• 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.
ENGINE
LUBRICATION
Maintenance, repair, or replacement of the emission control
devices and systems, which are being done at the custom-
ers expense, may be performed by any non-road engine
repair establishment or individual. Warranty repairs must
be performed by an authorized engine manufacturer's
service outlet.
LUBRICATION
Use only high quality detergent oil rated with API service
classifi cation SG–SL. Select the oil's SAE viscosity grade
according to your expected operating temperature.
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.
