•
Depress the on/off switch (1). It regulates the
speed of the appliance by transmitting power
to the switch.
•
Release the on/off switch (1) to halt the drill
chuck immediately which will no longer run
on.
•
Move the direction reversing switch (5) to the
centre in order to lock the appliance in its
disabled state.
Only lay down the appliance when it has stopped
running completely. Do not place it on a dusty
surface as particles of dust could get into the
mechanism.
Charging the battery
•
The included battery is delivered in partly
charged condition.
•
Only use the battery charger in a temperature
range between + 5 °C to + 40 ºC.
•
Only use the battery charger in dry, ventilated
rooms.
Charging
Fig. E
•
Place the battery holder on a flat table and put
the battery in the battery holder. Pay attention
to + and - pole markings.
•
Put the adapter plug of the net adapter in the
connector on the side of the battery holder.
•
Put the net adapter in the socket.
•
The red charging lamp on the battery holder
will illuminate indicating the battery is being
charged.
•
The charging process of a fully discharged
battery will take approximately 5 hours the
first time and afterwards approximately 3
hours.
After the charging time the red light will
not switch off automatically! Remove
the battery within 5 hours from the
charger. If the battery is not removed
from the charger after the charging
period it may become overheated.
Discharging the battery
Not only charging batteries is important,
discharging is of equal importance or
even greater importance.
•
When the battery is charged the cordless drill
has to be used until you start noticing that the
power of the drill is diminishing and that the
maximum rotational speed is not reached.
•
The battery is almost discharged now. Only
now you can start charging the battery.
•
Charging the battery while it is still charged for
say one-third of capacity, the so-called
'memory effect' can occur. Since during
charging only the discharged part of the
battery capacity of the battery is being
charged now, the battery can start
crystallizing in the one-third that is still
charged. This part of the battery capacity can
never be used afterwards.
•
Do not discharge the battery to the minimum.
As soon as you notice that the power or the
maxi mum rotational speed is diminishing, you
have to charge the battery. When you proceed
using the drill and the battery becomes fully
discharged, the so-called 'switch of poles
effect' can occur. The polarity of the battery
poles will be switched: the '+'will become '-'
and the '-' will become the '+'. Once this has
occurred the polarity will remain switched
during loading and this will damage the
battery irreparable.
When the cordless drill is not being
used over a longer period of time, the
battery has to be charged fully first. The
battery has to be stored in charged
condition.
5. Service & maintenance
Make sure that the machine is not live
when carrying out maintenance work on
the motor.
These machines have been designed to operate
over a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper machine care and regular
cleaning.
Cleaning
Keep the ventilation slots of the machine clean to
prevent overheating of the engine. Regularly
clean the machine housing with a soft cloth,
preferably after each use. Keep the ventilation
slots free from dust and dirt. If the dirt does not
come off use a soft cloth moistened with soapy
water. Never use solvents such as petrol, alcohol,
