• Fold the knob back in to lock the tensioning.

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.

Never use waste oil! Using waste oil can be dangerous

to you and damage the machine and environment.

Filling with chain oil

• Always use mineral based chain oil. (Figure 33)

• Contact your service agent when choosing 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 is designed to last aproximately

three battery charges. However, this safety feature

requires that you use the right sort of chain oil (if the

chain oil is to thin it will last shorter time).

• Never use waste oil. This results in damage to the oil

pump, the bar and the chain.

• It is important to use oil of the right grade (suitable

viscosity range) to suit the air temperature.

• In temperatures below 0°C (32°F) some oils become

too viscous. This can overload the oil pump and result

in damage to the oil pump components.

Checking chain lubrication

• Check the chain lubrication every third battery charge.

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

20 cm (8 inches) away. After 1 minute running at 3/4

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

surface. (Figure 34)

If the chain lubrication is not working:

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

Clean if necessary. (Figure 35)

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

Clean if necessary. (Figure 36)

• 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. (Figure 37)

If the chain lubrication system is still not working after

carrying out the above checks and associated measures

you should contact your service agent.

Chain drive sprocket

The drive system is ﬁtted with a drive sprocket.

(Figure 38)

Regularly check the degree of wear on the drive sprocket.

Replace if wear is excessive.

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 must be replaced.

Guide bar

Check regularly:

• Whether there are burrs on the edges of the bar.

Remove these with a ﬁle if necessary. (Figure 39)

• Whether the groove in the bar has become badly

worn. Replace the bar if necessary.

• 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. (Figure 40)

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

daily. (Figure 41)

WARNING! Poor lubrication of cutting

equipment may cause the chain to snap,

which could lead to serious, even fatal

injuries.

WARNING! Most chain saw accidents

happen when the chain touches the

operator.

Wear personal protective equipment. See

instructions under the ”Personal

protective equipment” heading.

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 headings

Technical data and General safety

precautions.

Check that all the chain saw safety

features are working. See instructions

under the headings General working

instructions and General safety

precautions.

Never use a chain saw by holding it with

one hand. A chain saw is not safely

controlled with one hand. Always have a

secure, ﬁrm grip around the handles with

both hands.
