Safe Operating Conditions

READ THIS MANUAL BEFORE USING BURNISHER. KNOW THE PROPER OPERATION, CORRECT APPLICATIONS AND THE LIMITATIONS OF THIS EQUIPMENT BEFORE USE.

Reduce the Risk of Fire, Electric Shock or Injury:

• This burnisher is designed for indoor use only. Do not use outdoors. Do not expose to rain.

• Do not wash the motor with flowing water. If the motor gets wet, seek authorized service.

• Keep the vents on this air-cooled motor free from debris.
  Do not operate with the motor covered or with vents blocked. Do not use this machine as a floor sander.

• Never operate this machine near flammable dusts, liquids or vapors. Never use flammable solvents as a cleaning agent. Engine sparks and operating heat can cause fire.

• Never handle electrical equipment with wet hands. Never operate this machine with bare feet.

• Unplug the machine when not in use and when servicing the equipment. To unplug, grasp the plug not the cord.

• Do not operate a burnisher with damaged handle controls, cord or plug. If the equipment is not performing properly, seek repair from a qualified service supplier.

• This machine is constructed with electrical grounding at the plug. Operate only when connected to a properly grounded outlet. See section 1.2 for grounding details.

• Prevent electrical cord abuse. Do not close a door upon the cord, drive equipment over it, or run the floor machine over it. Do not expose the cord to hot surfaces.
  Do not lift, pull or carry this burnisher by the cord.

• Never operate the machine over sharp objects that can be thrown out and harm the operator and damage the floor.
  Sweep hard floors before scrubbing or buffing. Vacuum clean carpets before shampooing or bonnet cleaning.

• Train your staff in proper use of this machine.

1.1 Electrical Power
This burnisher operates on a 13 amp nominal 115 V, 60 Hz, A.C. power circuit. (Motors may be custom wired at the factory for 220 V, 50 Hz international operation). The amp, hertz and voltage ratings are listed on the motor spec label found on each burnisher.
Using voltages above or below those indicated on the spec label will damage the motor. Always check your local voltage requirements.

1.2 Grounding Instructions
This burnisher 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 grounding-type plug (Figure 1) to fit a properly grounded receptacle.
Before using this burnisher, 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 with a ground fault interrupter device which quickly indicated if a ground is connected. Correct a faulty grounding before proceeding.

1.3 Extension Cords are Not Recommended
The burnisher is built with a 50 foot (15 M) safety cord which plugs directly into an approved outlet. Use of any extension cords is NEVER RECOMMENDED.

 Mount the Handle

This burnisher is shipped from the factory with the handle unattached. You will need two 7/16” wrenches to complete the assembly.
Remove the handle and mounting hardware from its carton. Bolts, nuts, washers and the locking lever assembly are in the plastic bag attached to the handle.

1.  Mount the handle to the chassis: Align the handle with the yoke (1) over the mount (2) on the burnisher chassis. The power cord will be facing away fro the motor. Place a flat washer (4) on a 3” bolt (3), then place the bolt through the holes in the yoke and the mount. Place another washer on the bolt and secure with the locking nut (5). Tip the handle back and out of your way for the next step.

2. Mount he support braces on the handle:
   Tip the handle up. The handle mounting collar (7) is designed to slide freely up and down the handle tube, allowing the handle to be adjusted for the comfortable operation of all users. Line up the mounting collar with the upper holes in the two straight handle braces (6).
   • Place the curved spacer (12) with a square hole onto the locking lever shaft (11). The curve must face the lever.
   • From behind the machine, insert the shaft through the right handle brace (6), the mounting collar (7) and the left handle brace.
   • Place a spacer (9) on the shaft.
   • Place the split washer (13) on the shaft.
   • Place the locking wing nut (14) on the shaft.
   • Adjust the wing nut for tightness. When correctly installed, the collar slides easily when the cam-engineered locking lever is “up,” but is firmly fixed wen the lever is “down.”

2.1 Attach the Power Cord
The triple-wire grounded power cord has been factoryinstalled into the handle tube. A flexible rubber cable connector (11) is used to secure the plug-in connections.The burnisher ships with this connector mounted on the cord coming out of the handle (10).
Stretch the connector and slip the male connector (9) (coming out of the motor housing) through the connector hole and then into the female connector. Now, plug the end of the 50-foot cord into a grounded power outlet. Squeeze the triggers on the handle and check for power to the motor.

2.2 Inspect the Pad Driver
A flexible, high-speed pad driver has been bolted onto the burnishing machine and dynamically balanced. This driver is the connection between the burnisher and a disposable pad that burnishes the hard floor finish. If this molded plastic part ever becomes damaged or if the molded hooks are worn and cannot hold the pad, replace promptly. Unplug the burnishing machine. Lock the handle in the “up” position and tip the machine back fully. Remove the 4 mounting screws (11) and washers (12) from the drive hub (13). Place the new pad driver (14) onto the main drive pulley. Insert the mounting screws (11) through the washers (12) into the bolt hole. Tighten securely.

2.3 Install the Pad
The face (bottom) of the pad driver (14) is covered with small “hooks” that grab onto the pad (16). Every time you mount a new pad onto the pad driver, follow these steps:

• Unplug the burnishing machine. Lock the handle in the “up” position and tip the machine back fully.
• Pad Sizes: 20” diameter pad on the 20” and 21” machines. Mount a pad (16) over the male shoulder (15) on the pad driver. Make sure that the pad is centered on the driver.
• Insert the locking ring (17) through the center hole in the pad and into the shoulder. Tighten until the locking ring lies below the face of the pad. If the ring is not fully locked, it will scratch the floor.

NEVER operate the burnisher without a pad.
NEVER operate the burnisher with a damaged pad of without a locking ring to hold the pad in place.

2.4 Adjust the Front Wheel Assembly on 2000 RPM Model
The 2000 RPM model is designed with a front wheel assembly that controls the down pressure that the pad applies to the floor. Raise the apron height to reduce the down pressure. Lower the apron height as the pad wears. The warranty on a 2000 RPM machine will be voided if the machine is operated without this wheel assembly in place and operating correctly.

Operating Tips

• For indoor use only. Sweep abrasive soils before burnishing.
•  While the pad driver is spinning, keep the burnisher moving to avoid “donut” burns on the floor.

To Start Operation:

•  Unlock the handle by raising the locking lever.

• Lower the handle to a comfortable position, typically waist high.

• Relock the handle by pushing the lever down. NEVER OPERATE THE MACHINE WITH THE HANDLE UNLOCKED.

• This burnisher has a high torque motor.

•  Hold the machine firmly with both hands when starting up.

• Push the red safety interlock switch forward to unlock the dual triggers.

• Squeeze both triggers to power the motor. Once power is on, either trigger will keep power to the motor. To stop, release both triggers.

3.1 To Store your Machine

• Lock the handle in the “up” position. Tilt the machine back onto the transport wheels. Never store the machine with the pad on the ground.

• Wind the cord around the handles and the bottom cord hook.

•  Wash pads and hang to dry.

• Inspect and maintain equipment on a regular schedule for best results.

• Check and clean pads after each operation. Remove soil and chemical buildup. Replace worn or damaged pads.

• Check the triggers and switches for proper operation.

• Use air pressure or vacuum to remove dust and debris from the motor vents.

• Report problems and repair promptly.

3.2 Transport
To transport this burnisher 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 or pull the machine by the handle, not by the cord or any other part of the machine. Travel carefully.

Troubleshooting

Never operate this burnisher 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 Burnisher will not Run

• Circuit breakers are tripped in the building. Check and reset.
•  Equipment is unplugged. Check plug 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 spin, 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 certified 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.
