Safety and operating instructions
Operation
WARNING Involuntary start
Involuntary start of the machine may cause injury.
Keep your hands away from the start and stop
►
device until you are ready to start the machine.
►
Learn how the machine is switched off in the event
of an emergency.
►
Stop the machine immediately in all cases of
power supply interruption.
NOTICE Never exceed the maximum flow for the
machine, as this might lead to failure of the drill bit
and damage to the machine.
Preparations before starting
Check the drilling equipment
♦
Check that all of the drilling equipment is in a good
condition.
♦
Inspect the hoses generally for signs of damage.
Check that the drill bit is in a good condition and
♦
has the correct diameter for the size of the core
drill.
Clean all safety labels. Replace any that are
♦
missing or cannot be read.
Ensure that the hydraulic couplings are clean and
♦
fully serviceable.
Ensure that the fittings are tight and leak-proof.
♦
Always use the core drill with a front handle
♦
mounted, to absorb the reaction torque.
Screw the drill bit into the nose end drive of the
♦
shaft and tighten by means of the spanner flats
provided.
Check that the core drill is not blocked and that
♦
water flows through without obstruction.
Ensure that the power source to be used is
♦
compatible with the machine model, see the
"Technical data".
Atlas Copco recommends using an LFD oil flow
♦
divider, if the flow from the power source can
exceed the maximum allowed oil flow.

Start and stop
♦
Start the machine by pressing the trigger while
firmly holding the handle. By gradually applying
pressure on the trigger, the speed may be reduced
to obtain a soft start.
♦
Stop the machine by releasing the trigger. The
trigger returns automatically to the stop position.
When the work is done, stop the power source.
Disconnect the hoses and fit the protective caps
to the quick-release couplings.
Operating
Before drilling
1. Connect the hydraulic hoses.
2. Connect the water hose to the water tap.
3. Screw the handle lightly into the handle ring and
place the handle in a position that is comfortable
for the operator.
4. Lock the handle ring in this position by tightening
the handle to grip the bearing housing. Ensure
that the handle remains locked throughout the
drilling operation.
5. Start the power source.
6. Activate the water supply.
Starting a cut
Stand steady and make sure that your feet and
♦
hands are at a safe distance from the drill bit.
To start the drilling it is advisable to either turn the
♦
core drill to one side in order to obtain an initial
groove and then slowly return to horizontal or
vertical position as soon as the drill bit has
engaged in the material to be drilled, or provide a
guide to stop the drill bit skidding across the
surface of the material to be drilled.
When taking a break
♦
During all breaks you must place the machine in
such a way that there is no risk for it to be
unintentionally started. Make sure to place the
machine on the ground, so that it can not fall.
♦
In the event of a longer break or when leaving the
workplace: Switch off the power supply and then
bleed the machine by activating the start and stop
device.
