5. Safety precautions
CAUTION: The following basic safety precautions must
always be observed when using electric machines in
order to avoid the risk of electric shock, injury or fire.
Read all of these instructions before using this machine
and keep this list of safety precautions for future reference.
5.1 The necessary safety precautions at the workplace
● Approval must be obtained from the site engineer or
architect prior to beginning drilling work. Drilling work
on buildings and other structures may influence the
statics of the structure, especially when steel reinforcing bars or load-bearing components are cut through.
● Ensure that the workplace is well lit.
● Ensure that the workplace is well ventilated.
● Keep the workplace tidy. Objects which could cause
injury should be removed from the working area. Untidiness at the workplace can lead to accidents.
● When drilling through-holes, the area below the ceil-
ing, floor or behind the wall where the drilling is taking place must be secured as the drilled-out core may
fall out.
● Use clamps or a vice to secure the workpiece. The
workpiece is thus held more securely than by hand and
both hands remain free to operate the machine.
● Use protective equipment. Wear eye protection.
● Wear breathing protection if the work creates dust.
● Wear suitable working clothing. Do not wear loose
clothing, loose long hair or jewelry as it can become
caught up in moving parts. Wear suitable headgear if
you have long hair.
● It is recommended that rubber gloves and non-slip
shoes are worn when working outdoors.
● Keep children and other persons away from the work-
ing area.
● Do not allow other persons to tamper with the machine
or the supply cord.
● Avoid unfavorable body positions. Work from a secure
stance and stay in balance at all times.
● To avoid tripping and falling when working, always lead
the supply cord, extension cord and water hose away
to the rear.
● Keep the supply cord, extension cord, water hose and
vacuum hose away form rotating parts of the machine.
● CAUTION: Before beginning drilling, check that there
are no live electric cables located in the area where
the hole is to be made.
● Concealed electric cables or gas and water pipes pre-
sent a serious hazard if damaged while you are working. Accordingly, check the area in which you are working beforehand (e.g. using a metal detector). External
metal parts of the machine may become live, for example, when an electric cable is drilled into inadvertently.
● Do not work from a ladder.
19
en
5.2 General safety precautions
● Use the right machine for the job. Do not use the
machine for purposes for which it was not intended.
Use the machine only as directed and when it is in
faultless condition.
● Use only the original accessories or ancillary equip-
ment listed in the operating instructions. Use of other insert tools or accessories may present a risk of
personal injury.
● Take the influences of the surrounding area into account.
Do not expose the machine to rain or snow and do
not use it in damp or wet conditions. Do not use the
machine where there is a risk of fire or explosion.
● Keep the grips dry, clean and free from oil and grease.
● Do not overload the machine. It will work more effi-
ciently and more safely within its intended performance range. The side handle must be fitted for all
types of work.
● Never leave the machine unattended.
● When not in use, the machine must be stored in a dry
place, locked up or out of reach of children.
● Avoid unintentional starting. Check that the on / off
switch is in the "off” position before plugging the supply cord into the electric socket.
● Unplug the machine from the electric supply when it
is not in use, during pauses between work, before
maintenance and when changing core bits.
● Check the PRCD each time before use.
● Take care of your core bits. You will be able to work
more efficiently and more safely if the core bits are
kept sharp and clean.
● Check the machine for possible damage. Protective
devices and any parts that may have suffered slight
damage should be checked for correct operation and
functionality before further use. Check that moving
parts function correctly without sticking and that no
parts are damaged. All parts must be fitted correctly
and fulfill all conditions necessary for correct operation of the machine. Damaged safety devices or other damaged parts must be replaced or repaired properly by an authorized repair workshop unless otherwise indicated in the operating instructions.
● Avoid skin contact with drilling slurry.
● Wear respiratory protection when the work creates
dust, e.g. during dry drilling. Connect a vacuum cleaner to the drilling system. Drilling into materials that
present a health hazard (e.g. asbestos) is not permissible.
5.2.1 Mechanical hazards
● Follow the instructions concerning care and mainte-
nance.
● Check that the insert tools used are compatible with
the chuck system and that they are secured in the
chuck correctly.
● Make sure that the machine is correctly and securely
attached to the drill stand.
● Do not touch rotating parts.
● Make sure that all clamping screws are tightened cor-
rectly.
● After detaching the column extension, the end cap
(with built-in, safety-relevant end stop function) must
be refitted to the drill stand.
5.2.2 Electrical hazards
● Protect yourself against electric shock. Avoid body
contact with earthed / grounded objects, e.g. pipes,
radiators, cookers and fridges.
● Check the condition of the supply cord and its plug
connections and have it replaced by a qualified electrician if damage is found. Check the condition of the
extension cord and replace it if damage is found.
● Check the condition of the machine and its acces-
sories. Do not operate the machine or its accessories
if damage is found, if the machine is incomplete or if
its controls cannot be operated faultlessly.
● Do not touch the supply cord in the event of it suffer-
ing damage while working. Disconnect the supply cord
plug from the socket.
● Damaged or faulty switches must be replaced at a Hilti
service center. Do not use the machine if it cannot be
switched on and off correctly.
● Have the machine repaired only by a trained electri-
cal specialist (Hilti service center) using original Hilti
spare parts. Failure to observe this point may result
in risk of accident to the user.
● Do not use the supply cord for purposes for which it
is not intended. Never carry the machine by the supply cord and never pull the plug out of the socket by
pulling the supply cord.
● Do not expose the supply cord to heat, oil or sharp
edges.
● When working outdoors, use only extension cords
that are approved and correspondingly marked for
this application.
● In the event of a power failure, switch the machine off
and unplug the supply cord.
● Avoid using extension cords with multiple sockets
and the simultaneous use of several machines connected to one extension cord.
● Never operate the machine when it is dirty or wet. Dust
(especially dust from conductive materials) or dampness adhering to the surface of the machine may,
under unfavorable conditions, cause an electric shock
to be received. Dirty or dusty machines should thus
be checked at a Hilti service center at regular intervals, especially used frequently for working on conductive materials.

