Loading Pipe Into Machine
Clean the inside and outside of pipe ends that are to be fused.
Open the upper jaws and insert pipe in each pair of jaws with
applicable inserts installed. Let the ends of the pipe protrude past
the face of the jaws .75" for model 28 and 1.25" for model
250/412.
Move the facer into place. With the carriage control valve lever,
move the carriage toward the fixed jaws while watching the gap
at each end of the facer stops. When the pipe is in contact with
the facer, this gap indicates the amount of material that will be
trimmed from the pipe end. Assure sufficient material will be
removed for a complete face off.

Jaw Configuration
The DynaMc EP 4 jaw machines can be configured to a 2
movable/2 fixed jaw configuration or a 3 movable/1 fixed jaw
configuration. This will allow work in close proximity to ells and
tees without the removal of the outer jaw.
To change to the 3 movable/1 fixed jaw configuration:
Unscrew the knobs on the jaw braces and remove the braces.
Align the brace between the middle 2 jaws. The carriage may
have to be moved to align the brace. Attach the brace with the
knobs to secure them in place.
To change to the 2 movable/2 fixed jaw configuration:
Unscrew the knobs on the jaw braces and remove the braces.
Align the brace between the outer fixed jaw and adjacent jaw.
The carriage may have to be moved to align the brace. A block of
wood should be used on both sides across the guide rods to push
the adjacent jaw with the movable jaws to align with the outer
fixed jaw. Attach the brace with the knobs to secure them in place.
