  • Overview

Introduction

Zero-leakage double-check solenoid valves separate the two independent hydraulic circuits for the main and auxiliary platforms of a double-scissor lift. Two shut-off valves allow manual lowering in the event of a power failure. Additional solenoid valves can be fitted to provide more independent circuits for the corresponding cylinders.

Precautions

  1. S3 intermittent duty: 1 minute on and 9 minutes off. Continuous operation is not permitted.
  2. Clean all hydraulic components, cylinders, hoses and fittings before installing the power unit.
  3. Use clean hydraulic oil free of impurities, with a viscosity of 15-68 cSt. N46 hydraulic oil is recommended.
  4. Mount the power unit vertically.
  5. Check the oil level in the tank after the initial operation of the power unit.
  6. Change the hydraulic oil after the first 100 operating hours and every 3,000 hours thereafter.
