Installation
Operation
When disassembling the die head, loosen the locking
handle first, and disassemble the die head.
1. Select an appropriate die head.
2. Install the selected die head into the hydraulic housing
clockwise until the end face of the die head is aligned
with that of the hydraulic housing. Then use a wrench to
tighten it. See Fig. 1.
1. Prepare tube ends by deburring.
Note: Remove any burrs. Use of FITOK Tube Deburring
Tool is recommended.
2. Put a nut, a rear ferrule and a front ferrule onto the
tubing in proper sequence and orientation. See Fig. 2.
3. Insert the tubing into the die head until it rests firmly
against the piston shoulder. Tighten the nut until finger-
tight. See Fig. 3.
4. Make sure that the bleed valve is in the closed position.
While holding the tubing against the piston shoulder,
press the pump handle gently till the gauge shows the
corresponding pressure value. Hold for more than 30s.
See Fig.3 and Table 1.
3. Turn the locking handle clockwise to the finger-tight
position to ensure the die head is firmed. See Fig.1.

1. If it is difficult to remove the tubing from the hydraulic
presetting tool after presetting, rock the tubing back
and forth.
Refer to the Recommended Minimum Wall Thickness
table - presetting tubing below the recommended
minimum wall thickness may result in tube sticking.
Troubleshooting
5. Open the bleed valve. Loosen the nut and remove the
tubing from the hydraulic presetting tool.
6. Install the preset assembly into the fitting body and turn
the nut onto the fitting body until it is -tight.
While holding the fitting body steady, tighten the nut
1/4 turn with a wrench for tube O.D. 1/2", 9/16", 3/4",
and 1/2 turn for tube O.D. 1". See Fig. 4.
finger
Do not rotate the tubing.
Use of tubing below the recommended minimum wall
thickness may result in the tube sticking in the die head.
2. If the die head piston is binding, contact FITOK Group or
authorized distributors.
3. If the pump fails to build pressure, check the oil level in
the pump by removing the dipstick and checking for a
proper amount of oil. Too much or too little oil will
prevent the pump from operating properly.
4. The pump manufacturer specifies using 10W, AW-46
grade hydraulic oil or equivalent with an antifoaming
additive.
