Little Wonder 2300 - Manual (Page 10)

10.
A. Lubrication
1. A few drops of a light #10 oil should be placed on the
back edge of each adjusting screw head approximately
after every 4 hours of normal operation.
2. To obtain trouble free trimming, it is necessary to keep the
blades lubricated and clean. The gum that collects and
builds up on the blades can be removed with a 50-50
mixture of kerosene and #10 oil. As petroleum products
can shorten the life of some plastics it is necessary to
remove excess oil-kerosene mixture from the plastic parts.
3. When blades are replaced, or any other time that the
bottom cover plate is removed, the grease level should be
checked for proper amount (approximately 1/2 full in the
area of the gears) and a new gasket should be used to
insure proper seating of the cover plate. Grease should be
added every 25 hours of use. Use EP2 white lithium grease
in the gear housing.
4. Lubricate male spline part of the drive shaft with
EP2 White Lithium grease.
B. Engine
1. Air Filter
a. Clean the air filter before each
use. Remove wing nut and air
filter cover.
b. Inspect the air filter and clean
in warm, soapy water monthly. Dry completely before
re-installing.
c. If filter is excessively dirty or no longer fits properly,
replace it.
d. Re-install filter making sure it is seated properly.
e. Re-install cover onto air cleaner case and secure with
wing nut.
2. Fuel Filter
Inspect for blockage when the fuel tank is low on fuel
3 Muffler
Equipped with a spark arrester to prevent red hot carbon
from flying out of the exhaust outlet. Periodically inspect
and clean as necessary the spark arrester with a wire brush.
4. Cooling Fins
Remove dirt and debris from around cooling fins and
exhaust before each use. Proper air circulation is
essential for engine performance and life.
Maintenance C. Idle Speed Adjustment
1. Before adjusting carburetor, clean or replace air filter and
muffler’s spark arrestor screen. Make sure that the hedge
trimmer blades are properly adjusted.
2. The idle speed adjustment screw
controls the throttle opening at idle
position. Turn idle speed
adjustment screw (1)clockwise
until blades begin moving.
3. Then turn the screw counter-
clockwise until blades stop moving.
Next, turn the screw counter-clockwise an additional
1/4 turn.
4. If tachometer is available, idle speed should be set as
specified in the owner’s manual.
D. Long Term Storage (over 60 days)
1. Store your trimmer in a dry and dust free space, out of the
reach of children.
2. Place the ignition switch in the stop position.
3. Clean the engine and blades thoroughly and coat the
blades with #10 oil to prevent rust.
4. Perform all required maintenance and service found in this
manual.
5. Aged fuel is one of the major causes of engine starting
failure. Before storing the unit, empty the fuel tank and run
the engine until it uses all the fuel left in the fuel line and
carburetor. Store the unit indoors, taking necessary
measures for rust prevention.Pull the starter rope several
times to remove the fuel from the carburetor.
6. Remove the spark plug and pour 1/4 oz. of fresh, clean,
two-stroke engine oil into the cylinder via the
spark plug hole. Cover the hole with a rag and pull the
starter rope 2-3 times.
7. While looking through the spark plug hole pull the starter
rope slowly until the piston reaches the top of it’s stroke
and stop.
8. Install the spark plug, but leave the ignition cable
disconnected.
WARNING – DANGER
