5. CLEANING AND MAINTENANCE
Riveting for a long time generates chips and dust at several parts, which causes troubles.
The tool needs periodical cleaning and maintenance according to this manual.
Before cleaning and maintenance of each part, make sure
that the power of air compressor is turned off to stop air
supply and eliminate the residual pressure. Otherwise, you
may be injured.
• When assembling each part, apply lubricant agent such
as grease at each sliding area without fail. Otherwise,
malfunction may occur.
• All parts must be completely assembled and all fastening
areas must be fastened.
5.1 FRAME HEAD AND JAW CASE UNIT
If chips are clogged, jaw cannot work smoothly. Cleaning must be performed in every 3000
times of crimping.
• Jaw is a consumable supply. It must be replaced periodically.
This tool uses high-endurance hard tool material jaw (optional
parts). When you order the part, order “hard tool material jaw,
medium”.
• Do not loosen or remove an oil retaining screw. The oil
retaining screw is used for air vent during assembly.
• Do not loosen or remove a jaw case or lock nut of jaw case. If
it is loosened or removed, oil is leaked from head area, which
cause malfunction. Jaw case and lock nut of jaw case are
mounted at screw unit of oil piston so that they are not
loosened. If they are accidentally loosened during operation
or during maintenance, ask repair.
