These checks are important for the good working operation of the mast.
In case of technical faults, consult your dealer
Place the lift truck on level ground with the mast in a vertical position and the forks
lifted at approximately 200 mm.
- Check the alignment of the mast lifting chains between the carriage chain fasteners
and the chain rollers.
- With your hand verify the chain tension and, if necessary, adjust as indicated below
while ensuring that the carriage is perpendicular to the mast.
- Loosen nut 1.
- Loosen the chain tensioner lock nut (2).
- Adjust the tension by tightening or loosening the nut 3 while checking the alignment of the lifting chains.
- Then tighten lock nut (2) and nut (3).
