NOTE
The saw chain has been tensioned correctly when:
■
It is in contact with the underside of the chain bar and can be pulled through by hand.
■
It can be lifted by 3
– 4 mm in the middle of the chain bar.
CAUTION!
Danger of injury due to the saw chain jumping off!
An insufficiently tensioned saw chain can jump off during operation and lead to injury.
■
Frequently check the chain tension. The chain tension is too low if the drive links come out
of the groove on the underside of the chain bar.
■
Re-tension the saw chain properly if the chain tension is too low.
5.5 Testing the function of the chain brake
The chain saw has a manual chain brake that is triggered by the hand guard, for example if
kickback occurs. When the chain brake is triggered, the saw chain is abruptly stopped and the
motor switched off.
DANGER!
Danger of fatal injury as a result of negligent handling!
Extremely serious injury and even fatal injury can be caused as a result of careless and
unexpected movements of the chain saw.
■
Pay attention to safety and work with a high level of concentration when using the chain
saw.
■
Do not press any switch when releasing the chain brake.
WARNING!
Danger of fatal injury and danger of extremely severe injury due to a defective
chain brake
Extremely serious injury and even fatal injury of the operator can be caused if the chain brake
does not function, e.g. due to kickback by the running saw chain.
■
Check the chain brake each time before starting work.
■
Do not operate the chain saw if the chain brake is defective. In this case, have the chain
saw checked and repaired by a service workshop.
5.6 Function test of the chain brake with the motor switched off (figure 8)
WARNING - Always remove the battery before performing maintenance.
Wear heavy duty gloves
1. To switch off the chain brake, pull (08/A) the hand guard (08/1) in the direction of the handle
(08/2). The saw chain can be pulled through by hand.
2. Push the hand guard (08/1) forwards (08/B) to switch on the chain brake. It must not be
possible to pull the saw chain through.
