2. PRODUCT DESCRIPTION
This product is designed to lift, position, or move, but not sustain, rated capacity loads. It is not
designed to be used as a stand-alone device. Any load lifted, positioned, or otherwise moved by
this device, must immediately be supported by appropriately rated mechanical means. A wide
variety of applications exist for this category of product. Special skill, knowledge and training may
be required for a specific task and this product may not

1.
Before operating, estimate the weight of the load. Do not overload the jack beyond its rated load.
2.
Select point of action according to the gravitational center place the jack on the hard ground if
necessary. Place a hard plank under the jack to avoid tottering or galling during operation.
3.
Before operating the jacks. First, insert the notched end of the handle into the release valve. Turn
the operating handle clockwise until release valve is closed. Do not over tighten the valve.
4.
Insert the operating handle into the socket and the ram until it is steadily raised by the up and
down movement of the handle and the load is raised. The ram will stop rising when the required
height is reached.
5.
Lower the ram by turning the release valve counterclockwise with the notched end slacken it
slowly when a load is applied, or accidents can occur.
6.
When more than one jack is used at the same time, it is important to operate the different jacks at
an equal speed with equal load. Otherwise, there is danger of falling the entire fixture.
7.
At an ambient temperature from -2° C (27° F) to 45° C (113° F) use machine oil (GB443-84) N15. At
an ambient temperature from -20° C (-4° F) to -2° C (27° F) use synthetic spindle oil (GB442-64).
Sufficient filtered hydraulic oil should be maintained in the jacks. Otherwise, the rated height cannot
be reached.
8.
Violent shocks must be avoided during the operation.
9.
User must operate the jack correctly according to operating instructions: if the jack has some
quality problems, it cannot be used.
