b) Changing tools
- To insert or remove a tool with CENTROTEC
shaft, pull the green release ring (2.10)
back. On inserting the tool, turn it until its
hex shank arbour (2.9) locks in place in the
hexagonal shank of the drill spindle, and
push the tool into the toolholder as far as
it will go.
3.5 Tool holding fi xture in the drill
spindle
Bits can be fi tted directly in the hexagon
socket holder of the drill spindle (2.5) to
make the machine lighter and shorter.
4 Charge battery pack
To load the battery pack, push it into the
holder (3.1) on the charger up to the stop.
Perform this in reverse to remove the battery
pack from the charger. The battery type used
(NiCd or NiMH) is detected automatically.
Charging is controlled by a microprocessor.
If a warm NiMH battery pack (>37° C) is
inserted, charging will only be carried out
at a lower charge current. In this case, the
charging time is extended.
The LED (3.2) indicates the respective
charging state of the charger.
LED yellow – steady:
Charger is ready for use.
LED green – fl ashing:
Battery pack being charged.
LED green – steady:
Battery pack fully charged, conservation
charge on.
LED red – fl ashing:
General malfunction, e. g. full contact not
being made, short-circuit, battery pack
faulty.
LED red – steady:
Temperature of battery pack is outside
permissible limit.
It is essential that you read
the instructions in the Chapter
„Working instructions - Mainte-
nance - Care“.
5 Working with the machine
5.1 Initial operation
Turn on by pressing button (1.3). Depending
on the pressure exerted on the button, the
adjustment of running speed can be varied
infi nitely. Turn off by releasing the button
(1.3).
After releasing the button, the chuck is
stopped and therefore, after-running of the
equipment is prevented.
5.2 Bit storage well
You can insert several bits or bit extensions
into the bit magazine (1.2) with magnetic
holder.
5.3 Warning signal
With the following operational statuses, the
machine sounds an acoustic warning signal
and switches off:
Peep at regular intervals
- Battery empty
Triple peep at regular intervals
- Excessive load (torque)
- Machine too warm.
6 lnstructions on application -
maintenance - care
Please pay attention to the fol-
lowing instructions. Otherwise
there is a risk of damage to the
tool, charger or battery pack.
- Repairs may only be performed by author-
ised technicians. LC 45 charging device:
Even after disconnection from the mains,
there is still a high capacitor voltage on the
power output component on the inside of
the device.
- Keep the air vents of the electronic equip-
ment and the charger clean to guarantee
the air circulation for cooling.
- No metal objects (metal chips) should
enter the charger at the contact points as
well as through the cooling slits into the
equipment (danger of short circuit).
- Only use original Festool battery packs.
Do not use spent and recycled battery
packs. The user shall be liable for dam-
ages if Festool original battery packs are
not used.
- Keep the connection contacts of electronic
equipment, charger and battery pack
clean.
- By keeping the battery pack in a ready for
use charger, the battery pack will be kept
in a state of readiness by fl oat charging
conservation.
- Do not keep discharged battery pack
(maximum one month) attached to charger
whenever charger is detached from the
