Pistons are not compressing
The pistons on the Lifetime Mammoth 90964 may not compress due to one or more of the following causes:
- The system may not be fully assembled or assembled incorrectly.
- There could be damage or obstruction in the piston or adjustment mechanism.
- Rust or debris may be present, preventing movement.
- The adjustment handle may not be firmly grasped or released properly.
- Missing or incorrectly installed hardware (e.g., bolts, washers) could block piston movement.
Inspect the assembly and mechanism, ensure all parts are installed correctly, and check for rust or damage.
