BATTERIES WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm, and during charging, strong inorganic acid mists containing sulfuric acid are involved, a chemical known to the State of California to cause cancer. Wash hands after handling. For more information go to www.P65Warnings.ca.gov.
SERVICING LEAD ACID BATTERIES WITH HYDROLINK WATERING ® SYSTEM Position the container of distilled water below the level of the top of the batteries to prevent siphoning. Place the end of the watering system hose in the distilled water and squeeze the bulb to fill the system. Remove the dust cover from the Hydrolink snake connected to the batteries.
CLEANING THE BATTERYSHIELD SENSOR LIGHT PIPE ® CAUTION: Always wear protective clothing, gloves and goggles when handling and charging batteries. NOTE: All repairs must be performed by a qualified service technician using approved replacement parts. Locate and remove the battery cap with the BatteryShield sensor module.
CHARGING WARNING: Batteries emit hydrogen and oxygen gas. • Keep sparks and open flame away. • Do not smoke near the machine. • Charge batteries in a well-ventilated area with the battery compartment open. WARNING: Do not wear jewelry when working near moving or electrical components. WARNING: Do not plug in the charger cable if wall cord or battery harness is damaged.
OFF-BOARD CHARGING WARNING: This product can expose you to chemicals including lead and lead compounds which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www. P65Warnings.ca.gov. WARNING: Batteries emit hydrogen and oxygen gas.

TURNING THE UNIT ON/OFF The key switch is located on the control panel. When the machine is not in use, remove the key and store it in a secure location. CIRCUIT BREAKERS The circuit breakers on the control panel protect the components from high amp-draw. In particular, the scrub head circuit will draw too many amps when overloaded by improper application setup.
Telemetry-equipped machines have a keypad mounted on the upper right side of the control panel. After turning on the key switch, enter the operator code. Failure to enter a valid operator code will prevent the machine from functioning. Operator codes are generated and administered by your Pacific Distributor or your company’s management.
SOLUTION FLOW Solution flow is controlled by the Solution Flow Control located on the Control Panel. When the Scrub Head in lowered, solution is delivered at a rate of 0 - 0.5 gpm (0 - 1.9 lpm) based upon the Solution Flow setting and the speed of the machine (flow rate increases or decreases with machine speed to prevent over/under distribution).
ORBITAL SCRUB HEAD & CHEMICAL-FREE FINISH REMOVAL NOTE: Do not operate the Orbital Scrub Head without a pad installed. Operating the head without a pad will damage the Mighty-Lok face. ® NOTE: Use of caustic, high ph, or degreasing chemicals can decrease the service life of components, including the orbital head bearing.
DISK SCRUB HEAD DISK INSTALLATION NOTE: Do not operate the Disk Scrub Head without a pad installed on the pad driver. Operating the head without a pad will damage the floor. Turn the key switch on and rotate the speed control knob to the full slow position. Place the pad drivers or brushes on the floor in front of the scrub head.
RECOVERY SYSTEM RECOVERY TANK To drain and rinse the recovery tank: Remove the Recovery Drain Hose from the holder and lower the end into the drain location. Remove the press-fit cap from the Recovery Drain Hose, squeezing the restriction collar to control the flow. As the tank drains, lift the Recovery Tank to the open position.
Page 22
SQUEEGEE SYSTEM Squeegee Blades and system should be inspected and maintained regularly to achieve peak machine performance. REMOVAL & INSTALLATION Install: Align the slots in the squeegee assembly with the easy-grip knobs, attach the vacuum hose, and tighten the knobs. Remove: Loosen the easy-grip knobs, remove the vacuum hose, and remove the assembly.
Page 23
INSPECTION & CLEANING Inspect both squeegee blades. Blades edges are considered worn if the edge is not clearly defined or if the edge is worn halfway through the thickness of the blade. Blades can be flipped and rotated to use all four edges. Thoroughly clean the blades, frame, and neck of any debris.
