IMPORTANT SAFETY INSTRUCTIONS
When using battery powered machines, basic precautions should always be followed, including
the
following:
READ ALL INSTRUCTIONS BEFORE USING MACHINE
Operate from the rear of the machine only.
Use caution when operating the machine on a ramp or incline.
Do
not turn the machine, or leave it unattended, on a ramp or incline.
~~ ~ ~~ ~~
Machine can cause an explosion when operated near flammable vapors
or materials.
Store machine inside. Keep the electrical components of the machine dry.
Lead acid batteries have a number of inherent dangers, carefully read the
instructions and warnings which accompany the batteries and battery charger.
REMEMBER:
The batteries generate gasses which can ignite. Always
charge in a well ventilated area. Keep sparks and flames away from the
batteries.
Do
not smoke around the batteries. Avoid skin contact with the acid
contained in the batteries. Always wear eye protection and protective clothing
when working on or near batteries. Never allow metal objects to lay across
battery tops.
~ ~~ ~~
All
maintenance and repairs must be done by qualified personnel only.
Maintain adjustments on machine as specified in service manual.
Make sure all warning and caution labels are legible and properly
attached to the machine.
SAVE
THESE
INSTRUCTIONS
Record the model and serial number on the blue data label located at the rear of the machine
.
These numbers are used when calling upon the Windsor dealer for parts and service.

Battery Maintenance:
When cleaning batteries use a solution
of
baking
soda and water.
(Do
not allow cleaning fluid to
enter inside battery cells.)
Keep a proper electrolyte level in battery cells.
Wipe down the battery tops at least once a
week.
If
a
cell
should accidently overflow, clean
immediately.
Test battery condition with a hydrometer at least
once a week.
Ensure that all connections are tight and that
all
corrosion
is
removed.
Every
4
to
6
months remove batteries from the
machine and clean the battery compartment.

Battery Charging Procedure:
Charge the batteries once the amber charge
level
light
comes on.
The
amber light indicates that there is
about
20%
charge
left
in the batteries.
Do
not let the
batterles completely drain before
charglng.
Avoid
charging the batteries before the amber light comes
on.
The
machine will run for hours
on
fully charged,
well
maintained batteries.
DO NOT SMOKE, HAVE OPEN FLAMES,
OR
SPARKS NEAR BATTERIES
AT
ANY TIME.
WARNING:
WEAR EYE PROTECTION AND PROTECTIVE
CLOTHING WHEN WORKING
WITH
BATTERIES.
CHARGE
BAlTERlES IN A WELL VENTILATED
AREA WITH DECK DOWN AND COVER OPEN.
1
.)
Use
a
36
volt, 20 amp maximum output, D.C.
charger which turns itself
off,
when the batteries are
fully charged. The charger must have a connector
that matches the machines battery connection.
2.)
Read the instructions and warnings provided by
the battery charger manufacturer.
3.)
Set the charger
in a well
ventilated area on a lev
-
el
surface. Make sure cords will easily reach outlets
on both machine and wall.
4.)
Connect
charger to
D.C.
outlet on machine
first.
5.)
Connect the A.C. power cord to properly
grounded wall socket.
NEVER MAKE THE A.C.
CONNECTION FIRST, HAZARDOUS SPARKS MAY
RESULT.
6.)
After the batteries are completely charged discon
-
nect the charger from the A.C. wall socket.
7.)
Once the charger is disconnected from the A.C.
wall socket it is safe to disconnect the charger from
the machine.
8.)
When the batteries
are fully charged, check the
electrolyte level by removing
the caps on top of the
batteries.
If
necessary
fill
the
cells with distilled water as
shown in the diagram to the
-
-
right. Be careful not to overfill
cells.

have been done, replace
the
control board.
Replace
fuse
Reset circuit breaker.

Unplug connector coming from main handle assembly. Squeeze
handle and test for continuity at handle end of connector
E.
Adjust or replace switch
as
needed
.

for
exploded
view of switch cover
(F22)
and drive control assemblies

With main power on, pad
in
operating position
and
drive handle
squeezed:
Test
voltage
at
points
F
to
Q
and
F
to
B
should
be
from
34
to
38
VDC. When
the
relay
Is
working
it
should make a
clicking noise
as
the drive handle
is
squeezed. Replace relay
if
the
test
voltages measure properly and
the
pad
motor still does
not run.
If
the test voltages are not
34
to
38V DC, check wiring
and connections at
points F,
Q,
D and
B.
When the brush wear indicator light comes
on
it
is
necessary
to
put a new
set
of
carbon
motor brushes
in.
Caution:
Continuing
to
run the machine
until the brushes wear away completely
will cause motor damage.
Reset
circuit breaker
(M)
Check connections
J1L
J2
and
K3 & K4
on control board
along
with all other connections to actuator.
With
the
main power switch turned on
and
the
pad
upldown
switch depressed, test
voltage
at
K4
to
K3
should
be from
34
to
38
VDC.
If
the voltage is
good
at
K4
to W but the actuator
still
is not operating it will need to be repaired or replaced.
Unplug
the
connector at J on the control board. Test J (coming
from control panel) for continuity when pad switch is pressed.
Replace control panel
if
necessary.
Test voltage
at
L6
to
K7
should be from
34
to
38
VDC.
If
the
voltage
is
good
at
L6
to
K7
but
the
lift mechanism
still
won't
respond,
all
the
tests above have been done, replace the
control
board.
Check for worn out pad.
Check for worn
out
pad.

Condition Corrective Actlon
-
-
Control board stuck in the
self check mode
When the main power is turned on within
3
seconds of the time
that the battery charger plug is removed the control board initiates
a self diagnostic program. To cancel the self diagnostic program
check, simply
turn
off
the main power
switch
for 3 seconds and
turn it back on.
If
the problem persists, turn
Ow
the main
switch
and
remove the 3 amp fuse for 5 seconds. Replace the fuse and turn
on the main switch.

Circuit Breaker tripped
Loose connections
Faulty micro switch
Faulty potentiometer
Faulty drive control board
Faulty motor

Reset
circuit breaker
(W).
Check
all
connections in propel motor drcuit especially
at
P,Q,R,
V and
X.
With the batteries disconnected, disconnect the wire leads to the
micro switch, at
V, and test for continuity. When the
control
levers
are squeezed the micro switch
is
engaged. There
should
be a
slight clicking sound when the switch is engaged.
Adjust
or
replace
as
necessary.
With the drive motor disconnected at
Q
or
X
test
the
output
voltage
to the drive motor. THe output voltage
at
Q
or X should vary
from
0
to
24
volts
as
the potentiometer U on the controls
is
adjusted and the control levers are squeezed. Resistance
of
the
potentiometen
can
be
tested at
the
green
and
black
leads
found
at
the molex connector at
R.
The resistance should vary from
0-
to
2.2
kilo ohms
as
the potentiometer U on the controls
is
adjusted
with the control levers
squeezed. If these fail, the potentiometers
will both
need
to
be
replaced.
Test
voltage at P should be from
34
to
38
VDC.
If
the voltage at
P
is
good
but
the propel motor won't respond, and all the tests
above have
boen done, replace the drive control
board.
Squeeze the control Ievem,
adjust
the potentiometer
U,
and test
the voltage at
X
or
Q.
When the output voltage at
X
or
Q
varies
from
0
to
24
volts but the motor does not respond, and all the tests
above have been done, replace the motor.
