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. (Fig. 2)
Overdischarge protection (Fig. 3)
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 (Fig. 4)
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 (Fig. 5)
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.
CAUTION:
• 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:
• Should the saw chain not come to a stop within one
second when this test is performed, the saw must not
be used. Consult a DOLMAR specialist repair shop.
Adjusting the chain lubrication (Fig. 6)
You can adjust the oil pump feed rate with the adjusting
screw. The amount of oil can be adjusted using the
universal wrench.
Carabiner (rope attachment point) (Fig. 7)
Carabiner (Rope attachment point) is for use of tool
hanging. Before using carabiner, pull it out and tie it with
a rope.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Removing or installing saw chain (Fig. 8, 9, 10,
11, 12 & 13)
CAUTION:
• Always wear gloves when installing or removing the

• The saw chain and the guide bar are still hot just after
the operation. Let them cool down enough before
carrying out any work on the tool.
To remove the saw chain, perform the following steps:
1. Press and fully open the lever until it stops.
2. Turn the adjusting dial to "–" direction to release the
saw chain tension.

saw.
To install the saw chain, perform the following steps:
6. Make sure the direction of the chain. The arrow
mark on the chain shows the direction of the chain.
7. Fit in one end of the saw chain on the top of the
guide bar and the other end of it around the
sprocket.
8. Rest the guide bar in place on the chain saw.
9. Turn the adjusting dial to "–" direction to slide the
adjusting pin in the direction of arrow.
10. Place the sprocket cover on the chain saw so that
the adjusting pin is positioned in a small hole in the
guide bar.
11. Turn the lever clockwise fully and a quarter turn back
to keep looseness for adjusting chain tension.
12. Turn the adjusting dial, and adjust the chain tension.
13. Turn the lever clockwise to secure the sprocket
