chain, wear of the guide bar and breakage of the
adjusting dial.
• A chain which is too loose can jump off the bar, and
therefore presents an accident risk.
• Carry out the procedure of installing or removing saw
chain in a clean place free from sawdust and the like.
Engaging extension cord
CAUTION:
• Make sure that the extension cord is unplugged to the
mains outlet. (Fig. 19)
When engaging the extension cord, secure it to the chain
saw's cord with the cord hook.
Attach the cord hook about 100 - 200 mm from the
extension cord connector. This helps prevent
unintentional disconnection.
OPERATION
CAUTION:
• Hold the tool firmly with right hand on the rear handle
and left hand on the front handle when performing the
tool.
Switch action (Fig. 20)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before checking function on the switch
trigger.
• 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.
Lubrication
CAUTION:
• Always be sure that the tool is switched off and
unplugged before lubricating the saw chain.
Lubricate the saw chain and bar using biologically
degradable saw chain oil with an adhesion agent. The
adhesion agent in the saw chain oil prevents the oil from
being thrown off the saw excessively quickly. Mineral oils
must not be used, as they are harmful to the environment.
(Fig. 21)
CAUTION:
• Do not operate the chain saw when the tank is empty.
Replenish the oil in due time before the tank is empty.
• Prevent the oil from coming into contact with the skin
and eyes. Contact with the eyes causes irritation. In the
event of eye contact, flush the affected eye
immediately with clear water, then consult a doctor at
once.
• Never use waste oil. Waste oil contains carcinogenic
substances. The contaminants in waste oil cause
accelerated wear of the oil pump, the bar and the
chain. Waste oil is harmful to the environment.
To fill the oil, perform the following steps: (Fig. 22)
1. Clean the area around the oil filler cap thoroughly to
prevent any dirt from entering the oil tank.

2. Unscrew the oil filler cap and add oil up to the lower
edge of the filler neck.
3. Screw the oil filler cap firmly back in place.
4. Wipe away any spilt chain oil carefully.
NOTE:
• When the chain saw is used for the first time, it may
take up to two minutes for the saw chain oil to begin its
lubricating effect upon the saw mechanism. Run the
saw without load until it does so (see "CHECKS").
• When filling the chain oil for the first time, or refilling the
tank after it has been completely emptied, add oil up to
the bottom edge of the filler neck. The oil delivery may
otherwise be impaired.
• Use the saw chain oil exclusively for Makita/Dolmar
chain saws or equivalent oil available in the market.
• Never use oil including dust and particles or volatile oil.
• When pruning trees, use botanical oil. Mineral oil may
harm trees.
• Before the cutting operation, make sure that the
provided oil tank cap is screwed in place.
CHECKS
Before starting work, carry out the following checks:
Checking the chain tension
WARNING:
• Always withdraw the mains plug before checking the
chain tension, and wear safety gloves.
(For nut models) (Fig. 17)
(For lever models) (Fig. 18)
Make sure the saw chain fits snugly against the lower side
of the bar (see circle).
Check the chain tension frequently, as new chains are
subject to elongation.
Excessively high tension of saw chain may cause
breakage of saw chain, wear of the guide bar and
breakage of the adjusting dial.
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 the saw 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.
