THROWN DEBRIS
The trimmer will throw debris in the direction of blade movement
at the point of contact.
The cutting line head or blade on the Qualcut 3300ST trimmer
rotates anti-clockwise as viewed from the operator’s position,
so tilting the cutting line head to the right will throw debris away
from you, and tilting to the left will throw debris towards you.
If the cutting line head or blade is held parallel to the ground,
debris will scatter in all directions, and there will be greater
friction which will wear out the cutting line or blade sooner.
When operating the trimmer near a hard surface such as a wall,
work from an angle where debris that strikes the hard surface
will ricochet away from you.

SAFE OPERATING
PRACTISES
Be very careful when operating the brushcutter over uneven or
rough ground, and when the ground is wet and slippery. Watch
out for hidden obstacles that could cause you to stumble.
Operate the brushcutter only under conditions with good visibility.
Do not operate the brushcutter where you cannot see what it
is cutting.
WARNING! Rotating cutting lines can cause serious
abrasions and cuts, and blades can cut deeply.
• Keep away from the cutting lines or blade whenever
the engine is running.
• Always stop the engine, and be sure the cutting
line head has stopped turning, before inspecting
or handling the cutting lines or blade.
•
Immediately stop using all your power equipment and consult
a doctor if you feel tingling, numbness or pain in the fingers,
hands,wrists or arms. The sooner RSI / CTS is diagnosed,
the more likely permanent muscle damage can be prevented.
Gravel, loose stones, etc. can be picked up by the nylon cutting
lines or blade and thrown many feet with enough force to cause
serious personal injury and/or property damage. Before crossing
gravelled areas, release the throttle trigger to stop the cutting
line head or blade.
WARNING! Keep all bystanders, especially children
and pets at least 15m from the operating area.

BLADE THRUST (KICKBACK)
Blade thrust (kickback) is the sudden, forceful, and uncontrolled
movement of a blade-equipped brushcutter that may occur if
the blade binds in the cut or strikes a solid object. It throws the
trimmer in the direction opposite blade rotation at the point of
contact, and the jolt received by the operator can result in further
loss of control.
To reduce the risk of loss of control:
• Replace or resharpen dull blades. Dull blades are more
likely to bind in the cut and cause blade thrust.
• Watch out for hidden obstacles, such as rocks, stumps,
roots, etc., that could cause the blade to kick back if struck.
Blade thrust is more likely to occur in areas where it is difficult
to see what is being cut.
• Understand the reaction forces of the blade.
