7. Periodic Inspection
・
Add grease at least once a day.
・
Fully stroke the jaw before starting work or upon supplying grease, and check that
the jaw is inside the appropriate stroke area.
・
Always clean the chuck body or the sliding surface using an air gun, etc., at the end
of work.
・
Check that the bolts of each part are not loosened at least once every 3 months.
・
Disassemble and clean at least once every 6 months or every 100,000 strokes
(once every 2 months or more for cutting cast metal).
7-2. Grease lubrication
1. Position to lubricate
・
Lubricate using a grease gun from the grease nipple on the body periphery part.
Supply grease when the jaw is open. After lubrication, repeat opening and closing
the jaw several times without gripping work.
2. Grease to use
・
Use the designated grease specified in Table 7. If grease other than the designated
grease is used, sufficient effect may not be obtained.

To keep the chuck running in the best condition for a long time, adequate
grease lubrication is necessary. Insufficient grease lubrication causes a drop
in the gripping force, operation failure at low hydraulic pressure, drop in
gripping precision, abnormal wearing, seizing, etc. The work will fly out due to
a drop in the gripping force and this is dangerous.
