OPERATION
General Information
Before operating Trelawny Scaling
Hammers, this manual must be read and
understood by the operator, if in any
doubt, ask your supervisor before using
this equipment. Local safety regulations
must be followed at all times. Failure to
follow these instructions could result in
damage to the Scaler and/or personal
injury.
Trelawny SPT Ltd disclaims all
responsibility for damage to persons or
objects arising as a consequence of
incorrect handling of the tool, failure to
inspect the tool for damage or other
faults that may influence it’s operation
prior to starting work, or failure to follow
the safety regulations listed or applicable
to the job site.
The standard scaling tools are primarily
designed for removal of heavy rust and
scale.
The heavy-duty versions is suitable for
concrete reduction and the removal of
laitance from concrete.
These tools must not be used in a
fixture.
Note: Cruciform headed pistons are
suited to the removal of heavy rust and
scale and for the reduction of concrete
where a smoother finish is required;
these will reduce the aggregate as well
as the concrete surface.
Bush Hammer style headed pistons are
best suited to concrete reduction and for
laitance removal; these also reduce the
damage caused to the aggregate,
ensuring that a stronger bond is created
with the next layer.
Air Supply
The compressed air must be free from
water and dirt. The installation of a filter/
regulator/lubricator air preparation set
(with moisture trap) adjacent to the tool
is strongly recommended.
Always clear the air hose before
connection to the tool. Ensure that no
moisture (condensation) is present in the
air hose.
Ensure that a minimum 10mm (3/8”)
bore air hose is used and that all
couplings are secure, leak free and in
good condition.
Limit the length of air hose to 10M (33ft).
Where extra length is necessary, for
each additional 15M (50ft) of air hose
used, the pressure drop is approximately
0.16bar (3psi).
Correct operating pressure is 6.2bar
(90 psi).
Do not let the operating pressure fall
below 5.5bar (80p.s.i.) or rise above
6.9bar (100 psi) absolute maximum.
The compressor must be able to supply
a minimum of 7.0 lps (15cfm) for Single
Scalers and 12 lps (25cfm) for Triple
Scalers, (Free air, not displaced as
quoted by some compressor
manufactures).
In particularly cold weather it is
recommended that a proprietary anti-
freeze lubricating oil is used.
Safety
Always, read instructions first before use.
Do wear Personal Protective Equipment
including safety goggles, footwear, ear
defenders and gloves. In some
environments it will be necessary to wear
facemasks or breathing apparatus.
Do be aware that this tool is not
electrically insulated.
Do keep hands and clothing away from
moving parts.
Do ensure that this tool is lubricated
daily.
Do be aware that the tool can create
dust and
flying debris.
Do be aware of others working around
you.
Do store this tool in a secure and dry
environment.
Always observe safe-working
practices at all times.
Do not allow the tool to run unattended.
Do not use this tool in potentially
explosive environments.
Do not drag this tool by the air hose.
Do not use the Scaler as a lever.
Do not use petrol (gasoline), thinners or
any other high flash point solvent to
clean the tool.
Do not modify this tool in any way, as
this will invalidate the warranty and could
lead to serious injury.
Risk of Hand-arm
Vibration injury
These tools may cause Hand-arm
Vibration Syndrome injury if their use is
not adequately managed.
We advise you to carry out a risk
assessment and to implement measures
such as; limiting exposure time [i.e.
actual trigger time, not total time at
work], job rotation, ensuring the tools are
used correctly, ensuring the tools are
maintained according to our
recommendations, and ensuring that the
operators wear personal protective
equipment [PPE] particularly gloves
and clothing to keep them warm and
dry.
Employers should consider setting up a
programme of health surveillance to
establish a benchmark for each operator
and to detect any early symptoms of
vibration injury.
We are not aware of any PPE that
provides protection against vibration
injury by attenuating vibration emissions.
See ‘Specifications’ section for
vibration emission data.
Further advice is available from our
Technical Department.
Recommended
lubricants
Oil the tool daily before use. Put a few
drops of one of the following zinc free air
tool lubricants through the air inlet.
SHELL S22 or R10
CASTROL Hyspin ZZ32
Cleaning
At intervals of no more than 40 hours or
if operation becomes unproductive and
the piston shows signs of sticking,
dismantle and clean with a highly refined
paraffin.
Immediately after cleaning, thoroughly oil
the tool with one of the recommended
lubricants.
Starting work
Prior to operating the tool check: -
That all fittings are secure, free from
leaks and air hoses are in good
condition.
That the air pressure is correct for this
tool 6.2 bar (90 p.s.i.). Put a few drops of
recommended lubricant into the air inlet
of the tool.
To operate the tool, which is dependant
on the type of lever fitted, for those fitted
with a safety lever, first push thumb
button forwards and then for both styles
of lever, pull the lever towards the
handle grip to start the tool, then apply
the cutter heads to the surface being
prepared.
To switch off, simply release the
throttle lever.
Care must be taken to avoid damaging
or tripping over the air hose. Maintain
contact with the work surface with
sufficient pressure only to keep the tool
from bouncing off. Excessive pressure
can prevent the tool from working to its
full capacity. Handled correctly the
Scaler will work quickly and efficiently.
