MAINTENANCE
• To check blade balance, you will need a 5/8" diameter
steel bolt, pin, or a cone balancer. (When using a
cone bal anc er, follow the in struc tions supplied with
bal anc er.)
NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not.
• Slide blade on to an unthreaded portion of the steel bolt
or pin and hold the bolt or pin parallel with the ground.
If blade is bal anced, it should remain in a horizontal
po si tion. If either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.
GRASS CATCHER
• The grass catcher may be hosed with water, but must
be dry when used.
• Check your grass catcher often for damage or de te -
ri o ra tion. Through normal use it will wear. If catcher
needs replacing, replace only with ap proved replace-
ment catcher shown in the Repair Parts section of this
manual. Give the lawn mower model number when
ordering.
GEAR CASES
• To keep your drive system working properly, the gear
cases and area around the drive should be kept clean
and free of trash build-up. Clean under the drive cover
twice a season.
• The gear cases are fi lled with lubricant to the proper level
at the factory. The only time the lubricant needs atten-
tion is if service has been performed on the gear case.

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve
starting in cold weather, and you should check your engine
oil level frequently to avoid possible engine damage from
running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the lawn mower is not used for 25 hours in
one year.
Check the crankcase oil level before starting the engine
and after each fi ve (5) hours of continuous use. Tighten oil
plug securely each time you check the oil level.
4. Wipe off any spilled oil from lawn mower or side of
engine.
5. Fill engine with oil. Slowly pour oil down the oil fi ll spout
into the engine.
6. Wait one minute to allow oil to settle. Use guage on oil
fi ll cap/dipstick for checking level. Insert dipstick into
the tube and rest the oil fi ll cap on the tube. DO NOT
thread the cap into the tube when taking reading.
7. Continue adding small amounts of oil and rechecking
the dipstick until it reads full. DO NOT overfi ll, or engine
will smoke on startup.
8. Always be sure to retighten oil fi ll cap/dipstick before
