Cold Start; Operation - Stiga BC 636 Manual De Instrucciones

6.3.1 Cold start

"Cold" start means starting
performed at least 5 minutes after
stopping the engine or after refuelling.
IMPORTANT To prevent deformation, the
transmission tube must not be used as a
support for hands or knees during start-up.
IMPORTANT To avoid breakage, do not
pull the rope along its entire length, do not
slide it along the edge of the guide hole
and release the knob gradually to prevent
it rewinding in an uncontrolled way.
1. Make sure that the switch
(Fig.11.A) is in position "I".
2. only for models with choke:
Engage the choke, moving the lever
to "B" position (Fig. 18.E).
3. Press the primer control button (Fig. 11.F)
10 times to facilitate carburettor ignition.
Make sure the hole is covered by your
finger when you press the command.
4. Hold the machine firmly on the ground,
with one hand on the drive unit, to avoid
losing control of it when starting (Fig. 13).
5. Slowly pull the starter knob by 10-
15cm, until you feel a certain resistance,
and then pull again a few times until
you hear the first combustions.
6. only for models with choke:
Disengage the choke, moving the lever
to "A" position (Fig. 18.E).
7. Pull the starter knob again until the
engine is properly switched on.
8. Operate the throttle lever briefly (Fig.
11.B) and set the engine to idle.
9. Allow the engine to idle for at least 1
minute before using the machine.
IMPORTANT If the starter rope knob
is operated repeatedly, the engine may
choke and start up may become difficult.
If the engine floods in this way, see section 14.
6.3.2 Hot start
For hot start (immediately after stopping
the engine), follow steps 1 - 2 - 3 - 4 -
6 - 7 of the previous procedure.

6.4 OPERATION

NOTE Before starting any tasks for
the first time, get to know the machine,
learn the most suitable cutting techniques,
make sure your are wearing the harness
correctly, grip the machine firmly and make
the movements required by the job.
To use the machine proceed as follows:
• always keep the machine connected to the
correctly worn harness (see par. 6.1.1).
• when working, the machine must always
be firmly held in both hands, keeping the
power unit on the right of the body and the
cutting unit below the line of the belt.
6.4.1 Work techniques
6.4.1.a Cutting line head
Use ONLY nylon lines. The use of
metal lines, plastic coated metal lines and/
or lines that are not suitable for the head
can cause serious injuries and wounds.
Do not use the machine for sweeping,
tilting the cutting line head. The engine
is powerful enough to throw objects and
small stones 15 metres or more, causing
damage to objects and injury to people;
a. Cutting motion (Scything)
Proceed at a regular pace, with a circular motion
similar to a traditional scythe, without tilting the
cutting line head during the operation (Fig. 14).
First try cutting at the right height in a small
area, so as to then achieve a uniform cutting
height keeping the cutting line head at a
constant distance from the ground.
For heavier cutting it can be useful to tilt the
cutting line head to the left by about 30°.
Do not work in this way if there
is the possibility of causing objects
to be thrown, which could harm
people, animals or cause damage.
