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. 11A). Wipe fitting clean before greasing.

Use

high performance, e

xtreme

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 lubrication

after

every

50

hours

of

operation

and

at

the

beginning

of

each

new

season. This grease may be

obtained

by

ordering

thru

your

nearest Sears repair parts

department.
