Do not use the hoses for transporting the device. Use the handles on the cylinders (when appropriate) and set the pump lever to the transportation position. When filling the pump with oil, always use LARZEP hydraulic oil or another oil of similar characteristics. Fill only to the indicated level and remember that the cylinder piston should be back.

TECHNICAL FEATURES The “W” Hand Pumps are compact, light and portable used to power single acting-cylinders, they operate horizontally or vertically, with pump head downwards. All models with pressure relief valve. The two speeds pumps are recommended for applications where the cylinder plunger must move rapidly, also for larger cylinder hook-ups where greater oil capacity is required.
All double action LARZEP cylinders are equipped with a mechanical end of stroke capable of withstanding the nominal pressure. You can therefore carry out the test described in the previous section. If you are working with another type of cylinder and are not 100% sure, do not carry out this test.
