parts in accordance with local regulations.
3.11 Both the repair kit, which exclusively contains the retainers and the spare part sets must be ordered using the reference
assigned in the table.
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. Dismantle the hydraulic unit and with the piston fully retracted, remove the ller plug and
drain its contents into a container. With the hydraulic in a horizontal position, proceed to introduce the necessary volume for
each model as indicated in these instructions. Avoid the entrance of any dirt with the new oil.
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.
CAUTION: In order to prevent possible accidents, all inspections, maintenance and repairs must be carried out
when it is not loaded, when it is not in operation.
