Harness Assembly:
Remove four (4) screws from vacuum housing inserts. Position harness
on vacuum housing. Align harness back plate with mounting holes to the vacuum body. Re-
insert four (4) screws through harness and tighten.
Adjusting Backpack Harness:
Loosen waist and chest belt latches. Slide arms through shoulder straps. Adjust
shoulder straps to raise or lower backpack so that the weight is evenly distributed between the back and hips, and the
waist and chest belt latches comfortably. For significantly shorter or taller operators, it may be necessary to adjust the
harness back-plate to find a comfortable position. The back-plate can be re-positioned by removing and relocat ing the
four (4) screws to the vacuum housing.
To Operate:
(
1) Pass the pigtail cord through the strap outside the left side of the waist belt. Pass your exten-
sion power cord (not provided with vacuum) through the plastic retaining clip hanging from
the harness. This will prevent the pigtail and extension power cord from separating during
operation.
(2) Place the pigtail switch box under the sewn strap and fasten the other strap around
the switch box.
(3) Fasten the waist belt and chest belt snugly and make sure the weight is resting com-
fortably on your hips. Again, the back plate is adjustable up or down by removing the
four screws that attach to the vacuum’s body.
(4) To attach battery holster to harness, fasten two (2) chrome clips located on top of holster to eyelets located on
left side of harness belt. Battery holster should be positioned on operator’s left hip/thigh area and secured using
Velcro strap around thigh.
(5) Connect the two (2) Anderson electrical connectors (blue) to deliver battery power to the backpack unit. Use the
rocker on/off switch on the pigtail switchbox to activate vacuum motor.
(6) Plug the charger into an appropriate outlet before connecting the battery pack to charger. Each
lithium battery will take approximately 3 hours to fully charge. Press button on battery pack to
show status of battery life. The completion of charge is indicated by four (4) green LED lights. Re-
charge discharged batteries as soon as possible after use or battery life may be greatly diminished.
For longest battery life, do not discharge batteries fully.
Thermal Protection:
The motor in this vacuum is protected with a thermal cutoff device. If an excessive
high op erating temperature is detected, power to the motor will be cutoff. Excessive operating temperature
can be caused by a blocked vacuum hose or clogged filters. If thermal cutoff occurs, immediately turn off the vacuum
and inspect for hose blockage or full filter bag. Remove blockage and/or replace filter bag, then allow a few minutes for
the vacuum to cool down to reset thermal cutoff device before turning vacuum on.
