BRIEF DESCRIPTION
A percussion unit generates the power necessary for
hammer drilling or chiselling in masonry.
Just like when we hit a conventional chisel with
hammer, a free piston strikes the bit or chisel, which can
move lengthways, through an intermediate part. This free
TECHNICAL DATA
piston is driven by a second piston activated by an electric
motor through an air cushion. This electro-pneumatic
principle offers great percussion elasticity and work free
from recoil.
Unlike a normal hammer drill, the drilling capacity
does not depend on the pressure exerted on the machine.
Use of the tool: The rotary hammer can be used
for hammer drilling and drilling in wood, metal as well as
plastic, and also for driving screws with driving bits installed
in a key chuck with the SDS-plus adapter. Any other use
not mentioned is not allowed.
Additional features of the rotary hammer:
- The machine is equipped with a safety clutch or
mechanism which operates when a bit seizes up, pro-
tecting the user and the machine’s electro-mechanical
parts. The clutch is released automatically.
WARNING!
This machine must not be used with hole
saws, core bits, diamond bits, etc, as they tend to jam in
the hole easily. This would cause the safety clutch to trip
out too often.
- Percussion drill chuck

BEFORE USING THIS TOOL
WARNING!
Before carrying out any work, check, for
instance, using a metal detector, that there are no electric
wires or gas or water pipes under the surfaces you wish to
work on.
Make sure the mains voltage is correct: it must be
the same as that on the specification label. Machines with
230V can also be connected to a 220V mains supply.
To turn the machine on, press the ON/OFF switch
H
and keep it pressed down.
When the ON/OFF switch is released, the machine
