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.

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.

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,
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 bar.

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 runn ing with the trigger/le ver 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 system without

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 th e tool until the te nsion 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 a re sharp edges on th e material being sa nded 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 brac ket (1) will click into a holding position tak ing the
tension off of the belt to allow the belt to be taken off. Note that
a ne w belt is fitted in a s imilar way an d 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.
Unscre w hexagon sock et head bolt (2A). Remove finge r 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 k ey (22).Pull out dust

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

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
