Craftsman 917.275685 Owner's Manual page 19

• 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, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone balancer,
follow the instructions supplied with
balancer.)
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 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.

BATTERY
Your tractor has a battery charging system
which is sufficient for normal use. How-
ever, periodic charging of the battery with
an automotive charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• Keep small vent holes open.
• Recharge at 6-10 amperes for 1 hour.
NOTE: The original equipment battery on
your tractor is maintenance free. Do not
attempt to open or remove caps or covers.
Adding or checking level of electrolyte is
not necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and termi-
nals can cause the battery to "leak" power.
1. Remove terminal guard.
2. Disconnect BLACK battery cable first
then RED battery cable and remove
battery from tractor.
3. Rinse the battery with plain water and
dry.
4. Clean terminals and battery cable ends
with wire brush until bright.
5. Coat terminals with grease or petro-
leum jelly.
6. Reinstall battery (See "REPLACING
BATTERY" in the SERVICE AND AD-
JUSTMENTS section of this manual).
TRANSAXLE COOLING
The transmission fan and cooling fins
should be kept clean to assure proper
cooling.
Do not attempt to clean fan or transmis-
sion while engine is running or while the
transmission is hot. To prevent possible
damage to seals, do not use high pres-
sure water or steam to clean transaxle.
• Inspect cooling fan to be sure fan
blades are intact and clean.
• Inspect cooling fins for dirt, grass clip-
pings and other materials. To prevent
damage to seals, do not use com-
pressed air or high pressure sprayer to
clean cooling fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory
and fluid maintenance is not required for
the life of the transaxle. Should the trans-
axle ever leak or require servicing, contact
a Sears or other qualified service center.
V-BELTS
Check V-belts for deterioration and wear
after 100 hours of operation and replace
if necessary. The belts are not adjustable.
Replace belts if they begin to slip from wear.
ENGINE
LUBRICATION
Only use 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
C -3o .20 to o 10 2o
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, they will result in increased
oil consumption when used above 32°F.
Check your engine oil level more frequent-
ly to avoid possible engine damage from
running low on oil.
Change the oil after every 50 hours of op-
eration or at least once a year if the tractor
is not used for 50 hours in one year.
Check the crankcase oil level before start-
ing the engine and after each eight (8)
hours of operation. Tighten oil fill cap/
dipstick securely each time you check the
oil level.
