tools, with some major differences:
• Serial Code is not WH or YM.
• Movable die is yellow.
• Decal on the handle identifies it as a utility tool.
•“44999” is molded into the rubber covering on the block.

Serial Code YM

2. The fixed die is one-piece steel casting, colored
black.
3. The two arms on the cylinder are not slotted.
4. Serial number begins with “YM” prefix.

The WH series and YM series crimping tools have
several distinguishing characteristics, which are listed
here. But be aware that, since many parts are inter-
changeable, a tool sent to you for repair may be a
hybrid — if it has been repaired previously, it may have
a mixture of parts from the WH series and YM series.
See Retrofit Kits in this manual for an explanation of
interchangeable parts.
Most of the instructions in this service manual apply to
both WH series and YM series. However, some indi-
vidual steps and some procedures apply to only one or
the other, and are so noted.
