hose coupling into the intake opening until it stops.
Release the plunger pin.
• To remove; push in on the plunger pin, grasp the
coupling and pull.
Attaching Various Hoses
Hose cuffs may be difficult to attach when new. To ease
installation you may have to hold the hose cuff under
HOT tap water for 2 to 3 minutes to soften the hose cuff.
Squeegee Hose (if applicable)
• The end of the hose with the larger diameter cuff is
attached to the hose coupling by sliding it on. The
opposite end with the cuff that is smaller in diameter is
attached to the squeegee.
Super Flex hose with Swivel cuff for use with a wand
• The end of the hose with the larger diameter cuff is
attached to the hose coupling by sliding it on. The
opposite end with the cuff that is smaller in diameter
and movable is attached to the wand.
Install the Squeegee Assembly (if applicable):
• Place the squeegee lift arm in the storage (up)
position.
• The squeegee assembly mounts to the squeegee lift
arm using two (2) mounting knobs. Loosen the
mounting knobs and slide the squeegee assembly
onto the mounting plate.
• The squeegee assembly has two (2) small wheels to
prevent “rollover”. The roller wheels must be forward
of the squeegee assembly. Hand tighten the mounting
knobs. Do not use pliers to tighten.
• Do not add any weights or other pressure to the
squeegee mechanism. This will not improve the
performance and will shorten the life of the blades.
OPERATING THE MACHINE
To turn the machine on, flip the switch located on the
upper left corner of the rear of the machine base.
• When using the wand with the squeegee tool on
floors, the operator should drop his / her arm slightly to
allow air to enter the front edge of the tool on the
forward stroke. On the backward stroke the operator
should raise his / her arm slightly to allow the back
edge of the tool to clear the floor. This method gives
the air a chance to do the work in the most effective
manner.
• The operator should make strokes at a leisurely pace
and at a length that feels the most natural.
• Always work away from the machine, pulling the
machine behind you.
Dry Pick Up
• Clean or replace the filter bag when suction is
reduced.
• Choose the proper wand and tool
• Use a paper bag to make disposal easier.
Wet Pick Up
The Micro Filter Assembly, HEPA Assembly, or Filter
Bag may be used when picking up liquids. The Filter
Bag helps prevent debris and foam from being pulled
into the vacuum motor and fans, causing motor damage
and possible failure.
• The motor will speed up and sound different when the
airflow is closed off.
