7. Using the sequence illustrated here, pump the
handles to advance the dies. Continue to pump
until the pressure relief valve activates.
Note: Pressure relief occurs at approximately
106 kN (12 tons) and is indicated by an audible
"pop".
8. Release pressure by twisting the pump handle
clockwise in the open position and closing the
handle to activate the release valve.
9. When using KC12-type dies, complete the number
of crimps listed on the "Connector Selection" chart
in this manual. For other dies, complete the number
of crimps specified by the manufacturer.
10. Remove connector from crimping tool.

Periodic Pressure Relief Valve Check
Keep hands away from the crimping
tool head when crimping.
Failure to observe this warning could
result in severe injury or death.
The crimping tool's relief valve may require occasional
adjustment. To determine whether this adjustment
is necessary, periodically test the crimping tool with a
Greenlee model 35887 Load Cell (purchased separately).
1. Insert the test dies into the tool (refer to steps 3
and 4 under "Operation" in this manual). Position
the load cell so that the load cell piston is centered
between the two test dies.
2. Pump the lever until the crimping tool achieves
pressure relief, and note the position of the needle
when the pressure relief is achieved. The needle
should indicate the "12T" range. If the needle is
outside of this range, send the crimping tool to an
authorized service center for adjustment.
Note: If some other type of load cell is used, the ratio
between the area of the tool and the area of the load
cell may be different. The appropriate corresponding
pressure range depends upon this ratio.
