CONVENTIONS Forward, backward, front, rear, left or right are intended with reference to the operator’s position, that is to say with the hands on the handlebar (10). UNPACKING/DELIVERY CAUTION! To unpack the machine, carefully follow the instructions on the packing. Upon delivery carefully check that the machine and its packing have not been damaged during transportation. In case of visible damages, keep the packing and have it checked by the carrier that delivered it. Call the carrier immediately to ll in a damage claim. Check that the machine is equipped with the following features: – Technical documents:

• Sweeper User Manual (the present document)

• Electronic Battery Charger Manual

• Sweeper Spare Parts List – No. 1 5 A fuse SAFETY The following symbols indicate potentially dangerous situations. Always read this information carefully and take all necessary precautions to safeguard people and property. The operator’s cooperation is essential in order to prevent injury. No accident prevention program is effective without the total cooperation of the person responsible for the machine operation. Most of the accidents that may occur in a factory, while working or moving around, are caused by failure to comply with the simplest rules for exercising prudence. A careful and prudent operator is the best guarantee against accidents and is essential for successful completion of any prevention program.

2. Close the battery and main motor hood (21) and engage the front latch (22).

3. Insert the ignition key (2) on the control panel and turn it to “I” without pulling the drive control lever (8).

If the green LED (4) turns on, the batteries are ready to be used. If the yellow or red LED (5 or 6) turns on, the batteries must be charged (see the procedure in Maintenance chapter). b) Without batteries

1. Buy appropriate batteries (see the Technical Data paragraph and the

diagram in Figure 1). For battery choice and installation, apply to qualied battery Retailers.

2. Disengage the front latch (22) and open the battery and main motor hood

3. Ensure that the battery connector (36) is disconnected.

WARNING! The installed batteries may require a specic charging algorithm: to set the most appropriate charging algorithm for the installed batteries, always contact a qualied Nilsk Service Center.

4. Carefully lift the batteries to the relevant compartment, then place them as

5. Route and install the battery cable as shown in the diagrams in Figure 1,

then carefully tighten the nut on each battery terminal.

6. Place the protection cap on each terminal, then connect the battery

7. Close the battery and main motor hood (21) and engage the front latch (22).

STARTING AND STOPPING THE MACHINE

Starting the machine

1. Insert the ignition key (2) on the control panel and turn it to “I” without pulling the drive control lever (8).

During the rst 3 seconds, the battery LEDs (4, 5 and 6) ashing indicates the type of battery installed. Then, if the battery charge is sufcient, the main motor (44) turn on the main broom (27) and the vacuum fan (48). If the green LED (4) turns on, the batteries are ready to be used. If the yellow or red LED (5 or 6) turns on, the batteries must be charged (see the procedure in Maintenance chapter). WARNING! The machine cannot be started when the hopper (14) is not its position. A safety system prevents it from starting.

2. Lower the side brooms (18) and (19, optional), by pulling the levers (12) and (13, optional) backwards.

NOTE The side brooms turn on when lowered and can be lowered and lifted even when the machine is moving.

3. Start sweeping by grasping the handlebar (10) and pulling the drive control lever (8) gradually.

Stopping the machine

1. Drive the machine to the work area as shown in the previous paragraph.

2. Avoid stopping for a long time with the machine in the same position and the brooms turning: this could create unwanted marks on the oor. 3. For machine proper operation, the dust lter (41) must be as clean as possible. For cleaning it while sweeping, turn on the lter shaker by pressing the switch (3) for a few seconds. During this procedure the main motor and all functions are automatically cut-off. NOTE Repeat the lter shaking procedure at least every 10 minutes. This interval can change depending on the dustiness of the area to be cleaned. NOTE When the dust lter is clogged and/or the hopper (14) is full, the machine cannot collect dust and debris anymore.

4. When operating on wet oors, open the “wet by-pass” port (43) to avoid damaging the dust lter.

When operating on dry oors, close the “wet by-pass” port (43) to restore proper vacuuming.

5. The hopper (14) should be emptied after each working cycle and whenever it is full.

NOTE When the hopper is full, the machine cannot collect dust and debris anymore.USER MANUAL ENGLISH 1465366000 - SW900 13 HOPPER DUMPING

1. Stop the machine and turn the ignition key (2) to “0”.

2. Remove the hopper (14) by using the transport handle (15) and the wheels (16) to drag it at the waste collection centre, then empty it.

BATTERY CHARGER CABLE CHECK

Carefully check the battery charger cable (38) and the relevant plug for wear, cuts, cracks or other damages. If the battery charger cable or the relevant plug is damaged, contact the Nilsk Service Center. BATTERY CHARGING CAUTION! Charge the batteries when the yellow (5) or red LED (6) turns on, or at the end of each cleaning cycle. Keeping the batteries charged make their life last longer. WARNING! When the batteries are discharged, charge them as soon as possible, as that condition makes their life shorter. WARNING! If the machine is equipped with lead (WET) batteries, battery charging produces highly explosive hydrogen gas. Charge the batteries in well-ventilated areas and away from naked ames. Do not smoke while charging the batteries. While charging the batteries always keep the hood open. WARNING! Pay careful attention when charging WET batteries as there may be battery uid leakages. The battery uid is corrosive. If it comes in contact with skin or eyes, rinse thoroughly with water and consult a physician.

1. Drive the machine on a level oor. Make sure that the machine cannot move independently.

2. Turn the ignition key (2) to “0”.

DUST FILTER CLEANING AND INTEGRITY CHECK

The dust lter must be regularly cleaned to maintain the efciency of the vacuum system. Follow the recommended lter service intervals for the longest lter life. WARNING! Wear safety glasses when cleaning the lter. Do not puncture the lter. Clean the lter in a well-ventilated area. Wear appropriate dust mask to avoid breathing in dust. NOTE Besides the standard polyester lter, paper lter is also available.

1. Drive the machine on a level oor and ensure that it cannot

2. Turn the ignition key (2) to “0”.

6. In an outdoor area, clean the dust lter by shaking it on

a level and clean surface, tapping the side (E, Fig. 12) opposite to the wire gauze (F).

7. Complete the cleaning procedure by using compressed

air (G) at maximum 6 Bar, blowing only from the side protected by the wire gauze (F). Moreover, according to the lter type, observe the following cautions:

• Polyester lter (standard): For a better cleaning, it is allowed to wash the lter with water and non-lathering detergents. This provides better quality cleaning but reduces the life of the lter, which will have to be replaced more frequently. The use of inadequate detergents can damage the lter.

• Paper lter (optional): Do not use water or detergents to clean it, otherwise it can be damaged.

8. Check the lter body for tears. Clean the gasket (H) along

its perimeter and check it for integrity. If necessary, replace the lter.

9. If necessary, clean the lter compartment rubber gasket

(D, Fig. 11) along its perimeter and check it for integrity. If necessary, replace it.

10. Assemble the components in the reverse order of
