Oil Filter; Bar Chain Maintenance; Checking The Spark Plug - Garland FOREST 1220 Manual De Instrucciones

8.2.4. OIL FILTER

The oil tank is provided with a fi lter (2). This element
is located at the extreme end of the oil hose and it
can be removed oil opening with the help of a piece of
wire bent into a hook or similar device.
Inspect the oil fi lter
periodically. Do not allow
dust to enter the oil tank.
The obstruction of the
fi lter will make it diffi cult
to start the engine or it will
produce abnormalities in
the performance of the engine.
Inspect the oil fi lter and if it is dirty, replace it with a
new one.
If the inside of the oil tank is dirty, it can be cleaned by
rinsing out with petrol.

8.2.5. CHECKING THE SPARK PLUG

Starting up or ignition failures are frequently caused
by a dirty spark plug. Clean the spark plug and check
that the spark plug light is within the correct interval.
(0.6-0.7mm).
8.2.6. CLEANING THE CYLINDER REFRIGERATION
VENTS
The cylinder refrigeration vents
are responsible for cooling the
piston and the cylinder by means
of the entry of air.
The vents must always be kept clean, free from
material that could block air from entering. Dirty vents
mean that the engine will overheat, causing it to seize.
Check and clean the cylinder vents periodically.

8.2.7. BAR CHAIN MAINTENANCE

Invert the bar periodically, in order to avoid it wearing
out unevenly. The edges of the bar rail must always be
kept square.
Check the wear and
the shape of the
edges. If you observe
that the edges have
lost their shape, or a
side wing is deformed,
replace the bar.
When unassembling
the chain bar, remove
the sawdust from the
bar (2) and the oil hole
(1). Oil the chain sprocket.
