Introduction & Machine Specifications Introduction & Machine Specifications Clarke Technology’s newly designed Encore L26 Cylindrical automatic scrubber is an efficient and superior floor cleaning machine. The Encore uses two brushes to scrub and sweep a path 26 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 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.

Machine Control Panel Circuit Breakers (See Fig 3, Items "F", "G", "H", "I" & "J") The circuit breaker reset buttons are located on the rear cover. The breakers are located as follows: Item F - Actuator Head (5 amp) Item G - Vacuum Motor (30 amp) Item H& I - Brush Motor (25 amp) Item J - Traverse Motor (25 amp) If a circuit breaker trips, determine which motor is not operating and turn the key switch "OFF". Wait five minutes and push the reset button back in. Turn the key switch "ON" and try again.
Machine Controls and Features Squeegee Lift Handle, See Figures 4 and 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. Float Shut Off, See Figure 6 The shut-off switch for the vac motor is located in the recovery tank. It automatically turns off the vac motor when the recovery tank is full.
How To Prepare the Machine For Operation How To Install The Batteries The Encore machines uses either two 12-volt batteries or four - 6 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. Tip up the recovery tank until it locks in the full open position. See figure 8A. CAUTION: Before raising the tank, be sure tank is empty.
How To Prepare the Machine For Operation Battery Maintenance The electrical power to operate the machine comes from the storage batteries. Storage batteries need preventative maintenance. WARNING: Working with batteries can be dangerous. Always wear eye protection and protective clothing when working near batteries. NO SMOKING! Correct Level To maintain the batteries in good condition, follow these instructions: 1. Keep the electrolyte at the correct level.
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 4. Disconnect the battery pack connector from the control housing connector. See figure 14A. 5. Connect the DC connector on the charger to the battery pack connector. See figure 14B. 6. Connect the charger to a properly grounded single phase (3-wire) wall receptacle having the input voltage, frequency, and ampere capacity specified on the nameplate of the charger. For more information on the use of the charger, read the instructions supplied with the charger.
How To Operate The Machine DANGER: Operating a machine that is not completely or fully assembled could result in injury or property damage. Do not operate this machine unless it is completely assembled. Inspect the machine carefully before operation. How To Operate The Squeegee The squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor. Use your hand to lower or raise the squeegee handle. To operate the squeegee, follow this procedure: 1.
How To Operate The Machine Operating The Machine NOTE: Put the machine in the lowest traverse speed setting. Use the machine in an area that has no furniture or objects until you can do the following: 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 20B 2.
How To Operate The Machine (cont) WARNING: This machine is capable of maximum head pressure with worn brushes. With this feature, there is the possibility of exceeding the recommended brush pressure on new brushes. This will either create reoccurring circuit breaker tripping or the possibility of lost traction and control. The brush switch should be activated to accomplish only enough brush pressure for the job. This will allow longer battery life and cleaning time.
Maintenance WARNING: Maintenance and repairs must be done by authorized personnel only. WARNING: Always empty the solution tank and recovery tank before doing any maintenance. WARNING: Keep all fasteners tight. These Maintenance Procedures Must Be Done Every Day Keep the machine clean, it will need fewer repairs and have longer life. Figure 22 Do These Procedures When You Begin Your Work Period 1. Turn off key switch. A 2. Disconnect AC power from battery charger (follow charger instructions). 2.
Maintenance Do These Procedures When You End Your Work 1. Drain the solution tank (Figure 25) and the recovery tank (Figure 26). To drain the tanks , follow this procedure: a. Turn the key switch “OFF”. b. Remove the drain hose from the back of the machine. Figure 25 c. Put the end of the hose over a drain or bucket. d. Recovery Tank: 1.) Turn the valve handle to the left. Pull the handle out to open the drain (Figure 27).
Maintenance 8. Check the batteries and if necessary add distlled water after charging. The correct level is within 1/4 inch (1/2 cm) of the bottom of the tube in each cell. CAUTION: Tap water may contain contaminants that will damage batteries. Batteries must be refilled with DISTILLED WATER ONLY. WARNING: Lead acid batteries generate gases which can cause an explosion. NO SMOKING. Always wear eye protection and protective clothing when working near batteries. 9.
Maintenance WARNING: Do not operate or perform maintenance on the machine while the recovery tank is in the intermediate position. The tank can be accidentally bumped and it may slam shut. 2. Disconnect the batteries. Use a cloth and a solution of ammonia or bicarbonate of soda to wipe the top of the batteries. Clean the battery terminals. Reconnect the batteries. Figure 32 3. Check the hoses for leaks, obstructions and other damage. 4. Use a grease gun to lubricate the dual casters. See figure 32. A 5.
Maintenance cont. How To Adjust The Squeegee The following adjustments are set at the factory, however they may require slight adjustment. Adjusting Squeegee Tilt: The tilt of the squeegee causes the rear blade to raise up in the center or on the ends, depending on which direction the tilt is changed. For tilt adjustment, refer to figure 35. Loosen left and right screw "X". In order to bring the blades down in the center, tip "Y" down. To bring both ends down, tip "Y" up.
Maintenance cont. 6. Locate the four mounting studs on the brush head bracket. See figure 37. The top two mounting nuts can be accessed through the top of the solution tank. The lower two can be accessed through the front. Loosen the four mounting nuts 2 to 3 turns counterclockwise. NOTE: Do not remove mounting nuts. 7. The brush head assembly can slide to the right side by one inch or placed back into the center. Slide the brush head assembly all the way to the ends of the slots for the desired position.
