MTD 112-530 - Manual (Page 5)

OPERATION
1. Before starting engine, check LUBRICATION
INSTRUCTIONS.
2. Check lockout control handle for proper operation.
If too great a pressure is needed to operate these
controls, damage can be done to both the mechanism
and the rods. Readjust so only slight pressure is
needed to operate the blade engaging control. See
ASSEMBLY INSTRUCTIONS Step 9.
3. Service engine with gasoline and oil. See engine
instructions for complete care and maintenance of
engine. READ DIRECTIONS CAREFULLY.
4. Be sure engine crankcase is filled to capacity with
proper grade of oil.
5. Move control handle to “OFF” position.
6. Move throttle control lever to “Choke” position.
7. Crank engine. Move throttle control lever to “Fast”
position as soon as engine fires. Use choke as
needed to keep engine running duringwarm up period.
8. Put blade into motion by moving blade control handle
to “On” position.
To engage the blade with the engine running . . .
a. Move the throttle control lever to “Fast” position.
b. Engage the blade engagement handle SLOWLY.
c. Adjust engine speed.
9. A brief break-in period is essential to insure maxi­
mum engine and mower life. This consists of running
the engine a half speed for a period of time required
to use one tank of gasoline. It is also recommended
to change crankcase oil after the first five hours of
operation or as operating conditions dictate. Always
check oil before operating the mower. BE SURE
CRANKCASE IS FULL.
10. Proper lubrication must be maintained at all times.
11. Appropriate clothing should be worn when cutting
brush or heavy weeds. Safety shoes and safety
glasses are highly recommended.
12. The engine is stopped by moving the throttle control
lever to “STOP” position.
3. Cutting height adjustment is made by removing and
moving axle bolts to the desired positions. Cutting
height will be raised as axle bolts are moved to
lower mounting holes and lowered as axle bolts are
moved to higher mounting holes. All axle bolts must
be mounted in the same relative position to the deck.
When wheels are mounted to the deck, the crown
shape washers must be assembled with the crown
away from the deck. This is necessary to prevent
the axle bolts from loosening.
4. If throttle adjustment becomes necessary, the throttle
control wire may be reset as follows:
a. Loosen, but do not remove, screw securing throttle
control wire assembly at engine.
b. Move throttle control lever on handle to “Choke”
position.
c. Move lever to which control wire is fastened to
engine to full choke position. Retighten screw to
secure throttle control wire assembly.
LUBRICATION
Important; Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind
of work on the lawn mower.
1. Wheel bearings are ball bearings. Use SAE 30 engine
oil.
2. Throttle — Periodically lubricate throttle control
lever and entire length of throttle wire assembly
with a few drops of SAE 30 engine oil for ease of
operation.
3. Engine — Follow engine m a n u a l for lubrication
instructions. Check oil level before each mowing.
4. Friction point between idler bracket assembly (Ref.
No. 94) and deck should be greased once each
season with a multi-purpose grease.
5. Blade Spindle A s s e m b l y — The blade spindle
assembly is equipped with a grease fitting. Use
grass discharge chute for access to the fitting
located under the deck. Use multipurpose grease.
Lubricate PRIOR to initial use and every 25 hours
thereafter. CAUTION: Be sure spark plug wire is
disconnected and grounded.
6. Protective Shield — The pivot points on the protec­
tive shield should be lubricated periodically with
oil to prevent any rust or binding up.
7. Chute Deflector — The torsion spring and pivot
point should be lubricated periodically with oil to
prevent any rust or binding up. Deflector must work
freely.
ADJUSTMENT
1. Handles may be adjusted by changing the position
of the lower support mounting holes. When this
change is made, it may also be necessary to check
the adjustment of the control rod. See Step 9 in
ASSEMBLY INSTRUCTIONS.
2. Control rod adjustment is made as shown in ASSEM­
BLY INSTRUCTIONS Step 9.
MAINTENANCE
Important: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind
of work on the lawn mower.
1. Cutting Blade — Remove all nuts and bolts holding
the blade to the blade hub.
