2. Preparations for Use
2.1. Electrical connection
WARNING WARNING
Mains voltage present! Before connecting the REMS rapid charger, check whether the voltage given on the
rating plate corresponds to the mains voltage. On building sites, in a wet environment, indoors and outdoors
or under similar installation conditions, only operate the electrical device on the mains with a fault current
protection switch (RCD) which interrupts the power supply as soon as the leakage current to earth exceeds
30 mA for 200 ms.
Rechargeable batteries (8)
Total discharging by undervoltage
The Li-Ion batteries may not drop below a minimum voltage because otherwise the battery could be damaged
by "total discharge". The cells of the REMS Li-Ion battery are delivered pre-charged to approx. 40 %. There-
fore the Li-Ion batteries must be charged before use and recharged regularly. Failure to observe this regula-
tion of the cell manufacturer can lead to damage to the Li-Ion battery by total discharging.
Total discharging due to storage
If a relatively low charged Li-Ion battery is stored, self discharging can lead to total discharge damage of the
battery after longer storage. Li-Ion batteries must therefore be charged before storing and recharged every
six months at the latest and charged again before use.
NOTICE NOTICE
Charge the battery before use. Recharge Li-Ion batteries regularly to avoid their total discharge. The
rechargeable battery will be damaged by total discharge.
Only use REMS rapid charger (accessories Art.No. 571575, 571585) for charging. New Li-Ion batteries and
Li-Ion batteries which have not been used for a long time only reach full capacity after several charges.
Rapid charger (accessories Art.No. 571575, 571585)
The left control lamp lights up and remains green when the mains plug is plugged in. If a battery is inserted
in the rapid charger, the green control lamp fl ashes to indicate that the battery is charging. The green light
stops fl ashing and remains on to signal that the battery is fully charged. If the red control lamp fl ashes, the
battery is defective. If the red control lamp comes on and remains on, this indicates that the temperature of
the rapid charger and / or the battery is outside the permissible operating range of 0°C to +40°C.
NOTICE
The rapid chargers are not suitable for outdoor use.
Power supply
The power supply unit is for operating the power tools on the mains instead of with the battery. The power
supply unit is equipped with overvoltage and temperature protection. The operating state is indicated by
a LED. A lit LED indicates that the device is ready for operation. If the LED goes out or fl ashes, this indi-
cates an overcurrent or impermissible temperature. The drive unit cannot be used during this time. After
a dwell time, the LED lights again and work can be continued.
NOTICE
The power supply unit is not suitable for outdoor use.
2.2. Setting the speed
NOTICE NOTICE
Only switch the preselection lever for the speed range (3) when the power tool is out of operation.
The power tool has two speeds which are set by a mechanical gear. Set the speed range preselection lever
(3) to "1" for low speed. Set the speed range preselection lever (3) to "2" for high speed. The "1" speed is
used preferably for drilling large diameters, removing burr and turning in/loosening screws. The "2" speed is
used preferably for drilling small diameters. If the speed range preselection lever (3) cannot be turned up to
the stop, turn the quick-clamping chuck slightly by hand.
