GENERAL SAFETY INSTRUCTIONS
Specific Cautions and Warnings are included to warn you of potential danger of machine damage or bodily harm.
WARNING!
*This machine shall be used only by properly trained and authorized persons.
* 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.
*Keep sparks, flame and smoking materials away from batteries. Explosive gases are vented during normal operation.
*Charging the batteries produces highly explosive hydrogen gas. Charge batteries only in well-ventilated areas, away from open
flame. Do not smoke while charging the batteries.
*Remove all jewelry when working near electrical components.
*Turn the key switch off (O) and disconnect the batteries before servicing electrical components.
*Never work under a machine without safety blocks or stands to support the machine.
*Do not dispense flammable cleaning agents, operate the machine on or near these agents, or operate in areas where flammable
liquids exist.
*Do not clean this machine with a pressure washer.
*Only use the brushes provided with the appliance or those specified in the instruction manual. The use of other brushes may
impair safety.
CAUTION!
* This machine is not approved for use on public paths or roads.
* This machine is not suitable for picking up hazardous dust.
* Do not use scarifier discs and grinding stones. American-Lincoln will not be held responsible for any damage to floor surfaces
caused by scarifiers or grinding stones (can also cause damage to the brush drive system).
* When operating this machine, ensure that third parties, particularly children, are not endangered.
* Before performing any service function, carefully read all instructions pertaining to that function.
* Do not leave the machine unattended without first turning the key switch off (O), removing the key and applying the parking
brake.
* Turn the key switch off (O) and remove the key, before changing the brushes, and before opening any access panels.
* Take precautions to prevent hair, jewelry, or loose clothing from becoming caught in moving parts.
* Use caution when moving this machine in below freezing temperature conditions. Any water in the solution, recovery or detergent
tanks or in the hose lines could freeze, causing damage to valves and fittings. Flush with windshield washer fluid.
* The batteries must be removed from the machine before the machine is scrapped. The disposal of the batteries should be safely
done in accordance with your local environmental regulations.
*Do not use on surfaces having a gradient exceeding that marked on the machine.
*All doors and covers are to be positioned as indicated in the instruction manual before using the machine.

MACHINE PREPARATION
WARNING!
Disconnect the traction harness before towing the machine.
7) The machine is shipped with a metal bar between the electrically actuated parking brake and the brake release lever to keep the electrically
actuated parking brake disengaged.
8) Push machine down the ramp onto a flat surface.
WARNING!
Remove the metal bar to engage the electrically actuated mechanical parking brake.
WARNING!
BEFORE towing or pushing this machine, disconnect the traction harness and reinsert the metal bar used for shipping (or similar
device) to deactivate the electromagnetic braking system. Failure to do so will result in premature wear of the friction disc or possible
destruction of the braking system.
9) Connect rear squeegee hose and install squeegee blade as shown in manual.
10) Remove battery charger from under the seat in battery compartment (if applicable).
11) Install batteries.
-Turn the key to the “O” position
-Lift the hinged seat and cover, then disconnect seat switch and remove seat plate.
-Use a battery lifting device with a 150 LB. (68KG) capacity to place the batteries battery compartment.
-Install Battery wires as shown in manual.
-Plug the polarized connector from the battery on into the 36 Volt plug provided.
-Install scrub brushes as shown in the manual.
-Lower seat and cover assembly.
12) Charge batteries as shown in the manual. Read battery manufacturer literature for battery care and maintenance.
WARNING!
Do not charge batteries on a concrete grounded surface. Hydrogen gas is formed during the charging operation and is explosive. Only
charge batteries in a well ventilated area with the lid open. Avoid any smoking, open flame, or electrical sparks.

SCRUB BRUSH SWITCH
The scrub brush switch is located on the left side of the console to right of the solution control knob as shown in figure 16. Pushing the scrub brush
switch to up position will raise the scrub deck to the top position, the scrub brushes will stop rotating, the water solenoid will de-energize and solution
flow will stop. Pushing the scrub brush switch down will lower the scrub deck to the set down pressure. The squeegee will lower and the vacuum will
activate. When the scrub brush and squeegee are on, they will be displayed as shown in figure 17. The brushes will not rotate until the foot throttle
is depressed. Releasing the foot throttle will raise the scrub deck to the top position and the brushes will stop rotating.
SCRUB PRESSURE SWITCH
The scrub pressure switch is located on the left side of the console between scrub brush switch and the squeegee/vacuum switch as shown in figure
16. Pushing the scrub pressure switch up selects the next highest scrub setting available, increasing pressure. Selected pressure is displayed as a
bar on the LCD control panel. Pressing the scrub pressure switch down selects the next lowest setting available, decreasing pressure as shown in
figure 17.
