BLADES

A.

Removal

for

Sharpening

or

Replacement

WARNING:

Be

sure

to

disconnect

and

ground

the

spark

plug

wire

and

remove

ignition

key

before

working

on

the

cutting

blade

to

prevent

accidental

engine

start¬

ing.

Protect

hands

by

using

heavy

gloves

or

a

rag

to

grasp

the

cutting

blades.

1.

Remove

the

large

bolt

and

lock

washer

which

holds

the

blade

and

adapter

to

the

blade

spindle.

2.

Remove

the

blade

and

adapter

from

the

spindle.

3.

If

the

blade

or

blade

adapter

needs

replacing,

remove

the

two

small

bolts,

lock

washers

and

nuts

which

hold

the

blade

to

the

adapter.

B.

Sharpening

Remove

the

cutting

blades

by

following

the

directions

of

the

preceding

section.

When

sharpening

the

blades,

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.

The

blade

can

be

tested

for

balance

by

balancing

it

on

a

round

shaft

screwdriver.

Remove

metal

from

the

heavy

side

until

it

balances

evenly.

NOTE:

It

is

recommended

that

the

blade

always

be

removed

from

the

adapter

for

the

best

test

of

balance.

C.

Reassembly

Before

reassembling

the

blade

and

the

blade

adapter

to

the

unit,

lubricate

the

spindle

and

the

inner

surface

of

the

blade

adapter

with

light

oil.

Lubricating

the

bolt

holes,

bolts

and

inner

surface

of

the

nuts

with

light

oil

is

also

recommended.

Engine

oil

may

also

be

used.

When

replacing

blades,

be

sure

to

install

the

blade

with

the

side

of

the

blade

marked

“Bottom”

(or

with

part

number)

facing

the

ground

when

the

mower

is

in

the

operating

position.
