourself from vibration.

• Hand held tools may produce vibration. Vibration can cause

disease. Gloves to keep the operator warm and dry and therefore

maintain good blood circulation in the fingers may help. This tool

has not been designed for extended or industrial operation.

Secure work

• Always secure work. Where practical use a clamp or vice, it will

allow you to use both hands to operate your tool.

Keep your balance

• Don’t over reach, keep proper footing at all times to ensure

correct balance.

Maintain your tool

• Keep your tool in good working order, keep tools sharp and clean

for best and safest performance. Ensure ventilation holes are kept

clean and unrestricted at all times.

Accessories

• The use of any attachment or accessory other than those

mentioned in this manual could result in damage or injury. The use

of improper accessories could be dangerous.

Never stand on your power tool

• Standing on your tool could cause serious injury if the tool is tipped

or if the cutting tool is accidentally contacted. Do not store materials

above or near the tool so that it is necessary to stand on the tool or

its stand to reach them.

Check for damaged or missing parts.

• Before each use check if any part of the power tool is damaged or

missing, check carefully that it will operate properly and perform its

intended function. Check alignment of moving parts for binding. Any

guard or other part that is damaged should be correctly repaired or

replaced. Do not use if the power switch does not turn the power on

and off. Check any other condition that may affect the safety of the

power tool. DO NOT USE IF DEFECTIVE.

Direction of feed

• Feed work into a blade or cutter against the direction of rotation of

the blade or cutter only.

Don’t leave the tool running unattended

• Always wait until your power tool has come to a complete stop

before leaving it.

4. Fit the chain cover to the power unit and fasten the nuts to finger

tightness.

5. While holding up the tip of the bar, adjust the chain tension by

turning the tensioner screw (located to the side of the guide bar)

until the tie straps just touch the bottom side of the bar rail.

6. Tighten the nuts securely with the bar tip held up (12~15N.m).

Then check the chain for smooth rotation and proper tension while

moving it by hand. If necessary, re-adjust with the chain cover

loose.

NOTE:

A new chain will stretch when first used. Check and re-adjust the tension frequently as a loose chain can easily de-rail or cause rapid wear of itself and the guide bar.

Fuel and chain oil

Fuel

• The motor uses two stroke fuel, a mixture of petrol and a 2 stroke

lubricant at 25:1

• Use a branded 90 octane or higher unleaded petrol.

NOTE two stroke fuel may separate, Shake fuel container

thoroughly before each use. Do not mix more fuel than you

expect to use within one month.

CAUTION

Ensure the brake is fully operational prior to use.

To do this:

(1) Turn off the engine.

(2) Holding the chainsaw horizontally, release your hand from the front handle, hit the tip of the guide bar to a stump or a piece of wood, and confirm brake operation. Operating level varies by bar size. (Fig. 5). In case the brake is not effective. Refer to the g uarantee on the back of this manual about inspection and repairing. The engine, if being kept rotated at high speed with the brake engaged, will heat the clutch, causing a problem. When the brake is operated while in operation, immediately release your fingers from the throttle lever and keep the engine idling.

Sawing

WARNING!

• Before proceeding to your job, read the following sections. It is

recommended to first practice sawing easy logs. This also

helps you get accustomed to your unit.

• Always follow the safety regulations. The chain saw must only

be used for cutting wood. It is forbidden to cut other types of

material. Vibrations and kickback vary with different materials

and the requirements of the safety regulations would not be

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

moving or splitting objects. Do not lock it over fixed stands.

• It is not necessary to force the saw into the cut. Apply only

it out by force, but use a wedge or a lever to open the way.

Check for fuel leakage and loose fastenings and damage to major parts. Especially handle joints and guide bar mounting. If any defects are found, make sure to have them repaired before operating again.

Periodical service points

1. Cylinder fins

Dust clogging between the cylinder fins will cause overheating of the engine. Periodically check and clean the cylinder fins after removing the air cleaner and the cylinder cover.

When installing the cylinder cover, make sure that switch wires and grommets are positioned correctly in place.

NOTE:

Be sure to block the air intake hole prior to cleaning

2. Spark plug (Fig.12)

Fig.12

This saw is equipped with a chain brake that will stop the chain in the event of kickback if operating properly. You must check the chain brake operation before each usage by running the saw at full throttle for 1-2 seconds and pushing the front hand guard forward.

The chain should stop immediately with the engine at full speed. If the chain is slow to stop or does not stop, replace the brake band and clutch drum before use.

It is extremely important that the chain brake be checked for proper operation before each use and that the chain is sharp in order to maintain the kickback safety level of this saw. Inadequate maintenance, or incorrect replacement of the bar or chain may increase the risk of serious personal injury due to kickback.

Felling a tree (Fig. 7)

WARNING!

When you fell a tree, be sure to warn your neighbouring workers of the danger.

(1) Notch cut

(2) Felling cut

(3) Felling direction

Fig.7

1. Choose the felling direction considering the wind, lean of the tree,

location of heavy branches, ease of job after felling and other

factors.

2. While clearing the area around the tree, arrange a good foothold

and retreat path.

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

4. Make a felling cut from the opposite side of the notch and at a

level slightly higher than the bottom of the notch.

634009_Instructions.indd 4

First check to which side the limb is bent. Then make the initial cut from the bent side and finish by sawing from the opposite side.

WARNING!

Be alert to the possibilities of spring back from a cut limb.
