Setup
Before operation, ensure the puller is correctly assembled for your specific task. The puller can be configured with either two or three jaws.
- Select Jaw Configuration: Determine if a two-jaw or three-jaw setup is suitable for the item to be pulled.
- Attach Jaws: Install the selected jaws onto the leg puller yoke. For a three-jaw setup, fix the claws at positions 1, 2, and 3 of the claw plate. For a two-jaw setup, fix the claws at positions 'a' and 'b' of the claw plate.
- Secure Jaws: Rotate the jaws clockwise along the threads to secure them.
- Mounting Claw: Ensure the mounting claw is properly engaged with the workpiece.
- Adjust Nut: Adjust the nut until it is snug but allows for movement.
- Mount Handle: Attach the operating handle to the hydraulic pump.

Operating Instructions
The hydraulic gear puller is designed for pulling hubs, flanges, gears, pulleys, flywheels, and bearings. It can be operated horizontally or vertically.
- Position the Puller: Place the puller so that the jaws securely grip the component to be removed. Ensure the center screw is aligned with the shaft.
- Tighten Oil Return Switch: Locate the oil return switch on the hydraulic pump and tighten it clockwise to close the valve.
- Operate Handle: Pump the operating handle to build hydraulic pressure. The pressure will extend the ram, pushing the component off the shaft.
- Monitor Progress: Continue pumping until the component is safely removed. Avoid excessive force.
- Release Pressure: Once the component is removed, slowly turn the oil return switch counter-clockwise to release the hydraulic pressure and retract the ram.
- Remove Puller: Carefully remove the puller from the workpiece.

Maintenance
- Cleaning: After each use, clean the puller components to remove dirt, grease, and debris.
- Lubrication: Periodically apply a light coat of oil to the threaded parts and moving joints to prevent rust and ensure smooth operation.
- Inspection: Regularly inspect the jaws, ram, and hydraulic cylinder for signs of wear, cracks, or damage. Replace any worn or damaged parts immediately.
- Hydraulic Fluid: Check the hydraulic fluid level periodically. If low, refill with appropriate hydraulic oil. Consult a qualified technician if you suspect a leak.
- Storage: Store the puller in its original case or a dry, secure location to protect it from environmental elements and prevent damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Puller not generating force | Oil return switch open; Low hydraulic fluid; Air in system | Ensure oil return switch is fully closed; Check and refill hydraulic fluid; Bleed air from the system (consult technician if unsure) |
| Ram not retracting | Oil return switch not fully open; Obstruction | Ensure oil return switch is fully open; Check for any physical obstructions preventing retraction |
| Jaws slipping | Improper jaw engagement; Worn jaws; Workpiece surface too smooth | Re-position jaws for better grip; Replace worn jaws; Use a suitable gripping aid if necessary |
| Oil leakage | Damaged seals; Loose connections | Inspect seals and connections; Tighten loose connections; Replace damaged seals (professional service recommended) |
