Service
NO USER SERVICE -
ABLE PARTS INSIDE.
Preventive maintenance performed by un -
au thorized personnel may result in
misplacing of internal wires and
components which could cause serious
hazard.
We recom mend that all tool service
be performed by a Dremel Service Center.
SERVICE MEN: Disconnect tool and/or
charger from power source before servicing.
BATTERIES
Be alert for battery packs that are nearing
their end of life.
If you notice decreased
tool performance or significantly shorter
running time between charges then it is time
to replace the battery pack. Failure to do so
can cause the tool to operate improperly or
damage the charger.
Cleaning
To avoid accidents,
always disconnect the
tool and/or charger from the power supply
before cleaning.
The tool may be cleaned
most effectively with com pressed dry air.
Always wear safety goggles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through opening.
Certain cleaning agents
and solvents damage
plastic parts.
Some of these are: gasoline,
car bon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
Maintenance
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used.
This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE:
The smaller the gauge number, the
heav i er the cord.

Third, if a flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly together.
TEMPERATURE DEPENDENT OVERLOAD
PROTECTION
When using as intended for, the power tool
cannot be subject to overload. When the load
is too high or the allowable battery temperature
is exceeded, the electronic control switches off
the power tool until the temperature is in the
optimum temperature range again.
PROTECTION AGAINST DEEP
DISCHARGING
The lithium-ion battery is protected against
deep discharging by the “Electronic Cell
Protection (ECP)”. When the battery is empty,
the machine is switched off by means of a
protective circuit: The tool no longer rotates.
