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 manufac-
turer approved replacement catcher.
Give the lawn mower model number
when ordering.

LUBRICATION
Use only high quality detergent oil rated
with API service classification SF-SJ.
Select the oil's SAE viscosity grade
according to your expected operating
temperature.
SAEVISCOSITYGP, AOE$
NOTE: Although multi-viecosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, these multi-viscosity oits
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
operation or at least once a year if the
lawn mower is not used for 25 hours in
one year.
