Introduction & Machine Specifications

Clarke Technology’s newly designed Encore S2426 and L2426 automatic scrubbers are efficient and superior floor cleaning machines. The Encore uses two brushes to scrub a path 24 or 26 inches wide. A squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor - all in one pass.

The Encore S2426 comes complete with either four - 6 volt batteries or two - 12 volt batteries, one battery charger, either two brushes or two pad drivers, and one operator’s manual.

The Encore L2426 comes complete with four - 6 volt batteries, one battery charger, either two brushes or two pad drivers, and one operator’s manual.

Procedures For Transporting

How to Put the Machine Into a Van or Truck

WARNING: This machine is heavy. Get

assistance before attempting to transport or move it. Use two able persons to move the machine on a ramp or incline. Always move slowly. Do not turn the machine on a ramp. Do not stop and leave the machine on a ramp or incline. The loading ramp must be a minimum of 32" wide.

WARNING: Machines can topple over if

guided over the edges of stairs or loading docks and cause injury or damage. Stop and leave this machine only on a level surface. When you stop the machine, put all switches into their "OFF" position.

1. Make sure the loading ramp is at least eight

(8) feet (2.5m) long and a minimum of 32" (0.8m) wide, and strong enough to support the machine.

2. Make sure the ramp is clean and dry.

3. Put the ramp in position.

4. Remove squeegee assembly, brush housing and brush or pad driver before loading. ALTO recommends that both the solution tank and recovery tank are empty before loading.

5. Turn key switch "ON" (on L2426 model only).

Figure #1

6. Align the machine on a level surface five (5) feet (2 m) in front of the ramp.

7. Put the traverse knob at full speed (on L2426 model only).

8. For the L2426 machine, push in either one of the forward/reverse switches while pushing in the white reverse switch. Back the machine up the ramp. See figure 1.

9. For the S2426 machine, push the machine backwards to the top of the ramp.

10. Turn the key switch "OFF".

Page -6- CLARKE TECHNOLOGY Operator's Manual -Encore S2426/L2426

Procedures For Transpoting (cont.)

11. Fasten the machine to the vehicle. Clarke Technology recommends a strap over the top of the machine and a strap to keep the machine from rolling forward or backwards. If this is not done, there is a possibility of the machine toppling over. Four tie down points (2 along each side of frame) are provided on machine for securing machine.

How to Remove the Machine From a Van or Truck

1. Make sure there are no obstructions in the area.

2. Make sure the unloading ramp is at least eight (8) feet (2.5m) long and a minimum of 32" (0.8m) wide, and strong enough to support the machine.

3. Make sure the ramp is clean and dry.

4. Put the ramp in position.

Figure #2

5. Unfasten the machine.

WARNING: The machine is heavy.

Make sure you use two able persons to assist in moving the machine down the ramp.

6. On S2426 model, get two people to pull machine off ramp. It is recommended that the "S" model be unloaded in the forward position.

7. Turn the key switch "ON". (L2426 model only)

8. Set the traverse center knob to the slowest forward speed setting. Carefully and slowly, drive the machine to the top of the ramp and start down.

9. While pushing in the right or left forward/reverse switch the machine will go forward. See figure

10. As the machine begins to travel down the ramp, push in the forward/reverse switch to maintain a slow downward speed.

11. Replace squeegee assembly, brush housing, and brush or pad driver after machine is unloaded and ready to use.
