Foreseen Use of the Tool

This tool is designed for the purpose of the removal of gaskets,
gasket residue, trim that has been bonded to vehicles etc.,
adhesive residue, decals, paint and rust etc. Do not use the tool
for any other purpose than that for which it is designed. Do not
modify the tool for any other use or for its use as a scraper
without first consulting the manufacturer or an authorised
distributor

Work Stations

The tool should only be used as a handheld, hand operated tool.
It is always recommended that the tool is used when standing
on a solid floor. It can be used in other positions but before any
such use, the operator must be in a secure position having a
firm grip and footing and be aware of a reaction force on the
hand as result of the tool doing work.

not connect the tool to the air line system without incorporating
an easy to reach and operate air shut off valve. The air supply
should be lubricated. It is strongly recommended that an air
filter, regulator, lubricator (FRL) is used as shown in Figure 1 as
this will supply clean, lubricated air at the correct pressure to the
tool. Details of such equ ipment can be obtaine d from your
supplier. If such equipment is not used then the tool should be
lubricated by shutting off the air supply to the tool,
depressu rising the line by pressing th e trigger on the tool.
Disconne c t th e a ir line an d pour into the in ta ke bu sh ing a
teaspoonful (5ml) of a suitable pneumatic motor lubricating oil
preferably incorporating a rust inhibitor. Reconnect tool to air
supply an d run tool slowly for a fe w seconds to allow a ir to
circulate the oil. If tool is used frequently lubricate on daily basis
and if tool starts to slow or lose power.
It is recommended that the air pressure at the tool whilst the
tool is running is 90 p.s.i./6.3 bar. The tool can run at lower and
higher pressures with the maximum permitted working air
pressure of 100 p.s.i./7.0 bar.

Air Supply

Use a clean lubricated air supply
that wi ll g ive a meas ured ai r
pressure at the tool of 90 p.s.i./

6.3 bar when the tool is running
with the trigger fully depre ssed.
Use recommended hose size and
length. It is re commen ded that

Operating

Fit scraping blade (17), (18), (19) or (20) as required and
connect tool to a suitable air supply. The knob on the side of the
air regulator (8) controls the air flow to the tool and allows
variation in the power and number of blows made by the piston
to the scraping blade. The trigger (6) is the on/off valve for the
tool. To prolong tool life always try to ensure that the scraping
blade as fitted is in contact with the workpiece before starting
the tool. This tool has a high vibration level and its use should
be limited to periods of just a few minutes at a time rather than
continual unbroken usage.

Dismantling & Assembly Instructions

Disconnect tool from the air supply.
Remove 2 off lock scr ews (16) with he x wren ch (22) and
remove scraping blade (17), (18), (19) or (20) as fitted. Drive out
roll pin (7) and take off trigger (6). Unscrew air regulator (8) from
handle (1). Remove screw plug (2) and take out spring (3) and
valve stem (4) with O-ring (5). Grip cylinder assembly (13) and
loosen locknut (21) on blade holder (15) to allow the blade
holder to be unscrewed from the cylinder assembly (13). Still
gripping cylinder assembly (13) unscrew handle (1) from it.
Remove upper valve (9), middle valve (10), lower valve (11) and
valve disc (12) from the end of, and the piston (14) from the
bore of cylinder assembly (13). Note for reassembly how the
two pins and the hole in lower valve (12) align with the three
holes in the end of cylinder assembly (13).

Reassembly

Clean all parts and examine for wear. Replace any worn or
damaged parts with parts obtained from the manufacturer or an
authorised distributor. Coat all parts in a pneumatic tool
lubricating oil and reassemble in the reverse order.

and observ e all r ele va nt lega l requ irem ents wh e n in st alling,
using or maintaining the tool.

16) Do not install the tool unless an easily accessible a nd easily
operable on/off valve is incorporated in the air supply.

17) Take care that the tool exhaust air does not cause a problem
or blows on another person.

18) Never lay a tool down unless the working attachment has
stopped moving.

19) Never point a tool at any person.

20) Use only suitable pneumatic tool lubricants. This is important
as a safeguard against the “diesel effect” i.e. explosive mixtures
firing.

21) Prolonged exposure to vibration can cause injury.

Safety Rules For A Gasket Scraper

1) Read all the instructions before using this tool. All operators
must be fully trained in its use and aware of these safety rules.

2) Do not exceed the maximu m working air pressure.

3) Use personal safety equipment.

4) Use only compressed air at the recommended conditions.

5) I f the too l appea rs to mal functio n remove f rom use
immediately and arrange for service and repair.

6) If the tool is used with a balancer or other support device
ensure that it is fixed securely.

7) Always keep hands away from the working attachment fitted
to the tool.

8) The tool is not electrically insulated. Never use the tool if there
is any chance of it coming into contact with live electricity.

9) Always when u sing the tool a dopt a firm footing and/or
position and grip the tool firmly to be able to counteract any
forces or reaction forces that may be generated whilst using the
tool.

10) Use only correct spare parts . Do not improvise or make
temporary repairs.

11) Do not lock, tape, w ire, etc. the on/off va lve in the run
position. The trigger/lever etc. must always be free to return to
the 'off' position when it is released.

12) Always shut off the air supply to the tool, and depress the
trigger/lever etc. to exhaust air from the feed hose before fitting,
adjusting or removing the working attachment.

13) Check hose and fittings regularly for wear. Replace if
necessary. Do not carry the tool by its hose and ensure the hand
is remote from the on/off control when carrying the tool with
the air supply connected.

14) Take care against entanglement of moving parts of the tool
with clothing, ties, hair, cleaning rags, etc. This will cause the
body to be drawn towards the tool and can be very dangerous.

15) It is expected that users will adopt safe working practices
