MACHINE PREPARATION
BATTERIES
1.Install batteries and connect battery cables as shown.
WARNING: Provide proper ventilation, leave door open when charging batteries.
2.Charge the batteries before using the machine. (See Battery Charging Pro- cedure)
BRUSH/DRIVE PAD ASSEMBLY
1.Raise scrub deck assembly by raising control lever to store position.
2.Reach under scrub deck and rotate drive plate until a lug hole is visible through scrub deck sight hole.
3.Positlon brush/pad driver under plate and lift up to enga e brush lugs in plate. A quick countercyockwise motion will lock brush/pad driver in position.
4.Lower scrub deck by pulling control lever rearward. Adjust splash skirt to floor.
CLEANING SOLUTlON
1.Fill machine with hot water and add cleaning chemical at the proportion noted on the container.
CAUTION: Always use a low sudslng cleaning chemical desi ned for use In automatic hard surface ?loor scrubbers.
CAUTION: To avoid possible dis- tortion of polyethylene solution/ recovery tanks. DO NOT USE WATER TEMPERATURE THAT EXCEEDS 150’F (65°C).
CHEMICALS
The internal parts of the pump used in the scrubber (on models equipped with auxiliarv pumo) are suitable for use with most cleaning chemicals. But it is sus- ceptible to chemical attach from some cleaning substances, such as hydro- carbon solvents and chlorinated bleaches. These noncompatible materials are not of the type normally used for cleaning.

OPERATING THE MACHINE
1.Adjust the operator control handle to a comfortable position.
2.Switch on main power switch.
3.Release solution. Pull solution control lever rearward. NOTE The amount of solution can be regulated during oper- ation depending on the type of floor and the traverse speed of the machine.
4.Switch on brush drive motor.
5.Switch on vacuum motor.
6.Lower scrub deck. Pull deck lift lever rearward.
CAUTION: DO not leave brush running on floor while machine is stationary.
7.Lower squeegee. Pull squeegee lift lever rearward. NOTE Use adjusting knob to change pressure on squeegee.
8.Push machine forward to begin clean- ing. Forward motion is assisted by the scrubbing action of the brushlpad driver.
OPERATING MACHINE WITH ACCESSORY TOOL
The HFT floor tool for wet
used on modelswith the auxiliary pump kit o p t i o n T P eEd Factory installed option only.)
1.Remove vac hose from squeegee and connect to accessory vac hose, using metal hose coupler.
2.Connect solution hose from accessory tool to solution outlet nipple located at lower right hand corner of rear panel.
3.Check solution tank for cleaning solu- tion and make sure dome is in place.
4.Switch on main power switch.
5.Switch on auxiliary pump and vacuum switches.

REGULAR MAINTENANCE
BEFORESTARTING WORK PERIOD
1.Disconnect battery charger. NOTE Dis- connect the “AC” power cord from the wall receptacle before removing the “DC” charger plug from machine.
2.Check water level in batteries. Add distilled water as needed.
3.Attach brush or drive pad to drive plate.
4.Check vac hose connection at squeegee shoe.
5.Check squeegee blades for wear.
6.Fill machine with hot water and add cleaning chemical at the proportions noted on the container. NOTE Use a low sudsing cleaner designed for use in automatic hard surface floor scrubbers.
