SAFETY INSTRUCTIONS

D. Correction of raker clearance

• When correction of the raker clearance is made the teeth must be newly sharpened.

We recommend that you adjust the raker clearance every third time you sharpen the chain. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

A FLAT FILE and an

RAKER CLEARANCE GAUGE are required to correct the raker clearance.

• Place the gauge over the raker lip.

Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge.

Tensioning the saw chain

!WARNING!

A slack chain may jump off and cause serious or even fatal injury.

• The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.

Check the chain tension every time you refuel.

NOTE! A new saw chain has a running-in period during which you should check the tension more frequently.

Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.

1.Release the two nuts.

2.Adjust the chain tension by turning the chain tensioning screw.

3.Tighten both nuts.

Chain lubrication

A. Checking

Check the chain lubrication each time the petrol is replenished.

Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.

The oil flow can be regulated with the screw

(A)on the hydraulic motor.

Turn the screw anti- clockwise to increase the flow.
