MAINTENANCE
SERVICE and ADJUSTMENTS
7
Before each mowing session unplug the mower and ensure that the blade
has stopped. Check all nuts, bolts and screws to ensure proper tightness,
Be sure to check the blade fastening system.
IMPORTANT:
To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment (including brush inspection and replacement)
should be performed by SEARS Service Centres or other qualified service
organizations, always using Sears replacement parts. When servicing use
ONLY IDENTICAL REPLACEMENT PARTS
.
Inspect and thoroughly clean your mower at the beginning of each mowing
season for longer life and better performance.
From time to time turn the mower off and wait for the blade to stop. Then
unplug the power cord and turn the mower on its side. Using an object such
as a stick or rag, wipe out any accumulation of grass in the blade area. Also
clean out any grass or debris which may be packed around the
discharge/mulch door area. Be careful of the sharp edges of the blade.
