WET SCRUBBING

WARNING!
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 only while ascending (driving up) the ramp.
1 Follow the instructions in the Preparing the Machine For Use section of this manual.
2 Turn the Master Key Switch (A, 28) ON (I). This will display the control panel indicator lights; reference the Battery / Hour Gauge on the
Display (F, 27).
3 To transport the machine to the work area, push either of the Palm Buttons (C, 23) to go forward or press the Reverse Button (D, 24) to move
the machine in reverse.
NOTE: Speed Control Knob (B, 26) is used to control the maximum speed in either forward or reverse.
4 Use Deck Lever (32) to lower deck, (machine is now ready to scrub when the machine begins to move). Use Deck Lever (32) to increase
scrub pressure by locking lever into the medium or high position on the Deck Lever Support. SEE DETAIL 1.
Use Solution Control Lever (E) to regulate the amount of solution being dispensed. Solution will only dispense while scrubbing.
EcoFlex models only: Use the Detergent Module (G, 7b) to regulate the amount of solution and detergent being dispensed.
5 Lower the squeegee with the Squeegee Raise / Lower Lever (30).Vacuum motor will turn on when squeegee is lowered and turn off when
raised.
6 When the Palm Buttons (C, 23) and Reverse Button (D, 24) are not being pressed and the machine is stationary the scrub, solution and
detergent (EcoFlex models) systems will pause. Grip the Operator Control Handle (2) and press any of the Palm Buttons (C, 23) or the
Reverse Button (D, 24) to resume scrubbing. For best results, move the machine at a slow walking speed.
CAUTION!
To avoid damaging the oor, keep the machine moving while the brushes are turning.
7 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, you may be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.
8 For extremely dirty oors, a one-pass scrubbing operation may not be satisfactory and a "double-scrub" operation may be required. This
operation is the same as a one-pass scrubbing except on the rst pass the squeegee is in the up position. This allows the cleaning solution
to remain on the oor to work longer. The nal pass is made over the same area, with the squeegee lowered to pick up the accumulated
solution.
9 The recovery tank has a shut-off oat (4) that causes a change in pitch in the vac motor. When this oat is activated, the recovery tank must
be emptied. The machine will not pick up water with the oat activated. NOTE: Empty the debris catch cage every time you drain the
recovery tank.
10 When the operator wants to stop scrubbing or the recovery tank is full;
11 Raise the deck and lift the squeegee when all the water has been picked up.
12 Drive the machine to a designated wastewater "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose
(29) from its hanger and open the cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled ow of waste
water). The Recovery Tank Drain Hose (29) can be squeezed to regulate the ow. Re ll the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (6) and the Recovery Tank Drain Hose (29) cap is properly seated or the machine will not pick-up
water correctly. When the batteries require recharging the Battery / Hour Gauge (F, 27) ashes the 2nd LED from the left as a warning that the
battery has discharged 70%. At 80% discharge, the display alternately ashes the left 2 LEDs to indicate very low capacity is remaining. At this
level the scrub systems are disabled to protect the battery. The vacuum system will continue to operate to allow recovery of any solution remaining
on oor. Transport the machine to a service area and recharge the batteries according to the instructions in the Battery section of this manual.
SERVICE NOTE: Refer to the service manual for detailed functional descriptions of all controls.
