Specific Safety for Dust Extractors
DO NOT
use this machine as a vacuum cleaner,
try to keep the waste medium to wood by
products. Do not uplift workshop floor debris
(stones, nails, screws, paper etc., etc).
Be aware that wood dust is an explosive
medium.
DO NOT
allow any ‘naked light’ source to
occur anywhere near the machine. This
includes cigarettes, matches, etc, and do not
place the machine near any unprotected light
bulbs, that could possibly get broken.
The suction force is generated by a high
speed fan unit. This has the potential to
amputate fingers, grab loose clothing (ties
etc.,) and ‘bat’ large chips etc, at high speeds.
Keep all guarding in place, and if access to the
fan becomes necessary (due to blockage etc.,)
disconnect the machine from the mains supply
and ensure the fan has come to a complete
stop before putting your hands anywhere near
to it.
If you are not using ‘clear’ extraction hose,
periodically remove the hose to check that the
inlet to the machine is not getting restricted.
(The safety guard grill of the inlet duct can be
particularly irksome in this way, as long strand
shavings etc., can wrap around the grill fret.)
Keep the dust bag clean. The machine relies
on its ability to ‘blow’ air through the dust bag,
to generate good suction. If the cloth of the
bag starts to clog, this reduces the air flow and
hence the machine becomes less efficient. (A
good indicator is the speed at which the bag
inflates and how firm it feels; quick inflation
and a very firm feel means that the bag is
clogged and the air is having difficulty passing
through the cloth).
The bag can be cleaned, but one of the
simplest methods is to turn the bag inside
out, and beat it as though it were a carpet.
Similarly, empty the bag as often as possible
(and is practical); as the bag fills up there is
less free area of the bag to allow the air to flow
through, again reducing the efficiency of the
machine.
Be aware that in dry air periods or areas, the
movement of the air through the machine can
generate static electric fields. These are not
normally a problem as the machine is bonded
together via its construction, and the whole is
earthed back through the electrical supply;
problems can occur with isolated items, such
as stands or hosing that are insulated from the
ground (standing on rubber feet?, suspended
in the air? etc).
If possible, try to connect everything together
electrically, to eliminate static shocks.
(Use the integral metal coil in flexible
plastic hosing to connect units together)
Try to route the power cable and the hosing
away from busy walkways.
DO NOT
allow the inlet to become ‘dead
ended’, or block or restrict the outlet, this puts
undue work on the motor and can lead to
overheating.
NOTE!!
