Stanley Black & Decker CT04 Pre-Operation, Setup and Test, Open CENTER/CLOSED Center Setup

OPERATION

PRE-OPERATION

Careful inspection of the tool and hydraulic system be- fore startup is important for safe, reliable operation of the tool.

The following items should be checked daily at the start and the end of each work shift.

Cylinder Open-Center (no gap)

1.	Make sure the proper dies are securely in place. Op-
	erating the tool without dies can deform the crimping
	heads. Refer to Die Installation for instructions.
2.	Connect hoses. Wipe all hose couplers with a clean,

Adapter

Trigger Handle

	lint-free cloth before making connections. Dirty cou-
	plers can contaminate the hydraulic lines and pre-
	vent a good seal at the connection.
3.	Check all fasteners for tightness.
4.	Check the equipment for oil leaks. If leaks are ob-
	served, do not use the tool; have the equipment ser-
	viced before use.
5.	Check the tool and hydraulic system for proper op-
	eration and performance.
6.	If the equipment does not appear to operate prop-
	erly, have it serviced before use.
7.	Periodically verify the crimping force of the tool. Re-
	fer to Die Load Verification.

SETUP AND TEST

•Never operate the tool without dies. Operating with- out dies can deform the crimping head (retainer die yoke or C-frame).

•If this happens, the dies cannot be installed and the crimping head must be replaced.

•Never install the dies while the hydraulic hoses are connected to the tool.

•Verify the crimping force before operating the tool.

OPEN CENTER/CLOSED CENTER SETUP

The CT04 Hydraulic Crimping Tool can be configured for either open-center or closed-center operation. The current setting is easily determined by looking at the gap between the adapter and the cylinder:

TO CHANGE THE CURRENT SETTING:

1.Remove the hydraulic hose coupling from the return port on the tool, if one is installed. When making the change from CC to OC, hydraulic fluid may be trapped in the tool, preventing complete movement of the adapter. Remove the return coupling to allow the hydraulic fluid to escape.

2.Loosen the 2 setscrews on the cylinder.

3.Turn the adapter until it stops:

•Counter Clockwise (CCW) to change to closed center (creates gap)

•Clockwise (CW) to change to open center (clos- es gap)

4.Tighten the two setscrews.

DIE INSTALLATION

Each crimping head has two die holders: one station- ary and one moved by hydraulic flow when the trigger is squeezed.

To install dies, follow the instructions below for your model of crimping head.

WARNING

Installing dies in the tools with the hydraulic hoses connected can cause severe personal injury or equipment damage.

To prevent accidental start-up, always disconnect the

hoses before installing dies.

1.If the hydraulic hoses are connected:

•Turn the hydraulic system control valve OFF.

•Disconnect first the hydraulic input (supply) hose, then the output (return) hose.

2.Clean the surfaces of the die holder to remove any dirt or grease.

3.Select the dies for the task:

•If the die load has not been verified, select blank dies and verify die load.
