Adjusting The Chain Lubrication - Makita UC3041A Instruction Manual

A chain which is too loose can jump off the bar, and
therefore presents an accident risk.
If the chain is too loose: Refer to the section titled "
Adjusting saw chain tension " and adjust
chain tension again.
Checking the switch action
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the
"OFF" position when released.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, depress the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
Do not pull the switch trigger hard without depressing
the lock-off button. This may cause switch breakage.
Checking the chain brake
NOTE:
If the chain saw fails to start, check whether the
•
chain brake is released. To release the chain
brake, pull the hand guard backwards firmly until
you feel it engage.

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

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 ").
