Introduction & Machine Specifications Introduction & Machine Specifications Clarke’s newly designed BOOST 28 automatic scrubber is an efficient and superior floor cleaning machine. The BOOST 28 uses an orbital movement to scrub a path 28 inches wide. A squeegee wipes the floor while the vacuum motor removes the dirty solution from the floor - all in one pass. The BOOST 28 comes complete with four - 6 volt batteries, one battery charger, a brush or a pad, and one operator’s manual.
Procedures For Transporting How to Put the Machine Into a Van or Truck WARNING: 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. Figure #1 Machines can topple over if guided over the edges of stairs or loading docks and cause injury or damage.
Procedures For Transpoting (cont.) 10. Fasten the machine to the vehicle. Clarke 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. Figure #2 2.

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") The forward/reverse switch turns the traverse motor "on" forward and if the brush motors are 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 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 This machine 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: Correct Level Working with batteries can be dangerous. Always wear eye protection and protective clothing when working near batteries. NO SMOKING! To maintain the batteries in good condition, follow these instructions: Figure 10 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. NO SMOKING! To charge the batteries, follow this procedure: 1. Make sure the key switch is in the “OFF” position. 2.
How To Prepare the Machine For Operation How To Charge The Batteries (On-Board Charger Option) 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. NO SMOKING! To charge the batteries, follow this procedure: 1. Make sure the key switch is in the “OFF” position. 2.
How To Prepare the Machine For Operation How To Install The Brush Or Pad To install the brush or pad on the machine, follow this procedure: 1. Turn the key switch "ON". 2. Put the brush switch in the "Up" position. 3. Turn the key switch "OFF". 4. Go to the front of the machine. 5. Press on a brush or pad, under the flex plates. See figure 13. Figure 13 NOTE: When using a black pad, position pad on head.
How To Operate The Machine 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. To lower the squeegee and start the vacuum motor, move the squeegee lever to the right and down. See figure 15. 2. To raise the squeegee, lift the squeegee lever up. See figure 16.
