B4 - TENSION AND ALIGNMENT OF THE MAST LIFTING CHAINS
CHECK - ADJUST
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’s chain fasteners and
the chain rollers.
- Manually verify the chain tension, if necessary adjust as following while ensuring that the
carriage is perpendicular to the mast.
- Untighten the nut 1 (fig. B4).
- Untighten the lock nut 2 (fig. B4) of the chain tension adjuster.
- Adjust the tension by tightening or untightening the nut 3 (fig. B4) while checking the
alignment of the lifting chains.
- Then block the lock nut 2 (fig. B4) and the nut 3 (fig. B4).
- Retighten the nut 1 (fig. B4).
These checks are important for the good working operation of the mast. In case of technical faults, consult your dealer.
B5 - MAST
GREASE
To be carried out weekly, if the lift truck has been operated for less than 50 hours during

Clean and lubricate the following points with grease (see : 3 - MAINTENANCE : LUBRICANTS
AND FUEL) and remove the surplus of grease.
1 - Lubricators of the articulation axles at the foot of the mast (2 lubricators) (fig.
