HYDRAULIC RAM ASSEMBLY
1. Visual inspection must be made before each use of the crane, checking for cracks, cracked welds
and missing and/or damaged parts. Any crane that appears to be damaged in any way must be
removed from service immediately.
2. BECAUSE OF THE POTENTIAL HAZARDS ASSOCIATED WITH THE MISUSE OF EQUIPMENT
OF THIS TYPE, NO MODIFICATIONS SHALL BE MADE TO THE PRODUCT.
3. Store crane with boom in fully lowered position and hydraulic ram valve closed when not in use to
prevent machined surfaces from exposure. Keep all moving parts clean and well lubricated.
4. Replace worn or damaged parts with Performance Tool replacement parts. Be sure that only
qualified personnel perform repairs.
