for possible shipments in the future. Gamma Sports cannot be responsible for
machines that are not returned, in their original, undamaged packaging. The tools you will
need to assemble the 6500 Els are provided with the machine. Due to the weight of the
tensioner unit, you may need the assistance of someone to help lift the tensioner unit out
of the carton.

design. The legs must be assembled to the
support post before use. Remove the lower
column support, the upper column support,
four(4)legs,four(4)socketheadcapscrews
and four (4) flat head cap screws from the
small shipping carton.
BaseLeg Assembly (Cont.)
Align the holes in the leg flange with the
matching holes in the lower column support
post. Secure the leg with one FLAT HEAD
cap screw through the upper hole, and one
SOCKET HEAD cap screw through the bot-
tomhole.Repeatthisprocedureforthethree
remaining legs.
ASSEMBLYINSTRUCTIONS
BaseLeg Assembly (Cont.)
To complete the base stand, screw the height adjust-

ClampHeadInstallation
The post of the string clamp head and the tube of the string
clamp base are treated with grease to provide protection
against corrosion during shipping. Remove any excessive
grease with a clean cloth prior to use. The post and tube may
also be cleaned with isopropyl alcohol. After this type of
thorough cleaning, the post and tube should be treated with a
light coating of machine oil to protect the surfaces against
corrosion and to ensure smooth operation.
InstallingtheTurntable
Remove the nuts from underneath of the
turntable and leave the screws in position.
Align the four (4) holes in the center of the
turntable with the four (4) holes on the
turntablepin. Tightenthemsecurelywiththe
6mm allen wrench.
ASSEMBLYINSTRUCTIONS

STRINGREELHOLDERINSTALLATION
Thestringreel holderpinisan8mmrodwith
threads on both ends, and flat surfaces
machinedonone end. Thread the endof the
pinwithouttheflatsurfacesintothethreaded
boss on the right side of the lower column
support. Using the M6 open end wrench
positioned on the flat surfaces, securely
tighten the pin to the lower column support.
The string reel holder can hold up to 5 reels
of string (depending on the size of the string
reel). Before placing the first reel on the pin,
slide two M8 washers over the pin and slide
them to the boss on the lower column sup-
port.Afterthefirstreel is placedontothepin,
place two spacers between each reel to
provide enough space between reels and
allow them to turn freely without rubbing
against one another. (To provide a smooth
feed to the String Length Meter, place the
reels on the pin so the string spools off the
reel from the underside of the reel.)
After the last reel is installed, place the
remaining spacer(s) on the pin and attach
the threaded knob to the end of the pin.

SLMFACEPLATE INSTALLATION
Remove the tape covering the opening on
the front side of the bottom cover to expose
the string length meter.
Position the face plate assembly over the
opening in the bottom cover, and align the
two countersunk end holes of the face plate
with the threaded attachment holes in the
front of the string length meter. With the two
flat head machine screws, secure the face
plate assembly to the string length meter.
To check for proper alignment, lift the top
clamp of the face plate assembly and insert
a section of racquet string at least 12 inches
long into the entrance hole of the face plate.
Continue feeding the string section into the
string length meter, until it appears through
the exit hole. If the entrance or exit holes
appeartobeblocked,loosentheattachment
screws and adjust the position of the face
plate assembly until the section of string
exits the face plate. After the face plate is
properlyaligned,tightentheflatheadscrews.

Instructions for Power Connection (Refer to Figure 1)
CAUTION ! Before connecting to the power supply, check the voltage supply switch
setting located on the side panel as shown in Figure 1. To change from 115 volts service
to 230 volt service simply slide the switch fully to the top or to the bottom until “115V” or
“230V” appears on the switch plate.
The acceptable range of input voltages for the “115 V” setting is between 110 V and 120
V @ 60 Hz and for the “230 V” setting, between 220 V and 240 V @ 50 to 60 Hz. If you
have any question regarding the input voltage supply for your area, please ask your
electric utility company.
To install the power cord, insert the female end of the power cord into the Power Cord
Socket located on the side panel and plug the male end into a grounded power outlet.
When using extension cords, use grounded heavy duty extension cords rated for 15
AMP service. To connect the foot pedal switch, insert the 2 pin male connector located at
the end of the foot pedal switch cord into the two pin receptacle located on the back
panel. Tighten the connector with the sleeve nut located on the foot pedal switch
connector.
After checking to be certain that the machine is set for the correct input voltage, switch
on the machine by pressing the Lighted On-Off Power Switch on the side panel.
