▲
Always operate the machine at the recommended PTO speed. Never exceed the
maximum permitted.
▲
When the cutter head is swung to the side (working position) of the tractor, it exerts a
momentum on the tractor causing the tractor to rock from side-to-side. Extreme Care
should be taken when operating on slopes, Bodily Harm or Death could result from
tractor's tipping over.
▲
Never swing the arms of the machine over if the tractor is facing sideways, across or
facing down a slope. If swinging over on sloping ground is unavoidable the tractor must
always face directly up the slope.
▲
Never allow riders on the tractor. Never lift a person with the boom or cutterhead. KEEP
BYSTANDERS CLEAR.
▲
Inspect the entire machine periodically. Look for loose bolts, worn or broken parts,
pinched hydraulic hoses, and leaky or loose fittings. Make sure all pins are secure: Serious
injury may occur from not maintaining this machine in good working order.
▲
Do not mount tractor when tractor is moving. Avoid serious injury or death from contact
with the rotating tyres. Mount and dismount the tractor only when it is completely stopped,
do not grasp the control levers when mounting or dismounting the tractor.
▲
Always take extreme care when working around overhead obstructions. When working
close to overhead power lines consult your electric company for a safe code of operation.
▲
The boom is designed only to position the cutterhead which is attached to it. Never
attempt to lift, pull, or push other objects with it. Serious injury could result from a structural
failure when the boom is used for purposes other than those for which it was designed.
▲
The boom on this machine has a safety ‘breakback’ system with automatic return to the
work position, never allow anyone to stand in front of the boom or cutterhead in a position
where they could be injured if the boom were to move forward suddenly.
▲
Always at all times keep fingers away from the cutter knife as it can be operated by a
movement of the crankshaft fly wheel caused by gravity even though the tractor engine is
switched off. When clearing any blockage always lay the cutterbar flat on the ground,
switch off the tractor, clamp the cutter knife firmly and remove the blockage using a
suitable tool.
▲
Do not operate the machine with hydraulic oil leaking. Oil is expensive, and its presence
could present a hazard. Do not check for leaks with your hand-use cardboard. High-
pressure oil can penetrate the skin and cause GANGRENE. If oil does penetrate the skin,
have it surgically removed at once by a surgeon knowledgeable in this procedure.
▲
Never become complacent and ignore any safety instructions. Always check all nuts,
bolts, hoses and other fixings daily for tightness, security and damage. Repair immediately
if require Always transport the machine in the recommended position (see instructions in
transport section) with the cutterbar guard in position.
