Tuning Minimum Speed; Tuning The Carburettor; Storing; Handling And Transportation - Stiga SP 316 Manual De Instrucciones

8.7.1 Replacing the bar
Replace the bar whenever:
– the groove is not as deep as the
height of the drive links (which
must never touch the bottom);
– the inside of the guide is worn enough
to make the chain lean to one side.

8.8 TUNING MINIMUM SPEED

If the cutting means moves when the
engine is running idle, contact your dealer
or Authorised Service Centre to have the
engine adjusted correctly (par. 8.9).

8.9 TUNING THE CARBURETTOR

The carburettor is tuned by the manufacturer
to achieve maximum performance in all
situations, with a minimum emission of toxic gas
in compliance with the regulations in force.
In the event of poor performance, contact
your Dealer or Authorised Service Centre
for a check of the carburetion and engine.
Carburettor tuning:
T = minimum speed tuning
L = low speed mixture tuning
H = high speed mixture tuning

9. STORING

IMPORTANT The safety regulations to
follow for putting into storage are described
in paragraph 2.4. Strictly comply with these
instructions to avoid serious risks or dangers.
If you are not going to use the machine
for a period of more than 2-3 months, we
recommend you do a few things before putting
it away. This will make it easier when you
want to use the machine again and will also
prevent permanent damage to the engine.
Before putting the machine away:
1. Unscrew the clutch housing nut, remove the
housing and remove the chain and bar.
2. Empty the oil tank, fill with about 100-120 cc
of specific liquid detergent and plug the cap.
3. Refit the guard (Fig. 8.A), without fully
tightening the nut, making sure the
chain brake lever (Fig. 8.B) is inserted
correctly into its seat in the front hand
guard (pulled completely backward).
4. Start the engine and keep it running
until all detergent is used.
5. Start the engine and run it idle until
it uses up all the fuel that is left in
the tank and the carburettor.
6. Wait for the engine to cool.
7. Remove the spark plug.
8. Pour a teaspoon of (new) 2-stroke
engine oil into the spark plug slot.
9. Pull the starter hand grip several
times to deliver oil to the cylinder.
10. Replace the spark plug with the
piston in the dead end upper position
(visible from the spark plug slot when
the piston is at maximum stroke).
11. Clean the machine thoroughly.
12. Check the machine for any
damage. If necessary, contact the
authorised service centre.
13. Store the machine:
– in a dry place
– protected from inclement weather
– with the bar cover guard fitted correctly
– in a place where children cannot get to it
– making sure that keys or tools used
for maintenance are removed.
Before starting to use the machine again:
1. Remove the spark plug.
2. Pull the starter hand grip a few
times to eliminate excess oil.
3. Check the spark plug (par. 8.4).
4. Prepare the machine (chap. 4 chap. 6).

10. HANDLING AND TRANSPORTATION

When handling or transporting
the machine, always:
– stop the machine (par. 6.9).
– wait until the chain is stationary.
– remove the spark plug cap (Fig. 25.A)
– mount the bar cover.
– only hold the machine using the hand
grips and position the bar in the opposite
direction to that used during operation.
When transporting the machine
on a vehicle, always:
– position it so that it does not
cause a hazard to anyone;
– fasten firmly to the means of transport using
ropes or chains to prevent it from tipping
over causing damage and fuel leaks.
