Drill bit
Choosing drill bit
A correct drill bit is a condition for good operation.
To avoid unnecessary machine damage, it is
important to choose drill bits with a high quality.
Fitting and removing the drill bit
Smaller diameter drill bits are fitted directly into the
machine drive shaft (1/2 inch BSP). For larger
diameter drill bits, use an 1/2 inch BSP male x
1.1/4 inch UNC male drive adaptor, which is
included with the machine.
To prevent an accidental start:
1)
Switch off the power supply and
disconnect the machine from the power
source.
2)
Screw the drill bit into the machine.
3)
Lock the spindle using a spanner and
tighten the drill bit.
4)
Bleed the machine by pressing the start
and stop device.
NOTICE
Never cool a hot insertion tool in water; it
can result in brittleness and early failure.
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
o
Check that all of the drilling equipment is in a
good condition.
o
Inspect the hoses generally for signs of damage.
o
Check that the drill bit is in a good condition and
has the correct diameter for the size of the core
drill.
o
Clean all safety labels. Replace any that are
missing or cannot be read.
o
Ensure that the hydraulic couplings are clean
and fully serviceable.
o
Ensure that the fittings are tight and leak-proof.
o
Always use the core drill with a front handle
mounted, to absorb the reaction torque.
o
Screw the drill bit into the nose end drive of the
shaft and tighten by means of a spanner.
o
Check that the core drill is not blocked and that
water flows through without obstruction.
o
Ensure that the power source to be used is
compatible with the machine model, see the
‘Technical data’.
o
Xcalibre Equipment recommends using an oil
flow divider, if the flow from the power source
can exceed the maximum allowed oil flow.
Start and stop
o
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.
o
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
o
Stand steady and make sure that your feet and
hands are at a safe distance from the drill bit.
o
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.
