of the saw chain before you operate the product. Tighten
the saw chain as tightly as possible, but it must be
possible to pull the saw chain around freely by hand.
Note:
A new saw chain has a running-in period. Do a
check of the tension more frequently during this period.
1. Turn the locking knob counterclockwise to unlock the
chain tension adjuster. (Fig. 72)
2. Turn the chain tension adjuster clockwise to tighten
the saw chain. Apply as much tension to the saw
chain as possible. It must be tight against the guide
bar.
3. Make sure that you can pull the saw chain around
freely by hand and that it does not hang from the
guide bar. (Fig. 73)
4. Turn the locking knob clockwise to lock the chain
tension adjuster.
To lubricate cutting equipment
WARNING:
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
WARNING:
Waste oil is dangerous for persons, the
product and for the environment.
Saw chain oil
• Use saw chain oil of good adherence to the saw
chain. The saw chain oil must keep its viscosity in
all weather, for example, during hot summer or cold
winter.
• Use Husqvarna chain oil for maximum saw chain life
and to keep environmental damage to a minimum.
If Husqvarna saw chain oil is not available, use a
standard saw chain oil.
• In areas where oil for lubrication of saw chains is not
available, use EP 90 transmission oil.
Do a check of the level of oil in the oil tank regularly to
prevent damage to the saw chain and guide bar.
(Fig. 74)
To fill with oil
Fill with saw chain oil after 1 hour of operation or when
the battery is empty.
1. Open the oil tank cap on the top of the saw head.
2. Fill with Husqvarna saw chain oil.
3. Attach the oil tank cap.

nose of the guide bar at a light color surface almost
20 cm (8 in) away.
2. After 1 minute of running, a line of oil shows on the
light surface.
3. If you cannot see the line of oil after 1 minute, clean
the oil channel in the guide bar. Clean the groove in
the edge of the guide bar.
4. Start the product and let it run at 3/4 speed. Point the

5. After 1 minute of running, a line of oil shows on the
light surface.
6. If you cannot see the line of oil after 1 minute, speak
to your approved dealer.
To do a check if lubrication does not work
1. Check that the oil channel in the bar is not
obstructed. Clean if necessary. (Fig. 75)
2. Check that the oil channel in the gear housing is

3. Check that the bar tip sprocket turns freely. If the
chain lubrication system is still not working after
carrying out the above checks you should contact
your service workshop. (Fig. 76)
To do a check of the guide bar
1. Make sure that the oil channel is not blocked. Clean
if it is necessary. (Fig. 77)

bar. Remove the burrs using a file. (Fig. 78)
3. Clean the groove in the guide bar. (Fig. 79)
4. Examine the groove in the guide bar for wear.
Replace the guide bar if it is necessary. (Fig. 80)
5. Examine if the guide bar tip is rough or very worn.
(Fig. 81)
6. Make sure that the bar tip sprocket turns freely and
that the lubricating hole in the bar tip sprocket is not
blocked. Clean and lubricate if it is necessary. (Fig.
