How to assemble and use
Follow these simple steps for easy and
effective operation of the Backpack vacuum.
Open the lid and ensure that the cloth bag is
correctly located and the flexible ring provides
a proper seal when the lid is closed. For
optimum performance, filtration and maximum
hygiene, it is advisable to use a paper vacuum
bag in addition to the standard cloth bag.
• Push vacuum hose into the cuff in the lid
(Fig.1). It should not be necessary to remove
the hose in normal operation.
• Place the Backpack vacuum on your back,
adjust the shoulder straps until you feel
comfortable and then tighten the waist belt.
The Backpack vacuum is designed to ride
higher on your back for maximum comfort
(Fig. 2).
• Attach hose, wands and floor tool (Fig. 3
and 4). To attach floor tool, loosen lock nut at
the end of the wand, slide on tool, then
tighten lock nut.
• Turn the vacuum on. The switch is located on
the switch box. The switch box can be
secured to the waist belt (Fig. 5). It has 2
modes: NORMAL power and MAX power
(Fig. 6).
• After you finish cleaning, turn off the main
power switch before removing the Backpack.
