Operating Instructions; Preparing To Work - Stiga SHT 660 K Operator's Manual

machine is always in safe working condition.
Routine maintenance is essential for safety and
for maintaining a high performance level.
2) Do not store the machine with fuel in the tank
in an area where the fuel vapours could reach
an open flame, a spark or a strong heat source.
3) Allow the engine to cool down before storing
in any enclosure.
4) To reduce fire hazards, keep the engine, ex-
haust silencer and fuel storage area free from
branches, leaves, or excessive grease; never
leave containers with the cut debris inside the
storage area.
5) If the fuel tank has to be emptied, this should
be done outdoors once the engine has cooled
down.
6) Always wear protective gloves when handling
the cutting device.
7) Make sure the blades are well sharpened. All
operations on the blades require a certain level
of experience and specialised tools. For safety
reasons, take them to a specialised centre to be
sharpened.
8) For safety reasons, never use the machine
with a worn or damaged cutting device or other
parts. Damaged parts are to be replaced and
never repaired. Only use original spare parts.
Parts that are not of the same quality can seri-
ously damage the equipment and compromise
safety.
9) Store the machine out of the reach of chil-
dren!
E) TRANSPORTATION AND HANDLING
1) Whenever the machine is to be inspected,
handled or transported you must:
– turn off the engine, wait for the blades to stop,
disconnect the spark plug cap and wait until
the machine cools down;
– apply the protection devices to the blades;
– only hold the machine using the handgrips and
position the blades in the opposite direction to
that used during operations.
2) When using a vehicle to transport the ma-
chine, position it so that it can cause no danger
to persons and fasten it firmly in place to avoid it
from tipping over, which may cause damage or
fuel spillage.

1. PREPARING TO WORK

1.1 CHECKING THE MACHINE
Before starting work please:
– Check that all the screws on the machine and
the blade are tightly fastened;
– check that the blades are sharp and there are
no signs of any damage;
– check that the air filter is clean;
– check that the protection devices are well fas-
tened and working efficiently;
– check the handgrips are well fastened.
1.2 PREPARING THE FUEL MIXTURE
This machine is fitted with a two-stroke engine
which requires a mixture of petrol and lubricat-
ing oil.
IMPORTANT Using petrol alone will damage the
engine and will cause for invalidation of the war-
ranty.
IMPORTANT Only use quality fuels and oils to
maintain high performance and guarantee the du-
ration of the mechanical parts over time.
1.2.1 Petrol characteristics
Only use unleaded petrol with a fuel grade of at
least 90 ON.
IMPORTANT Unleaded petrol tends to create
deposits in the container if preserved for more
than 2 months. Always use fresh petrol!
1.2.2 Oil characteristics
Only use top quality synthetic oil specifically for
two-stroke engines.
Your Retailer can provide you with oils which
have been specifically developed for this type of
engine, and which are capable of guaranteeing a
high level of protection.
The use of these oils makes it possible to pre-
pare a 2% mixture, consisting in 1 part oil to 50
parts petrol.
1.2.3 Preparation and preservation
of the fuel mixture
DANGER! Petrol and the fuel mixture are
highly inflammable!
– Keep the petrol and fuel mixture in homolo-
gated fuel containers, in safe place, away
from any flames or heat sources.
– Never leave the containers within the reach
of children.
