Please be sure to lubricate the metal gears before running the

gearbox at high power and after every hour of use. Any light grease will

work fine. We use bike grease or white lithium grease. Make sure there is

proper clearance between the gears. To set the clearance place a narrow

strip of computer paper between the pinion and spur gears,press the gears

together, then tighten the mounting screws. Then turn the shafts to eject the

paper strip and go play!
