BASIC TECHNIQUES
Never use the power tool until you have fully read and
understood this User Guide and the equipment has
been properly set up using the information it contains.
The power tool is an electrically-powered breaker with
electropneumatic hammering mechanism designed for
heavy chiseling work. The power tool is designed for
breaking / removing and demolishing concrete, masonry,
stone or asphalt. Working on materials hazardous to the
health (e.g. asbestos) is not permissible.
SETTING SIDE-HANDLE
Set the side-handle to a comfortable working position.
Release the side handle clamping band by turning the
knob. Relax the tension on the side handle clamping ring
and slide it over the chuck and onto the cylindrical section
at the front end of the power tool. Pivot the side handle into
the desired position. Secure the side handle by tightening
the knob.
FITTING STEEL
The chisel can be adjusted to 6 different positions (in 60°
increments). This ensures that flat chisels and shaped
chisels can always be set to the optimum working position.
Before inserting chisel check that the connection end is
clean and lightly greased. Clean it and grease it if necessary.
Push the insert tool into the chuck and rotate it while
applying slight pressure until it engages in the guide grooves.
Push the insert tool further into the chuck until it is heard to
engage.
Check that the insert tool has engaged correctly by pulling it.
SWITCHING ON
To switch on the power tool plug the supply cord into the
power outlet and press the ON / OFF switch.
WORKING AT LOW TEMPERATURES
The unit must reach a minimum operating temperature
before the hammering mechanism begins to operate.
Bring the power tool to the minimum operating
temperature by switching it on and allowing it to run and
warm up. Bring the tip of the chisel into contact with the
work surface at regular intervals (approx. every 30 sec.) to
check whether the hammering mechanism has begun to
operate. Repeat the procedure if the hammering
mechanism does not begin to operate.
NOTE: As starting is electronically controlled, the
power tool’s starting characteristics may be different
in cold conditions.
ELECTRICAL SAFETY
This power tool is designed to plug in to 110V power
socket, so it must be provided with a suitable 110V
generated power supply, or powered from the mains via a
suitable 110V transformer.
When necessary use only extension cords of a type
approved for the application and with conductors of
adequate cross section. The power tool may otherwise
lose performance and the extension cord may overheat.
Check the extension cord at regular intervals. If shows any
signs of damage replace immediately.
When the equipment needs extension cord it is
recommended to use minimum 2,5 mm2cross section cord
with maximum length of 20m.
When working outdoors, use only extension cords that
are approved and correspondingly marked for this
application.
Extension leads should be fully unwound and loosely
coiled, away from the equipment. Never run them
through water, over sharp edges or where they could trip
someone.
If the equipment fails, or if its flex or plug gets
damaged, return it. Never attempt to repair it yourself.
Keep flexes out of harm’s way and clear of moving parts.
To reduce the risk of electric shock, use a suitable
RCD (Residual Current-Operated Device) available
from your local HSS Hire.
Never carry or pull the tool by its flex.
Ensure the equipment is switched OFF before plugging
it into it’s power supply.
