IMPORTANTSAFETY INSTRUCTIONS
When using battery powered machines,basic precautionsshould always be followed, including the following:
READALL INSTRUCTIONS BEFORE USING MACHINE
Operatefrom the rear of the machineonly.
Usecautionwhen operatingthe machineon a rampor incline.
Do not turn the machine,or leave it unattended, on a rampor incline.
~~ ~ ~~ ~~
Machinecancause an explosionwhen operated near flammablevapors
or materials.
Store machine inside. Keepthe electrical components of the machinedry.
Leadacid batteries havea number of inherentdangers, carefully readthe
instructionsand warnings which accompanythe batteries and batterycharger.
REMEMBER: The batteriesgenerategasseswhich can ignite. Always
charge inawell ventilatedarea. Keepsparks andflames away fromthe
batteries.
Do not smoke aroundthe batteries. Avoid skincontact with the acid
contained inthe batteries. Always wear eye protectionand protectiveclothing
when working on or near batteries. Never allow metalobjects to lay across
batterytops.
~ ~~ ~~
All maintenanceand repairs must bedone byqualifiedpersonnelonly.
Maintainadjustmentson machineas specified inservice manual.
Makesure allwarning andcaution labelsare legibleand properly
attached to the machine.
SAVE THESE INSTRUCTIONS
Recordthe modeland serial number on the bluedata label locatedatthe rear of the machine .

Battery Charging Procedure:
Chargethe batteriesoncethe amber charge level light
comeson. The amber light indicatesthat there is
about 20% charge left inthe batteries. Do not letthe
batterlescompletely drainbeforecharglng.
Avoid
chargingthe batteriesbeforethe amber light comes
on.
The machinewill runfor hours on fully charged,
well maintainedbatteries.
DO NOT SMOKE, HAVEOPEN FLAMES, OR
SPARKS NEAR BATTERIES AT ANY TIME.
WARNING:
WEAR EYE PROTECTIONAND PROTECTIVE
CLOTHING WHEN WORKING
WITH BATTERIES.
CHARGEBAlTERlESIN
A WELL VENTILATED
AREA WITH DECK DOWNAND COVER OPEN.
1 .) Use a 36 volt, 20 amp maximumoutput, D.C.
chargerwhichturns itself
off, whenthe batteries are
fully charged. The charger must havea connector
that matchesthe machinesbatteryconnection.
2.) Readthe instructionsandwarnings providedby
the batterycharger manufacturer.
3.) Set the charger in a well ventilatedareaon a lev -
el surface. Makesurecordswill easily reach outlets
on bothmachine andwall.
4.) Connect chargerto D.C. outlet on machine
first.
5.) ConnecttheA.C. powercordtoproperly
groundedwallsocket.
NEVER MAKETHE A.C.
CONNECTIONFIRST, HAZARDOUSSPARKS MAY
RESULT.
6.) After the batteriesare completelychargeddiscon -
nectthe chargerfrom the A.C. wall socket.
7.) Oncethe charger isdisconnectedfromtheA.C.
wall socket it is safeto disconnectthechargerfrom
the machine.
8.) Whenthe batteries
arefullycharged,checkthe
electrolyte levelby removing
the caps ontop of the
batteries.
If necessary fill the

ACTUATOR REMOVAL
1.) Switch on main switch and lower buffing
head to floor. Switch off main switch.
2.) Removemain cover and batteries.
3.) Lay machine on left side.
4.) Remove actuator connecting lift link ##42 on
page 11.
5.) Disconnect motor leads. ,
6.) Remove (4) bolts holding actuatorbracket
to frameand
lift out actuator.
TestingActuator Barrel ’Iz.avel:
1.) Donot allow the barrel to rotateorthe
1/2”-9/16” (1,25 to 1,4 cm) adjustmentwill be
lost).
2.) Connectwhite wire to the (+) positivepost and
the black
wire to the ( - ) negative post of the
36VDC power supply to retract the barrel to the
lower limit.
3.) Black wire to the (+) positive post and the
whitewire
to the ( - ) negative post of the 36VDC
power supply to extend the barrel to the upper lim-
it.
4.) Reverse the wires to retract the barrel electrical -
ly. the actuator is now ready for assembly and
installation.
LIMIT SWITCH SETTINGS
Lower Adjustment
1.) Connect the white wire to the ( - )negative
post
of a 36VDC power supply and the black
wire to the (+) positive post. This will retract or
close the actuatorbarrel. Maintainthe connection
until the limit switchshuts the power off.
2.) Disconnect both wires from the power supply.
Set
“A” (barrel to frame gap) at between 1/2 and
9/16
of an inch (1,25 to 1,4 cm) rotating by hand.

Rw.1 7m
Upper Adjustment
1.) Hold Barrel With Hand
power supply,white wire to the (+) positive post
and the black wire
to the ( - ) negative post. This
will extend or open the actuatorbarrel.
Reverse the wire connections
to the 36VDC
Do not allowbarrel to rotate.
2.) Extend actuatorbarrel electrically until it
stops. Ensure
“A” is between 3 3/4 and 3 7/8 in -
ches (95to 9,9 cm) on all models.
3.) If the dimensionisincorrect, disconnectfrom
thepower supply and setthe switch cam adjust
-
ment.
Switch Cam Adjustment
1.) Remove the two cam switchcover screws
(TOM T15) and remove cam switch cover.
2.) Loosen the two cam lock screws (TORX “20)
on the cams.
CAUTION:
Do not allow retract cam to rotate.
3.) If the “A” dimension is incorrect,turning the
cam clockwisewill INCREASE
“A, counter-
clockwise
will DECRBASE “A”.
4.) Tighten the two cam lock screwsand cyclethe
actuator.
Do Not Allow TheBarrel To Row.
Check the extended “A” dimension. If itiscor -
rect, replace the coverwith screws. If not repeat 3
