adapter kit to the existing pump element installed.

Also available, is the optional pump element that is
manually adjusted to various deliveries.

The Adjustable Pump Element is factory set to
the maximum output.
Adjusting may take several attempts to reach
satisfactory delivery. When properly set, a fresh
discharge of lubricant maintains a wet coating that
is visible on the tool shank while working – without
waste. Refer to Figure 6-14.
