ASSEMBLY INSTRUCTIONS Floor Stand Base Assembly The stringing machine uses a pedestal floor stand design that can be set up to orient the machine perpendicular to the operator or to position the machine on an angle. The base plate must be assembled to the lower column before use. Remove all parts from the shipping carton to confirm that contents match the list of parts on Page 4.
ASSEMBLY INSTRUCTIONS Floor Stand Height Adjustment The height of the machine is adjustable from 39” to 46” in approximate 1” increments. To change the height, remove the socket head cap screw from its current position and place it in the appropriate hole to set the desired height of the machine.

STRING REEL HOLDER INSTALLATION The string reel holder pin is an 8 mm rod with threads on both ends and flat surfaces machined on one end. Thread the end of the pin without the flat surfaces into the threaded boss on the right side of the lower column. Using the M6 open end wrench positioned on the flat surfaces, securely tighten the pin to the lower column.

MACHINE FUNCTIONS Setting Tension It is possible to set tension values so the main string and cross strings are pulled at the same tension or at different tensions. Pressing the MAIN/CROSS String button will toggle between the Main String and Cross String Settings and the tension value for the highlighted icon will be the large tension numbers on the display.
Page 13
MACHINE FUNCTIONS Pre-stretch Function The Pre-stretch function is used to pre- stretch strings on each pull by increasing the applied tension by a certain percentage over the tension setting before releasing the string and re-pulling to the desired tension. This function helps to reduce the amount of tension loss in the strings over time.
