Intended Use
The machine is intended for cutting wood length-
ways and crossways in straight lines and at mitred
angles of up to 45° on a firm surface.
Observe the recommendations for saw blades.
The user is responsible for damage caused by usage
other than intended for.
Before Putting into Operation
The batteries are partially charged and delivered in
idle state. The battery must be activated before using
for the first time. For this, place the battery onto the
charger for a short time. The LED 16 on the battery
indicates the charge condition (see main figure).
When the battery is not used for longer periods, it
switches to the idle state. In order to use the battery
again, it must be reactivated.
When the battery is completely discharged, it
switches off automatically (deep discharging not
possible). When the power tool is switched on none-
theless, the battery delivers only brief current pulses.
The power tool "flickers" as an indication that the
battery must be charged.
As a general rule: Should the power tool not be op-
erative after inserting the battery, place the battery
onto the charger. The indicators on the battery and
the charger then provide information about the bat-
tery condition (see main figure).
At low temperatures, further operation is possible
with reduced power output. The battery switches off
automatically below -18 °C.
Battery Charging (see Main Figure)
A battery that is new or has not been used for a longer
period does not develop its full capacity until after ap-
proximately 2 – 3 charging/discharging cycles.
To remove the battery 7, press the unlocking but-
tons 15 and pull out the battery toward the rear. Do
not exert any force.
Please refer to the enclosed "Battery Charger" in-
structions for the operation of the battery charger as
well as for a description of the charging process.
The battery is equipped with an NTC temperature
control which allows charging only within a temper-
ature range of between +5 °C and +40 °C. A long
battery service life is achieved in this manner.
A significantly reduced working period after charg-
ing indicates that the batteries are used and must be
replaced.
Observe the notes on environmental protection.
Charge-control Indicator (see Main Figure)
The battery 7 is fitted with a charge-control indica-
tor 16.
By pressing the button 17, the battery charge can
also be checked when the battery has been re-
moved, or when the machine is at a standstill (ma-
chine must be switched off for at least 1 minute). Af-
ter approx. 4 seconds the battery charge display au-
tomatically turns off.
When the first display element begins to flash
(0 – 10 %) the battery is almost empty and must be
recharged.
Adjusting the Cutting Depth/
Bevel Angle
Before any work on the machine itself, remove
the battery.
Adjusting the Cutting Depth (see Figure A)
– Push lever 18 downward.
– Move handle 6 up or down to adjust the correct
cutting depth.
– Check the cutting depth.
– Tighten lever 18.
