INTRODUCTION

The BSW 28 Clarke’s sweeper has been designed and built to clean (by sweeping and vacuuming) smooth and solid floors, in civil and industrial environments and to collect dust and light debris under safe operation conditions by a qualified operator. BSW 28 is equipped with:
– one side broom, which removes dust and debris on the machine front right end side (along footpaths, walls, etc.) and it conveys them toward the main broom.
– one main broom, which removes and collects dust and debris that are then vacuumed into the hopper; the cleaning width is 28 in (720 mm).

HOW TO KEEP THIS MANUAL
The Operator’s Manual must be kept near the machine, inside an adequate case, away from liquids and other substances that can cause damage to it.

IDENTIFICATION DATA
The machine model and serial number are marked on the label and can be read from the outside (AC, Fig. 2).
The machine model year is written in the Declaration of Conformity and it is also indicated by the first two figures of the machine serial number.
This information is useful when requiring machine spare parts. Use the following table to write down the machine identification data for any further reference.

– DANGER
– WARNING
– CAUTION
– CONSULTATION

While reading this Manual, the operator must pay particular attention to these symbols.
Do not cover these labels for any reason and immediately replace them if damaged.

BATTERY CHECK ON A NEW MACHINE
The machine is supplied with a standard 12 V, 86 AH@20,
GEL battery (which does not require maintenance).

BEFORE MACHINE START-UP

1. Make sure that there are no open doors/hoods and that the machine is in normal operating conditions.
2. If the machine has not been used after being transported, check that all the blocks used for the transportation have been removed.
3. Check that side and main broom are installed, otherwise install them (see the procedure in Maintenance chapter).

MACHINE START AND STOP
Machine start

Adjust the handlebar (A, Fig. 3) to reach a comfortable position, by loosening the knobs (B). When the adjustment is completed, tighten the knobs.
2. To use the main broom (C, Fig. 3) only, turn the main switch (D) to “I”.
To use the side broom (E) too, turn the main switch (D) to “II”.
Check that the green warning light (F) turns on (charged battery).
If the yellow (G) or red warning light (H) turns on, turn the main switch (D) back to “0” and charge the battery (see the procedure in Maintenance chapter).
3. Lower the main broom (E, Fig. 3) by disengaging the lever (I) and by pushing it forward.

NOTE:
The side broom (E) can be lifted and lowered even if it is turned on.

4. Start sweeping by grasping the handlebar (A) and pulling the drive control lever (J) gradually. Machine stop
1. Release the drive control lever (J) to stop the drive system.
2. Turn off the vacuum system and the brooms, by turning the main switch (D) to “0”.
3. Lift the side broom (E) by pulling the lever (J) backwards and by engaging it to the fastener.

MACHINE OPERATION

1. Avoid stopping for a long time with the machine in the same position and the brooms rotating: this could create unwanted marks on the floor.
2. For machine proper operation, the dust filter must be as clean as possible. Therefore the filter shaker must be used at regular intervals (every 10 minutes, but this interval may vary according to the floor conditions), according to the following procedure.
   – Stop the machine and turn the main switch (A, Fig. 4) to “0”.
   – To shake the filter, move the filter shaker knob (B) to the right and then to the left several times.
   – Turn the main switch (A) to “I” and start sweeping again.

NOTE:
When the dust filter is clogged, the machine cannot collect dust and debris anymore.

CAUTION:
Do not work on wet floors to prevent the dust filter from being damaged.

3. The hopper (C, Fig. 4) 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.

HOPPER EMPTYING
1. Stop the machine and turn the main switch (A, Fig. 4) to “0”.
2. Remove the hopper (C) by using the handles (D) and (E), then empty it at the waste collection centre.
3. Install the hopper (C).
4. The machine is ready to start working again.

NOTE:
The machine cannot operate when the hopper is removed.

AFTER MACHINE USE

After working, before leaving the machine:

1. Turn the main switch (A, Fig. 4) to “0”.
2. Turn on the filter shaker with the knob (B).
3. Empty the hopper (C) (see the procedure in the previous paragraph).
4. Lift the side broom (F, Fig. 4) by pulling the lever (G) backwards and by engaging it to the fastener.
5. Make sure that the machine cannot move independently.
6. Charge the battery (see the procedure in Maintenance chapter).

MACHINE STORAGE

If the machine is not going to be used for more than 30 days, proceed as follows:

1. Perform the daily maintenance procedures (see the previous paragraph).
2. Check that the machine storage area is dry and clean.
3. Slightly lift the machine so that the skirts, the main broom and the wheels do not touch the ground.

FIRST PERIOD OF USE

After the first 8 hours, check the machine fastening and connecting parts for proper tightening, and check the visible parts for integrity and leakage.

MAINTENANCE

WARNING: All maintenance procedures must be performed by qualified personnel, or by an authorized Service Center.
WARNING: Maintenance procedures must be performed:
– With the machine switched off
– With the battery disconnected (if required)
– With the battery charger cable disconnected from the electrical mains
Moreover, read carefully the instructions in the Operator’s Safety Instructions chapter before performing any maintenance procedure.

The lifespan of the machine and its maximum operating safety are ensured by correct and regular maintenance.
The following table provides the scheduled maintenance. The intervals shown may vary according to particular working conditions, which are to be defined by the person in charge of the maintenance.
This Manual describes only the easiest and most common maintenance procedures.

SCHEDULED MAINTENANCE TABLE

BATTERY CHARGER CABLE INTEGRITY CHECK
Carefully check the battery charger cable (A, Fig. 5) and the relevant plug (B) for cuts, wear and other damages.

3. On both sides of the machine, loosen the knob (A, Fig. 11).

4. Grasp the support (B, Fig. 11) on the points (C) and move it outward, then lift it or lower it to change the main broom height; for height variation, refer to the indicator (D). Then tighten the knob (A) on both sides of the machine.

5. Perform step 1 again to check proper adjustment of main broom height.

6. When the broom is too worn to be adjusted, replace it as shown in the next paragraph.

CAUTION:
An excessive print (larger than 2 in (5 cm)) of the main broom can lead to machine malfunction and overheating of its moving and electrical parts, thus reducing machine life.

Pay careful attention when performing the above-mentioned checks, and always use the machine according to the instructions.

7. Remove the filter (A, Fig. 19) from the frame (B) by disengaging the rubber bands (C).

8. In an appropriate outdoor area, clean the filter by shaking it on a level and clean surface, tapping the side (D, Fig. 19) opposite to the gasket (E). Complete the cleaning procedure by using compressed
   air (F) at maximum 90 PSI (6 Bars), blowing only from the side of the gasket (E), at a minimum distance of 12 in (30 cm).
   Filters can also be washed with water and a mild detergent. Check the filter body for tears. If necessary, replace it.

SKIRT HEIGHT AND OPERATION CHECK

1. Drive the machine on a smooth and level ground that is suitable for checking the skirt height.

2. Turn the main switch (A, Fig. 21) to “0”.

3. Check that the height from the ground of the side skirts (A and B, Fig. 20) is 0 – 0.08 in (0 – 2 mm).
   Check the skirts for integrity, cuts or tears, which can reduce the machine vacuum capabilities.
   If necessary replace the side skirts (see the procedure in the Service Manual).

4. Check that the front and rear skirts (C and D, Fig. 20) slightly rub on the ground. Check the skirts for integrity, cuts or tears, which can reduce the machine vacuum capabilities. Note that the front skirt has typical vertical cuts (E). If necessary replace the front and rear skirts (see the procedure in the Service Manual).
