Chain Oil; The Oil Pump; Fuelling - Jonsered 2054 Operator's Manual

Chain oil

• The chain lubrication
system is automatic. Always
use special chain oil with
good adhesive
characteristics.
• In countries where no
special chain oil is available,
transmission oil EP 90 can
be used.
• Never use waste oil. This
results in damage to the oil
pump, the bar and the
chain.
• It is important to use oil of
the right viscosity according
to the air temperature.
• In temperatures below 0 o
(32 o F) some oils become
too viscous. This can
overload the oil pump and
result in damage to the oil
pump components.
• Contact your servicing
dealer when choosing chain
oil.

The oil pump

The chain is lubricated by an automatic oil pump. The pump
does not normally require any maintenance, provided that clean
chain oil (of special type) is used, and that no dirt is allowed to
get into the tank during filling.
The flow of oil to the chain can be regulated by means of an
adjuster screw as indicated in the illustration, using a
screwdriver or combination key. For maximum flow, turn the
screw in a clockwise direction as far as it will go.
The oil pump is adjusted at the factory to supply a normal flow
of oil to the chain. The settings should be such that the saw's
fuel and oil tanks run dry at the same time.
FUEL HANDLING
C

Fuelling

!
Taking the following precautions, will lessen
the risk of fire.
• Do not smoke or place warm objects in the vicinity of
the fuel.
• Always shut off the engine before refuelling.
• Slowly open the fuel cap, when filling fuel, so that
possible overpressure is slowly released.
• Tighten the fuel cap carefully after fuelling.
• Always move the saw from the fuelling area before
starting.
!
WARNING!
The catalytic converter muffler gets very hot
during and after use. This also applies during
idling. Be aware of the fire hazard, especially
when handling the saw near flammable
substances or vapours.
Clean around the fuel cap.
Clean the fuel and chain oil
tanks regularly. The fuel filter
should be changed at least
once a year. Contamination in
the fuel tanks causes
malfunction. Make sure the
fuel is well mixed by shaking
the container before fuelling.
The volume of chain oil and
fuel tanks are adjusted to
each other. Therefore, always
fill chain oil and fuel at the
same time.
