IMPORTANT: The biggest problem that causes product failure is dirt. Keep it clean and well lubricated to prevent any foreign
body from entering the hydraulic circuit. If you have been exposed to rain, snow and/or sand you must clean it before use.
1. Store in a well-protected area where it is not exposed to corrosive vapours, abrasive dust, or other harmful elements.
2. Lubricate moving parts regularly.
3. Change the oil at least once a year. The pistons should be fully retracted prior to proceeding to check or refill the oil level. The oil
level is correct when it is between the two marks on the rod. Refill as required in accordance with the volume indicated in the table.
IMPORTANT: The use of alcohol or brake fluid can damage the seals and cause the product to fail.
4. Check the product before each use. Take appropriate action if you see any of these occurrences:
a. Damaged hose
b. Damaged structure
5. Keep warning labels and instructions clean and legible. Clean outer parts with mild soap.
Repairs must be carried out in a clean environment by qualified personnel who, through their training and experience, are familiar
with the hydraulic systems used in these appliances.
