Check the chain brake as follows:
1. Hold the chain saw with both hands when
switching it on. Hold the rear handle with your
right hand, the front handle with your left. Make
sure that the bar and the chain do not contact
with any object.
2. First press the lock-off button, then the switch
trigger. The saw chain starts immediately.
3. Press the front hand guard forwards using the
back of your hand. Make sure that the saw chain
comes to an immediate standstill.
CAUTION:
• If the saw chain does not stop immediately, do not
use the saw under any circumstances. Consult
Makita authorized service centers.
Checking the run-down brake
Switch on the chain saw.
Release the switch trigger completely. Make sure the
saw chain comes to a standstill within a second.
CAUTION:
• If the saw chain does not stop immediately, do not
use the saw under any circumstances. Consult
Makita authorized service centers.
Checking the chain oiler
Before starting work, check the oil level in the tank, and
the oil delivery.
The oil level can be seen in the oil level sight shown in
the figure.

Check the oil delivery as follows:
Start the chain saw.
With the saw running, hold the saw chain approximately
15 cm above a tree trunk or the ground. If lubrication is
adequate, the oil spray will produce a light oil trace.
Observe the wind direction, and do not expose yourself
to the oil spray unnecessarily.
CAUTION:
•
If an oil trace is not formed, do not use the saw. The
lifespan of the chain will otherwise be reduced.
Check the oil level. Clean the oil feed groove and the
oil feed hole in the bar (refer to "MAINTENANCE ").
