RISK OF HAND-ARM VIBRATION INJURY
air supply
STARTING WORK
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 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 ‘Specications’ section for vibration emission data.
Further advice is available from our Technical Department.
The compressed air must be free from water and dirt.
The installation of a lter/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 antistatic 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 (90psi).
Do not let the operating pressure fall below 5.5bar (80psi.)
or rise above 6.9bar (100psi) absolute maximum.
The compressor must be able to supply a minimum of
7.0 lps (15cfm) for Single 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.
Always use Trelawny Beryllium Copper heads.
Prior to operating the tool check that all ttings are secure,
free from leaks and air hoses are in good condition.
That the air pressure is correct for this tool 6.2 bar (90psi.). 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 tted, for those tted with a safety lever, rst 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 o, 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 sucient
pressure only to keep the tool from bouncing o. Excessive
pressure can prevent the tool from working to its full capacity.
Handled correctly the Scaler will work quickly and eciently.

Valve Body assembly (Workshop)
Clamp the handle (10) assembly rmly in a soft faced vice
(valve body end), insert new valve stem ‘O’Ring (5) into valve
body (6), followed by the valve stem (4), spring (3), then the
valve cap (1) complete with its ‘O’Ring (2), tighten the valve cap
with a screwdriver. Rotate assembly 180 degrees in vice. Using
a 3mm diameter pin punch locate and align the throttle lever
(7) in position, then drive in the throttle lever roll pin (8) into the
pin location.
FINAL ASSEMBLY (Workshop)
Assemble the end cap (17), t spring (18) into the end cap and
t spring cap (19) into the end cap as shown in the service
layout. Select as required, a piston/cutterhead, insert into the
body (24) and apply a few drops of air tool lubricant to the
top of the piston(s). Hold the handle (10) in a soft faced vice
ensuring the screw cap threads are uppermost. Remove all
traces of oil from the screwed cap threads and threads of the
body by cleaning with suitable oil free solvent. Apply a bead
of Loctite 243 sealant to the rst 3 threads of the end cap.
Screw end cap assembly into the body until nger tight and
using a suitable spanner torque down to 55N.m. (40 lbs.ft).
DISPOSAL
When the tool and its accessories are taken out of service
for disposal, it is recommended that: - They are rendered
unusable to prevent improper re-use.
They are dismantled into component form, segregated
according to material composition and disposed of using
waste recycling processes specied by local regulations.
VERY IMPORTANT
Only Trelawny Beryllium Copper Heads must be used in
this tool. DO NOT substitute with any other head.
MAINTENANCE
Excessive operator pressure will not improve the tool
eciency but will cause premature tool failure and operator
fatigue. Never allow the tool to run continuously whilst not in
contact with the surface being prepared.
Please be aware: that this tool will reduce in power or stop
working if the end cap (17) has become unscrewed.
Maintenance must only be carried out by a competent person.
Disconnect the tool from the air supply before carrying out any
of the following operations. Clean all debris from the exterior
of the tool.
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
Always use clean oil from a sealed container and ensure
ignition temperature is above 185degC°.
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 rened paran.
Immediately after cleaning, thoroughly oil the tool with one of
the recommended lubricants.
Head removal - Taper Fit (On site)
Lay the scaling hammer on a solid surface with the cutter
head (25) facing uppermost. Place the head removal washer
(32) between the cutter head and the body; insert the removal
pin (31), into cutter head hole (refer to diagram for pictorial
illustration). Wearing safety glasses and using a medium size
hammer give a sharp blow to the head of the pin, which will
release the cutter head from the piston.
Piston/Cylinder Assembly removal (Workshop)
Hold the scaler body (24) in a vice, using the ats provided and
with the end cap uppermost. On triple scalers, secure the tool
in a vice, clamping on all three cutter heads. Unscrew the end
cap (17). Remove spring cap (19) and spring (18) from the end
cap. From the bottom of the body, push up the cutter head to
