OPERATION
General Information
Before operating, performing maintenance or
repairing the TVS Needle Scaler 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 Limited 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
the operation prior to starting work, or failure
to follow the safety regulations listed or
applicable to the job site.
The tool is primarily designed for the removal
& containment at source, paint, heavy rust,
and scale; it can also be used for the removal
of laitance from concrete. It can be used both
indoors and out.
This tool must not be used in a fixture.
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 connecting 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 0.21bar
(3psi).
For safe and efficient operation the 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.
Preferably, the compressor should be able to
supply a minimum of 4.7 L/s (10 cfm) free air
delivery.
In particularly cold weather it is recommended
that a proprietary anti-freeze lubricating oil is
used.
Lubrication
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
See also the section on AIR SUPPLY for
further information and recommendations.
Safety
Always, read through these instructions first
before use.
Do-
Be aware that this tool is not electrically
insulated.
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.
Be aware that this tool can create dust and
flying debris.
Keep hands and clothing away from moving
parts.
Store this tool in a secure and dry
environment.
Be aware of others working around you.
Ensure that this tool is lubricated daily.
Always observe safe-working practices at
all times.
Do not-
Allow the tool to run unattended.
Modify this tool in any way, as this will
invalidate the warranty and could lead to
serious injury.
Allow the tool to run continuously whilst not in
contact with the surface being prepared.
Use the tool if you become tired, this can lead
to physical strain or injuries; where practical;
use a spring balance to take the weight of the
tool.
Hold the exposed needles, whilst the tool is in
use, this could cause vibration damage to the
hands.
Use this tool in potentially explosive
environments.
Drag this tool by the air hose.
Use petrol (gasoline), thinners or any other
high flash point solvent to clean the tool.
Please note: Unrestrained hoses can whip
dangerously if they become detached.
Care must be taken to avoid damaging or
tripping over the trailing air hose.
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
m a i n t a i n e d a c c o r d i n g t o o u r
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
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.
We strongly advise you to visit the Health &
S afet y E xe c utive we bsit e http: / /
www.hse.gov.uk/vibration This site provides
excellent advice and information on HAV and
it includes a Hand-arm Vibration Exposure
Calculator that is easy to use to work out the
daily vibration exposure for each of your
operators.
Starting work
Please note:
The carbon steel needles provided with these
tools are not intended for use in a potentially
explosive atmosphere.
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 a 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 hand grip to start the tool, then
apply the Chisel or Needles to the surface
being prepared.
Note: Several types of Chisel are available for
the Chisel Scaler to suit the job in hand.
To switch off, simply release the throttle
lever.
It is advisable that gloves and personal
protective equipment be worn when using this
tool.
(See previous section on Risk of Vibration
Injury).
Take care to avoid tripping over or damaging
the air hose.
Safe use of this tool requires a solid stance
and secure foothold, the tool may be used in
other postures but care must be taken to
ensure the operator adopts a firm and stable
position.
Maintain contact with the work surface with
sufficient pressure to keep the tool from
bouncing off the surface.
Handled correctly Trelawny Needle/Chisel
Scalers will work quickly and efficiently.
Excessive operator pressure will not improve
the tools efficiency but could cause premature
tool failure and increase operator fatigue.
It could also increase the vibration emission
level.

MAINTENANCE
Pointed tip needles
Sharpened to a nail point, these are most
effective in breaking through very hard scale
on surfaces where some surface indentation
is permissible - or where keying (i.e. profile) of
the surface is desirable.
Pointed tip needles are available in 3mm and
4mm only.
Chisel tip needles
These are general purpose needles, flattened
to a chisel like blade and are most effective in
the removal of thicker material, while leaving a
less pitted surface than the Pointed tip
needles but still giving some surface
indentation (i.e. profile).
Chisel tip needles are available in 3mm only.
Flat tip needles
Machined to a flat tip, these needles will leave
slight marking (i.e. profile) on the surface; the
2mm needles can have a burnishing effect.
2mm Needles are recommended for use on
thin gauge metals and any surface where light
treatment is desired.
Flat tip needles are available in three sizes -
2mm, 3mm and 4mm.
SEE SPECIFICATION SECTION FOR
QUANTITIES.

SPECIFICATION
H1* Indicates that the test was taken at the primary handgrip location, next to the throttle lever.
H2* Indicates that the test was taken at the secondary handgrip position.
(k) ** Equals the factor of uncertainty, which allows for variations in measurement and production. Vibration Data figures are tri-axial, which gives the total vibration
emission. Because of various factors, the range of vibration from these tools may vary between -0% +40%. The vibration is dependent on the task, the operators grip and
feed force employed etc.
NOTE: The above vibration levels were obtained from tri-axial measurements to comply with the requirements of “The Control of Vibration at Work Regulations 2005*” and
the revisions to the (8662) now EN ISO 28927-9:2005 and EN ISO 20643:2005 series of standards. These values are at least 1.4 times larger than the values obtained from
single axis measurements.
*Based on European Union Council Directive 2002/44/EC (Physical Agents (Vibration) Directive)
and applicable harmonised standard: EN ISO 1 1148-4:2012
