Daily Maintenance

Battery Charging
 The master power switch and all other switches
(except the EMERGENCY STOP) must be turned
OFF.
 You must recharge the batteries when indicated by
the battery meter, and after every use. Read the
battery meter while the machine is in use.
*350 AH batteries normally require 14 ½ -16
to fully charge.
 NEVER let the batteries sit overnight after the
machine has been run for more than 1 hour since last
recharge.
 ALWAYS lift open the recovery tank to provide
ventilation during charging.
 See Battery Charger section.
Battery Electrolyte (Liquid) Level (Flooded only)
Inspect the electrolyte level of at least one cell in each
battery before charging. The liquid must be visible
above the internal plates. Do not charge the batteries if
the liquid is below the plates.
 Add only distilled water to the cell of a battery to
adjust the liquid level. Do not use well or tap water.
Before charging, add only enough water to cover the
top of the internal plates. After charging, add only
enough water to bring the level to the bottom of the fill
tube.
 Do not overfill the battery liquid level, this will cause
electrolyte (acid) spill. Spilled electrolyte (acid) can
cause machine damage and personal injury. Clean
up and dispose of all spills immediately.
 See the battery-warning sheet (page 3) for more
details.
 If machine is equipped with battery Auto-Fill system,
fill batteries prior to charging.

Solution and Recovery Tanks
 The recovery tank is emptied through a large rubber
hose at the front of the machine. Remove the plug
and drain the liquids according to your local and
federal regulations.
 Every time you empty the recovery tank, we
recommend that you add at least 4 to 6 ounces
[120mL to 175mL] of defoamer chemical into the
recovery tank before resuming work. Vacuum the
defoamer into the empty recovery tank through the
squeegee vacuum hose.
 At the end of the day empty all liquids from both
solution and recovery tanks. Rinse both tanks with
clean water to prevent chemical residue build-up,
allow to air - dry to prevent odors.
 Remove any residue from screen and float ball to
ensure proper operation. Replace float assembly in
recovery tank.
 Check clear lid for airtight seal.
 Check the drain hose for damage.
