INSTALLING THE BATTERIES

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.

WHEN SERVICING BATTERIES...

• 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!

Acid can spill onto the floor if the batteries are overfilled.
To avoid damage to floor surfaces, wipe water and acid from the top of the batteries after charging.
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-Advance Distributor or by a qualified electrician.

1 When fitting or replacing the batteries from their shipping crate, carefully inspect them for cracks or other damage. If damage is evident, contact

the transport company that delivered them or the battery manufacturer to file a damage claim.

2 Make sure the machine’s Key Switch (Main Power) (4) is in the OFF position and the Emergency Quick Disconnect (1) is depressed.
3 Remove both Battery Compartment Covers (30).
4 Using (2) people and an appropriate lifting strap, carefully lift the batteries into each battery compartment and arrange them exactly as shown.
5 Install the battery cables as shown (Red (A) is Positive / Black (B) is Negative). Position the cables so the battery caps can be easily removed

for service.

6 Carefully tighten the screw and nut on each battery terminal until the terminal will not turn on the battery post (min. 70 in lbs).
7 Coat the terminals and posts with a high temperature grease, or spray-on battery terminal coating (available at most auto parts stores).
8 Put one black rubber boot over each of the terminals and secure with a tie strap.
9 Plug the yellow battery connectors from the batteries into the matching yellow connectors on the chassis on each side.

OPERATING THE MACHINE

______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

SWEEPING

Follow the instructions in preparing the machine for use section of the manual.
1 Turn the Key Switch (4) ON. Pull the Main Broom Raise / Lower (ON/OFF) Lever (15) back and slide to the left and up to lower and start the

main broom. NOTE: The brooms will not turn on if the hopper door is closed.

2 When sweeping dry floors, turn the dust control system ON by pushing the Dust Control / Shaker Switch (6) up to the permanent ON position.

When sweeping floors with puddles, put the Dust Control / Shaker Switch (6) in the neutral or OFF position
puddle. Turn the Dust Control / Shaker Switch (6) ON when the machine is back on a completely dry floor.

When sweeping wet floors, keep the Dust Control / Shaker Switch (6) in the OFF position. (This will prevent moisture from getting into the
Hopper Dust Control Filter (20)).

3 Lower the Side Broom (36) by pushing the Side Broom Raise / Lower (ON / OFF) Lever (23) down to the right and up for sweeping along a

wall or curb. Raise the side broom when sweeping in an open area.

4 Drive the machine forward in a straight line at a quick walking speed and overlap each pass approximately 6 inches (150 mm). Drive the

machine slower when sweeping large amounts of dirt or debris or when safe operation dictates slower speeds.

5 When sweeping extremely dusty floors, it may be necessary to stop sweeping occasionally and shake the Hopper Dust Control Filter (20).

To shake the filter, push the Dust Control / Shaker Switch (6) down to the momentary ON position, and hold for 20 seconds. Push the switch
back up to the permanent ON position to activate the dust control impeller and continue sweeping.

6 Check behind the machine occasionally to make sure that the machine is picking up debris. Dirt left behind in the path of the machine usually

indicates that the machine is moving too fast, the broom needs to be adjusted, or the hopper is full. NOTE: If there is debris on the floor too
large to be swept up, open the Litter Door (39) and throw it into the hopper.

NOTE: The main and side broom, dust control and shaker motor will turn OFF automatically and cease to function after the batteries reach an 80%
depth of discharge. Normal function will return to the brooms when the batteries are re-charged.

5 Slowly drive the machine forward until the hopper is over the receptacle and apply the Parking Brake (24).
6 Push the Hopper Door Open / Close Lever (17) forward until the hopper door is completely open. Once all of the debris has emptied out, close

the hopper door. NOTE: The Dust Control / Shaker Switch (6) may be left ON while dumping to draw some of the dust through the Hopper
Dust Control Filter (20). This is effective when dumping onto the ground or onto a pile.

7 Put the Hopper Safety Support (37) in place by pulling up on the Hopper Safety Support Pull Rod (41), then lower the hopper slightly to secure.
8 Look for an accumulation of litter on the back of the hopper and on the front of the broom housing. Use a broom, if necessary, to remove litter

from these areas. The back of the hopper must seal tightly against the front of the broom housing for proper operation.

9 Return to the operator’s compartment. Release the parking brake. Move the machine back until the hopper will clear the receptacle. Raise

the hopper slightly until the Hopper Safety Support (37) disengages, then lower the hopper. and re-open the hopper door. NOTE: The brooms
will not turn on if the hopper door is closed.

______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

MAIN BROOM MAINTENANCE

Since the Main Broom Motor always turns in the same direction, the bristles on the broom eventually become curved, reducing sweeping
performance. Sweeping performance can be improved by removing the broom and turning it around (end-for-end). This procedure, known as
“rotating” the main broom, should be done once every 30 hours of operation.

The main broom should be replaced when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom stop must be re-adjusted
when the broom is replaced.

NOTE: The machine should be stored with the Main Broom in the raised position.

WARNING!

Turn the Key Switch (Main Power) (4) to the OFF position and disconnect the batteries before performing this procedure.

To Rotate or Replace the Main Broom...
1 Turn the Key Switch (4) OFF and depress the Emergency Quick Disconnect (1).

2 Put the Main Broom Raise / Lower (ON / OFF) Lever (15) in the DOWN position.
3 Open the Main Broom Access Door (33) by releasing both latches and pulling the door outward before swinging it open.
4 Remove the large T-Bolt from the side of the broom idler arm. Pull the idler arm assembly out of the main broom core.
5 Pull the main broom out of the broom housing and remove any string or wire wrapped around it. Also inspect the skirts at the front, back and

sides of the broom housing. The skirts should be replaced if they are torn or worn to a height of more than 1/4 inch (6.35 mm) off the ground.
6 Turn the broom around (end-for-end) and slide it back into the broom housing. Make sure that the lugs on the broom drive hub (left side) engage

the slots in the broom core.
