Work Stations
The tool should only be used as a hand held 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 the safety rules to be obeyed when using the sander.
Foreseen Use of the Tool
The tool is designed for the purpose of cleaning or sanding of
materials using a continuous abrasive belt. Belts are available in
various grades to suit fine finishing or fast material removal.
Do not use the tool for any other purpose than that for which it was
designed. Do not modify this tool for any other use or for its use as a
belt sander without first consulting the manufacturer or the
manufacturer’s authorised distributor.
Putting Into Service
Air Supply
Use a clean lubricated air supply
that will give a measured air
pressure at the tool of 90 p.s.i./6.3
bar when the tool is running with
the trigger/lever fully depressed.
Use recommended hose size and
length. It is recommended that the
tool is connected to the air supply
as shown in figure 1. Do not
connect the tool to the air line
Tel No Fax No(01494) 883300 (01494) 883237
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 equipment can be obtained from your supplier. If
such equipment is not used then the tool should be lubricated by
shutting off the air supply to the tool, depressurising the line by
pressing the trigger on the tool. Disconnect the air line and pour into
the intake bushing a teaspoonful (5ml) of a suitable pneumatic motor
lubricating oil preferably 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.

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.
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 20
mm wide x 525 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 (2A) 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 belt at idle pulley (2) position towards tool and idle pulley
bracket (1) will click into a holding position taking the tension off of the
belt to allow the belt to be taken off. Note that a new belt is fitted in
a similar way and tension bar (14) is pressed after the belt has been
fitted to tension the belt. With a screwdriver located in the idle pulley
assembly (2) unscrew nut. Unscrew hexagon socket head bolt (2A).
Remove finger pad assembly (4) by removing holding cap screw.
Remove hexagon socket head bolt (6) and take off flat shoe (10).
Remove key bolt (5) and drive out lever pins (16) and (17) and take
out tension bar (14) and spring (15). Pull out idle pulley bracket (1) and
spring (3). Grip drive pulley (9) and unscrew bolt (8) with washer (8A)
and prise off drive pulley (9) with key (22).Pull out dust cover (12).
Unscrew bolt (11) and slide off guard body (13). Grip housing (18)
and unscrew cap (23). Tap the end of rotor (28) to drive the complete
motor assembly out of the end of housing (18). Grip end plate (20)
and insert a punch into the threaded hole in rotor (28) and tap the
punch to drive the rotor (28) through end plate assembly (20). Take
off cylinder (26), spacer (21) and 5 off rotor blades (27) (one set) from
rotor (28). Locate end plate (25) on the cylinder side and tap the end
of the rotor to drive it though end plate (25) assembly. Tap out bearing
(19) from end plate (20) and bearing (24) from end plate (25). Drive
out pin (30) and remove lever (29). Unscrew air inlet with screen (39)
and take off deflector (38). Unscrew valve body (31) and take out
O-rings (32) (33) (34) and (36), valve stem (35) and valve spring (36).
Reassembly
Clean all parts and examine for damage and wear. Replace any part
with parts obtained from the manufacturer or an approved
representative. Coat all parts with a pneumatic tool lubricating oil and
assemble in reverse order. Fit new belt - see section Operating.
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.
