Operation - Stiga SP 386 Manual De Instrucciones

Before starting the machine:
1. Place the machine firmly on the ground.
2. Remove the bar cover guard (Fig. 1.K) and
the spiked bumper guard (Fig. 1.J) (if fitted).
3. Make sure the bar and the chain are not
touching the ground or any other object.
4. Make sure the chain brake
is engaged (par. 5.7).
IMPORTANT To avoid breaking the starter
cable, do not pull the whole length of it or
let it slide along the edge of the cable guide
hole. Release the starter handgrip gradually,
to prevent it flying back uncontrollably.
IMPORTANT Never wind the
starter cable around your hand.
Never start the chain saw by holding
on to the starter cable and allowing it
to fall. This is an extremely dangerous
method as you lose complete control
over the machine and the chain.
NOTE The switch is always in
the start position (par. 5.1).
6.3.1 Startup from cold
A "cold " start of the engine means

starting, the valve automatically
returns to its original position.
4. Hold the machine firmly on the ground
with your hand on the front handgrip and
your foot in the rear handgrip, to avoid
losing control during starting (Fig. 18).
If the machine is not held firmly,
the force of the engine could cause
the user to lose his balance or direct
the bar towards him or an obstacle.
5. Pull the starter handgrip slowly for 10
- 15 cm until you feel some resistance,
then tug it a few times until you hear
the engine start to tick over.
6. Disengage the starter (Fig. 11.A) by
turning the lever to position «A».
7. Pull the starter grip again until
the engine starts as normal.
8. When the engine has started, press
the throttle control lever (Fig. 12.B)
to disengage the pre-throttle device
and allow the engine to run idle.
9. Disengage the chain brake (par. 5.7).
IMPORTANT Do not let the engine
run at high speed with the chain brake
engaged, as this could cause overheating
and damage to the clutch.
10. Let the engine run idle for at least 1
minute before using the machine.
IMPORTANT If the starter handgrip is
pulled repeatedly with the starter on, it may
flood the engine and make starting difficult. "
If the engine floods (see paragraph 15.5).
6.3.2 Warm start
When hot starting (immediately
after stopping the engine):
1. Press the primer device button (Fig.
12.A) 6 times to prime the carburettor.
2. For model SP 526 only:
Press the pressure relief valve (Fig. 13.E).
NOTE Immediately after the engine
starting, the valve automatically
returns to its original position.
3. Engage and disengage the starter,
by turning the lever to position «B»
and then immediately back to position
«A» (Fig. 11.A, Fig. 11.B); this will
engage the pre-throttle device.
