Excessive travel
Check all pulls on pedal or knee lever and follow tuning procedures section, removing excess slack.
Slippage
Slippage on cross shafts should not occur. If it does the component needs to be re-torqued. Look at shaft in question. If only one bell crank is out of alignment with the others, loosen its pull rod and loosen the bellcrank, re-align, then carefully tighten It. (You can test this by hand against the other.)
If all bell cranks are not close to 90’Δω from body, the pedal arm or knee lever hub has moved. If this is the condition, reposition and tighten.
Lubrication
It is advisable every three months to sparingly apply lubricant to bell cranks, nylon barrels, underside of the changer mechanism and most important to the right moving knee lever ball joint knuckles. Do not over-lube, as dust and dirt will adhere to the lubricant.
Strings
Two things to check periodically: string alignment through nut rollers. Tension screw on the Grover tuning keys, Royalty models, must be tight enough to avoid tuning key slippage.
Adjustments
Both the front and rear legs are adjustable for height, although custom leg sizes may be special-ordered for people who want shorter or longer inserts to accommodate them.
Front: loosen setscrews on square leg portions. Re-adjusting this might cause you to have to readjust pedal rods.
Rear: quick release butterfly knob-in-groove.
Pedal rods
Loosen nuts at either clasp to shorten or lengthen.
The gap between the left and right knee levers on either leg may be narrowed or widened by moving mobile knee levers.
Loosen all pull rods 3 or 4 turns on that knee lever.
Loosen plate cover (A).
Loosen (D) at the 10/32 nut through (E) to close the gap.
Reset position of (A) while holding (F) straight up 90¬ƒ.
Tighten (A)
Re-tighten all pull rods property and re-tune.
