symbol paying extra care to where you will see the Warning and Caution pointers.
4.2 Follow all safety instructions
Using this manual, read all safety instructions, messages and be
aware of the meanings of all safety decals. Ensure, if safety decals
are damaged or missing due to wear and tear or due to component
replacement, that they be replaced. Use the Decals section in the
provided spare parts book as a handy reference for spare part
codes and relevant decals, which are available from your McHale
dealer.
As with all machinery, learn all operations and use of controls by reading this
manual thoroughly. Do not attempt to let anyone operate this machine without
being fully instructed.
4.3 Store all items carefully

McHale Fusion 2 generic safety section
04-2
4.5 In case of emergencies
In the event of any accident, emergency
equipment should be kept close at hand. A first
aid kit and fire extinguisher along with emergency
phone numbers should always be available to
machine operators.
4.6 Stay clear of rotating elements
Serious injury or death can result from entanglement of clothing or body parts with
PTO shafts, drivelines and other rotating and moving components.
Keep all guards in place at all times, only wear close fitting clothing and ensure that
tractor engine has stopped, key removed and that PTO has stopped turning
before carrying out any adjustments, connections or cleaning of PTO driven
equipment.
4.7 Operating the McHale Fusion 2 safely
In order to avoid serious injury or even death by being pulled into the machine:
1. Never attempt to feed net or crop into the baling chamber or attempt to unplug
pick-up area while the baler is running.
2. Disengage PTO, shut tractor engine off and remove the key.
3. Stand well clear of baler and tractor when machine is operating.
4.8 In the event of a fire
In the event of a fire, the following is only given as a guideline procedure,
as it is the operators decision to ascertain the seriousness and hence the
solution to the situation.
1. Switch control box to manual mode (see section on Electronic control system).
Immediately tip bale off rear roller, leave roller in tipped position.
2. Eject bale from baling chamber by opening chamber doors.
3. Move tractor and baler away from the flammable material.
4. Disengage PTO, turn off tractor and remove key. Remove all hosing and
electrical looms from the machine.
5. With all connections removed, disengage drawbar from tractor. Drive tractor
away from baler.
6. Using a suitable fire extinguisher put out all fires.
Note: It is recommended that the baler be kept reasonably clean and free of
build-ups of grass, lubricants etc., this will help to reduce the risk of fires.
