FORM NO. 56041583 - Adgressor ™ / BR 850S, 850CS, 950S, 950CS, 1050S, 1050CS - 15ENGLISH / 15OPERATING THE MACHINEWARNING!Be sure you understand the operator controls and their functions.While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills. Clean onlywhile ascending (driving up) the ramp.To Scrub...Follow the instructions in preparing the machine for use section of this manual.1 While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (25) and (5).2 Turn the Master Key Switch (J) ON (I). This will display the control panel indicator lights, reference the Battery Condition Indicator (K) and Hour Meter(G).3 Release the Parking Brake (6). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (8) to goforward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.4 Adjust the Solution Flow Control Valve Lever (7) to about 1/4 to 1/3 open position. Note the adjustment can be changed to allow variable solution flowfor different types of floors to be scrubbed. Example: A rough or absorbent floor surface, such as unfinished concrete, will require more solution than asmooth finished floor.NOTE: For a consistent reduced flow of solution; open the Solution Flow Control Valve Lever (7) all the way and then turn ON the Smart Solutions™ /ECO Solution™ valve.5 Press the Solution Switch (R) and hold for 5 seconds. This is done to pre-wet the floor. Note: This will help prevent scarring of the floor surface whenstarting to scrub with dry brushes.6 Press the Scrub Pressure Decrease Switch (D) or the Scrub Pressure Increase Switch (F) to activate the scrub system. Note: refer to the FunctionalDescription of Control Switches section for a more detailed explanation of these and other control panel functions.7 When the Scrub Pressure Decrease Switch (D) or the Scrub Pressure Increase Switch (F) are selected, the brushes and squeegee are automaticallylowered to the floor. The machine’s scrub brush rotation, solution system flow and vacuum starts when the Drive Pedal (8) is activated. Note: Whenoperating the machine in reverse, only the brushes will rotate, the solution is automatically shut off to conserve the solution usage.8 Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Adjustwhen necessary the machine speed and solution flow according to the condition of the floor.CAUTION!To avoid damaging the floor, keep the machine moving while the brushes are turning.9 When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, youmay be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.10 For extremely dirty floors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation isthe same as a one-pass scrubbing except on the first pass the squeegee is in the up position (press the Vacuum Switch (O) to raise the squeegee).This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the same area, with the squeegee lowered to pickup the accumulated solution.11 The recovery tank has an automatic float shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the floatshut-off is activated, the control system will shut down the scrub, vacuum and solution systems. The Scrub Pressure / Hourmeter Display (G) will display“FULL”. To clear the display, press the Scrub OFF Switch (B), Scrub Pressure Decrease Switch (D), Scrub Pressure Increase Switch (F) or the VacuumSwitch (O). When the float closes, the recovery tank must be emptied. The machine will not pick up water with the float closed. NOTE: If the controlrepeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a qualified service technician refer to theservice manual to perform this function.12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (B) once. This will automatically stop the scrubbrushes and solution flow and the scrub deck will raise UP. NOTE: the vacuum/squeegee system will not be turned off when the switch is only pressedonce, this is to allow any remaining water to be picked up without turning the vacuum back on. Press the switch a second time and the squeegee willraise and the vacuum will stop after a 10 second delay.13 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (21) from its rearstorage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Refillthe solution tank and continue scrubbing.
