Husqvarna How to Adjust Chain on Chainsaw for Optimal Performance

Page 10

SAFETY INSTRUCTIONS

D. Adjusting 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 chain has a running-in period during which you should check and adjust the chain tension more frequently.

As a rule the chain should be tensioned as tightly as possible, but not so tight that you cannot pull it round freely by hand.

1. Undo the bar nut.

2. Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. Tighten the chain until it no longer hangs slack beneath the bar.

3. Use the combination spanner to tighten the blade nut while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand.

Lubricating cutting equipment

!WARNING!

Poor lubrication of cutting equipment may cause the chain to snap and lead to serious, even fatal injuries.

A.Chain oil

Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather.

As a chainsaw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage.

If our own chain oil is not available, standard chain oil is recommended.

In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used.

Never use waste oil!

This is dangerous for yourself, the saw and the environment.

B. Filling with chain oil

The oil pump is preset at the factory to meet most lubrication requirements and a full oil tank will last about half as long as a tank of fuel. You should therefore check the level in the oil tank regularly to avoid damaging the chain and bar by running out of oil.
