Hydraulic Connections - Chicago Pneumatic Titan LP series Operator's Manual

Drive Direction
The direction the drive rotates in the LP‐tool is determined by its orientation on the application. Refer to Figures 7 & 8 for drive directions based on right‐hand threads.
Reaction
• Every Titan LP‐Series torque wrench is designed to react off the link. See Figure 8 for location of the reaction area.
• Ensure this area is abutted to a strong stationary object during operation.
• DO NOT ATTEMPT TO REACT ON AN AREA OTHER THAN INDICATED IN FIGURE 8.
• THIS CAN CAUSE SERIOUS INJURY OR DEATH TO THE OPERATOR AND DAMAGE TO THE TOOL OR APPLICATION.
• CONTACT TITAN IF A CUSTOM REACTION PAD OR EXTENDED ARM IS REQUIRED.
Determining the Pump Pressure
The torque of your Titan LP‐Tool is controlled via the pressure of the pump. Every Titan tool comes with a pressure to torque calibration chart that will help you determine
the pump pressure settings for your torque requirements.
• Refer to the torque requirements of the plant or equipment manufacturer before beginning the job.
• 1. Locate the torque chart for your tool serial number and find the closest torque to your requirements.
Adjusting the Pump Pressure
To set the pressure on your Titan Pump follow this procedure:
• Make these adjustments BEFORE putting torque wrench on nut or bolt head.
A) See torque wrench chart to have the amount of pressure required to produce desired torque.
B) Press and hold the white button to advance the piston.
C) While holding the button, slowly turn the pressure valve (clockwise) to increase pressure on the gauge.
D) Stop when the required pressure appears on the gauge and release the button.
E) Repeat A to see the pressure on the gauge.
F) If the pressure on the gauge is not correct, repeat step B to D
• Once the desired pressure has been reached tighten the lock nut on the pressure control valve.
• You can put the tool on the nut and run the pump.
Setup to Tighten Fasteners
1. Once you have set your target pressure, cycle the tool several times without load to ensure the system is operating properly and any air is out of the lines.
2. Place the tool on the nut in the direction for tightening (see figure 7 & 8).
3. Place the reaction area against a strong, stationary object (i.e.) an adjacent nut, flange, or equipment housing.
NEVER HOLD THE TOOL DURING OPERATION
4. Be sure all body parts are out of harm's way.
5. Make sure all hoses and electric cords are clear of obstructions and the tool.
6. Apply momentary pressure to ensure that the tool is properly placed and does not "ride up" or move on the application.
Operation
1. Depress the white button on the remote control. The tool will spin slightly about the ratchet until the link contacts the reaction point.
2. Continue to hold down the advance button as the ratchet turns. You will hear several audible "clicks" of the reaction pawl as the ratchet turns. When these "clicks" stop,
the piston is at the end of the stroke and pressure will increase rapidly.
Note: The reading of the preset pressure after the piston is extended DOES NOT indicate the set torque is applied to the bolt. This only indicates that the piston is fully extended
and cannot turn the socket further.
3. Release the white button on the remote control and the piston will retract. The tool will automatically reset itself and the operator will hear another set of "clicks". When
these "clicks" stop, the piston is fully retracted and another cycle can begin.
4. Repeat steps 1‐3 until the tool stalls.
5. To verify the set torque is reached, release the advance button and allow the piston to retract. Depress the advance button again, if the tool stalls and the pump
pressure increases to the set pressure, the desired torque has been reached.
Note: Occasionally the tool will lock on the application and become difficult to remove. This usually happens when applying torque to long fasteners. To release the tool from the
fastener:
1. Depress the advance button on the control pendant.
2. Flip reaction pawl lever toward reaction arm and hold in position.
Note: If the reaction lever does not move, increasing the pump pressure slightly may help.
3. Release the advance button and allow the piston to retract. The tool should be free and it can be removed from the application
Removing Fasteners
To remove fasteners, follow these steps:
1. Place the tool on the nut in the desired direction to loosen the fastener (see Figures 7 & 8).
2. Set the pump to pressure to 700 Bar (10 000 psi).
3. Place the reaction portion of the link against a strong, immovable surface.
4. Press and hold the advance button. The ratchet should begin to turn.
5. Cycle the tool until the fastener can be removed by hand.
More torque is required to remove a fastener than to tighten it. If the tool was near maximum capacity during fastening, a larger tool may be required to remove the fastener.
5. TOOL CARE AND MAINTENANCE
1. Clean all dirt and grit from the link
If tool is used in an underwater situation, especially sub‐sea, remove all water. Dry and grease tool before storage.
2. Inspect the ratchet, link, and housing for cracks and other signs of wear. If one is present, discontinue use and contact Titan for a replacement part.
3. Store tool in a clean, dry area.
• Following these simple procedures can extend the service life of your tool.
• RE‐calibrate your tool periodically. Over time, internal components wear and can bring the tool out of calibration. Titan recommends a 6‐12 month calibration
cycle. Your work may require a different calibration cycle, check with your manager for this cycle.
• Periodically clean and lubricate internal parts in the tool with Dow Corning GN Metal paste.

Hydraulic Connections

1. Unplug the power cord and open all hydraulic controls to ensure that the tool is not pressurized. Make sure the gauge reads 0 (zero) to assure pressure has been
released.
2. Never disconnect the hoses without first releasing the pressure from the system.
3. Screw the coupler to the nipple and tighten by hand.
Bleeding Air from the System
Air may accumulate in the hydraulic system if the reservoir oil level is too low. This causes the wrench to respond in an unstable or slow manner. To remove air from
system:
1. Plug in the pressure return line into the pump and connect the other side of the hose to the male‐female quick connect.
