16 MOVING THE MACHINE
The tire changer has got a fork (1, Fig. A) which has been positionned there on purpose for moving the machine.
Follow these instructions:
1) Lower the clampingchuck arm (2, Fig. A) completely down.
2) Close completely the jaws of the chuck (3, Fig. A).
3) Bring the sliding ramp (4, Fig. A) at the end of its travel, near the arm.
4) Insert into the lifting fork a hoisting belt (at least 2,5 inches (60 mm) wide and of a lenght sufficient to bring the hook of the belt above
the tire changer).
5) With the special belt ring bring the 2 ends of the belt together and lift with a sufficiently strong lifting truck.
If the machine has to be stored for a long time (3-4 months) you have to:
1) Close the jaws of the chuck; lower the clamping chuck arm down; lower the tool holding arm down, into the working position.
2) Disconnect the machine from all power sources.
3) Grease all the parts that could be damaged if they dry out:
- the chuck
- the slot of the tool holding arm
- the slides of the carriage
- the tool
Empty oil/hidraulic fluid reservoirs and wrap the machine in a sheet of protective plastic to prevent dust from reaching the internal
working parts.
If the machine has to start working again after a long storing period, it is necessary to:
- put the oil into the reservoirs again.
- restore the electric connection.
