MAINTENANCE

Sharpening the saw chain

When working on the saw chain you must always pull

out the power supply plug and wear protective gloves.

The chain needs sharpening when:

- the sawdust from sawing humid wood looks like wood flour.

- the saw chain penetrates the wood only under great

pressure.

- the cutting edge is visibly damaged.

- the sawing device is pulled to the left or the right during the

sawing operation. This is caused by uneven sharpening of

the chain or by damage to one side of it.

Important: Sharpen frequently, but without removing

too much metal!

Generally, 2-3 strokes of the file will be enough.

Have the chain resharpened in a service center when you

have sharpened it yourself several times.

Checking the chain lubrication

Never saw when a sufficient chain lubrication is not guaranteed.

Otherwise the life of the sawing device will be reduced. Before

starting work check the oil level in the tank and the oil feeding.

Check the fed oil quantity by following the instructions below:

- Start the electric chain saw.

- Hold the running chain saw approx. 15 cm above a trunk or

the ground (use an appropriate surface).

If the lubrication is sufficient, you will see a light oiltrace

because oil will be centrifuged from the chain saw. Pay attention

to the direction the wind is blowing and avoid unnecessary

exposure to the oil spray!

Proper sharpening:

CAUTION:

Use only chains and guide bars designed for this saw (see

the Extract from the spare-parts list)!

- All cutters must be of the same length (dimension a).

Cutters with different lengths result in rough running of the

chain and can cause cracks in the chain.

- Minimum cutter length is 3 mm (0.11"). Do not resharpen

the chain when the minimum cutter length has been reached;

at this point, the chain must be replaced (see the Extract

from the spare-parts list and "Replacing the chain").

- The depth of the cut is determined by the difference in

height between the depth limiter (round nose) and the

cutting edge.

- The best results are obtained with a depth-limiter depth of

0.65 mm (.025").

CAUTION:

Excessive depth increases the

risk of kickback!

3 mm (0.11”)

Do not work with the saw without first testing the run-out

brake!

- Start the motor as described (make sure you have a good

footing, and place the chain saw on the ground in such a

way that the guide bar is free of contact).

- Grasp the tubular handle firmly with one hand and hold the

grip with the other.

- Switch the motor on and then back off. The chain should

come to a full stop within two second of switching off the

motor.

Important: If the saw chain does not stop within two

second when you carry out this test, do not use the

saw! Inspect the carbon brushes (see page 16).
