MOUNTING THE FRAME
Adjusting the Frame Support Posts
Place the racquet frame over the center support slide and onto the frame support. Loosen the lever lock bolt on one support post. Slide the post outward until the center support of the racquet support slide is posi­tioned near the inside surface of the racquet frame. Securely tighten the lever lock bolt.
Adjust the opposite post using the same procedure.
Caution: To avoid racquet damage, the sup­port slide should not contact the racquet prior to fixing the support posts.
Shoulder Support Adjustment
The shoulder supports on the 7000Es are adjustable to provide support to the racquet frame. Loosen the knurled knob at the bottom of the shoulder support and swivel the sup­port so that the pads will contact the frame squarely when the arms are closed against the racquet. Should the shoulder supports block string holes, adjust the position of the racquet between the arms until the shoulder supports contact the racquet between grom­met holes.
Securing the Shoulder Supports
Secure the racquet frame with the shoulder supports by rotating the large adjustment knobs on the outside of the support post assemblies clockwise. Adjust the supports until firm contact is made between the shoul­der supports and the frame.
The tear drop shaped holes torwards the back of the shoulder supports are handy for holding the loose end of the string while pulling the string through the racquet. Simply insert the loose end into the tear drop shaped holes and slide the string into the point of the hole.

MOUNTING THE FRAME
Support Slide Adjustment
Once the frame support posts are secured, lightly tighten the support slides by turning the knobs on the outside of the slides clock­wise. Adjust the slides in equal increments until slight resistance is felt.
Apply a final adjustment to all racquet sup­port points until the racquet is firmly secured in the mounting system.
Should the frame supports lose contact with the frame while stringing, they should be adjusted, as needed, to maintain contact with the frame.
Setting Tension
The 7000 ES stringing machine utilizes a rotary adjusting knob along with a digital L.E.D. display to indicate the set tension. To set the tension, rotate the adjustment knob clockwise to decrease the displayed ten­sion, counter-clockwise to increase the dis­played tension, until the desired tension is displayed on the digital display.
Setting Tensioner Speed
To maintain consistency in stringing tension for all types of strings, the 7000 Es can be set to pull at a fast or slow tensioning speed.
When pulled at high speed, stiff Aramid fiber and Metallic strings will generally string up 4-5 lbs tighter on the 7000Es than synthetic or natural gut strings. Therefore, when string-

ing with Aramid (Kevlar, Technora) hybrid strings or metallic strings, the tensioner speed switch, located on the side panel, should be set to the slow pull position.
This decreases the motor speed by one half

STRINGING THE FRAME
Fixed Clamp Operation
The fixed clamps supplied with your GAMMA 7000Es are of a dual action design. The string clamp and the clamp base operate independently of one another.
To clamp a string, lift the clamp head and place the string between the jaws. Depress the clamp head lever to secure the string. The clamping pressure applied to the string should be adjusted to provide sufficient pres­sure to secure the string when subjected to the desired pulling tension. The diamond

Fixed Clamp Operation
Rotate the winged lock knob clockwise to secure the clamp base to the turntable.
Reverse the clamping procedure to unlock the string clamp.
The winged lock knob should be tightened enough to prevent clamp base slippage on the turntable, when the desired tension is placed on the string. To go from the loose position to the clamped position and back, generally requires about 1/2 to 3/4 quarters of a turn. Although when stringing at ex­tremely high tensions, additional tightness
String Gripper Operation
To insert the string in the split drum string gripper, wrap the free end of the string clockwise around the gripper drum and po­sition the string between the gripper jaws as shown in the illustration.
The string must pass over the top half of the gripper before being placed between the diamond coated plates of the upper and lower gripper jaws. Excessive slack in the string should be removed before applying tension. As the drum turns and applies ten­sion to the string, the upper jaw is forced down to clamp the string between the jaws.

