TIGHTENING WHEEL NUTS: During initial operation of the NitroGro applicator, tighten standard 3/4" wheel studs and nuts to torque

400 ft-lbs and tighten 1/2"-20 gauge wheel studs and nuts to torque 80 ft-lbs. Check for proper torque after every 10 hours of use.

Failure to do so may damage wheel nut seats. Once seats are damaged, it will become impossible to keep nuts tight.
