10.10.2 Check the trip arm safety switch operation
1. Ensure that the tractor is stopped, handbrake applied, engine stopped and
ignition key removed.
2. Push only one of the trip arms into the tripped position.
3. Ensure that all persons are well clear of the machine. Start up machine, go to
manual mode and try to operate the dispenser.
4. There must be no dispenser movement.
5. Turn off the machine and tractor and repeat the procedure for the second
dispenser.
10.10.3 Check that wrapping arm does not exceed 30 rpm
See section 12.4 to adjust.
10.10.4 Check the wrapping arm stopping performance
1. In manual mode, run the wrapper at full speed (i.e. press the rotation button
twice) with two new film rolls fitted on the dispenser.
2. Upon releasing the rotation switch, the arm rotation should stop immediately.
If there is run-on, do not operate the machine. Contact your McHale dealer for
assistance.
10.11 Chain adjustments
It is important for the efficient operation of the
machine that all drive chains are kept correctly
tensioned. The following is a general guide to chain
adjustment.
The sag is measured at the midpoint of the chain
between the sprockets. Always ensure one side of
the chain is tight so that the correct reading is
obtained. Even though some drives differ in detail
the basic adjustments stay the same.
WARNING: There must be no dispenser movement while an arm is
tripped
If there is any dispenser movement while an arm is tripped there is a
serious safety issue with the switch. Do not operate the machine.
Contact a McHale authorised dealer for further assistance.
WARNING: Dispenser arm rotation speed must not exceed 30 rpm
The dispenser must never be operated above a maximum of 30 rpm
otherwise the dispenser arm kinetic energy is above what the trip arm
design is capable of stopping in an emergency situation.
