Yard-Man 13875-9 - Maintenance; Air Cleaner

7. It is a good Idea to have an extra set of blades
on hand. This wilt allow you to use the mower
while one set is being sharpened. Always
have the blades sharpened by a qualified
service center with proper balancing equip¬
ment. For blade replacement use only the
authorized original blade, see the parts list for
the correct part number.
8. Where grass has been trampled, it is a good
idea to rake such areas before mowing. This
will make the grass stand up for a better cut.
9. If you try to cut too close to small trees the
mower can scrape or cut into the tree bark,
causing damage. It is better to adopt a policy
of cutting reasonably close to such objects
and clipping close with hand clippers.

MAINTENANCE
Your new rider will give excellent service for many
years if given reasonable care and maintenance,
as follows:
1. C h e ck the oil level in the crankcase fre¬
quently, at least every 5 hours of operation.
When checking oil level be sure the area
around the oil fill cap is cleaned of all debris
before it is removed. Otherwise debris can fall
into the crankcase and cause damage,
Change oil every 25 hours of operation...
more frequently if operated under dusty
conditions.
On new engines, it is important that the oil be
changed after the first few hours of operation.
Change between the first 2-5 hours of
operation.
For the proper grade and weight of oil to use, see
BEFORE STARTING ENGINE, page 8.
