MAINTENANCE
Before use, check to ensure that all parts are serviceable, including the air inlet
hose, rubber gloves and abrasive pick-up.
Ensure the air vent foam filter is in place.
The swivel clamps, securing the lid, must be secure so as not to allow the lid to
open during operation. The build up of air pressure within the cabinet could force
the lid open, allowing abrasive to escape. This is not only wasteful, but could be a
health hazard.
Ensure the filters are serviceable and seated correctly.
Ensure you comply with all precautions regarding the use of compressed air, and
air compressor operation.
Changing the Fluorescent Tube
Ensure the transformer is disconnected from the power supply before opening
the lid and cutting the two ties securing the lamp to its retaining clips.
Carefully pull the lamp from its retaining clips then hold the clear plastic protective
outer tube firmly and ease off the plastic end cover from the non-wired end. (This
may take a little persuasion and perseverance).
Once the end cover has been removed, hold the end cover at the opposite end
(the cable input end), and pull off the outer protective clear plastic tube.
The fluorescent tube is now fully revealed.
Pull off the end connector, which secures a wire to one of the pins, taking care
not to distort the aluminium reflector. Then pull off the wire secured by a plastic
sheath to one of the pins at the cable input end.
Assemble in reverse order, ensuring the wires are correctly held by the plastic
sheath at one end and the end connector at the other, with the reflector correctly
in position.
Replace the assembly into its retaining clips and test its operation by plugging the
transformer in to the mains.
