Introduction

This document provides detailed instructions for the safe and effective use of hydraulic pipe bending machines. These machines are designed for precise bending of pipes and tubes, featuring a robust construction and user-friendly operation.

Construction and Components

The machine comprises several key components, including a ram pump, cylinder seat, handle, tube-bending mould, and fuel tank. Understanding the function of each part is crucial for proper operation and maintenance.

Technical Specifications

The series of bending machines includes models such as SWG-2A, SWG-3B, and SWG-4D, each with varying working pressures, capacities, and fuel tank volumes. Refer to the technical index for specific details on each model's capabilities.

Operating Instructions

Follow these steps for correct operation: tighten the switch, grease contact points, select the appropriate mould based on tube size, and use the fast and slow pump mechanisms to achieve the desired bend. Ensure proper placement of supporting wheels to prevent damage.

Maintenance and Troubleshooting
