DESIGN AND APPLICATION
The electric hammer is a hand-held power tool with class II
insulation. The device is powered by a single-phase commutator
motor. The hammer can be used for drilling holes in non-hammer
mode, hammer mode or channel drilling, as well as for surface
treatment in materials such as concrete, stone, brick, etc.
Areas of application include renovation and construction work, as
well as all types of DIY work.
Do not use the power tool for purposes other than those for which it is
intended.
PREPARATION FOR WORK
INSTALLING THE ADDITIONAL HANDLE
For safety reasons, always use the auxiliary handle (8) when
operating the hammer drill. It can be attached in any position.
• Loosen the handle collar locking knob (8) by turning it counterclockwise.
• Slide the handle collar onto the cylindrical part of the hammer housing.
• Rotate it to the most convenient position.
• Tighten the locking knob clockwise to secure the handle (8).
INSTALLING THE DRILLING DEPTH LIMITER STRIP
• The limiter (9) is used to set the depth of the drill bit in the material.
• Loosen the wing nut on the flange of the auxiliary handle (8).
• Insert the stop bar (9) into the hole in the auxiliary handle flange.
• Set the desired drilling depth.
• Tighten the wing nut.
INSTALLATION AND REPLACEMENT OF WORK TOOLS
• The hammer is designed to work with working tools with SDS-PLUS
shanks.
• Clean the hammer and working tools before starting. Apply a thin layer
of grease using a grease gun.
• onto the working tool shank. This will increase the service life of the
device.
Disconnect the power tool from the power supply.
• Rest the hammer on a workbench.
• Grasp the mounting sleeve (2) of the SDS chuck (1) and pull it
backwards, overcoming the spring resistance.
• Insert the working tool shank into the chuck, pushing it in as far as it
will go (you may need to rotate the working tool until it is in the correct
position) (Fig. A).
• Release the clamping sleeve (2) to finally secure the tool.
• The working tool is correctly seated if it cannot be removed without
pulling back the chuck sleeve.
• If the sleeve does not return fully to its original position, remove the
working tool and repeat the entire operation.
High hammer efficiency can only be achieved if sharp and
undamaged working tools are used.
REMOVING THE WORK TOOL
Immediately after use, the working tools may be hot. Avoid direct
contact with them and wear suitable protective gloves. Clean the working
tools after removal.
Disconnect the power tool from the power supply.
• Pull back and hold the clamping sleeve (2).
• With your other hand, pull the working tool forward.
OVERLOAD CLUTCH
• The hammer is equipped with an internally mounted overload clutch.
The hammer spindle stops as soon as the working tool jams, which
could cause the power tool to overload.
USE OF THE DUST GUARD
• The dust cover is a round rubber moulding with a suitable shape. It is
placed on the drill bit to catch dust when drilling, e.g. in the ceiling.
Place the cover on the drill bit, move the drill bit to the surface of the
material and slide the cover along the drill bit until it touches the
surface of the material. As the drill bit penetrates the material, the
cover will slide along the drill bit, collecting the accumulated dust. The
cover should be emptied from time to time.
Always wear safety glasses or goggles, especially when drilling above
the operator's head.
OPERATION / SETTINGS
TURNING ON/OFF
The mains voltage must correspond to the voltage specified on the hammer's
rating plate.
• Switching on - press the switch button (5) and hold it in this position
(Fig. B).
• Switching off - release the pressure on the switch button (5).
OPERATING MODE SWITCHES
• The electric hammer is equipped with two operating mode switches. The
impact mode switch (6) (Fig. D) and the switch
• drilling mode (3) (Fig. E). Depending on their setting, you can
perform drilling without hammer action, drilling with hammer action,
or chiselling. Drilling with hammer action and chiselling require little
pressure on the hammer. Excessive pressure would cause excessive
strain on the motor. The technical condition of the working tools must
be checked regularly. If necessary, the working tools must be
sharpened or replaced.
• The correct setting of the switches for a given function is shown in Fig. F.
• Drilling without hammer action - pos. I Drilling with hammer action - pos.
II Chiselling - pos. III
• Before changing the position of the drilling mode switch (3), press the
lock button (Fig. G). Do not attempt to change the position of the
operating mode switches while the hammer motor is running. Doing so
could result in serious damage to the hammer.
DRILLING HOLES
• When starting work with the intention of drilling a large-diameter
hole, it is recommended to start by drilling a smaller hole and then
reaming it to the desired size. This will prevent the hammer from
overloading.
• When drilling deep holes, drill gradually, at shallower depths,
withdrawing the drill bit from the hole to allow chips or dust to be
removed from the hole.
• If the drill bit jams during drilling, the overload clutch will activate. Switch
off the hammer immediately to prevent damage. Remove the
jammed drill bit from the hole.
• Keep the hammer in line with the hole being drilled. Ideally, the drill bit
should be positioned at a right angle to the surface of the material being
worked on. If the angle is not perpendicular, the drill bit may jam or break
in the hole during operation, causing injury to the user.
Prolonged drilling at low spindle speeds may cause the motor to
overheat. Take regular breaks during operation. Be careful not to cover
the holes in the housing that are used to ventilate the hammer motor.
HAMMER DRILLING
• Select the appropriate operating mode, in this case hammer drilling.
• Insert the appropriate SDS-PLUS shank drill bit into the chuck (1).
• For best results, use high-quality drill bits with carbide tips (widia).
• Press the drill bit against the material being worked on.
• Switch on the hammer; the hammer mechanism should operate smoothly
and the working tool should not bounce off the surface of the material
being worked on.
OPERATION AND MAINTENANCE
Before performing any installation, adjustment, repair or maintenance
work, remove the power cord plug from the mains socket.
• Always keep the hammer clean.
• Never use any corrosive agents to clean the plastic parts of the
hammer.
• After finishing work, in order to remove dust deposits, blow the
hammer with a stream of compressed air, , especially to clear the
ventilation slots in the motor housing.
• The condition of the motor carbon brushes must be checked regularly
(dirty or excessively worn brushes can cause excessive sparking and
a drop in the hammer spindle speed).
