CUTTING

BLADE

When

removing

the

cutting

blade

for

sharpening

or

replacement,

protect

hands

by

using

heavy

gloves

or

a

to

grasp

the

cutting

blade.

Remove

the

bolt

and

bell

washer

which

hold

the

blade

and

adapter

to

the

engine

crankshaft.

Remove

the

blade

and

adapter

from

the

crankshaft.

If

the

blade

or

blade

adapter

needs

replacing,

remove

the

two

small

bolts,

lock

washers

and

nuts

which

A

WARNING:

Periodically

inspect

the

blade

for

cracks,

especially

if

you

strike

a

foreign

object.

Replace

when

necessary.

When

sharpening

the

blade,

follow

the

original

angle

of

grind

as

a

guide.

It

is

extremely

important

that

each

cutting

edge

receives

an

equal

amount

of

grinding

to

prevent

an

unbalanced

blade.

An

unbalanced

blade

will

cause

excessive

vibration

when

rotating

at

high

speeds,

may

cause

damage

to

the

mower

and

could

break,

causing

personal

injury.

It

is

recommended

that

the

blade

always

be

removed

from

the

adapter

for

the

best

test

of

balance.

The

blade

can

be

tested

by

balancing

it

on

a

round

shaft

screwdriver.

Remove

metal

from

the

heavy

side

until

it

balances

evenly.

Before

reassembling

the
