6. Operating Instructions
Vacuuming
Before starting a vacuuming process,
•
make sure the machine is properly connected to a grinder or a floor tool via the
provided hose and fittings.
•
chek the power cable and the plugs are in a good condition.
•
make sure the power voltage corresponds to that on the rating plate and connect
correctly the power plug to a power socket
Turn on the power switch to start a vacuuming process.
During the vacuuming process, dust-laden air is sucked through the flexible hose and inlet
valve at a high speed. The air is then slowed down by the cyclone, and coarse dust particles
are separated out partly by centrifugal force and partly by gravity. Air and finer particles pass
through the pre-filter at the first and the HEPA filter at the final stage where separation is made.
Filter Cleaning
The machine is designed for filter cleaning by reverse air “jet-pulse”.
The filter must be cleaned from time to time. This must be done before changing the bag
collection system and should also be done when work is completed or whenever there is a poor
suction.
Filter cleaning procedure:
1) Cover the inlet by lifting up the inlet valve and let the machine build up vacuum for 4
to 5 seconds,
2) Quickly push down the filter cleaning handle and release it. Repeat the procedure
five times. It is important to let the machine rebuild the vacuum in between every
repetition,
3) Open the inlet again by pushing down the invlet vavle.
If suction remains poor, the conical pre-filter needs to be replaced. If suction still
remains poor afterwards, the HEPA filters needs to be replaced. See instructions in the
next chapter.
