Machine type and serial
number are embossed on
the handle.
TECHNICAL DESCRIPTION
The hammering section (cylinder, distribution and piston) is
slidably mounted to a controlling section (handle, nut, pipe)
and does not come into contact with hands of the operator.
A pneumatic and a mechanical springs are positioned
axially inbetween the controlling and hammering sections.
The two sections are prevented from relative rotation by a
pen and held together by a nut. Compressed air is in turns
filling spaces below and above a floating piston head in the
hammer cylinder, setting piston into linear reciprocating
motion. In power stroke, piston transfers its kinetic energy
to a tool that disrupts the material. Exhaust air leaves the
hammer through a series of holes in silencer. The silencer
can be rotated into arrested positions, directing the exhaust
air to ensure safety and comfort. The sliding mounting of
the cylinder to the handle and the two springs inbetween
prevent vibrations from transferring onto the handle in full
force. An integrated oiler ensures proper lubrication.
MODEL LABELLING
Machines are fitted with labels containing important
information. Keep these labels clean and readable at all
times and order new ones as necessary.
The main label should be found on the handle.
The 'CE' symbol states that the product is EC-approved
(see EC-Declaration of conformity).
Maximum permitted compressed air pressure is stated in
the top right corner.
The opened book symbol states that user has to read and
understand the manual before using the machine for the
first time.
The headset symbol reminds user to wear effective ear
defenders.
The last symbol reminds user to wear safety goggles.
