TO SHARPEN BLADE
NOTE: We do not recommend sharpening
the 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 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.
GRASS CATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for dam-
age or deterioration. Through normal
use it will wear. If catcher needs replac-
ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
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 Elf Mul-
tis EP00. Do not substitute.

LUBRICATION
Use only high quality detergent oil rated with
API service classification SG-SL. Select the
oil's SAE viscosity grade according to your
expected operating temperature.
SAE VISCOSITY GRADES
F -20 0 30 32 40 60 80 100
c -1o -2; -1; ; ;o _o 1o 40
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°R 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 op-
eration orat least once a year if the 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.
TO CHANGE ENGINE OIL
NOTE: Before tipping lawn mower to drain
oil, empty fuel tank by running engine until
fuel tank is empty.
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Remove engine oil cap; lay aside on a
clean surface.
3. Tip lawn mower on its side as shown
and drain oil into a suitable container.
Rock lawn mower back and forth to re-
move any oil trapped inside of engine.
Container
4. Wipe off any spilled oil from lawn
mower or side of engine.
5. Slowly pour oil down the oil fill spout,
stopping every few ounces to check the
oil level with the dipstick.
6. Stop adding oil when you reach the
FULL mark on the dipstick. Wait a
13 minute to allow oil to settle.
