DISPLAY SCREENS FOR SCRUBTEC 770L, 784L, 795L Position arrow indicating current position of squeegee (up or down) 3 Indicators are on all the time showing current settings. SCREEN 1 Water “droplets” off when solution is off and they are flashing when solution is on. “Battery” blinks when low voltage occurs. Screens Available to Operator Arrows indicating vacuum status. They are flashing when vac is on and off when vac is off. SCREEN 2 Example SCREEN 3 (Diagnostic) The Diagnostic only.
EN MACHINE CONTROLS & FEATURES Squeegee Lift Handle (“S Class” models only) See Figure #3a, 3b, & 3c. The squeegee lift handle is located below the control handles on the right side. It is used to raise or lower the squeegee. The vac motor is turned on when the handle is lowered. Parking Brake (Optional)See Figure #4. The parking brake prevents movement of the machine. The brake is located on the left hand side of the transaxle motor.
HOW TO PREPARE THE MACHINE FOR OPERATION How To Install The Batteries 38722B 1. Turn key switch off. 2. Make sure both tanks are empty. 3. Disconnect the hoses from the recovery tank (upper tank) & unplug the vac motor and float switch. 4. Remove the tank support bracket. 5. Remove the recovery tank. 6. Place the batteries in the solution tank as shown in figures 6a and 6b. 38720B To Install the batteries, follow this procedure: 38720B The Scrubtec machines use six 6-volt batteries.
HOW TO PREPARE THE MACHINE FOR OPERATION Battery Maintenance The electrical power to operate the machine comes from the storage batteries. Storage batteries need preventive maintenance. WARNING! Correct fill 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: 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 Install The Brushes Or Pad Drivers To install the brushes or pad drivers 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. Unlatch right and left brush housings and remove them. See figure #9. 6. Put a brush or pad driver under the brush motor plate. See figure #10. 7.
HOW TO OPERATE THE MACHINE How to Operate the One Touch System (“L Class” models only) One touch cleaning is a feature on the new Scrubtec Walk-behind Scrubber. The factory defaults for this setting are two bars of brush pressure and four bars for solution flow and squeegee in the down position. 1. Press and release the green button for all cleaning functions to begin, see figure #11, item A. 2. The squeegee and brush head lower to the floor and the vacuum starts.
HOW TO OPERATE THE MACHINE How To Operate the Squeegee (“S Class” models only) The squeegee wipes the floor while the vacuum motor removes the dirty solution from 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 #12. 2. To raise the squeegee, lift the squeegee lever up. See figure #13.
HOW TO OPERATE THE MACHINE How To Traverse Machine NOTE: Put the machine in the slow traverse speed (see figure #17). Use the machine in an area that has no furniture and objects until you can do the following: 1. Move the machine in a straight direction, forward and backward. 2. Stop the machine safely. 3. Move the machine in a straight direction after you turn the machine. To move the machine, follow this procedure: 1. Turn the key switch “ON” position. 2.
HOW TO OPERATE THE MACHINE How to Clean a Very Dirty Floor To clean a very dirty floor, follow this procedure: 1. Apply solution to the floor. 2. Do not lower the squeegee. 3. Do not activate the vacuum motor. 4. Lower the brushes and scrub the floor. 5. Leave the solution on the floor long enough for the solution to begin cleaning the floor. 6.
MAINTENANCE Do These Procedures When You End Your Work 1. Drain the solution tank (Figure #21, item A) and the recovery tank (Figure #21, item B). To drain the tanks , follow this procedure: a. Turn the key switch “OFF”. b. Remove the drain hose from the back of the machine. c. Put the end of the hose over a drain or bucket. d. Recovery Tank: Turn the valve housing to the left (see figure #22). To open the valve completely, turn the housing fully to the left and pull the housing off of the valve.
MAINTENANCE These Maintenance Procedures Must Be Done Every Week: WARNING! Maintenance and repairs must be done by authorized personnel only. Always empty the solution tank and the recovery tank before doing any maintenance. Keep all fasteners tight. WARNING! Always wear eye protection and protective clothing when working near batteries. Do not put tools or other metal objects across the battery terminals or the tops of the batteries.
MAINTENANCE 7. Check the squeegee and the scrub brushes or the pad drivers for damage. 8. Check the squeegee and the vacuum hose for damage, leaks and obstructions. Maintenance For The Squeegee To remove the squeegee, follow this procedure: 1. Remove the squeegee assembly by loosening the two knobs that attach the squeegee to the machine. Pull the squeegee assembly off. See figure #26. 2. Inspect the squeegee blade. 3.
MAINTENANCE Adjusting Squeegee Blades When properly installed the front blade should be approximately .12 above the rear blade. See figure #29. WARNING! Maintenance and repairs must be done by authorized personnel only. WARNING! Electrical repairs must be done by authorized personnel only. 0.12" (3.0 mm) Consult your Nilfisk Alto Authorized Service Person to do the service procedures. Figure #29 Use only genuine Nilfisk Alto parts.
HOW TO CORRECT PROBLEMS IN THE MACHINE PROBLEM The machine does not remove all the water from the floor. CAUSE The squeegee is up ACTION Lower the squeegee. The vacuum tank is full. Drain the tank. The screen filter is dirty. Clean the screen filter. There is an obstruction or damage in the squeegee, squeegee hose or standpipe. The vacuum motor is not running. Remove the obstruction or repair the damage. Check for tripped breaker. Have an authorized service person make repairs. Connect the hose.
