Notice
– Examine motor and solenoid valve wiring, virtual earth is prohibited.
– When install for the first time, notice inner oil in the oil tank, add enough oil after one working
cycle
– When wiring motor and solenoid valve, notice the power voltage is in accordance with the
marked one. AC motor shell should ground reliably and never run un-grounded. Prevent water
and humidity to motor connection box. When connect for the first time, start motor and check
motor direction, it rotates in counterclockwise seen from the rear motor. It is strictly prohibited
motor reverse rotation and no oil rotation.
– When add oil, hydraulic oil must be filtered and the filter fineness is no lower than 25µm.
– Power unit cannot filter out the impurity in the inner cylinder, so the inner cylinder should keep
clean to avoid control valve invalid. Pipeline should also be clean.
Maintenance
– Keep clean on the element and the pipeline, avoid dirty go into the system.
– Keep the oil level in the oil tank, add oil after certain working cycle. If pump absorbs air, it may
damage the pump and the sealer.
– Replace new oil after truck adds hydraulic oil for the first time and travel 100 hours. And then
replace new oil every year(about 1500hrs).
– Hydraulic oil viscosity is 22～46mm
2
/s.
– Working temperature with high temperature needs oil with high viscosity and low temperature
needs oil with low viscosity
