incorporating a rust inhibitor. Reconnect tool to air supply and run tool
slowly for a few seconds to allow air 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 bar.
Operating
Select a suitable abrasive disc (see Section "Foreseen use of the tool")
and make sure that it is fixed securely to the tool. Connect to suitable air
supply as recommended. Make sure that the side handle is tightened
securely.
Apply the sander lightly to the work and allow the abrasive disc to cut.
Take great care when sanding around sharp edges and surfaces to
avoid the disc snagging i.e. the disc may be brought to an abrupt stop or
considerably slowed that will cause the tool to kick in the hands.
It is always recommended to use safety glasses and a breathing mask.
The sanding of certain materials may create a hazardous dust which
may require special breathing equipment. Check before using the tool.
Even if the machine has a low noise level the actual sanding process
may cause a noise level such that ear protectors will be required. If there
are sharp areas on the material being sanded safety gloves are
recommended.
Do not continue to use abrasive discs that are worn or clogged. This will
make the sanding process inefficient and the need to apply
unnecessarily high forces to the tool.
Do not use undersized or oversized sanding discs. The disc should be
no more than 1/4" larger in diameter that the pad, and not smaller than
the pad.
Dismantling & Assembly Instructions
Disconnect the tool from air supply
Remove abrasive paper. Push service wrench (41) between housing
cover (37) and pad (40-1) and remove pad (40-1). Unscrew the 4
screws (38) and remove the housing cover (37). Pull out the motor
assembly parts (18 to 36) from housing (17). Disassemble the motor
assembly step by step. To remove the bearing (20) from the rear plate
(21) first take off the snap ring (19)
Reassembly
Clean all parts and examine for wear. Coat all metal parts in a pneumatic
tool lubricating oil, one preferably incorporating a rust inhibitor, and
grease all bearings with a molybdenum or lithium based general
purpose grease. Reassemble in the reverse order.
Safety Rules For A Sander
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) Always check the speed of the attachment is higher than the speed
of the tool.
20) Check speed of tool at regular intervals.
21) Check always that the material to be sanded may not cause a risk by
being sanded, i.e. fire or explosion.
22) If self fixing discs are used, i.e. self adhesive or Velcro, always ensure
the disc is fixed centrally to the pad.
