Always shut off the engine before
leaving the unit unattended.
Check the cutting tool at regular short
intervals. If behavior of cutting tool
changes, check it immediately:
–
Turn off the engine. Hold the unit
firmly and press the cutting tool into
the ground to bring it to a standstill.
–
Check condition and tightness –
look for cracks.
–
Check sharpness.
–
Replace damaged or dull cutting
tools immediately, even if they have
only superficial cracks. Perform
ringing test on metal cutting tools.
Clean grass and scrub off the cutting
tool mounting at regular intervals. If the
cutting tool or deflector becomes
clogged or stuck, always turn off the
engine and make sure the cutting tool
has stopped before cleaning.
To reduce the risk of unintentional
engine start and injury, always shut off
the engine and remove the spark plug
boot before replacing the cutting tool.
Never repair damaged or cracked
cutting tools by welding, straightening or
modifying the shape (out of balance).
This may cause parts of the cutting tool
to come off, hit the operator or
bystanders at high speed and result in
serious or fatal injuries.
When using mowing heads
Mount the additional parts specified in
the instruction manual to the cutting tool
deflector.
Use the approved deflector with a
properly mounted line limiting blade to
ensure the nylon lines are trimmed to the
correct length.
To reduce the risk of injury, always shut
off the engine before adjusting length of
nylon line on manually adjustable
mowing heads.
Using the unit with over-long nylon
cutting lines increases the load on the
engine and reduces its operating speed.
This causes the clutch to slip
continuously and results in overheating
and damage to important components
(e.g. clutch, polymer housing
components). There is also a risk of
injury from the cutting tool rotating while
the engine is idling.
When using metal cutting tools
Sharpen metal cutting tools regularly as
specified. Dull or improperly sharpened
cutting edges can put a higher load on
the cutting tool and increase the risk of it
cracking or shattering – risk of injury.
