If the mast lifts crooked or leans to one side:
- Check the lift chains – one side may be looser than the other
- Inspect the mast rails – look for damage or wear
- Check the lift cylinders – one cylinder may be weak or leaking
- Look at the carriage rollers – worn rollers can cause uneven lifting
Solution:
Adjust the chain tension so both sides are equal. If a cylinder is leaking, replace the seals or the cylinder. For worn rails or rollers, replacement is needed. If you are not sure, call a forklift mechanic.
