UNPACKING

When unpacking the machine, please check that the following accessories are included:
• The hose with end fittings
• Handle
• Floor nozzle
• Extra bags
If any of the above mentioned parts are missing, please contact your distributor or our sales
representative. Assemble the front wheels using the using bolt, washer and nut that are
included in the package.

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.

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
