Lubricating Cutting Equipment - Husqvarna 327PT5S Operator's Manual

- Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the
underside of the bar.
- Tighten the bar nut using the combination spanner.
Check that the chain can be pulled round easily by hand.

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 chain saw 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.
• 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 machine and the environment.

GENERAL SAFETY PRECAUTIONS
Filling with chain oil
The oil pump is preset at the factory to satisfy most
lubrication requirements. A full oil tank normally lasts
about the same time as a full fuel tank. Therefore check
the amount of oil in the oil tank when filling the fuel to
prevent damage to the saw chain and bar that may arise
due to a lack of lubrication.
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.
Adjusting chain lubrication
When cutting dry or hard species of wood it may be
necessary to increase lubrication. Turn the adjuster screw
clockwise to increase the oil flow. Remember that this will
increase oil consumption, check the level in the oil tank
regularly. Turn the adjuster screw anticlockwise to
decrease the oil flow.
