9. Maintenance (EX-PS only) The bar rail should always be a square. Check for wear of the bar rail. Apply a ruler to the bar and the outside of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be corrected or replaced.
42 9. Maintenance (EX-PS only) After every cutter has been set, check the depth gauge and file it to the proper level as illustrated. (MA7) Be sure to round off the front edge to reduce the chance of kickback or tie-strap breakage.
9. Maintenance (EX-HE only) ■ GEAR CASE • The reduction gears are lubricated by multipurpose, lithium-based grease in the gear case. At every 20 hours of use, supply the gear case with new grease. • Remove the cutter holders before installing new grease to arrange for old grease to exit.
