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, ddve 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.

GRASS
CATCHER
• 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 ddve 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 tum freely,
contact your nearest
authorized
service center.
GEAR
CASE
• To keep your drive system working
properly, the gear case and area
around the ddve 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 I Grease, Part No.
750369.
Do not substitute.
ENGINE
LUBRICATION
Use only high quality detergent oil rated
with API service classification SF, SG or
SH.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.

RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
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. Tighten oil plug
securely each time you check the oil
level.
