STARTING AND STOPPING
Before starting
•
Prevent unintentional starting. Ensure the switch is in the
OFF-position before connecting to power source and/or
battery pack, picking up or carrying the tool. Carrying
power tools with your finger on the switch or energising
power tools that have the switch on invites accidents.
•
Remove any adjusting key or wrench before turning the
power tool on. A wrench or a key left attached to a rotating
part of the power tool may result in personal injury.
Make sure that:
•
The switch is undamaged. If not, the switch must be
replaced by an authorised repairman.
•
The machine and its equipment are correctly installed:
- The drill is secured properly.
- The stand is firmly attached.
- Secure the machine on the stand using a suitable method.
•
Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
•
Water cooling is connected to the machine.
Drilling in the ceiling
Starting
•
Turn on the water cooling.
•
Press in the switch fully.
NOTE!
The machine uses a push-button switch. Hold the ON button
down for a moment before releasing. This will allow the relay
to hold. If the power supply is interrupted, the switch will
automatically switch off.
•
Allow the machine to come up to full speed before
contacting workpiece.
•
Start to feed the drill bit with the help of the feed handle.
Use very light pressure for the first few millimeters to keep
the bit from wandering. Then proceed normally. It’s not
necessary to use excessive force. This will only slow
drilling and overload the motor.
Use especially light pressure when you encounter steel
reinforcing rods. High pressure against reinforcing rods
will trip the circuit breaker. If the circuit breaker trips,
remove the bt from contact with the workpiece before
resetting.
Stopping
Shut down the machine by pressing the power switch.
Cooling
Run the machine unloaded for a minute or two to cool the
motor.
This will also blow dust and dirt out of the motor, ensuring
longer life for the machine.
!
WARNING! Note the following before
starting:
The machine should be connected to an
earthed outlet socket.
Check that the mains voltage corresponds
with that stated on the rating plate on the
machine. Keep people and animals well
away from the working area.
!
WARNING! Before drilling, check that all
locking screws are tightened well.
Serious accidents can occur if the concrete
core remains in the drill when backing out
the drill motor/drill from the floor, wall or
ceiling.
!
WARNING! The vacuum plate must never be
used for ceiling drilling.
Use a water collector to avoid water
penetrating into the machine. The machine
must be covered with plastic or the like in
order to prevent water penetrating into the
machine, but do not cover the air intakes
and air outlets.
Check that no one on the floor below can be
injured by falling concrete cores.
!
WARNING! The drill bit continues to rotate
for a while after the motor has been switched
off. Do not stop the drill bit with your hands.
Personal injuries can occur.
