MTD 330 - Cutting Height Adjustment; Carburetor Adjustments

For the best results, do not cut wet grass b(icause
it tends to stick to the underside of the mower,
preventing proper discharge of grass clippings,
and could cause you to slip and fall. New grass,
thick grass or wet grass may require a nc rrower
cut. Blade speed should be adjusted to the condi¬
tion of the lawn.
For best results, cut off one-third or less of the
total length of the grass. Lawn should be cut in
the fall as long as there is growth.
This mower is designed to be operated at full
throttle to give you the best cut and do th3 most
effective job of bagging the cut grass.
IMPORTANT
If you strike a foreign object, stof
the engine. Remove wire from sparl.
plug, thoroughly inspect the mowe'
for any damage, and repair the
damage before restarting and
operating the mower. Extensive
vibration of the mower during opera¬
tion is an indication of damage. The
unit should be promptly inspected
and repaired.
ADJUSTMENTS
Do not at any time make any adjust¬
ment to lawn mower without first
stopping engine and disconnectinq
spark plug wire.
CUTTING HEIGHT ADJUSTMENT
Units With Height Adjustment Brackets
An adjusting plate and thumb lever at eacn wheel
position provides cutting height adjustme it. Each
adjusting plate has five holes. Height of cut will
be changed when the thumb lever is movsd from
one hole to another. Simply depress ttie lever
towards wheel and move wheel an i lever
assembly to desired position. See figure 17.
Cutting height will be raised as front £ nd rear
levers are lowered. Cutting height will be owered
as front and rear levers are raised. All whe<'ls must
be placed in the same relative position.
For rough or uneven lawns, move the whe els to a
position which will give a higher cutting leight.
FIGURE 17.
Units Without Height Adjustment Brackets
Adjustment may be made by removing and moving
axle bolts to desired position. Cutting heights will
be raised as axle bolts are moved to a lower hole
and lowered as axle bolts are moved to a higher
hole in the deck. All axle bolts must be mounted in
the same relative position. Belleville washers
must be assembled on the inside and outside of
the deck so that the cupped side of the washers
are against the deck.
THROTTLE
If adjustment becomes necessary, the throttle
control wire assembly can be reset as follows:
1. Loosen, but do not remove, screw securing
throttle control wire assembly at engine. See
figure 8.
2. Move throttle control lever on handle to
“FAST” position.
3. Move control lever on engine to full open posi¬
tion. Retighten screw to secure throttle con¬
trol wire assembly.
CARBURETOR ADJUSTMENTS
\ WARNING t
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
