[Remarks: Replacement of grease]
Since grease is filled in the gear section of the tool unit, it is not necessary to replace grease in short
intervals. However, the durability of machine parts, such as gear section, is increased if the grease is
replaced with new every 3 years. In that case, ask us for overhaul (at your cost).
