LUBRICATION
Mandrels are shipped lubricated, however we suggest each
mandrel be rechecked by applying grease.
Each mandrel should be filled with grease thru the Grease
Fitting located between mower blade and underside of the
mower housing (Fig. 11 A). Wipe fitting clean before greasing.
Use high performance, extreme pressure lubricating grease.
(Amdex No. 1 EP or equivalent). Add grease until it oozes
out around the cap above the blade and under the sheave.
This will not damage the grease retainer. Wipe mandrel clean
of excess grease. Under normal usage the mandrels should re·
quire lu brication only once each season. Beyond normal usage
the mandrels may require lubrication more often. This grease
may be obtained by ordering thru your nearest Sears repair
parts depart ment. Part No. 2557R.
Reattach spark plug wire(sl to spark plug(s) .
