Torque Converter Type:

Hydrodynamic torque converter providing automatic gear shifting and smooth engagement.

Transmission Fluid Capacity:

Approximate capacity of 9-12 liters (check manual for exact specification and type).

Transmission Fluid Part Number:

Consult manual or dealer for specific Mitsubishi part numbers. Generic equivalents like CAT TO-4 fluid or Dexron III are often suitable.

📐 Dimensions

Exterior:

Overall length, width, and height vary based on mast configuration and tire type, but typical dimensions are around 2.5-3m length (without forks), 1.2-1.5m width, and 2-2.5m height (traveling mast).

Interior:

Operator compartment designed for comfort and visibility, with adjustable seat, ergonomic controls, and clear instrument panel.

Cargo:

Standard fork length approximately 1.2m (48 inches), with adjustable fork spread. Lifting height typically ranges from 3m to 6m+ depending on mast type.

Weights:
