Precautions and safety
regulations when using the
vacuum cleaner
When dust removers are used,
the rate at which air is ex­
changed in the room must be
adequate if the exhaust air from
the vacuum cleaner is blown into
the room (please observe regu­
lations valid in your country).
Before start-up
Inspect power cord regularly
to detect signs of damage, e.g.
cracks or ageing.
If the power cord is damaged,
it must be replaced by Makita­
Service or an electrician to avoid
danger before use of the vacuum
cleaner is continued.
Use only the type of power cord
specified in the operating manual.
Do not damage the power cord
(e.g. by moving over it or pulling
or crushing it).
Disconnect the power cord by
pulling the plug only (do not pull
or tug the power cord).
Inspect the vacuum cleaners to
ensure that they are in proper
condition. Plugs and couplings in
power cords must at least have
splash protection.
Never use the vacuum cleaner
if the filter element is damaged.
Picking up liquids
If foam develops or liquid emerg­
es, stop work immediately and
empty the dirt tank.
Regularly clean the built in float
to limit the water level and check
that they are not damaged.
See section 5 for information on
handling liquids and (hazardous)
dust.
Before starting work, the operat­
ing staff must be informed on
– use of the vacuum cleaner
– risks associated with the ma­
terial to be picked up
– safe disposal of the picked
up material.
Electrical components
Check the rated voltage of the
vacuum cleaner before connect­
ing it to the mains supply system.
Ensure that the voltage shown
on the rating plate corresponds
to the voltage of the local mains
power supply.
If you are using an extension
cord, use only those specified
by the manufacturer or higher
quality ones (see section 9.4
„Technical data").
It is recommended that the vacu­
um cleaner should be connected
via a residual current circuit
breaker. This stops the supply of
electricity if the leakage current to
earth exceeds 30 mA for 30 ms
or it has an earth tester circuit.
When using an extension lead,
check the minimum cross­sec­
tions of the cable:
Cable length Cross section
m
<16 A
up to 20 m ø1.5mm²
20 to 50 m ø2.5mm²
Arrange the electrical parts
(sockets, plugs and couplings)
and lay down the extension
lead so that the protection class
is maintained.
Never spray water on to the
upper section of the vacuum
cleaner. Danger for persons,
risk or short­circuiting.
Observe the latest edition of the
IEC regulations.
