Air Filter; Oil Pump And Strainer - Jonsered 49 SP Manual Manual

Air filter
Clean the air filter once daily with soapy water, gasoline
or kerosene to ensure that the engine always gets the
corr~~t fuel/air mixture. A clogged air filter interferes
wil~llooth running and increases gas consumption.
Oil pump
Chain and bar lubrication is automatic. Normally the oil
pump requires no attention. However, clean oil and a
clean oil tank are necessary to ensure trouble-free func-
tion. Use only approved chain saw oil.
See the arrow for the position of the oil pump.
The flow of oil to the chain can be regulated by an adjust-
ing screw accessible through the opening under the saw.
See the figure.
The oil pump is factory-set for normal lubrication.
For normal setting, first turn the adjusting screw clock-
wise as far as it will go. (In this position the oil flow is
shut off.) Then back the screw off approximative 111 to
2 turns.
N~~ tighten the adjusting screw beyond the point of
reSiST'dnce.
The oil feed setting should be such that the oil and the
fuel tanks run empty at the same time.
Oil strainer

(
A clogged strainer screen is easily cleaned as follows.
Remove the strainer cap and the screen. Drain off the
remaining oil. Clean the screen. Fill the oil tank half full
with fuel mixture or kerosene and shake thoroughly. Drain
off, and fill th~ oil tank with fresh saw chain' oil. Check
that the chain lubrication system is in working order.
Never use waste oil!
