Particular Notes
1. The energy unit is of S3 duty, which can only be worked intermittently,i.e. 1minute on and 9 minutes off.
2. Clean all of the hydraulic parts concerned before installation of the energy unit.
3. Viscosity in the hydraulic oil shoud be 15~46 cst, which ought to also be clean and absolutely free of impurities, N46 hydraulic oil is recommended .
four. Check the oil degree within the tank right after the first operation from the energy unit.
five. Oil transforming is required soon after the preliminary 100 operation hrs, afterwards the moment just about every 3000 hours.

General Description
This energy unit is deigned for those dock levellers which need to have floating ramps with an emergency halt perform. The ramp will rise when the pump is working.The lip will expend automatically once the ramp cylinder finishes its stroke. The ramp cylinder will retract when the pump stops running. An emergency stop will probably be recognized though the solenoid valve is energized. The lowering speed of both the ramp plus the lip is adjusted from the needle valves within the method.

General Description
This Dock leveler power unit simply raised the ramp when the motor is activated, once the ramp has reached total extension the sequence shifts to lengthen the lip. The ramp and lip are lowered by separate solenoid valves even though the descent. Both the ramp and lip f of every functions are controlled by a needle valve. The needle valves are adjustable to achieve the desired descent speed of each function. The 2nd relief valve guarantees the primary platform to become floating under load when the dock leveler is being used for loading and unloading the goods, therefore defending the dock leveler successfully.
