ENGINE STORAGE
If engine will be unused for 30 days or
more, prepare it for storage by following
the recommended procedures found in
the Engine Owner’s Manual.
MOWER SERVICE
The following maintenance/repair proce-
dures can be performed by either the
owner or an authorized service dealer.
See an authorized service dealer for
complete mower service.
TIPPING MOWER FOR SERVICE
When servicing the underside of the
mower for any reason, the mower
should only be tipped backward on its
rear wheels (and securely propped up to
prevent it from falling). Tipping the
mower forward or to either side could
result in damage to engine.
TIP: Before tipping mower, install a
small plastic sandwich style bag under
the gas cap and tighten securely. This
will virtually eliminate any fuel weepage
from the cap.
Be sure to remove the
plastic bag before re-using mower.
BELT COVER REMOVAL
The belt cover must be removed to per-
form several maintenance procedures.
To Remove Belt Cover:
1. Stop engine, wait for all parts to
stop moving, and disconnect spark
plug wire.
2.
Remove four screws (R, Figure 5-5)
and remove cover.
To Reinstall Belt Cover:
1.
Position belt cover in place.
2.
Secure with the four screws removed
earlier.
BLADE SPINDLE BELT
REPLACEMENT

place the blade spindle drive belt (re-
