PARTS TO INSPECT
In a FREQUENT INSPECTION, check for:
•
Piston wear
•
Signs of corrosion
•
Wear or damage to the cylinder or pump
•
Cracks, dents or any other damage to the frame, cylinder attachments, work table and its supports
•
Oil leaks
•
Loose or damage screws or joints
•
Damaged or incorrectly assembled accessories
In a PERIODIC INSPECTION, check for the same problems as in a frequent inspection but in addition, the hydraulic equipment should be disassembled and cleaned
by an authorized service dealer so that it may be examined internally.
Periodically clean and relubricate the press’s moving parts, such as the piston, winch, pumping mechanism, etc. This is especially important when working in salty or
humid environments.
Hydraulics equipment, which is subject to the very severe environmental conditions mentioned, previously should be cleaned and relubricated after each use.
To clean the hydraulic equipment, begin by removing the pump’s oil reservoir plug and draining al the oil. Fill reservoir with kerosene and thoroughly circulate it
thorough the hydraulic equipment. After completely purging the kerosene out of the hydraulic circuit, align the pump vertically with the head down and fill the
reservoir with the new hydraulic oil until the oil level rises to the orifice
USE ONLY LARZEP HYDRAULIC OIL

Always use the original LARZEP parts to prolong the service life of your hydraulic equipment.
LARZEP S.A
. or your authorized dealer can supply you with original
parts for simple maintenance work.
