HOW TO ASSEMBLE THE PS-27

1. Remove the four (4) handle mounting screws from the handle brackets on the machine.

2. Slide the handle over the angle brackets. Line up the holes in the handle with the holes in the handle brackets and reinstall
the four (4) screws.

3. Pull the handle on top of the hopper upward and lift the hopper off of the machine.

4. Lower the side broom into the side broom bracket so that the holes in the bracket are lined up with the hole in the arm.

5. Slide the pin (from the hardware package) through the holes in the bracket and into the arm. Position the pin so that
it is centered on the bracket.

6. Install the black Phillips head screw on the side broom. Tighten the screw to hold the pin in place.

7. Lift the right, rear wheel off of the ground and put the belt around the pulley on the inside of the wheel. Pivot the side
broom arm all the way up.

8. Pull the belt towards the front of the machine and twist the belt ¼ turn counter-clockwise (the part of the belt from the
top of the rear wheel should move away from the machine.)

9. Lift the belt so that it is outside of the side broom arm and install it around the side broom pulley.

10. Route the belt between the two (2) white plastic pulleys.

11. Install the side broom on the side broom arm using the three (3) screws and the three (3) lockwashers.

12. Lower the side broom arm and position the belt so that it runs through the side broom arm.

13. Screw the side broom adjustment knob into the side broom arm. Adjust the knob so that about 1/3 of the side broom
bristles are touching the floor.

14. Loosen the two (2) screws that hold the side broom bracket against the chassis. Make sure that the height adjustment
screw is between the edges of the stop bracket on the frame.

15. Pull the side broom forward as far as the belt will allow, and tighten the screws.

HOW TO OPERATE THE PS-27 SWEEPER

1. Adjust the height of the main sweeping broom so that the bristles just touch the floor. NOTE: Sweeping performance
will be poor and the machine will be hard to push if the main broom is set too low.

2. Lower the side broom when sweeping along curbs or walls. NOTE: Adjust the side broom height so that 1/3 of the bristles
are touching the floor.

3. Push the machine forward to enable the main broom to kick dirt and debris into the dirt hopper. NOTE: The machine
will not sweep when it is pulled backward.

4. Lift the hopper off of the machine and empty it after each use, or whenever debris is left behind the machine.

CLARKE TECHNOLOGY Operator's Manual PS-27 Page 5

MAINTENANCE

Monthly:

1. Tip the machine on its side and remove any string that is wrapped around the main sweeping broom.

2. Lubricate the front caster wheel with light machine oil.

3. Inspect the rubber skirt on the hopper. Replace the skirt if it is torn.

Every Six Months:

1. Inspect the rubber skirts on each side and behind the sweeping broom. Replace the skirt if it is torn.

2. Tip the machine on its side and inspect the main broom for wear. Replace the broom when the bristles are worn to a length
of 1½ inch (38MM).

Renewal of the Broom Assemblies:

1. The broom roller consists of a broom shaft with three broom supports, one lock washer with a hollow screw and ten (10) broom
assemblies as follows:

(5) broom assemblies with bristles of 0.006 in. (0.15MM).
(5) broom assemblies with bristles of 0.01 in. (0.25MM).

Broom Assembly Replacement:

1. Unscrew the cap screw (Allen Key, 0.2 in. - 5MM).

2. Turn the lock washer slightly until the notch at the end of the broom assemblies are placed next to each other.

3. Pull the broom assembly to the left to unlock it from the broom supports on the broom shaft.

4. Turn the lock washer and remove the broom assembly.

5. Insert the new broom assemblies onto the shaft so that the 0.006 in. (0.15MM) and 0.01 in (0.25MM) bristles are alternated.
