DYF split type hydraulic puller use method

1. When using, put the slotted end of the handle into the return valve stem and tighten the return valve stem clockwise.

2. Adjust the hook jaws to the hooks to catch the pulled object.

3. The handle is inserted into the tilt hole to tilt the piston's starting lever forward and forward smoothly, and the claw hook retreats accordingly to pull the pulled object.

4, the hydraulic puller piston start lever effective distance is only 50mm, so use when the reach should not be greater than 50mm, when not pulled out to stop, release the oil return valve, let the piston start rod retracted, adjusted after a second time Repeat steps 1, 2, and 3 until they are pulled out.

5. To retract the piston starting rod, just use the handle slotted end to loosen the return valve stem counterclockwise, and the piston starting rod gradually retracts under the action of the spring.

6. Before use, according to the outer diameter of the object to be pulled, pull distance and load force, select the corresponding tonnage of the hydraulic puller, avoid overloading and avoid damage.

7. The hydraulic puller is used in -5°C~45°C, and uses (GB443-84)N15 mechanical oil; it is used in -20°C~-5°C and adopts (GB442-64) synthetic spindle oil.

8, in order to prevent damage caused by overloading equipment, hydraulic devices equipped with overloaded automatic unloading valve, when the object is pulled over the rated load, the overload valve will automatically unload, should be used to select larger tonnage hydraulic puller.

Jining Union Machinery And Parts Co.,Ltd is very professional in doing cylinders for Excavator. The arm cylinder, bucket cylinder and boom cylinder are for all brands of excavators.

We use the cold draw seamless steel tubes with strong honing technique.Length of the cylinder can reach up to 3m with diameter from Ã˜40~Ø400.The piston rods are made of 40Cr with treatment of quality adjustment followed by high frequency quenching and then hard chrome plating,which makes it flexible inside and hard outside with high smooth surface.The piston rod's adopt quality NOK seals and diameters are from Ã˜5~Ø140.The quality of our cylinder is ensured by high-pressure test bed.   And we have successfully passed ISO 9001: 2000 in aspect of our production and sales of our hydraulic fittings. We also can supply the cylinder parts to our customers such as the:       cylinders,rodpistons,cylinders,headcylinders,plungers,nuts,etc.
