BATTERY CHARGING
INFORMATION
!
IMPORTANT
This product must be grounded while
charging to protect the operator from electric
shock. The power cord plug MUST be
plugged into a matching electrical receptacle
that is properly grounded in accordance with
ALL local codes and ordinances.
Problem
Machine leaves streaks
Pump will not run
Pump runs when unit is
pulled in both directions
TROUBLESHOOTING
Probable Cause
Pad has excessive debris
Suction line filter blocked
or restricted
Distribution tube is blocked
Floor re-coated too soon
Switch is off
Battery is discharged
Hall Effect switch
Drag on axle needs to be
increased
1. Charge battery by connecting the power cord
to the power inlet on the back side of the
Grand Finale. Connect the power cord into a
120v grounded outlet. The GREEN light will
come on when the power is connected. Allow
battery to charge until "charged" and the RED
indicator light glows. Disconnect power cord
when fully charged.
2. Battery low indicator light on control panel
will glow when approximately 10 minutes run
time remain. Battery run time is 5-7 hours.
Solution
Put pad holder in UP position and remove debris
from pad.
Remove suction line and rinse with hot water.
Remove trough assembly from machine. Remove
distribution tube from trough and clean tube using
clean-out brush or paper clip.
Allow adequate drying time between coats. Burnish
after 24 hours.
Put switch in the ON position.
Test by switching to the prime position. If the pump
fails to run the battery needs to be charged.
If the pump runs in the PRIME position but not
when being pulled, the magnet that trips the axle
position sensor switch may be out of alignment.
Open the body and visually check the nylon hub
(item 22 on the axle. It should be centered in front
of the hall effect switch (item 6). If not, first check
for side play in the axle assembly. There should
only be about 1/32" to 1/16" movement. Adjust if
necessary by tapping the hubs on to the axle.
If there isn't side play then loosen the setscrew in
the nylon hub and move so that it is centered in
front of the hall effect switch. Also check that the
magnet has not come dislodged from the hub.
Check the distance between the hub and the
switch. This should be no more than 1/16".
If this doesn't solve the problem and all electrical
plugs are in place then a faulty hall effect switch
may be the problem.
Open the body and loosen the hex nut
on bumper (item 4). Turn the bumper to increase
the pressure on the axle so that when the left hand
wheel turns in the forward motion, the axle does
not turn but does turn in the rearward direction.
Retighten the locking hex nut and close the body.
