FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
Fig.1
CAUTION:
Always switch off the tool before installing or
•
removing of the battery cartridge.
Hold the tool and the battery cartridge firmly
•
when installing or removing battery cartridge.
Failure to hold the tool and the battery cartridge
firmly may cause them to slip off your hands and
result in damage to the tool and battery cartridge
and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
CAUTION:
Always install the battery cartridge fully until the
•
red indicator cannot be seen. If not, it may
accidentally fall out of the tool, causing injury to
you or someone around you.
Do not install the battery cartridge forcibly. If the
•
cartridge does not slide in easily, it is not being
inserted correctly.
NOTE:
The tool does not work with only one battery
•
cartridge.
Tool / battery protection system
The tool is equipped with a tool/battery protection
system. This system automatically cuts off power to the
motor to extend tool and battery life.
The tool will automatically stop during operation if the
tool or battery are placed under one of the following
conditions. In some conditions, the indicators light up.
Overload protection
When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops without any indication. In this situation, turn the
tool off and stop the application that caused the tool to
become overloaded. Then turn the tool on to restart.
Overheat protection for battery / tool
When the battery / tool is overheated, the tool stops
automatically without any indication. The tool does not
start even if pulling the switch trigger. In this situation,
let the battery / tool cool before turning the tool on again.
NOTE:
The battery overheat protection works only with a
battery cartridge with a star marking.

When the remaining battery capacity gets low, the
battery indicator blinks on the applicable battery side.
By further use, the tool stops and the battery indicator
lights up about 10 seconds. In this situation, charge the
battery cartridge.
Switch action
CAUTION:
Before installing the battery cartridge into 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.

Checking the chain brake

NOTE:
If the chain saw fails to start, the chain brake must
•
be released. Pull the front hand guard backwards
firmly until you feel it engage.
Hold the chain saw with both hands when switching it
on. Hold the top handle with your right hand, the front
handle with your left. The bar and the chain must not be
in contact with any object.
First press the lock-off button, then the switch trigger.
The saw chain starts immediately.

Press the front hand guard forwards using the back of
your hand. The saw chain must come to an immediate
standstill.

Should the saw chain not stop immediately when
•
this test is performed, the saw may not be used
under any circumstances. Consult a DOLMAR
specialist repair shop.
Checking the run-down brake
Switch on the chain saw.
Release the switch trigger completely. The saw chain
must come to a standstill within one second.
CAUTION:

•
one second when this test is performed, the saw
must not be used. Consult a DOLMAR specialist
repair shop.
