How To Prepare the Machine For Operation
6.
Connect the charger to a properly grounded single phase
(3-wire) wall receptacle. NOTE: When the charger is
plugged into the wall receptacle, the yellow light will be
illuminated on the control panel next to the plug symbol
and the charger with begin charging (see figure 3, item A).
3-Stage Charging Sequence:
•
Bulk Stage - In the bulk stage of charging, the red light
is illuminated on the charger (See Figure 17). During
this stage the charger is supplying its full amp output to
the batteries. It will continue to charge the batteries at
this rate until the batteries reach approximately 75% of
their capacity.
•
Absorption Stage - In the absorption stage the red and
green light will be illuminated on the charger (See
Figure 17). During this stage the charger maintains
constant voltage and lets the batteries absorb the
charge at their own rate.
•
Float and Maintenance Stage - In the maintenance
stage the red light turns off and only the green light will
be illuminated on the charger (See Figure 17. During
this stage the charger applies a lower, closely regu-
lated voltage to maintain full charge and prevents
discharge. Batteries can be connected indefinitely
without harm.
7.
Unplug charger power cord from the wall outlet before
powering up control panel on machine. Store the charger
power cord in the storage compartment located under the
control handle (See Figure 16).

Unlatch and stow prop rod back in solution tank and close
recovery tank after charging has been completed.
NOTE: It is not necessary to remove the brush housing assembly
when removing or installing the brush or pad driver. For greater
access to the brush or when driving the machine up a ramp, the
brush housing assembly can be removed.
housing assembly, pull outward on the spring loaded pin on the left
side of the housing, then lift the brush housing assembly up and
outward (See Figure 18). Reinstall the brush housing assembly in
reverse order, making sure the cross bar in the brush housing is
inserted into the two slots located in the motor mount and the spring
loaded pin is locked into position (See Figure 19).
How To Install Rotary Brush or Pad Driver (if equipped)
To install the brushes or pad drivers on the machine, follow this
procedure:
1.
Turn the key switch clockwise ("L" models only). Press the
green "ON" button.
2.
Raise the brush head by pressing and holding the brush up
switch until brush head is in it's full up and rotated position
(See Figure 20).
3.
Press the red "OFF" button or turn the key switch counterclock-
wise on machines equipped with key.
4.
Put a brush or pad driver under the brush motor plate and align
the lugs on the motor with the slots on the brush gimbal.
5.
Push the brush up and rotate counter direction to scrub
rotation, until lugs lock (See Figure 20).
6.
Reinstall brush housing if removed.
DANGER:
Operating a machine that is not completely or
fully assembled could result in injury or
property damage. Do not operate this
machine unless it is completely assembled.
Inspect the machine carefully before
operation.
