A WARNING: Periodically inspect th(» blade
adapter for cracks, especially if you
strike a foreign object. Replace when
necessary.
When sharpening the blade, follow the origins I angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grir ding to
prevent an unbalanced blade. An unbalanced blade
will cause excessive vibration when rotating at high
speeds, may cause damage to the mower an i could
break, causing personal injury.
It is recommended that the blade always be removed
from the adapter for the best test of balance.
The blade can be tested by balancing it on si round
shaft screwdriver. Remove metal from the heavy side
until it balances evenly.
Before reassembling the blade and the blade adapter
to the unit, lubricate the engine crankshaft Sind the
inner surface of the blade adapter with light oil.
Lubricating the bolt holes, bolts and inner surface of
the nuts with light oil is also recommended. A 4 oz.
plastic bottie of light oil lubricant is avaiiable Order
part number 737-0170. Engine oil may also be jsed.
When replacing the blade, be sure to install tha blade
with the side of the blade marked “Bottom” (or with
part number) facing the ground when the mower is in
the operating position.
Blade Mounting Torque
Center Boit: 450 in. lbs. min., 600 in. lbs. max.
Blade Adapter Bolts: 200 in. lbs. min., 350 in. lb a. max.
To insure safe operation of your unit, ail nuts and bolts
must be checked periodically for correct tightness.
DECK
The underside of the mower deck should be c leaned
after each use to prevent a buildup of grass cli apings,
leaves, dirt or other matter. If this debris is allc wed to
accumulate, it will invite rust and corrosion, and may
cause an uneven discharge of grass clippings at the
next cutting.
The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool (make certain the
spark plug wire is disconnected).
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read an(i follow
instructions carefully.
Service air cleaner every 25 hours under normal con­
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser­
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom­
mended at the start of each mowing season; check
engine manual for correct plug type and gap specifi­
cations.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is essential to
engine performance and life. Be certain to remove all
grass, dirt and combustible debris from muffler area.
REAR FLAP REPLACEMENT
The rear flap is attached to the back of the mower
deck, and is designed to minimize the possibility that
objects will be thrown from the rear of the mower
toward the operator. If the rear flap becomes dam­
aged, replace as follows.
To remove the old rear flap, cut off the flat end of the
wire rod which secures it to the deck using a pair of
side-cutters. Attach the new rear flap using the new
rod provided with the rear flap, bending the ends of
the rod over to secure.
OFF-SEASON STORAGE"

mower for storage.
1. Clean and lubricate mower thoroughly as
described in the lubrication instructions.
2. Refer to engine manual for correct engine storage
instructions.
3. Coat mower’s cutting blade with chassis grease
to prevent rusting.
4. Store mower in a dry, clean area. Do not store
next to corrosive materials, such as fertilizer.
NOTE: When storing any type of power equipment in
an unventilated or metai storage shed, care should be
taken to rust-proof the equipment Using a light oil or
silicone, coat the equipment especially cables and all
moving parts.
