Cutting And Adjusting Hedges; Routine Maintenance - Stiga SHT 660 K Operator's Manual

nerates an average sized
field, but it is not however possible to ex-
clude the possibility of interference on any
active or passive medical devices that opera-
tors may be wearing; this could be risky for
their health conditions. All those using medi-
cal devices should always consult their GP,
or the device manufacturer, before using this
machine.
WARNING! Always wear suitable cloth-
ing when using the machine. Your Dealer can
provide you with all the information on the
most suitable accident-prevention devices to
guarantee your safety.
WARNING! If something breaks or an
accident occurs during mowing, turn off the
engine immediately and move the machine
away to prevent further damage; if an ac-
cident occurs with injuries or third parties
are injured, carry out the first aid measures
most suitable for the situation immediately
and contact the medical authorities for any
necessary health care. Carefully remove any
debris that might cause damage or harm per-
sons or animals should it not be seen.
3.1 CUTTING PROCEDURES
WARNING! When cutting, always hold
the machine firmly with both hands.
WARNING! Immediately stop the machi-
ne if the blades block while running or if they
get caught up in the hedge branches.
It is recommended to trim the two vertical sides
of the hedge before trimming the top.
Adjust the machine's handgrip according to the
type of cutting (see 1.4).
3.1.1 Vertical cutting (Fig. 6)
Proceed by cutting using curved movements
from the bottom towards the top, keeping the
blade as far from the body as possible.
3.1.2 Horizontal cutting (Fig. 7)
The best results will be obtained with the blade
slightly inclined (5° - 10°) in the direction you are
cutting, proceed with a curved movement, slowly
and without interruptions, especially in the case
of very thick hedges.
3.2 WHEN WORK IS FINISHED

When you have finished your work:
– Stop the machine as indicated previously (see
2.3).
– Wait for the blades to stop and replace the pro-
tection device.

4. ROUTINE MAINTENANCE

Correct maintenance is essential to maintain
the original efficiency and safety of the machine
over time.
WARNING! During maintenance opera-
tions:
– remove the spark plug cap.
– Wait until the engine is sufficiently cold.
– Use protective gloves when handling the
blades.
– Keep the blade protection devices on,
except when intervening directly on the
blade.
– Never dispose of oils, fuel or other pollut-
ing materials in unauthorised places.
4.1 STORAGE
At the end of each working session, carefully
clean the machine of dust and debris, and make
sure that there are no damaged parts; replace
any faulty parts and lubricate the blades to pre-
vent rust.
The machine must be preserved in a dry area,
protected from all weather conditions and with
the blade protection device correctly fitted.
4.2 CLEANINGTHE ENGINE
AND THE SILENCER
To reduce fire risks, periodically clean the cylin-
der fins with compressed air and clear the silenc-
er area from branches, leaves or other debris.
4.3 CLEANING THE AIR FILTER
IMPORTANT Cleaning the air filter is essential
to guarantee the efficiency and duration of the
machine.
It must be cleaned after every 8-10 working
hours.
To clean the filter (Fig. 8):
– Loosen the knob (1) remove the cover (2) and
the filter element (3).
– Wash the filter element (3) with soap and wa-
ter. Do not use petrol or other solvents.
– Leave the filter to dry in the open air.
