Installation & Setup

Unpack and inspect all components. Mount on stable surface.

  1. Secure bender: Use mounting brackets to attach to sturdy workbench or floor.
  2. Install dies: Select appropriate die for tube diameter; secure per instructions.
  3. Connect hydraulic pump (if applicable): Attach hoses securely; fill with hydraulic fluid.
  4. Check all fasteners: Ensure bolts and nuts are tight.

WARNING! Bender is heavy; use proper lifting techniques. Ensure mounting surface is level and secure.

First-Time Use

Prepare bender for initial operation.

  1. Lubricate: Apply recommended lubricant to moving parts and die surfaces.
  2. Test operation: Perform dry run without tube to ensure smooth movement.
  3. Select tube: Use appropriate material and diameter for selected die.
  4. Make test bend: Use scrap material to verify angle and die setup.

CAUTION! Wear safety glasses and gloves. Keep hands clear of pinch points.

Specifications

Controls and Components

Main components: Frame, bending die, ram, pump/lever, angle gauge, pressure release.

Operation: Insert tube, set desired angle, operate pump/lever, release pressure, remove tube.

Adjustments: Angle stops, die positioning, pressure settings (if hydraulic). Safety: Lockout mechanism, pressure relief, emergency release. Maintenance: Lubrication points, hydraulic fluid check, bolt tightening schedule.

Bending Operations

Step-by-step bending procedure.

  1. Select die: Choose die matching tube diameter.
  2. Insert tube: Place tube against die and support.
  3. Set angle: Adjust angle gauge or stops to desired bend.
  4. Apply pressure: Operate pump or lever slowly and steadily.
  5. Monitor bend: Watch angle indicator; stop at desired angle.
  6. Release pressure: Use release valve to retract ram.
  7. Remove tube: Carefully extract bent tube from die.

Tip: For consistent bends, mark tube at bend point and use slow, even pressure.

Die Selection & Setup

Proper die selection ensures quality bends.

  1. Match diameter: Die must match tube outer diameter exactly.
  2. Check material: Different dies for different materials (steel, aluminum, copper).
  3. Secure die: Tighten all fasteners; ensure die is centered.
  4. Test fit: Tube should slide into die without force.
  5. Lubricate: Apply lubricant to die groove for smooth operation.

WARNING! Using wrong die can damage tube or bender. Never force tube into die.

Safety Features

Pressure relief valve, safety lock, emergency release, overload protection.

Care & Maintenance

Regular maintenance ensures longevity and safety.

  1. Clean after use: Remove metal shavings and debris.
  2. Lubricate: Apply lubricant to moving parts weekly.
  3. Check hydraulic fluid: Maintain proper level (if applicable).
  4. Inspect dies: Look for wear or damage; replace as needed.
  5. Tighten fasteners: Check bolts and nuts monthly.

CAUTION! Never operate with damaged components. Store in dry location.
