FUNCTION
The machine is designed for sucking and separating dry, non-combustible dust with an
explosion limit value of >0.1mg/m3
The motor is started by the switch. Dust-laden air is then sucked through the inlet valve at high
speed via the suction hose. The air is slowed down by the cyclone and coarse dust particles
are separated out, partly by centrifugal force and partly be gravity. Air and finer particles then
pass through the main filter where separation is made. The machine is designed for filter
cleaning by reverse air pulse.
The separated dust accumulates in the cyclone until the machine is switched off, when it drops
through the bottom flap into the plastic bag.
USE
Before use, the user must be trained in handling the machine and the hazardous dust. Connect
theelectric plug to an outlet with the correct voltage (see designation plate). The filter must be
cleaned fromtime to time (see page 10). This must be done before changing the plastic bag
and can also be done when the work is complete or when there is poor suction.
REPLACING CANISTER BAG
IMPORTANT NOTE: Only original canister bags purchased from National may be used (see page
15)! Failure to follow these instructions will result in damage to

4. Remove canister from dust collector to access canister dust
collection bag.
5. Carefully lift debris filled bag from canister, securely close, and
properly dispose of.
6. Ensure residual debris has not fallen into canister. If so, clean canister throughly! Failure to
