GENERAL SAFETY PRECAUTIONS
Tensioning the chain
! | WARNING! A slack chain may jump off | |
the bar and cause serious or even fatal | ||
| ||
| injury. |
The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
Check the chain tension every time you refuel. NOTE! A new chain has a
Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.
•Loosen the bar nut that holds the clutch cover and chain brake. Use the combination spanner.
•Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the 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 chain saws 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 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.
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
Filling with chain oil
•All our chain saws 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. See instructions under the heading Lubricating the bar tip sprocket.
Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4
