Use care to set springtension as directed for best performance. Figure 5 StraightedgeBrake Knob Brake Knob Rear Brake Knob Stretch spring to 2." in lengthfor proper tension Center spring on board 13. Excess wire can be trimmed off leavingseveral inches for future adjustment. Figure 6 ADJUSTMENTS To Adjust Parallel Position: 1. Be sure all three brake knobs are free and loose. (See Figure 5 on previous page for brake locations.) 2. Grasp one end of straightedge and hold firmly against drawing board. 3. Gently pivot other end of straightedge up or down until desired parallel position is reached. 4. Secure wire under thumbscrew brake in upper right corner to maintain parallel. To Lock Straightedge In Place: 1. With straightedge in desired position, gently tighten both left and right thumbscrew brakes. Caution: Do not overtighten. Overtightening brake screws will damage wires. Diagram 1 Diagram 2 Brake Screw REWIRING INSTRUCTIONS If your wire ever breaks or needs to be replaced, follow these steps: 1. Release left and right end caps by removingscrews from below. Be sure not to remove screws that keep top and bottom layers of blade together. 2. Remove all old wires. 3. Fold new replacement wire in half and threadfolded end through center of blade. Pull throughuntil wire is equal length on each side of the blade. Cut wire at fold. There are now two independent wires running through blade. 4. Grasp either wire on left side, pass around blade pulleyand brake screw as shown in wiring Diagram 2and pass it around pulley in upper left corner of board. Connect to spring at top. 5. Grasp the wire on right side not connected to springfrom left side. Trial and error method will be requiredhere. Pass this wire around blade pulley and brakescrew, then pass it around pulley in upper right cornerof board. Connect to spring at top. 6. Pass lower left and lower right wires around bladepulleys and brake screws as shown in wiringDiagram 2. 7. To confirm wires have been strung correctly, hold straightedge in place with one hand and pullgently on lower left wire with other hand. The spring at top should move to the right. Repeat by pulling thelower right wire and the spring should move to the left. 8. Replace end caps and secure with screws frombelow. Be sure that wires remain properly threadedaround pulleys and brake screws and pass properlythrough exit slots in end caps. Do not over tighten orstrip screws. 9. Follow steps 8 through 13 on previous page to finish installation.
