1、 General description.

In order to avoid polluting the hydraulic oil, before filling the hydraulic oil tank, please clean the dirt around the funnel and oil port to prevent dust or even sand particles from mixing into the oil tank. Do not raise the oil level line of the oil tank oil level gauge to avoid hydraulic oil overflow.

► Please replace or filter the hydraulic oil in time after the new car has been lifted 300 times.

Lubricate all rotating points regularly to reduce wear and extend service life.

► Regularly check whether the fastening bolts of the upper and lower supports of the oil cylinder are loose.

► Regularly check whether the fixed parts on the amplifier stand are loose or falling off.

skill:

It is dangerous to carry out maintenance near or rotating parts. Double output shaft cycloidal motor If it is necessary to lift the trunk during maintenance, please ensure that the trunk is safely supported. If you work on or under the trunk that is not safely supported, life will be endangered.

The second is the selection of hydraulic oil.

To avoid damage to the hydraulic cylinder, we recommend the viscosity of the hydraulic oil (40 º С 75-16mm ²/ S. Oil temperature shall not exceed 80 º С。

At - 10 º С- 40º С L-HM anti-wear hydraulic oil, 46 # in summer and 32 # in winter, is recommended under the ambient temperature of.

In summer, the ambient temperature is greater than 40 º С L-HM68 anti-wear hydraulic oil is recommended to be used in.

At - 30 º С L-HV32 low temperature hydraulic oil is recommended for the above ambient temperatures.

At - 30 º С L-HS32 low-temperature hydraulic oil is recommended for the following ambient temperatures.

Suggestion: When the oil temperature is higher than 65 ℃, BM-D cycloidal motor Hydraulic cooler shall be used to avoid overheating; Hydraulic oil cannot be mixed at low temperature.

3、 Maintenance.

In order to save maintenance costs, reduce downtime, and extend the service life of hydraulic products, daily visual inspection is very necessary.

The parts inspected every day are:

Lift the empty car and check whether the oil cylinder and the mast tilt to both sides.

2、 Check the position of hydraulic oil level, Variable cycloid motor Observe the oil drops under the vehicle and the hydraulic cylinder for leakage.

Check the matching, rotating position and installation of oil cylinder, amplifier and upper and lower supports.

4、 Check whether the large nuts on each support of the oil cylinder and the front top cylinder are loose, and whether the clearance between each support of the oil cylinder is reasonable.

Check the lubrication condition of oil cylinder, amplifier, upper and lower support rotating points, and refill lubricating oil in time.

6. Check the wear of the composite bushing at each turning point and replace it in time.

Note: It is very dangerous for the tilt mechanism to tilt to both sides, which will also cause the fastening bolts on the upper and lower supports of the oil cylinder to loosen, resulting in serious damage, or even overturning.
