ADJUSTING THE CARBURETTOR
ADJUSTING THE CARBURETTOR
The carburettor on your saw has been factory set but may
require some minor adjustments due to a change in operat-
ing conditions. Before adjustment, make sure that the air/fuel
filters are clean and the fuel is properly mixed.
It is recommended that adjustments are done when the chain-
saw is warm and fully assembled.
T - This controls the engine speed at idle. If set too low the
saw will stall. If set too high the chain will move. The saw chain
should not move at engine idle speed, otherwise serious injury
may result.
L - Low speed adjustment screw (this is the low speed jet).
This is the adjustment that controls the air/fuel mixture at idle.
Adjust this screw too rich and the chainsaw will stall at idle
speed. Adjust this screw too lean and the engine will race or
surge. An extremely lean adjustment will also cause the engine
to flood.
H - High speed adjustment screw (this is the high speed jet).
This is the adjustment that controls the air/fuel mixture at high
RPMs. Adjust this screw too rich and the chainsaw will stall,
too lean and it will over rev.
Never adjust the carburettor more than 1/4 turn in either direc-
tion without first testing the saw. To reset your carburettor to
factory settings fully close both the L and H screws by turning
clockwise and then anti clockwise 1 1/2 turns.
