hidden wiring or its own cord. Cutting
accessory contacting a "live" wire may make
exposed metal parts of the tool "live" and
could give the operator an electric shock.
•
Use auxiliary handles supplied with the
tool. Loss of control can cause personal
injury.
•
Wear safety goggles or other eye
protection. Drilling operations cause chips to
fly. Flying particles can cause permanent eye
damage.
•
Bits, tools and drilling area get hot during
operation. Wear gloves when touching
them.
•
Use the diamond drill under constant
supervision.
•
Make sure not to cut through electric mains,
gas or water pipes. Use detection systems
prior to drilling.
•
Make sure the cutting accessory is fitted
properly.
•
Check all screws and tighten securely before
you use the machine.
•
When drilling downward, make sure the core
can drop safely without injuring someone
standing beneath.
•
Drilling is only allowed downward, horizontally
and overhead (upward). If performing
overhead (upward) drilling, water cooling use
is NOT PERMITTED.
•
When drilling handheld, always use the side
handle and hold the machine firmly with both
hands.
•
Make sure to stand on a stable surface and
keep body balance at all times for better
control of reaction torque.
•
Inspect the machine before every use. Do not
use the machine if there are any defectives
on the mains plug, power cord, trigger switch
or any part of the housing. Have the machine
repaired by an authorized repair agent.
•
Do not use the machine in a damp or wet
location.
•
Switch off the machine immediately if there is
any leak of water.
•
After interrupting the cut, do not switch on
until the core bit can rotate freely.
•
Always trigger off the switch to prevent the
machine from accidentally self starting.
Note this procedure especially after the
power supply is interrupted or the plug is
disconnected from the power outlet.
•
Mounting the tool onto a stand is
recommended to increase the user comfort
and reduce the risk of injuries.
•
In case of jammed core bit disconnect the
machine from the power supply, remove
30
the reason for the jam before turning on the
machine again.
DRY DRILLING
•
Dry drilling is suitable for masonry
(bricks, breeze blocks).
•
Always use a suitable dust extractor.
•
Always use core bits designed for dry drilling.
•
Do not use the machine handheld with core
bits larger than 100 mm.
•
Always mount the drill on a stand when
drilling holes larger than 100 mm.
•
Wear a dust mask when performing dry cuts.
WET DRILLING
•
Wet drilling is suitable for stone and concrete.
•
Always use a water cooling device and a
water collection system.
•
Always use core bits designed for wet drilling.
•
The maximum water pressure is 3 bar. Use
a pressure relieve valve in case of a higher
water pressure.
•
Use only pure tap water for cooling
purposes.
•
Prevent water from entering the motor or
other electrical components. Make sure the
PRCD is not in contact with water.
Safe Operation for Stationary Stands
•
A machine incorrectly assembled may
cause a hazardous situation. Carefully fix the
machine into the drill stand and check that
the drill stand holder is secured.
•
Fixing the drill stand with vacuum device can
lead to dangerous situations.
•
Check the surface where the drill stand shall
be fixed. surface such as irregular (rough) can
significantly reduce the effectiveness of the
suction system. Coated or laminated surface
can be pulled off during work.
•
The minimum vacuum level shall not be lower
than 600mbar. Periodically control this value
on the pressure gauge.
•
Do not use drill core bits with a diameter
greater than 202 mm at this application.
Additional Instructions for Use in
Stationary Position
SAFETY PRECAUTIONS
•
Hazardous situation due to broken parts.
Always check the core bits before using.
Never use deformed or damaged drill core
bits.
•
Use of non-recommended cutting tools,
which can lead to injuries due to the loss
of control. Use only core bits which are
designed for this tool and consider the
