MACHINE MAINTENANCE

Daily Maintenance
• Recharge the batteries when indicated by the
Battery Discharge Indicator.
• Empty and rinse clean the recovery tank.
• Remove and rinse clean the squeegee assembly.
• Remove and rinse clean the pad driver and / or
brush.
• Inspect the machine components for wear or
damage. Call an authorized service center for
repairs.
• Wipe machine down; NEVER spray this machine
with water or any liquids.
Weekly Maintenance (Every 25 Hours)
• Verify that all daily maintenance has been
performed.
• Inspect the battery liquid level; using only water,
adjust to the proper level as needed.
• Refill the batteries using the Auto Fill System
provided with the batteries.
• Check all battery terminal and cable connections.
Tighten as deemed necessary.
• Clean any corrosion from the battery terminals and
cables.
• Check the solution flow to the pad driver and / or
brush. Flush clean the solution tank and hose with
a mixture of 8 oz. (250ml.) of white vinegar to 1
gallon (4 liter) of warm water.
• Inspect filters.
Monthly Maintenance (Every 100 Hours)
• Verify that all daily and weekly maintenance has
been performed.
• Clean filters by rinsing with cool, clear water. Dry
Completely.
After every 750 Hours of Operation:
• Inspect the drive motor carbon brushes for wear.
Replace the brushes when they are 3/8 in. (9mm.)
in length.
• Inspect the brush drive motor carbon brushes for
wear. Replace the brushes when they are 1/2 in.
(13mm.) in length.
• Inspect the vacuum motor carbon brushes for
wear. Replace the brushes when they are 7/16 in.
(11mm.) in length.

Battery Charger

Operating instructions

1. Connect charger power cord to a properly grounded
outlet. When using an extension cord, avoid
excessive voltage drop and extended charge times
by using a grounded 3-wire 12 AWG cord for 50'
lengths or shorter and 10AWG for greater than 50'
lengths.
2. If a minimum battery voltage is not detected, a
trickle current will be applied until a minimum
voltage is reached.
3. Once a minimum battery voltage is detected, the
charger will enter the bulk charging constant-current
stage. The current bar graph will indicate the
current to the battery as the charger moves through
its charge profile. The length of charge time will
vary by how large and how depleted the battery
pack is.
4. When the yellow 80% LED is lit, the charger has
completed the bulk stage of the charge and the
battery is at approximately 80% of charge. The
charging could be terminated at this point if the
machine requires immediate usage, however, it is
highly recommended to wait until the green 100%
charge LED illuminates to ensure maximum battery
capacity and battery life.
5. When the green 100% LED is continuously on, the
batteries are completely charged. The charger may
now be unplugged from AC power (always pull on
plug and not cord to reduce risk of damage to the
cord). If left plugged in, the charger will
automatically restart a complete charge cycle if the
battery pack voltage drops on average below 2.1
volts-per-cell or 30 days has elapsed.
6. If a fault occurred anytime during charging, the red
FAULT LED will flash with a code corresponding to
the error. To indicate which error, the FAULT LED
will flash a number of times at a rate of two times
per second, pause 0.5 seconds, then repeat.
[1 FLASH] Battery Voltage High: auto-recover
[2 FLASH] Battery Voltage Low: auto-recover
[3 FLASH] Charge Timeout: the charge did not
complete in the allowed time. This may indicate a
problem with the battery pack (voltage not attaining
the required level), or that the charger output was
reduced due to high ambient temperatures.
[4 FLASH] Check Battery: the battery pack could
not be trickle charged up to the minimum level
required for the charge to be started. This may
indicate that one or more cells in the battery pack
are shorted or damaged.
[5 FLASH] Over-Temperature: auto-recover.
Charger has shutdown due to high internal
temperature. Charger will restart and charge to
completion if temperature comes within accepted
limits, but the fault LED indication will remain until
the charger has been reset (AC removed).
[6 FLASH] QuiQ Fault: an internal fault has been
detected. If Fault 6 is again displayed after
interrupting AC power for at least 10 seconds, the
charger must be taken to a qualified service depot.
