above the drive sprocket and engage it in the groove
on the guide bar. Start on the top edge of the guide
bar. (Fig. 51)
4. Make sure that the edges of the cutting links face
forward on the top edge of the guide bar.
Introduction
WARNING: Read and understand the safety
chapter before you use the product.
To do a function check before you use
the product
1. Do a check of the chain brake (A) to make sure that
it operates correctly and that it is not damaged.
2. Do a check of the rear right hand guard (B) to make
sure that it is not damaged.
3. Do a check of the power trigger and the power
trigger lockout (C) to make sure that they operate
correctly and that they are not damaged.
4. Do a check of the keypad (D) to make sure that it
operates correctly.
5. Make sure that there is no oil on the handles (E).
6. Do a check to make sure that all parts are correctly
attached and not damaged or missing.
7. Do a check of the chain catcher (F) to make sure
that it is attached correctly.
8. Do a check of the chain tension (G).
9. Charge the battery (H) and make sure that it is
correctly attached to the product.
10. Make sure that the saw chain stops when you
release the power trigger. (Fig. 52)
Chain oil
All Husqvarna chainsaws have an automatic chain
lubrication system. On some models the oil flow is also
adjustable.
Think about the following when you select a chain oil:
(Fig. 53)
•
The oil tank lasts approximately three battery
charges. This applies only if you use the correct
chain oil. If the chain oil is too thin, it will not last that
long.

5. Assemble the drive sprocket cover and steer the
chain adjuster pin to the hole in the guide bar.
6. Make sure that the drive links of the saw chain fit
correctly on the drive sprocket.
7. Make sure that the saw chain is correctly engaged in
the groove in the guide bar.
8. Tighten the saw chain. See
on page 23 for instructions.
Operation
•
Chain oil must show good adherence to the saw
chain and also keep its flow quality during warm
summer and cold winter weather.
•
Use an oil of the right grade (suitable viscosity
range) to agree with the air temperature. In
temperatures below 0°C (32°F) some oils become
too thick. This can cause the oil pump to overload
and result in damage to the oil pump components.
•
Use the recommended cutting equipment. A guide
bar that is too long will use more chain oil.
•
Turn to your servicing dealer when you select a
chain oil.
WARNING: Do not use waste oil! Waste oil
is dangerous to you and the environment.
Waste oil also causes damage to the oil
pump, the guide bar and the saw chain.
WARNING: If the lubrication of the cutting
equipment is not sufficient, it can cause the
saw chain to break. This can cause serious
injury or death to the operator.
CAUTION: If you use vegetable based chain
oil, clean the groove in the guide bar and
saw chain before long-term storage.
Otherwise there is a risk of the saw chain
oxidizing, which causes the saw chain to
become stiff and that the bar tip sprocket
gets clogged.
To connect the battery charger
1. Connect the battery charger to the voltage and
frequency that is specified on the rating plate.
2. Put the plug in a grounded socket outlet.
Note: The battery does not charge if the battery
temperature is more than 50 °C/122 °F. If the
temperature is more than 50 °C/122 °F, the battery
charger makes the battery become cool.
