Regular maintenance ensures the longevity and safe operation of your floor jack.

• تشحيم: Periodically lubricate all moving parts, including the pivot points and casters, with light machine oil.
• السائل الهيدروليكي: Check the hydraulic fluid level regularly. If low, add high-quality hydraulic jack oil. Do not use brake fluid or other non-approved fluids.

• Release Valve Threads: If the release valve becomes stiff or causes the jack to lower too quickly, apply a small amount of oil to the threads of the release valve mechanism. This can help ensure a smooth and controlled lowering action.
• تخزين: Store the jack in a clean, dry place with the ram fully retracted to prevent corrosion and extend seal life.
