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.
