MOWING
e The nylon line will effectively mow large areas of heavy
grass and/or weeds. Use the standard 5-6 inches of line
and operate at full throttle,
e When mowing cultivated areas such as lawns hold the
cutter head parallel to the ground to avoid scalping.
SCALPING
e The cleaning of weeds and grass right down to the earth
can be accomplished very easily with the nylon line.
e Scalping around trees and bushes is particularly effective,
but care should be exercised not to bruise the bark of
yound and sensitive growth.
e In flower beds, always remember that the nylon line will
cut in a complete circle to avoid cutting flowers instead
of weeds. See Fig. 8

CARBURETOR
e Carburetor is set at the factory. So normally, further
adjustment is unnecessary. If readjustment is required,
refer to the following instructions.
The diaphragm carburetor has three external adjustments,
and to some extent, the adjustment of each will affect the
other two. It will be necessary, therefore, to readjust each
until satisfactory performance 15 achieved.
1. Idle speed adjusting screw.
This adjustment controls the throttle opening in the idle
position.
2. Low (LO) speed needle screw,
The low speed needle controls the volume of fuel/oil
mixture at low engine speed. М also controls the supple-
mentary fuel required to obtain smooth progression from
idling to high speed.
3. High (HI) speed needle screw,
