■ 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.
• When removing and installing the cutter
holder(a), use care not to allow any dirt and dust
entering in to the gear case.
