Before starting work drain any water from the
air tank and blow condensation from the air
line. Drain compressor more frequently in hot
humid weather.
Kit Contents
1. The Main Body inc Hammer assy.
2. The Needle Holder, complete.
3. Three Chisels with Spring Retainer.
Depending on the work to be carried out,
choose either Needles or Chisel.
WARNING
Always ensure air is turned off before
installing or removing tools etc.
To install the Needle Tube, complete with
Needles. P ush the assy on to the nose of the
tool, and screw in fully, (HAND TIGHT ONLY).
To install a Chisel, unscrew the Needle Tube
assy, if fitted, and insert Chisel into the hole in

OPERATING INSTRUCTIONS
MAINTENANCE
Daily before use.
1.
Drain water from air tank, air line and
compressor.
2.
Check and clean, if necessary, the air
inlet gauze filter .
3.
Pour a few drops of CLARKE Air Line Oil
(approx 3cc), into the air inlet. This should
be carried out regardless of whether or
not an air line lubricator is used.
If an Air line lubricator is NOT used, this
procedure should be repeated after
every two to three hours of use.
If the Descaler is to be stored, or is idle for
longer than 24 hours, run a few drops of
Clarke Air Line Oil into the air inlet, and run
the tool for 5 seconds in order to lubricate
the internal parts.
For lubricating the air motor when in
operation, an air line lubricator should be
used, with Clarke Air Line Oil, adjusted to 2
drops per minute.
Clarke Air Line Oil is available from your
CLARKE dealer, part no. 3050825.
Be aware that factors other than the tool may
effect its operation and efficiency, such as
reduced compressor output, excessive drain
on the airline, moisture or restrictions in the
line, or the use of connectors of improper size
or poor condition which will reduce air supply.
Grit or gum deposits in the tool may also
reduce efficiency. This condition can be
corrected by cleaning the air strainer and
flushing out the tool with gum solvent oil,or
failing this, the tool should be dis-assembled,
thoroughly cleaned, dried and re-assembled.
If the tool runs erratically or becomes
inefficient, and the air supply is sound,
dismantle the air motor and replace worn or
damaged parts, or take the tool to your
CLARKE dealer.
Once the appropriate tool is fitted, you are
ready to start.
Turn ON the air supply, and check for air leaks,
if any are apparent, rectify before
proceeding. Ensure the air pressure is set to
90 PSI (6.2bar).
Hold the tool with one hand around the
handle and the other around the barrel, bring
the tool towards the work at an angle of
approx, 60 - 70º. Depress the trigger and allow
the Needles/Chisel to come into contact with
the work.
Needle/Chisel force can be adjusted by
turning the regulator knob, located at the
base of the handle grip.
To increase force, turn reg clockwise and
anticlockwise to reduce.
Place the Spring
retainer over the
Chisel and screw on
to the nose fully,
using the
appropriate lug,
(See Fig. 1).
Fig. 1
moving slowly across work surface, proceed
to remove scale, rust or other contaminants.
Release the trigger to stop operation, noting
that the tool may impact briefly after the
trigger is released.