Disconnect the supply cord plug from the socket.
Care of insert tools and metal parts
Remove any dirt adhering to the core bits and protect
their surfaces from corrosion by rubbing them with an
oily cloth from time to time.
8.1 Care of the machine
The outer casing of the drive unit is made from impactresistant plastic.
Never operate the drive unit when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the drive unit. Clean the outside of the drive
unit at regular intervals with a cloth. Do not use a spray,
steam pressure cleaning equipment or running water
for cleaning. This may negatively affect the electrical
safety of the drive unit.
8.2 Maintenance
Check all external parts of the machine for damage at
regular intervals and check that all controls operate faultlessly. Do not operate the machine if parts are damaged
or when the controls do not function faultlessly. If necessary, the machine should be repaired at a Hilti repair
center.
Repairs to the electrical section of the machine may be
carried out only by trained electrical specialists.
8.3 Replacing the carbon brushes
The indicator lamp with the wrench symbol lights when
the carbon brushes require to be replaced.
Failure to observe the following instructions may present a possibility of coming into contact with a dangerous high voltage. The machine may be operated, serviced and repaired only by authorized, trained personnel. This personnel must be informed of any special hazards that may be encountered.
1. Disconnect the drive unit from the electric supply.
2. Remove the covers from the right and left sides of the
drive unit.
3. Remove the used carbon brushes from the drive unit.
Note how the brushes are fitted.
4. Fit the new carbon brushes exactly as the old carbon brushes (Spare part no.: 100–127 V: 279526;
220–240 V: 280097).

adjusted by way of 4 eccentrically-mounted rollers.
The 4 rollers shown in the illustration can be adjusted.
First remove the drive unit from the drill stand and run
the carriage up to the top of the column by turning the
hand wheel. The 4 rollers can then be adjusted as follows:
1. Use a 5 mm AF hex. socket wrench to unscrew the
locking screw slightly (do not remove the screw).
2. Use a 19 mm AF open-end wrench to turn the eccentric axle, thus pushing the roller slightly toward the
column.
3. Tighten the locking screw.

10. Disposal
Most of the materials from which Hilti tools or machines are manufactured can be recycled. The materials must
be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back your old machines or tools for recycling. Please ask your Hilti customer service department or Hilti
sales representative for further information.
Disposal of drilling slurry
With regard to environmental aspects, allowing drilling slurry to flow directly into rivers, lakes or the sewerage
system without suitable pre-treatment is problematical. Ask the local authorities for information about applicable regulations.
We recommend the following pre-treatment:
Collect the drilling slurry (e.g. use a wet-type industrial vacuum cleaner).
Allow the slurry to settle and dispose of the solid material at a construction waste disposal site (the addition of
a flocculent may accelerate the settling process).
Water from the drilling slurry (alkaline, ph value > 7) should be neutralized by adding an acidic neutralizing agent
or large quantity of water before it is allowed to flow into the sewerage system.
Only for EU countries
Do not dispose of electric tools together with household waste material!
In observance of European Directive 2002/96/EC on waste electrical and electronic equipment
and its implementation in accordance with national law, electric tools that have reached the
end of their life must be collected separately and returned to an environmentally compatible
recycling facility.
