SAW BLADE ASSEMBLY

A. Turn around the gear housing shaft until one of the driving disc

holes indexes the respective gear housing hole.

B. Insert a locking pin (0 4.5 mm) into the hole to lock the shaft.
C. Slack off the nut (Note! Left-hand threads!) and remove the

slightly curved washer.

D. Put the clearing saw blade on the hub. Check that the rotation

direction is correct. Fit the washer and the nut. The nut is to be
tightened with a torque of 35-50 Nm (3.5-5 kpm). Use the box
spanner of the clearing saw tool kit. Grasp the key shaft as near
the blade guard as possible.

NOTE!

When slacking off and tightening the saw blade nut, there is a risk
that your hand gets in touch with the saw blade teeth. Avoid this

by holding your hand near to the blade guard and by using a box

spanner provided with a shaft of sufficient length.
The arrow on the illustration shows the area, in which you should

let the box spanner work when slacking off and tightening the nut.

FUEL AND OIL

The engine is of two-stroke model and is to be lubricated with an

oil-petrol mixture of certain proportions.

When using normal two-stroke oils we recommend a ratio of 1 part

of oil to 25 parts of petrol (4%).

When using a so-called pre-mixed two-stroke oil, we recommend

1 part of oil to 20 parts of petrol (5%).

For the use of Husqvarna Twostroke Oil we recommend 1 part of
oil to 50 parts of petrol (2%).
Below table shows the various oil-mixture proportions.
