SAFETY INSTRUCTIONS
See “
Safety instructions
” enclosed manual, supplied
together with this instruction manual.
Warning!
When drilling in amianthus/asbestos and/or
silica stone, the dust produced is extremely harmful to
your health. Wear protection against inhalation of this
dust, in compliance with current regulations on accident
prevention. Follow the insurance company’s safety in-
structions regarding the responsibility of employees.
For your personal safety, always connect the machine
to a mains supply by a differential and thermal cut-out
switch, in accordance with regulations on low-voltage
wiring sitemaps.
Do not perforate the machine casing, as this would
destroy the protective insulation (use adhesive labels).
Always unplug the machine before doing any work on it.
Warning!
Before each use, inspect the plug and lead.
Should they need replacing, have this done by an offi-
cial service centre. Only plug the machine in when it is
switched off.
Always keep the lead out of the machine’s working area.
Only plug the machine in when it is switched off.
Do not allow the machine to get wet, nor should it be
used in wet environments.
When using the machine, always wear safety goggles,
gloves and non-slip footwear, and it is advisable to
wear ear protection.
Do not touch the bit when during or immediately
after working, as it becomes very hot and can
cause serious burns.
Hold the machine firmly by the handle and the auxiliary
handle, otherwise the recoil produced could cause the
machine to work imprecisely or even dangerously.
Always use the auxiliary handle.
Never attempt to clean off dust or shavings resulting
from drilling when the machine is operating.
Do not use diamond core bits.
When drilling walls, ceilings or floors, take care to
avoid electric wires and gas or water pipes.
BRIEF DESCRIPTION
A pneumatic percussion unit generates the power nec-
essary for hammer drilling or chiselling on masonry.
Just when we hit a conventional chisel with a hammer, a
free piston strikes the bit or chisel, which can move
lengthways, through an intermediate part. This free
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 machine:
RHF models can be used for percussion drilling and
chiselling in stone.
Any use differing from the above mentioned is strictly
forbidden.
Additional features of the electro-pneumatic hammer:
-
The machine is equipped with a safety clutch or mecha-
nism, which operates when a bit seizes up, protecting
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.
