Lubricating Cutting Equipment - Husqvarna T540 XP II Manual De Instrucciones

combination spanner. Tighten the chain until it does
not sag from the underside of the bar.
• Use the combination spanner to tighten the bar nut
while holding up the tip of the bar. Check that you can
pull the saw chain round freely by hand, and that there
is no slack on the underside of the bar.
The position of the chain tensioning screw on our
chainsaws varies from model to model. See instructions
under the heading What is what? to find out where it is on
your model.

Lubricating cutting equipment

WARNING! Poor lubrication of cutting
!
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
As a chainsaw manufacturer we have developed an
optimal chain oil which has a vegetable oil base. 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.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage. Otherwise there is a risk
of the saw chain oil oxidizing, which will result in the saw
chain becoming stiff and the bar tip sprocket jamming.

GENERAL SAFETY PRECAUTIONS
Filling with chain oil
• All our chainsaws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
• The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you also use the
recommended cutting equipment (a bar that is too
long will use more chain oil).
Checking chain lubrication
• Check the chain lubrication each time you refuel.
Aim the tip of the bar at a light coloured surface about
20 cm (8 inches) away. After 1 minute running at 3/4
throttle you should see a distinct line of oil on the light
surface.
If the chain lubrication is not working:
• Check that the oil channel in the bar is not obstructed.
Clean if necessary.
