WARNING
When disconnecting the lift chains, keep control
of the ends. Use wire to temporarily connect the
ends of the lift chains to the mast. This procedure
will prevent the lift chains from falling and caus-
ing an injury or damage.
1.
Remove chain pin from each chain anchor at
the carriage. Disconnect lift chains from car-
riage. Use wire to connect the ends of lift chains
to a part of the mast. Make sure chains can
move freely when inner mast is raised. See Fig-
ure 10.
WARNING
To help prevent possible injury, make sure the
carriage is stable and will not fall over when the
inner mast is raised above the load rollers of the
carriage.
2.
Use lift cylinders to raise inner mast. If hy-
draulic system cannot be used, disconnect lift
cylinders from inner mast. See the Cylinder
Repair manual listed in the General section of
this manual for procedures.
3.
Connect a crane with a capacity of at least
700 kg (1550 lb), to top of inner mast. Carefully
raise inner mast until it is above the load roll-
ers of the carriage. Install safety chains to se-
cure mast in its extended position and discon-
nect the crane. See Safety Procedures When
Working Near Mast.

Move lift truck away from carriage. Completely
lower inner mast so it cannot move.
