Introduction & Machine Specifications Introduction & Machine Specifications Clarke Technology’s newly designed Encore S20 and L20 automatic scrubbers are efficient and superior floor cleaning machines. The Encore uses one brush to scrub a path 20 inches wide. A squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor - all in one pass.
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.
Procedures For Transporting (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 possiblity of the machine toppling over. 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 long and a minimum of 32" wide, and strong enough to support the machine.
Machine Control Panel Key Switch (See Figure 3, Item "A") The key switch turns "ON" the power to the control panel. "O" is "OFF" and "I" is "ON". Forward Reverse Switch (See Figure 3, Item "B") On Traverse Model Only The forward/reverse switch turns the traverse motor "on" forward and if the brush motor is in the down position, activates the brush motor/solution control module. There is a two second delay for the pad motor to stop after releasing the switch. Either the right or the left switch can be used.
Machine Controls and Features Squeegee Lift Handle, See Figures 5 The squeegee lift handle is located below the control handles in the center. It is used to raise or lower the squeegee. The vac motor is turned on when the handle is lowered to either the first or last position. NOTE: Squeegee must be raised to at least the first position when the machine is backed up. Float Shut Off, See Figure 6 The shut-off switch for the vac motor is located in the recovery tank.
How To Prepare the Machine For Operation How To Install The Batteries The Encore machines uses two 12-volt batteries. The batteries are located in the battery compartment under the recovery tank. To install the batteries, follow this procedure: 1. Turn machine off. Set brake (if equipped). 2. Make sure recovery tank is empty. 3. Open recovery tank and secure with latch. 4. Place the batteries in the tray as shown in figure 8. WARNING: Lifting batteries without help could result in an injury.
How To Prepare the Machine For Operation NOTE: Check the level of electrolyte prior to charging the batteries. Be sure the plates in each cell are covered with electrolyte. Do not top off the cells prior to charging the battery. Electrolyte expands during charging. As a result, the electrolyte could overflow from the cells. Always top off the cells with distilled water after charging. CAUTION: Irreversible damage will occur to the batteries if the electrolyte level does not cover the plates.
How To Prepare the Machine For Operation How To Charge The Batteries WARNING: Charging the batteries in an area without adequate ventilation could result in an explosion. To prevent an explosion, charge the batteries only in an area with good ventilation. WARNING: Lead acid batteries generate gases which could explode. Keep sparks and flames away from batteries.
How To Prepare the Machine For Operation How To Install The Brush Or Pad Driver To install the brush or pad driver on the machine, follow this procedure: 1. Turn the key switch "OFF". 2. Put the brush switch in the "UP" position. 3. Go to the front of the machine. 4. Open the brush motor cover and remove the brush housing. See figures 15a and 15b. 5. Put a brush or pad driver under the brush housing. See figure 15c. Figure 15a 6. Align the lugs on the motor with the slots in the brush gimbal. 7.
How To Operate The Machine How To Operate The Squeegee The squeegee wipes the floor while the vacuum motor removes the dirty solution form the floor. Use your right hand to lower or raise the squeegee handle. To operate the squeegee, follow this procedure: 1. To lower the squeegee and start the vac motor, move the squeegee lever to the right and down. See figure 16. 2. To raise the squeegee, lift the squeegee lever up. See figure 17.
How To Operate The Machine A B Operating The Machine NOTE: Put the machine in the lowest traverse speed setting. Use the machine in an area that has no furniture and objects until you can do the following: C A D 1. Move the machine in a straight direction, forward and backward. 2. Stop the machine safely. 3. Turn the machine both left and right and return to a straight direction. To move the machine, follow this procedure: 1. Release the parking brake (if equipped with machine). Figure 18 2.
How To Operate The Machine (cont) How To Clean A Floor WARNING: Water solutions or cleaning materials used with this type of machine can leave wet areas on the floor surfaces. These areas can cause a dangerous condition for the operator or other persons. Always put CAUTION signs near the area you are cleaning. To clean a floor follow this procedure: 1. Set the parking brake (if equipped with machine.) 2. Put the water and a cleaning chemical in the clean solution tank. 3.

HOW TO CORRECT PROBLEMS IN THE MACHINE PROBLEM There is no solution flow. The solution flow does not stop. The machine does not remove all the water from the floor. The batteries do not give the normal running time. Page -18- CAUSE ACTION The solution valve is closed. Open the solution valve. There is an obstruction in the solution hose or filter. Remove the obstruction from the hose and the filter. The solution valve or electric wiring is damaged.
PROBLEM The cleaning is not even. CAUSE ACTION The scrub brush or pad is worn. Replace the scrub brush or pad. There is damage to the brush assembly, caster or the solution valve. Have an authorized service person make the needed repairs. The brush motor is not running Check for tripped breaker. Reset. Check for loose connections. The solution level is low. Fill the solution tank. NOTE: If the problem continues consult an authorized service person. The machine does not run.
