Operation
Operation Warnings

Never drive the tractor with arm out-stretched (except when cutting). When
moving from work always first retract arms. Transport with care, metal fatigue
is always caused by careless transportation and misuse. If the ground is
uneven or bumpy,
slow down.

Read this manual and be fully familiar with all operational maintenance and
safety procedures.

Practice in open space without rotor running until familiar with controls. Take
care working the head close to the tractor as it may be possible to strike
the tractor

Remember one of the clever features of the Twiga range is its ability to
operate within a very narrow space, often within the tractor’s width. This will
mean it is quite possible for the flail head to foul the tractor. When in confined
space the main arm will need to be slightly slewed backwards from normal
working position. Practice all these positions and be very familiar with your
machine before ever attempting work.

Never operate above the recommended PTO speed of 540 R.P.M. Failure to
heed this warning will result in severe damage i.e. reduced belt and pulley life
(when fitted);
greatly increased oil temperature ; risk of rotor going out of
balance, as well as reduced machine life, and may cause expensive repairs.

Failure to start and stop the rotor at a low PTO speed or to operate at the
correct speed will result very quickly in severe motor and/or pump damage.

Never attempt to slew arms when fully out stretched - always retract before
operating the slew. Be very careful when operating on sloping ground.

Never attempt to slew arms with the head on the ground, always raise the
head before slewing.

Never attempt to operate the machine while going backwards. It will
immediately damage the arms and possibly the flail head. Remember, before
selecting reverse gear always lift the flail head out of work and retract the
arms towards the tractor.

Never change/reverse the rotor rotation until it has come to a standstill,
serious damage will occur leading to premature pump and/or motor failure.
