Assembly & Installation

Unpack and inspect all components. Assemble on a flat, stable surface.

Attach hydraulic cylinder: Secure to frame using provided bolts and wrench.
Install bending dies: Select appropriate die for pipe size, lock into position.
Connect hydraulic pump: Attach hoses to cylinder, ensure tight connections.
Fill hydraulic oil: Use recommended hydraulic fluid, check level.
Test operation: Perform dry run without pipe to ensure smooth movement.

WARNING! Tool is heavy; use proper lifting techniques. Ensure all bolts are tightened securely.

First-Time Setup

Prepare bender for initial use following these steps.

Select correct die: Match die to pipe diameter being bent.
Position pipe: Insert pipe fully into die, align with bending mark.
Set bending angle: Use angle gauge or reference marks on die.
Apply hydraulic pressure: Pump lever slowly to begin bending.
Check angle: Use protractor to verify accuracy, adjust as needed.

CAUTION! Wear safety glasses and gloves. Keep hands clear of moving parts.

Controls and Components

Main components: Frame, hydraulic cylinder, pump lever, pressure gauge, release valve, dies.

Controls: Pump lever (apply pressure), Release valve (return cylinder), Pressure gauge (monitor force).

Operation: Position pipe, pump lever to bend, open release valve to retract. Adjustment: Use different dies for pipe sizes; adjust bending angle with stop pins. Safety: Pressure relief valve prevents overload; secure all connections before use.

Operation Procedure

Step-by-step bending process for accurate results.

Select die matching pipe diameter.
Insert pipe into die, align bending point with die center.
Secure pipe with clamp if provided.
Pump lever slowly to apply hydraulic pressure.
Monitor pressure gauge; do not exceed recommended PSI.
Stop pumping when desired angle is reached.
Open release valve slowly to retract cylinder.
Remove bent pipe from die.

Tip: Practice on scrap pipe first. Mark bending points clearly.

Bending Techniques

Methods for different bending requirements.

Standard bend: Single angle bend (90° most common).
Multiple bends: Measure and mark each bend separately.
Offset bends: Calculate offset distance for parallel pipes.
Springback allowance: Over-bend slightly (2-3°) to account for material springback.
Tube bending: Use appropriate dies for tubing; support to prevent flattening.
Consistent pressure: Maintain steady pumping speed for smooth bends.
Angle verification: Use angle finder or template to check accuracy.
Record settings: Note pressure and position for repeat bends.

WARNING! Do not exceed rated capacity. Use only recommended dies.

Safety Features

Pressure relief valve: Automatically releases at maximum pressure. Secure locking: Dies lock firmly in place. Stable base: Prevents tipping during operation.

Maintenance & Cleaning

Regular maintenance ensures optimal performance and longevity.

After each use: Clean dies and frame with dry cloth.
Weekly: Check hydraulic oil level, top up if needed.
Monthly: Inspect hoses for leaks or damage.
Quarterly: Lubricate moving parts with light machine oil.
Annually: Replace hydraulic fluid; inspect all components.

CAUTION! Never use water or solvents on hydraulic components. Store in dry location.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Cylinder won't extend	Low hydraulic oil	Check oil level; refill to recommended level.
Cylinder won't retract	Release valve closed	Open release valve fully; check for obstruction.
Leaking hydraulic fluid	Loose fittings or damaged seals	Tighten connections; replace seals if necessary.
Pipe slipping in die	Wrong die size or worn die	Use correct die; inspect for wear.
Inaccurate bends	Improper alignment or marking	Realign pipe; use precise measurement.
Excessive force required	Pipe material too hard or thick	Check pipe specifications; do not exceed capacity.
