Tips for maintaining maximum battery life
1.
Charge the battery cartridge before completely
discharged. Always stop tool operation and
charge the battery cartridge when you notice
less tool power.
2.
Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3.
Charge the battery cartridge with room tempera-
ture at 10 °C - 40 °C (50 °F - 104 °F). Let a hot bat-
tery cartridge cool down before charging it.
4.
When not using the battery cartridge, remove it
from the tool or the charger.
5.
Charge the battery cartridge if you do not use it
for a long period (more than six months).
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Installing or removing battery cartridge (Fig. 1)
• 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 per-
sonal 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 car-
tridge does not slide in easily, it is not being inserted
correctly.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power to
extend tool and battery life. The tool will automatically
stop during operation if the tool or battery is placed under
one of the following conditions:
• Overload protection
This protection works when the tool is operated in a
manner that causes it to draw an abnormally high
current. In this situation, turn the tool off and stop the
application that caused the tool to become over-
loaded. Then turn the tool on to restart.
• Overheat protection
This protection works when the tool or battery is
overheated. In this situation, let the tool and battery
cool before turning the tool on again.
• Overdischarge protection
This protection works when the remaining battery
capacity gets low. In this situation, remove the bat-
tery from the tool and charge the battery.
Indicating the remaining battery capacity (Fig. 2)
Only for battery cartridges with the indicator
Press the check button on the battery cartridge to indi-
cate the remaining battery capacity. The indicator lamps
light up for a few seconds.
015658
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
• The first (far left) indicator lamp will blink when the bat-
tery protection system works.
Switch action (Fig. 3)
CAUTION:
• Before inserting 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Installing or removing saw chain
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the saw chain.
• Always wear gloves when installing or removing the
saw chain.
• Use only saw chain and guide bar with bar tip designed
for this chain saw (see the Extract from the spare parts
list).
• In order to prevent kickback, do not remove the bar tip
or replace the guide bar with one without a bar tip.
