Guaranteed noise level in accordance with Directive
2000/14/EC is indicated by a label under silencer, and a
mark on the silencer marks the group and category the
machinery falls under in accordance with Directive 94/9/EC
–
ATEX.
MAINTENANCE PRINCIPLES
Only personnel properly acquainted with the structure and
function of the hammer can service the tool.
All repairs are to be performed by the manufacturer or
authorized trained personnel.
Dry, clear air of the appropriate overpressure
(see Technical data) must be available in
sufficient volumes.
Supply hose must match the prescribed dimensions.
To avoid excessive frictional pressure loss, do not use
hoses of over 15 meters in length (in case of a Js16
hose). If necessary, hose of a larger diameter can be
used over greater distances.
Protect the hammer from dirt and other harmful
particles getting in. Always keep the input and output
openings clean.
Blow the hose clear to get rid of potentially harmful
particles before attaching it to the hammer.
Properly tighten all joints and re-tighten after 3-5 hours
of first operation.
Check-up on the state of the hammer regularly.
Hexagonal chuck in SKA 12-D and 12-DZ makes use
of chisel type tools possible. The open screw retainer
can be used for wider chisels and facilitates faster tool
replacement. If the hammer operates without sufficient
thrust, the screw retainer can crack under heavy
impacts of the tool!
LUBRICATING
Lubricate the hammer properly to secure maximum service
life of sealing rings of the handle. Damaged rings let air
escape the handle body, limiting vibration dampening or
rendering it virtually ineffective. Sufficient lubrication is
secured with an oiler integrated in the handle. The oiler
needs to be re-filled before every work shift.
Alternatively, pour about 100 cm
3
of oil into the air supply
hose (at the entry point) by the compressor unit and 5 cm
3
into the air inlet at the beginning of each work shift and
repeat every 2-3 hours of operating.
Thrust
With regards to vibrations
and manipulation of the
hammer, the optimal thrust is
between 150
–
200 N.
The thrust must prevent the
hammer from working idly,
which increases wear and
chance of breakdown.
Tool insertion
Unscrew retainer with ring.
Always check the state of
rubber ring. Insert tool into
cylinder and screw retainer
back on.
The SKA 12-DZ version with
latch retainer comes without
a ring. Insert tool by tilting
the latch and then close the
retainer.
Never
start
a
hammer
without a tool inserted!
