GENERAL SAFETY PRECAUTIONS

Lubricating cutting equipment

Chain oil

Chain oil must demonstrate good adhesion to the chain

and also maintain its ﬂow characteristics regardless of

whether it is warm summer or cold winter weather.

As a chain saw manufacturer we have developed an

optimal chain oil which, with its v

egetable oil base, is also

biodegradable. We recommend the use of Universal

Outdoor Accessories Chain Oil (Bio) for both maximum

chain life and to minimise enviromental damage. If

Universal Outdoor Accessories Chain Oil (Bio) is not

available, standard chain oil is recommended.

Never use waste oil! Using waste oil can be dangerous

to you and damage the machine and environment.

Filling with chain oil

• All our chain saws have an automatic chain lubrication

system. On some models the oil ﬂow is also

adjustable.

• The saw chain oil tank and the fuel tank are designed

so that the fuel r

uns out before the saw chain oil.

However, this safety feature requires that you use the

ight sort of chain oil (if the oil is too thin it will run out

before the fuel), and that you adjust the carburetor as

recommended (a lean mixture may mean that the fuel

lasts longer than the oil) and that you also use the

recommended cutting equipment (a bar that is too

long will use more chain oil).

Checking chain lubrication

• Check the chain lubrication each time you refuel. See

instructions under the heading Lubricating the bar tip

sprocket.

Aim the tip of the bar at a light coloured surface about

20 cm (8 inches) a

way. After 1 minute running at 3/4

throttle you should see a distinct line of oil on the light

surface.

If the chain lubrication is not working:

• Check that the oil channel in the bar is not obstructed.

Clean if necessar

• Check that the groove in the edge of the bar is clean.

Clean if necessary.

• Check that the bar tip sprocket turns freely and that

the lubricating hole in the tip sprocket is not blocked.

Clean and lubricate if necessary.

If the chain lubrication system is still not working after

carr

ying out the above checks and associated measures

you should contact your service agent.

Chain drive sprocket

The clutch drum is ﬁtted with a Spur sprocket (the chain

sprocket is welded on the drum (D)).

(4)

Regularly check the degree of wear on the drive sprocket.

Replace if wear is excessive. Replace the drive sprocket

whenever you replace the chain.

Checking wear on cutting equipment

Check the chain daily for:

• Visible cracks in rivets and links.

• Whether the chain is stiff.

• Whether rivets and links are badly worn.

Replace the saw chain if it exhibits any of the points

above.

We recommend you compare the existing chain with a

new chain to decide how badly the existing chain is worn.

When the length of the cutting teeth has worn down to

only 4 mm the chain m

ust be replaced.

(9)

Guide bar

Check regularly:

• Whether there are burrs on the edges of the bar (A).

Remo

ve these with a ﬁle if necessary.

(19)

• Whether the groove in the bar has become badly worn

(B). Replace the bar if necessary.

(19)

• Whether the tip of the bar is uneven or badly worn. If

a hollow forms on the underside of the bar tip this is

due to running with a slack chain.

• To prolong the life of the bar you should turn it over

daily

WARNING! Poor lubrication of cutting

equipment may cause the chain to snap,

which could lead to serious, even fatal

injuries.

IMPORTANT! When using vegetable based saw chain

oil, dismantle and clean the groove in the bar and saw

chain before long-term storage. Otherwise there is a risk

of the saw chain oil oxidizing, which will result in the saw

chain becoming stiff and the bar tip sprocket jamming.

WARNING! Most chain saw accidents

happen when the chain touches the

operator.

Wear personal protective equipment. See

instructions under the heading ”Personal

protective equipment”.

Do not tackle any job that you feel you

are not adequately trained for. See

instructions under the headings

Personal protective equipment, How to

avoid kickback, Cutting equipment and

General working instructions.

Avoid situations where there is a risk of

kickback. See instructions under the

heading Machine

′′

s safety equipment.

Use the recommended protective

equipment and check its condition. See

instructions under the heading General

working instructions.

Check that all the chain saw safety

features are working. See instructions

under the headings General working

instructions and General safety

precautions.
