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 screws (16) with hex wrench (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.
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 maximum working air pressure.
3) Use personal safety equipment.
4) Use only compressed air at the recommended conditions.
5) If the tool appears to malfunction remove from 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 using the tool adopt 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, wire, etc. the on/off valve 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
and observe all relevant legal requirements when installing, using
or maintaining the tool.
16) Do not install the tool unless an easily accessible and 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.
