1.2 Grounding Instructions
Thisoormachinemustbegroundedwhileinuse
toprotecttheoperatorfromelectricalshock.This
machineisbuiltwitha3-wirecordanda3-prong

groundedreceptacle.
Beforeusingthisoormachine,makesurea
properlygrounded,3-holeelectricaloutletis
available.Ifnotavailable,asinsomeolderfacilities,
useanadapterforconnectinga3-prongplugtoa
2-prongreceptacle(Figure2)togroundtheoutlet
chassis.
IMPORTANT: Thisadaptormaynotbeusedin
Canada.
IMPORTANT:Nevercutoffthegroundingprong
foruseina2-prongoutlet.Bydoingso,youhave
cutoffyourprotectionfromelectricalshock.
Neverassumethatall3-holeoutletsareproperly
grounded.Checkbeforeuse.
Neverassumethatanadaptorconnection(asin
Figure2)isproperlygrounded.Checktheoutlet

8.0 6-Quart Backpack Operation Instructions
PREPARATION AND OPERATION. DRY ONLY!
The 6-quart backpack is attached to the oor machine when shipped from the factory. No
assembly is required. This vacuum is equipped with an air-thru motor and is designed for
dry pickup only.
Getting Started:
Make sure your on/off switch is in the OFF position. Remove lid and check to make
sure you have both a cloth lter bag and paper lter bag in place. Secure lid back onto
the vacuum body, tightening securely. Both bags must be used at all times. Any damage
resulting from the lack of using both bags will not be covered under warranty.
To Change Paper Filter Bag:
1. Unscrew lid from body.
2. Remove full paper bag from the tank and dispose of
properly.
3. Take new paper lter bag and set inside cloth lter bag,
expanding it to the sides of the cloth lter bag.
4. Screw lid tightly back onto body.
Cloth Filter Maintenance:
The cloth lter should be inspected and cleaned each time you empty the tank. DO NOT
wash the cloth lter. It could cause shrinkage of the cloth and damage to the gasket.
Simply shake off any dust or loose particles and brush the exposed surface with a soft
bristle brush.

3.3 Transport:
Totransportthismachinefromthejanitor’sclosettothe
workarea:
• Lock the handle in the “up” position. Wind the cord
around the handles and the bottom cord hook.
• Tip the machine back onto the transport wheels. Push

any other part of the machine. Travel carefully.
4.0 Troubleshooting
Neveroperatethismachinewhentheequipmentisnotperformingasexpectedorwhen
anypartsarevisiblydamaged.Thecauseandsolutionforsomebasicproblemsare
describedbelow.Whenrepairisneeded,taketheequipmenttoanauthorizedrepair
servicecenter.
4.1 Machine will not Run:
• Circuit breakers are tripped in the building. Check and reset.
• Equipment is unplugged. Check plug at wall and at machine base. Plug in.
• Power cord failure. Test with a working power cord. Lock the handle up and tip the
motor back. Unplug the cord at the motor and plug the motor into your working
power cord.
IMPORTANT: this is just for testing! When you do this, you have removed the
safety handle controls from the circuit and you are sending power directly to the
motor. If the motor now spins, the problem is in the cord of the handle assembly. Seek
authorized repair service.
If the motor still does not work, the problem is either in the male connection at the
motor base or in the motor. Seek authorized repair service.
• Motor sparks or smokes. Seek authorized repair service.
4.2 Electrical Shock to Operator:
• Equipment wiring failure or electrical short in the machine. Seek authorized service.
• Poor grounding or no grounding. Test the outlet with a ground fault interrupter. Retain
certied electrician to inspect and repair grounding. NEVER clip off the ground plug
on your cord.
• Repeated circuit breaking. High amp draw and circuit breaking can be an electrical or
mechanical problem. Seek authorized repair service.
4.3 High Vibration:
• Pads are not centered on the pad driver. Tip machine back and re-center the pad.
• Uneven wear or warp to pad or brushes. Replace.
• Machine chassis is damaged by dropping. Replace.
