Use high efficiency PTFE grease (part number T-400-G for 4 oz tube, FF91455
for 16 oz can)
Die Cage Maintenance Procedures
1.
Lubricate the die cage. For maximum service, FT1380 die cages require
lubrication at 50-crimp intervals with high efficiency PTFE grease.
FF91455 is a 16 ounce container that will provide sufficient lubricant
for about 10,000 crimps.
Periodically remove grease residue that has built up on the sides of the
dies and in the crimp ring during the crimping process. Residue becomes
contaminated with metal and plating chips and airborne contaminants,
which can cause premature wear of the dies and crimp ring. It should
carefully be removed without mixing it with newly applied grease.
2.
Die cage maintenance should be performed at 1000- crimp intervals
or every six months, whichever occurs first. Die cages should be free of
grease and debris and inspected for worn or damaged components.
a.
The sliding surface of the dies should appear smooth with no
apparent galling. Galled dies must be replaced. Individual dies in
a cage can be replaced without replacing all eight dies.
b.
Replace springs that show any sign of damage or collapse such
as those which are shorter than the other springs.
c.
The spring plate should appear smooth with no apparent galling.
Galled spring plates must be replaced.
d.
Inspect remaining components, and replace those that are badly
worn.
Reassemble components, and liberally apply high efficiency PTFE grease
to the die surface which slides along the spring plate. Torque the die cage
bolts to 50 in. -lbs.
Ensure that all dies slide in and out freely.
Maintenance Procedures
Machine Maintenance Procedures
1.
Sliding surfaces must be kept free of dirt and other abrasive materials.
2.
All exposed black metal surfaces should be coated occasionally with a
light film of oil to prevent corrosion.
3.
Periodically check the oil level in the fluid reservoir of the hydraulic
power unit. Maintain the oil level according to the indicator on top of
the reservoir. Add ENERPAC hydraulic oil as needed.
Note:
Completely retract the crimp ring when checking the oil level.
