TO SHARPEN BLADE
NOTE: We do not recommend
sharpening blade - but if you do, be sure
the blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will
cause eventual damage to lawn mower
or engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, drive a nail
into a beam or wall. Leave about one
inch of the straight nail exposed. Place
center hole of blade over the head of
the nail. If blade is balanced, it should
remain in a horizontal position. If either
end of the blade moves downward,
sharpen the heavy end until the blade
is balanced.

• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for
damage or deterioration. Through
normal use it will wear. If catcher
needs replacing, replace only with a
manufacturer approved replacement
catcher. Give the lawn mower model
number when ordering.
DRIVE WHEELS
Check front drive wheels each time
before you mow to be sure they move
freely.
The wheels not turning freely means
trash, grass cuttings, etc. are in the drive
wheel area and must be cleaned to free
drive wheels.
If necessary to clean the drive wheels,
check both front wheels.
• Remove hubcaps, hairpin cotters and
washers.
• Remove wheels from wheel adjusters.
• Remove any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel gear teeth.
• Put wheels back in place.
• If after cleaning, the drive wheels do
not turn freely, contact your nearest
authorized service center.
GEAR CASE
• To keep your drive system working
properly, the gear case 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 case is filled with lubricant to
the proper level at the factory. The only
time the lubricant needs attention is if
service has been performed on the
gear case.
• If lubricant is required, use only Texaco
Starplex Premium 1 Grease, Part No.
750369. Do not substitute.

LUBRICATION

NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
these multi-viscosity oils will result in
increased oil consumption when used above
32°F. Check your engine oil level more
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 five (5) hours of
continuous use. "13ghten oil plug securely
each time you check the oil level.
