Risk of Hand Arm
Injury
Because of various factors, the range of
vibration emission during intended use of
these tools are expected to be between
8.5m/s
2
and 84m/s
2
dependent on the tool
purchased. The vibration is dependent on the
task, the operators grip, and feed force
employed etc.
Vibration measured in accordance with:-
EN ISO 28927 and EN ISO 20643
Declared vibration emission values were
obtained under laboratory conditions in
compliance with the above stated standards
and do not necessarily represent values
obtained in service.
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 specified by local
regulations.
Note:
Flammable material such as plastic, rubber or
composite materials must NOT be incinerated
but should be subject to normal industrial
waste disposal processes.

STYLE A
Hold the Body (13) vertically in a vice. Insert
the Piston (9), small diameter first into the
bore.
Fit a new O’Ring (17) onto the shoulder near
the top of the body.
Screw the Valve body by hand into the Body,
and then tighten using a suitable spanner
using the flats provided.
STYLE B
Fit two new O’Rings (11) and (12) onto the
Cylinder (10).
Insert the Piston (9), small diameter first into
the bore.
With clean, dry and oil free threads apply a
bead of Loctite 243 or similar adhesive to the
central portion of the Cylinder (10) threads.
Screw the Cylinder (10) fully into the Cover
Assembly (14) by hand.
Then holding the Cylinder in a vice using the
flats provided, tighten fully by hand, then,
using a rubber mallet, tap lightly on the handle
until tightened fully.
STYLE C
Hold the body (13) vertically in a vice, with the
handle uppermost, insert the Cylinder (10),
small bore first into the Body (13), then the
Piston (9), small diameter first, into the
Cylinder (10).
Fit a new O’Ring (17) into the Body (13) to sit
on top of the Cylinder (10).
Screw the End Cap (15) down by hand, then
using a suitable wrench tighten fully.
Noise and Vibration
UK employers should be aware of their duties
under the Health & Safety at Work Act 1974
and the guidance given regarding hand arm
vibration in the H.S.E. publication “Control the
risks from hand-arm vibration” INDG175
(rev2).
(Single copies are available F.O.C. See
H.S.E. web site www.hse.gov.uk)
Employers in the rest of the world should be
aware of their duties and responsibilities as
specified in local regulations.
The employer is responsible for assessing the
risk to the employee under actual working
conditions.
Noise level measured in accordance with
EN ISO 15744: 1999
STYLE A
Hold the Body (13) firmly in a vice, with the
Valve Body (6) uppermost and using a
suitable wrench and using the flats provided,
unscrew the Valve Body (6).
Remove the O’Ring from the Body (13) then
remove the Piston (9).
Inspect all components for signs of wear,
particularly the small bore of the Body,
replace components as necessary.
STYLE B
Hold the Cylinder (10) firmly in a vice, using
the flats provided and with the Valve
Assembly uppermost, unscrew the cover (14)
from the cylinder (10).
The Cylinder (10) has been secured with a
retaining compound and may require a sharp
blow on the handle using a rubber mallet to
break this bond.
Remove the two O’Ring seals (11) and (12)
and the Piston (9).
Inspect all components for signs of wear,
particularly the small bore of the Cylinder,
replace components as necessary.
STYLE C
Hold the Body (13) vertically in a vice, with the
handle uppermost and unscrew the End Cap
using a suitable wrench.
Remove the O’Ring (17), Piston (9) and
Cylinder (10).
Inspect all components for signs of wear,
particularly the small bore of the cylinder,
replace components as necessary.
Assembly
Before any assembly takes place, ensure all
parts are clean and are coated in a thin film of
recommended air tool lubricant.
It is strongly recommended that all the
O’ Rings and any other worn parts that show
signs of wear be replaced using only genuine
Trelawny spares.
All Valve Body Assemblies
Clamp the Valve Body firmly in a vice, using
the flats provided, and with the threaded hole
uppermost.
Insert the valve seat 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 (1)
with a screwdriver.
Rotate assembly 180 degrees in the 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.
Piston and Cylinder Assembly
To assemble the Scaler with a new Piston (9)
or Cylinder (10), refer to the specific
instruction for each style.
