Checking the chain brake

Do not work with the chain saw without first checking the
chain brake!
- Grasp the tubular handle firmly with one hand and hold the

1
- Start the motor as described (make sure you have a good
footing, and place the chain saw on the ground in such a
way that the guide bar is free of contact).
- Switch on the motor and press the hand guard (1) in the
direction of the arrow with the back of your hand until the
chain brake engages. The chain should stop immediately.
- Switch the motor off Immediately and release the chain
brake.
Important: If the saw chain does not stop instantly when
you carry out this test, do not under any circumstances
use the saw! Take the chain saw to a MAKITA service
center.

Testing the run-out brake

Do not work with the saw without first testing the run-out
brake!
- Grasp the tubular handle firmly with one hand and hold the
grip with the other.
- Start the motor as described (make sure you have a good
footing, and place the chain saw on the ground in such a
way that the guide bar is free of contact).
- Switch the motor on and then back off. The chain should
come to a full stop within two second of switching off the
motor.
Important: If the saw chain does not stop within two
second when you carry out this test, do not use the saw!
Inspect the carbon brushes (see page 19).
Checking the chain
lubrication
Never saw when a sufficient chain lubrication is not guaranteed.
Otherwise the life of the sawing device will be reduced. Before
starting work check the oil level in the tank and the oil feeding.
Check the fed oil quantity by following the instructions below:
- Start the electric chain saw.
- Hold the running chain saw approx. 15 cm above a trunk or
the ground (use an appropriate surface).
If the lubrication is sufficient, you will see a light oiltrace because
oil will be centrifuged from the chain saw. Pay attention to the
direction the wind is blowing and avoid unnecessary exposure
to the oil spray!