remove the piston assembly.
Head Removal - Taper Fit (Workshop)
Lay the piston and cylinder assembly on a solid surface with
the cutter head facing uppermost. Place the head removal
washer (32) between the cutter head and the cylinder; insert
the removal pin (31), into cutter head hole (refer to diagram
for pictorial illustration). Wearing safety glasses and using a
medium size hammer, give a sharp blow to the head of the
pin, which will release the cutter head from the piston. Inspect
all components for wear, replace as necessary.
Valve body servicing (Workshop)
Clamp the handle (10) assembly rmly in a soft face jawed
vice (valve body end) throttle lever upper most. Using a 3mm
diameter pin punch, remove the throttle lever roll pin (8), and
then remove the throttle lever (7). Rotate the tool 180 degrees
in the vice to access the valve. Unscrew the valve cap (1) using
a screwdriver, check the valve cap ‘O’Ring (2), remove the
spring (3), push out the valve stem (4) and remove the ‘O’Ring
(5). Check the valve and ‘O’Ring for wear.
Assembly (Workshop)
Before any assembly takes place, ensure all parts are clean
and have a lm of air tool oil lubrication unless otherwise
stated. Avoid lubricating oil or grease contaminating the
threads of the end cap (17), the threads within the bore of the
bodies (24) and the tapers on piston and cutter heads. The
end caps will require securing with a thread-locking adhesive.
It is good practice to renew all ‘O’ Rings (2/5) and the brush
seals (22). Replace any parts showing signs of wear; paying
particular attention to the small bore of the cylinder.
Head Assembly - Taper Fit (On-Site)
Thoroughly clean around area of cutter head and piston.
Remove all traces of debris/oil from the taper on the piston
(20) and internal taper of the cutter head (25) by cleaning with
suitable oil free solvent. Place the tool in a position where the
end cap is on a solid surface; Select one of the cleaned new
cutter heads and place onto the taper of the piston. Using a
soft-faced hammer deliver a sharp blow to the cutter head.
Head Assembly - taper t (Workshop)
Remove all traces of oil and dirt etc, from the taper diameter
on the piston (20) and cutter head (25) by cleaning with
suitable oil free solvent. Fit the piston into the cylinder (21) as
shown in the service layout. Place the assembly onto a solid
surface; t a new brush-seal (22) over the piston and into the
recess of the cylinder. Select one of the cleaned new cutter
heads and place onto the taper of the piston. Using a
soft-faced hammer deliver a sharp blow to the cutter head.
Note: If you are re-tting a used cutter head to the piston it
is essential that the internal diameter of the cutter head is
re-surfaced using a medium grade of emery cloth - this will
ensure a good t between cutter head and piston, do not
use adhesive of any description on the taper. If the taper has
expanded too much on the old cutter heads, they may not
stay on the piston, replacements will be required.
Piston/Cylinder assembly (Workshop)
Lubricate the piston (20) and cylinder bore (21) and push the
piston into the cylinder bore. Lay the tool on a bench with the
body (24) on its side and insert the cylinder assembly into the
body.

Trouble Shooting Cause Action
Poor performance or lack of power.
Low air pressure. Ensure that the air pressure is correct at 90psi, max 100psi.
If tool has been left for some time without use, the oil may dry out
slightly, causing a sticky residue. Strip tool down, clean and re-oil.
Tool worn out, can you feel side ways movement between the piston
and cylinder bore. Replace the piston and cylinder, along with a new bush seal.
Tool continues to run with trigger released. Valve seal may have become dislodged through the tool being
disconnected with the trigger in the open position.
Ensure that the trigger has not been taped or wired in the
open position.
Tapered cutterhead will not stay on piston.
Air pressure too high, piston hits bottom of cylinder
causing head to be jettisoned. Ensure that the air pressure is correct at 90psi, max 100psi.
Traces of oil remained on the tapered surfaces when replacing
cutter head.

Noise Levels: Noise level measured in accordance with: EN ISO 15744: 2008
Vibration Levels: Vibration measured in accordance with: EN ISO 28927-9:2012 and EN ISO 20643:2005. (k) Equals the factor of uncertainty, which allows for variations in
measurement and production. Vibration Data gures 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% (9.9 m/s2 -13.86 m/s2). 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 28927-9:2012 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)).