STRINGING THE FRAME
Clamping the First Main String
To begin stringing the main strings, insert the two ends of the string through the two center holes at the appropriate end of the frame and continue through the center holes on the opposite end of the racquet.
Secure one of the strings using a string clamp and insert the free end into the string gripper.
Tensioning the First Main String
With the string properly inserted in the string gripper, and the tensioner speed selected, press the Tension Switch once and the string gripper will rotate and slowly apply tension to the string. When the set tension has been attained, the gripper will stop rotating and red LED will go out and the the green LED turn on. As the tensioned string stretches, the gripper will rotate intermit­tently, to maintain the set tension.
To release the string after clamping, press
backwards to release the string. If the string gripper does not rotate back to release the string, press and hold the Gripper Reversing Switch, located on the end panel. Note : For the Gripper Returning Switch to function properly, the Tension Switch must be in the tension mode. Should the Gripper Reversing Switch not seem to function, press the Tension Switch once and press and hold the Gripper Reversing Switch once again.
the tension switch and the gripper will rotate
Tensioning the First Cross String
Weave the cross strings over and under the main strings being careful to alternate the weave direction of each consecutive cross string so as to be opposite of the previously installed cross string.

Page 14
STRINGING THE FRAME
Once the final cross string is tensioned and clamped, tie off at the appropriate hole speci­fied by the racquet manufacturer.
Remove the strung racquet by loosening the shoulder supports and support slides in small increments until the racquet is free from the mounting system.

P ATHFINDER AWL OPERATION
The Gamma 7000Es includes the new Path­finder stringing awl which creates a pathway between or around strings to make inserting a string through tight gromets easier and quicker.
Insert the awl through the grommet hole in the same manner as for traditional awls. The Pathfinder awl must be in the closed position before insertion.
Once the awl is inserted, pull the handle of the awl outward while holding the tip section in place, leaving the outer sheath in the grommet hole.
Insert the end of the string into the center of the sheath.
While holding pressure on the string, slowly pull the sheath out of the grommet hole to leave the end of the string exposed.

Tension Calibration Procedure
If you suspect that your 7000Es is not pulling the

from the L.E.D. display cover plate cover. Rotate screw (“L”) in small increments until the displayed tension matches the tension indicated on the calibrator. Set the machine tension to 80 lbs. and apply tension to the calibrator. If the measured tension is innacurate, rotate screw (“H”) in small increments until the displayed tension matches the tension indicated on the calibrator. Since adjustment of the “L” screw at 20 lbs can influence the tension at 80 lbs and visa versa, repeat these steps until the set tension matchs the tension reading of the calibrator at both 20 and 80 lbs. Replace the 2 caps in the L.E.D. display cover plate.
Please note that there will be a range of tension from the maximum tension at which the tensioner stops pulling (high end of the range), to the minimum tension at which the tensioner starts pulling again (low end of the range). This difference between the high and low end of the range can vary from 2-4 lbs depending on the string used to calibrate the machine and the speed of the tensioner. For consistency, we recommend that the tension setting of the machine be calibrated as close as possible to the high end of the range, using the fast pulling speed and a synthetic string, which is the method used at the factory. Using this method will be the most consistent and will also insure that the racquet will not be over tensioned.

correct tension, you should check the tension with a Gamma Tension Calibrator which provides a measurement of the actual pulling tension being applied by the machine.
With the machine set for the fast pulling speed, and the tension set at 20 lbs., place one end of a calibrator equipped with synthetic string into a string clamp. Place the opposite end into the string gripper and apply tension. If the measured tension is inaccurate, remove the 2 small caps
Adjusting the String Clamps

direction. If the clamp leaves impressions or damages the string, it may be excessively tight and should be adjusted by turning the hex screw counter clockwise to open the gap between the jaws. The clamp jaws should be cleaned periodically to be free from dirt, oil, and any string coating for them to grip properly.
Note: The string clamps supplied with your Gamma stringing machine can accomodate tight string patterns such as badminton. Depending on the string pattern, the clamp may spread the strings slightly which will not compromise the quality of the string job.

CARE and CLEANING
With time and use, the clamping surfaces of your machine may become oily or dirty and result in string or clamp slippage while stringing. Periodic cleaning of the following parts is recommended.
String Clamps
Clean the inside gripping surfaces of the string clamp jaws by inserting a cloth or pipe cleaner soaked with isopropyl alcohol between the jaws and rub back and forth. If the build-up is excessive, dismantle the string clamp jaws to expose the gripping surfaces by removing the adjustment screw. Using a small nylon brush, (such as a toothbrush), scrub the inside surfaces until all debris is removed. Clean the jaws with isopropyl alcohol and re-assemble.
String Clamp Base
Clean the base of the clamps and the top of the turntable with isopropyl alcohol.
String Gripper
Clean inner gripping surfaces with isopropyl acohol soaked cloth or pipe cleaner.
