CHECKING

THE OIL LEVEL

--

i

[_

WARNING:

To avoid serious

personal

injury, always

turn

your

unit off and

allow it to cool

before

you clean or service

it.

The importance

of checking

and

maintaining

the

proper

oil level in the

crankcase

cannot

be overemphasized.

Check

oil before

each

use:

1.

Stop

the

engine

and

allow

oil to drain

into the

crankcase.

2.

Place the engine on a flat,

level surface with

the

cutting

head shield

f

hanging

off a work bench

or table to get a proper

oil

level reading (Fig. 17).

3.

Keep dirt, grass clippings

and other debris out of the

engine. Clean the area

around the oil fill plug

before removing

it.

4.

Remove the oil fill plug.

5.

Look into the oil fill hole;

use a flashlight

if needed.

The oil should

be just

touching

the inner most

thread (Fig. 18).

6.

If the oil level is not

touching the inner most

thread on the oil fill hole,

add a small amount of oil to

the oil fill hole and recheck

(Fig. 18). Repeat this

procedure until the oil level

reaches the

innermost

O=Ring

thread on the oil fill hole.

NOTE:

Do not overfill the unit.

AUTION:

Wear gloves

to prevent injury when handling

the unit.

For a new engine, change the

?<:Z

oil after the first 10 hours

of

operation.

Change

the oil

while the engine

is still warm.

The oil will flow freely and

carry away more impurities.

1.

Remove the oil fill plug.

2.

Pour the oil out of the oil

fill hole and into a

container

by tipping

the

Fig. 20

unit to a vertical

position

(Fig. 20). Allow

ample

time for complete

drainage.

3.

Wipe up any oil residue

on the unit and clean up

any oil that may have

spilled.

Dispose

of the oil

according

to Federal,

State and local

Fig. 21

regulations.

4,

Refill the crankcase

with 3.04 fluid ounce (90 ml) of SAE 30 SF,

SG, SH oil.

NOTE:

Use the bottle and

spout saved from

initial use to measure

the correct

amount

of

oil. The top of the

Fill Line

label on the bottle

measures

approximately

3.04

ounces

(90 ml) (Fig.

22). Check the level,

Fig. 22

See Checking

the Oil

Level. If the level is low, add a small amount

of oil and

recheck.

Do not overfill (Fig. 21).

5.

Replace the oil fill plug.

6.

Reconnect

the spark

plug boot.

AIR FILTER MAINTENANCE

the unit off and allow it to cool before you clean or service it.

Cleaning

the Air

Filter

Air Filter Cover

Clean and re-oil the air filter

every 10 hours of operation.

It
