Operating
Select a suitable abrasive belt of the required grade to achieve a fine
sanded finish or high metal removal. The belt size for this tool is 10 mm
wide x 330 circumference (continuous belt) and is available in various
grades, the lowest is grade 40 grit which is coarse for high material
removal and grits are available as 40, 50, 60, 80, 100 and 120. The
coarseness of the grit decreases as the grade number increases, hence
40 is coarse and 120 very fine.
To fit a belt, press down the tension bar and push the idle pulley towards
the tool until the tension bar clicks into place which releases the tension
and holds the tension off the belt. Fit the belt ensuring that it sits centrally
on the drive pulley and the idle pulley. Release the tension bar to tighten
the belt. Start the tool slowly and use the adjusting screw (8) to align the
belt centrally.
Apply the sander lightly to the work and allow the belt to cut. Take great
care when sanding around sharp edges and corners to avoid snagging
and belt damage or breakage. 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 tool has a low noise level, the actual sanding process may
create a noise such that hearing protectors should be worn.
If there are sharp edges on the material being sanded then safety gloves
are recommended.
Do not continue to use belts that are clogged or worn as this will make
the sanding process inefficient and the need to apply unnecessarily high
loads to the tool.
Only use belts of the dimensions specified. To use an incorrect belt will
either cause it to break or fly off. Both occurrences could be dangerous.
Dismantling & Assembly Instructions
Disconnect tool from air supply.
Press on the end of idle pulley (2) until it clicks into place and remove the
tension from the grinding belt (1). Remove screw (13) and take off shoe
(12). Unscrew idle pulley shaft and idle pulley (2) being very careful not
to lose the very small washer (3). Remove screw (8). Tap out one off pin
(10) and remove bracket (5) and spring (9). Unscrew socket head
screw (7) from bracket (10). Tap out pin (43) and remove tension bar
(40) and spring (41) and lever pin (42). Lever pin (42) can be tapped out
of tension bar (40) if a replacement is required. It is then possible to pull
out tension bar (6). Tap out a second pin (10) from tension bar (6).
Remove spring (11) from tension bar (6). Remove cap screw (15) and
rubber flap may be removed from guard (14). Tap out lever pin (30) and
remove throttle lever (29). Unscrew valve body (31) with valve stem
(35). Remove O-ring (33) from valve body (31) and O-rings (34) and
(36) from valve stem (35). Take out spring (37). Unscrew air inlet (39)
and take off deflector (38). Take off guard assembly (14) from housing
(18). Do not remove the brass bushing from guard assembly (14). It is
then required to remove end cap (23). This component is screwed and
glued in place. It is advised to apply local heat to the end cap (23) and
the part of housing (18) into which it locates to ease removal. Locate a
pin in the hole in the side of drive pulley (17) and grip it and with a socket
unscrew nut (16). Pull off drive pulley (17). Remove key (22). Tap the
end of rotor (28) to drive the motor assembly out of housing (18).
Remove front end plate (20) and bearing (19) and spacer (21) from
rotor (28). Take off cylinder (26) and remove 4 off rotor blades (27).
Support rear end plate (25) and tap non threaded end of rotor to drive it
through the rear end plate (25). Tap out bearing (19) from front end
plate (20) and bearing (24) from rear end plate (25).
Reassembly
Clean all parts and examine for wear and damage. Replace any parts
with parts obtained from the manufacturer or an approved
representative. Reassemble in the reverse order, fit belt and adjust.
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.
