Maintenance
It is recommended that each operator of
the tool be made aware of, and responsible
for, the following maintenance steps:
1. Remove dust, moisture, and other
contaminants with a clean brush,
or soft, lint free cloth.
2. Do not use any abrasive materials
that could damage the tool.
3. Make certain all pins; pivot points
and bearing surfaces are protected
with a thin coat of high quality
machine oil. Do not oil
excessively. The 64001-4800
(RHT-2251) was engineered for durability, but like any fine piece of equipment it needs
cleaning and lubrication for a maximum service life of trouble-free crimping. A light oil, such
as 30 weight automotive oil used at the oil points shown in Figure 4, every 5,000 crimps or 3
months will significantly enhance the tool life and ensure a stable calibration.
4. When tool is not in use, keep the handles closed to prevent objects from becoming lodged in the
crimping dies, and store the tool in a clean, dry area.
Miscrimps or Jams
1. Should this tool ever become stuck
or jammed in a partially closed
position,
Do Not force the handles
open or closed
. The tool will open
easily by lifting the ratchet release
lever (See Fig.5).
How To Adjust Tool Preload (See
Figure 5)
Over the life of the tool, it may be
necessary to adjust tool handle preload
force. Listed below are the steps required to adjust the crimping force of the hand tool to obtain proper
crimp conditions:
1. Remove the screw and plastic cover washer. Note the setting wheel position.
2. Lift the setting wheel off the axle. Turn the eccentric axle with a screwdriver.
3. Turning the eccentric axle counter-clockwise (CCW) will increase handle force.
4. Replace the setting wheel to the axle, aligning the nearest notch in the setting wheel to the dowel
pin.
5. Replace the plastic cover washer and screw.
6. Check the crimp specifications after tool handle preload force is adjusted.
