Craftsman 536.88123 - Manual (Page 17)

LUBRICATION
• Hex Shaft and Gears - Hex shaft and
gears require no lubrication. All bearings
and bushings are lifetime lubricated and
require no maintenance.
NOTE: Any greasing or oiling of the above
components can cause contamination of
the friction wheel. If the disc drive plate or
friction wheel comes in contact with grease
or oil, damage to the friction wheel will re­
sult.
Should grease or oil come in contact with
the disc drive plate or friction wheel, be sure
to clean the plate and wheel thoroughly.
NOTE: For storage, the hex shaft and
gears should be wiped with 5W-30 motor oil
to prevent rusting. See second figure on
page 16.
• Auger Gear Box - The auger gear box is
lubricated at the factory and should not
require additional lubrication. If for some
reason the lubricant should leak out, or if
the auger gear box has been serviced,
add Lubripiate No. 630-AA or equivalent.
Maximum 3-1/4 ounces should be used.
Remove filler plug as seen in figure below
once a year. If grease is visible, do not
add. If grease is not visible, use a piece
of fine wire like a dipstick, to check if
there is grease in the gearbox. Add
grease if necessary. Reinstall gear box
filler.
OIL RECOMMENDATION
Only use high quality detergent oil rated
with API service classification SG. Select
the oil's viscosity grade according to your
expected operating temperature:
NOTE: For extreme cold operating condi­
tions of 0° and below, use a partial synthetic
0W30 motor oil for easier starting.
Change the oil every twenty-five (25) hours
thereafter, and at the beginning of each
season.
• Position the snow thrower so that the oil
drain plug is at the lowest point on the
engine. Remove the oil drain plug and
the oil fill cap/dipstick. Drain the oil into a
suitable container. Oil will drain more
freely when warm.
• Replace the oil drain plug and tighten se­
curely.
SPARK PLUG
• Make sure that the spark plug is tight­
ened securely into the engine and the
spark plug wire is attached to the spark
plug.
• If a torque wrench is available, torque
plug to 18 to 23 foot pounds.
• Clean the area around the spark plug
base before removal to prevent dirt from
entering the engine.
• Clean the spark plug and reset the gap
periodically at .030 inch.
LUBRICATION
Check the crankcase oil level (see figure be­
low) before starting the engine and after
each five (5) hours of continuous use. Add
S.A.E. 5W30 motor oil as needed. Tighten
fill cap/dipstick securely each time you
check the oil level.
NOTE: Oil level must be
between full and add mark
