Call the Nilfisk dealer named below for repair parts or service. Please specify the Model and Serial Number when discussing your machine.

(Dealer, affix service sticker here.)

NAME PLATE

The Model Number and Serial Number of your machine are shown on the Nameplate on the bottom of the machine. This information is needed when ordering repair parts for the machine. Use the space below to note the Model Number and Serial Number of your machine for future reference.

MODEL NUMBER

SERIAL NUMBER

UNCRATE THE MACHINE

When the machine is delivered, carefully inspect the shipping carton and the machine for damage. If damage is evident, save the shipping carton so that it can be inspected. Contact the Nilfisk Customer Service Department immediately to file a freight damage claim (phone number is provided on the back cover of this manual).

PREPARED THE MACHINE FOR USE

WARNING!

Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe injury if allowed to contact the skin or eyes. Explosive hydrogen gas is vented from inside the batteries through openings in the battery caps. This gas can be ignited by any arc, spark or flame.

WHENServICINGBATTERIES....

• Remove all jewelry
• Do not smoke
• Wear safety glasses
  Work in a well-ventilated area
• Do not allow tools to touch more than one battery terminal at a time.

CAUTION!

Electrical components in this machine can be severely damaged if the batteries are not installed and connected properly. Batteries should be installed by your local Nilfisk dealer or by a qualified electricain.

The UHB 51-1500 may be used with three 12 volt 185 amp hour batteries or three 12 volt 234 amp hour AGM batteries.

CAUTION!

The battery charger must be reprogrammed when switching from lead acid to AGM batteries. See the Charger Manual for instructions.

PREPARED THE MACHINE FOR USE

(B)-INSTALLING THE BATTERIES

1 Carefully lift the batteries into the battery tray. Arrange as shown in Figure B.

B

2 Make sure the key switch is in the OFF position.
3 Install the battery cables as shown in figure B, with the terminals marked "P" on the positive battery posts and the terminals marked "N" on the negative battery posts. Position the cables so that the caps can be easily removed when it is necessary to add water to the batteries.
4 Tighten the nut on each battery terminal just enough to keep the terminal from being turned on the battery post. Then tighten the nut one more full turn.
5 Coat all the terminals and posts with grease, petroleum jelly or spray-on battery coating (available at most auto parts stores).
6 Put on the black rubber "boots" over each of the terminals and use the plastic tie straps to hold them in place.
7 Join the connector from the battery pack to the connector on the control panel.
8 Reassemble machine.

NOTE: Charge the batteries before using the machine.

(C)-PAD INSTALLATION

Your local Nilfisk distributor can provide the proper pads and floor finishes for use with this machine.

CAUTION!

Using the wrong kind of pad on this machine can damage the floor. The pad must be centered properly on the pad holder to prevent machine vibration.

For pad installation, follow the steps below (see steps 1 - 6 in Figure C):

1 Turn the key switch off.
2 Put the machine in the position shown, to access the pad retainer.
3 Go to the front of the machine. While holding the pad retainer with one hand, rotate the pad and pad driver counter clockwise to loosen the pad retainer.
4 Remove the old pad and install a new one, being careful to center it on the pad driver.
5 Retighten the pad retainer as tight as possible.
6 Raise the back of the machine to lower the pad housing by lifting as shown.

(D)-DUST BAG INSTALLATION

Your local Nilfisk distributor can provide the proper pads and floor finishes for use with this machine.

IMPORTANT!

Install dust collector bag (part number 56201569) on top of control housing (see Figure D). The dust collection system will not operate properly if the collector bag is full or torn.

(E)-ADJUSTING PAD PRESSURE

The pad pressure is set at the factory for optimal burnishing with most pad and finish combinations. If unique pad or finish conditions require pad pressure adjustments, adjust by following the procedure below. NOTE: Pad pressure adjustments should be performed by a qualified service technician.

1 Turn key switch off (O).
2 From underneath burnisher, loosen jam nut (A).
3 To decrease pad pressure, turn bolt (B) clockwise.
4 To increase pad pressure, turn bolt (B) counterclockwise.
5 Re-tighten jam nut (A).

BATTERY MAINTENANCE

Charge the batteries each time the machine is used for 1 hour or longer, or whenever the Battery Meter reads in the red area.

To Charge the Batteries...

1 Remove cover.
2 Plug charger in.
3 Check the fluid level in all battery cells after charging the batteries. Add distilled water, if necessary, to bring the fluid level up to the bottom of the filler tubes.

CAUTION!

To avoid damage to floor surfaces, wipe water and acid from the top of the batteries after charging.

CAUTION!

Acid can spill onto the floor if the batteries are overfilled.

IMPORTANT

Motor damage resulting from failure to service carbon brushes is not covered under warranty. See the Limited Warranty statement.

TROUBLESHOOTING

MACHINE VIBRATION

1 Pad is not centered properly.
2 Defective pad. Replace.

SWIRL MARKS

1 Pad is too aggressive for the floor finish.
2 Pad is dirty, Check and replace.

REDUCED RUNNING TIME

1 Battery needs to be charged.
2 Batteries need water. Add just enough to cover the plates in each cell. Then charge the batteries and check the water level again.

(E) PAD ASSIST MACHINE DOES NOT PULL ITSELF

For pad assist adjustment, follow the steps below (see steps 1 - 6 in Figure E):

Tip burner back as shown to gain access to the pivot bracket.
2 Remove the dust bag.
3 Pull down on the dust skirt to gain access to the adjustment hardware.
4 Lossen pivot bracket adjustment hardware and pivot bolts and rotate bracket counterclockwise to increase pad assist.
5 Pivot brakethas slots to allow adjustment.
6 Adjust pivot bracket so pad is tipped down towards the RH side of the machine to increase the pad assist. Then retighten the adjustment hardware.

CAUTION!

Pad assist will vary depending on the aggressiveness of pad and the floor finish. If the deck is angled too much it could result in the pad burning the floor on the RH side.
