MTD 113-112 - Manual (Page 6)

OPERATION
NOTE: For shipping purposes your mower is set with the
wheels in a low cutting height position. For best results
raise the cutting position until it is determined which height
is best for your lawn. See adjustments.
2. Move throttle control lever on handle to
position.
'FAST"
3. Move lever, to which control wire is fastened at engine,
to full op>en position and retighten screw to secure
throttle control wire assembly.
1. Service engine with gas and oil. See Engine Manual
packed with lawn mower for complete instructions for
the care and maintenance of engine. Read Directions
Carefully.
2. When ready to start engine, place throttle control lever,
on handle, in "START" position and start engine in
accordance with instructions in Engine Manual. After
engine starts, move throttle control lever, on handle, to
desired engine speed. The engine is stopped by placing
control lever on handle in the "STOP" position.
3. Be sure that lawn is clear of stones, sticks, wire or other
objects which could damage lawn mower or engine. For
best results and to insure more even grass distribution,
do not mow when lawn is excessively wet.
ADJUSTMENTS
CAUTION: Do not at any time make any adjustment to
lawn mower without first stopping engine and
disconnecting spark plug wire.
CUTTING HEIGHT - (For Models 113-112 and 122)
Adjustment may be made by removing and moving wheel
studs to desired position. Cutting heights will be raised as
wheel studs are moved to a lower hole and lowered as wheel
studs are moved to a higher hole in the deck. All wheel
studs must be mounted in a relative position to the deck.
EASY CUTTING HEIGHT-(Optional for 113-132 and
142)
An adjusting plate and thumb lever at each wheel position
provides cutting height adjustment. Each adjusting plate has
five holes. Height of cut will be changed when the thumb
lever is moved from one hole to another. Simply depress
thumb lever towards wheel and move wheel and lever
assembly to desired position. All wheels must be positioned
in relative height of cut positions.
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.
LUBRICATION
IMPORTANT: — Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind of
work on lawn mower.
WHEELS — Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
PROTECTIVE SHIELD - The pivot points on the
protective shield should be lubricated periodically with
light oil to prevent any rust or binding.
CHUTE DEFLECTOR - The torsion spring and pivot point
should be lubricated periodically with light oil to prevent
any rust or binding. Deflector most work freely.
THROTTLE - Periodically lubricate throttle control lever
and throttle wire assembly with a few drops of light oil
(S.A.E. No. 10 or 20) for ease of operation.
ENGINE — Follow engine manual for lubrication
instructions.
MAINTENANCE
CUTTING BLADE: The blade may easily be removed for
grinding or replacement as follows:
1. Remove bolt and lock washer holding blade and blade
adapter to engine crankshaft.
2. Remove blade and blade adapter from engine crankshaft.
3. Remove two bolts, lock washers and nuts holding blade
to the blade adapter (if necessary).
When sharpening blade, follow the original angle of grind as
a guide. It is extremely important that each cutting edge
receives an equal amount of grinding to prevent an
unbalanced blade. An unbalanced blede will cause excessive
vibration when rotating at high speeds and may cause
damage to the mower.
Upon reassembly, make certain all parts are assembled
properly and tightened securely.
