IMPACT HAMMER
NOTE: READ THIS MANUAL CAREFULLY BEFORE USING THE
POWER TOOL AND KEEP IT FOR FUTURE REFERENCE.
SPECIFIC SAFETY PROVISIONS
WARNINGS ON WORKING WITH AN ELECTRIC HAMMER
Note: Unplug the power cord from the mains socket before carrying out
any adjustment, operation or repair work.
• Safety glasses or goggles, hearing protection and a safety helmet
should be worn when handling the hammer (if there is a danger that
anything may fall from above). A protective respirator and non-slip
footwear are recommended. Dust extraction systems should be used
if the nature of the work requires it.
• Ensure that the drill chuck of the hammer is properly secured in place
before starting work.
• During operation, the attachment of the tool may loosen as a result of
vibration; therefore, the attachment of the tool must be checked
particularly carefully before starting work. Unwanted loosening of the
tool may cause damage to the tool or an accident at work.
• If the hammer is to be used at low temperatures or after a prolonged
period of storage, the hammer should be allowed to run for a few
minutes without load so that its internal components are properly
lubricated.
• When handling a hammer held aloft, keep your feet firmly apart and
make sure there are no bystanders below.
• Always hold the hammer with both hands, using the auxiliary handle.
• Do not touch the rotating parts of the hammer with your hands. It is
also not permitted to stop the rotating hammer spindle with your
hands. Doing the opposite risks damaging your hand.
• Do not point the working hammer towards other people or yourself.
• When working with the hammer, hold the hammer by the insulated
parts to avoid electrical shock when possibly encountering a live
electrical wire.
• Do not allow any liquid to enter the hammer. Use mineral soap and a
damp cloth to clean the surface of the hammer. Do not use petrol or
other cleaning agents that may be harmful to plastic parts for
cleaning.
• If it is necessary to use an extension cable, always ensure that the
extension cable is selected correctly (up to 15 m, cable cross-section
2
1.5 mm , over 15 m but less than 40 m - cable cross-section 2.5 mm
). The extension cable should always be fully extended.
• The three-jaw drill chuck must not be used when the hammer is set
to work in impact drilling or chiseling mode. This chuck is designed
exclusively for non-impact drilling in wood or steel.
ATTENTION! The device is designed for indoor operation.
Despite the use of an inherently safe design, the use of safety
measures and additional protective measures, there is always a
residual risk of injury during work.
CONSTRUCTION AND APPLICATION
The electric hammer is a hand-held power tool with Class II
insulation. The unit is driven by a single-phase commutator motor.
The hammer can be used for drilling holes in percussion mode,

hollowing channels or surface treatment in materials such as
concrete, stone, brick, etc. Areas of use are the execution of
renovation and construction work, as well as any work in the field
of independent amateur activity (DIY).
Do not misuse the power tool.

PREPARATION FOR WORK
INSTALLATION AND REPLACEMENT OF WORKING TOOLS
The hammer is suitable for use with working tools having SDS-MAX
type shanks. Clean the hammer and working tools before starting.
Using grease, apply a thin layer of grease to the shank of the working
tool. This action will increase the life of the machine.
Disconnect the power tool from the power supply.
• Rest the hammer on the workbench.
• Grasp the retaining sleeve (2) of the SDS holder (1) and pull it back,
overcoming the resistance of the spring.(Fig. A)
• Insert the shank of the work tool into the holder, pushing it in as far
as it will go (the work tool may need to be rotated until it is in the
correct position).
• Release the clamping sleeve (2), which will result in the final fixing of
the tool.
• A work tool is properly seated if it cannot be removed without pulling
back the chuck retaining sleeve.
• If the bushing does not fully return to its original position, remove the
working tool and repeat the entire operation.
High hammer efficiency is only achieved if sharp and undamaged
working tools are used.

DISASSEMBLY OF THE WORK TOOL
Shortly after work, 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 fixing sleeve (2).
• Pull the working tool forward with the other hand.
OVERLOAD CLUTCH
The hammer is equipped with an internally adjusted overload clutch.
The hammer spindle stops as soon as the working tool jams, which
could overload the power tool.
