ROUTINE MAINTENANCE
DRIVE ROLLS AND GUIDE TUBES
After feeding every coil of wire, inspect the drive roll section. Clean it as necessary. Do not use a solvent for cleaning the idle roll because it may wash the lu - bricant out of the bearing. The drive roll, idle roll and guide tubes are stamped with the wire sizes they will feed. If a wire size other than that stamped on the rolls is to be used, the rolls and guide tubes must be changed.
The drive rolls for .035 through .052 cored electrode and 1⁄16 through 5⁄64 electrode have a double set of teeth so they can be reversed for additional life. Drive rolls for .023 through .052 solid electrode and aluminum sizes have no teeth but use two grooves so they also can be reversed for additional life.
See Wire Feed Drive Roll and Guide Tube Kits Sec - tion for roll changing instructions.
WIRE REEL SPINDLE
No routine maintenance required. Do not lubricate spindle.
