WIRE FEEDER
DRIVE ROLLS AND GUIDE TUBES
After feeding every coil of wire, inspect the drive roll section. Clean as necessary. Do not use a solvent for cleaning the drive rolls because it may wash the lubricant out of the bearing. The drive rolls and Inner Wire Guides are stamped with the wire sizes they will feed. If a wire size other than that stamped on the roll(s) is to be used, the roll(s) and Inner Wire Guides must be changed.
PERIODIC MAINTENANCE
WIRE DRIVE MOTOR AND GEARBOX
Every year inspect the gearbox and coat the gear teeth with grease. Do not use graphite grease. Refer to the Troubleshooting section for disassem- bly of Drive Motor and Wire Feed Assembly.

All drive rolls have two identical grooves. The rolls may be flipped over to use the other groove.
See Procedure to Install Drive Rolls and Wire Guides in the Operation section for roll changing instructions.
WIRE REEL MOUNTING -
No routine maintenance required. Do not lubricate 2 in. (51 mm) spindle.
