I. GENERAL OPERATION

• Read, understand, and follow all instructions on the machine and in the

manual(s) before starting. Be thor- oughly familiar with the controls and the proper use of the machine before

starting.

• Do not put hands or feet near or under rotating parts. Keep clear of the

discharge opening at all times.

• Only allow responsible individuals, who are familiar with the instructions, to

operate the machine.

• Clear the area of objects such as

rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the blade.

• Be sure the area is clear of other

people before mowing. Stop machine if anyone enters the area.

• Do not operate the mower when

barefoot or wearing open sandals. Always wear substantial foot wear.

• Do not pull mower backwards unless absolutely necessary. Always look

down and behind before and while

moving backwards.

• Do not operate the mower without

proper guards, plates, grass catcher or

other safety protective devices in place.

• See manufacturer's instructions for

proper operation and installation of

accessories. Only use accessories approved by the manufacturer.

• Stop the blade(s) when crossing gravel drives, walks, or roads.

• Stop the engine (motor) whenever you

leave the equipment, before cleaning

the mower or unclogging the chute.

• Shut the engine (motor) off and wait

until the blade comes to complete stop

before removing grass catcher.

• Mow only in daylight or good artificial

light.

• Do not operate the machine while

under the influence of alcohol or drugs.

• Never operate machine in wet grass. Always be sure of your footing: keep a

firm hold on the handle and walk; never run.

• Disengage the self-propelled mecha-

nism or drive clutch on mowers so equipped before starting the engine

(motor).

• If the equipment should start to vibrate

abnormally, stop the engine (motor) and check immediately for the cause.

Vibration is generally a warning of trouble.

• Always wear safety goggles or safety

glasses with side shields when operat- ing mower.

II. SLOPE OPERATION Slopes are a major factor related to slip

and fall accidents which can result in severe injury. All slopes require extra

caution, if you feel uneasy on a slope, do not mow it.

DO:

• Mow across the face of slopes: never up and down. Exercise extreme caution

when changing direction on slopes.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

DO NOT:

• Do not trim near drop-offs, ditches or embankments. The operator could lose

footing or balance.

• Do not trim excessively steep slopes.

• Do not mow on wet grass. Reduced footing could cause slipping.

III. CHILDREN

Tragic accidents can occur if the operator

is not alert to the presence of children. Children are often attracted to the

machine and the mowing activity. Never assume that children will remain where

you last saw them.

• Keep children out of the trimming area and under the watchful care of another

responsible adult.

• Be alert and turn machine off if children enter the area.

• Before and while walking backwards, look behind and down for small

children.

• Never allow children to operate the machine.

° Use extra care when approaching blind

corners, shrubs, trees, or other objects that may obscure vision.

BEFORE STARTING ENGINE

ADD OIL Your lawnmower is shipped without oil in

the engine. For type and grade of oil to

use, see "ENGINE" in the Maintenance

section of this manual. A CAUTION: DO NOT overfill engine with

oil, or it will smoke on startup.

1. Be sure lawnmower is level and area

around oil fig is clean.

2. Remove oil dipstick from oil fill spout. Make sure that rim of spout is clean.

3. You receive a container of oil with the unit. Slowly pour 3/4 (15 oz.) of the oil

from the container down the oil fill spout into the engine.

4. Wait one minute to allow oil to settle. Insert and tighten dipstick, then

remove it to check oil level.

5. Continue adding small amounts of oil and rechecking the dipstick until it

reads full. DO NOT overfill, or engine will smoke on startup.

6. Always be sure to retighten oil dipstick

before starting engine.

• Check oil level before each use. Add

oil if needed. Fill to full line on dipstick.

• Change the oil after every 25 hours of

operation or each season. You may

need to change the oil more often under dusty, dirty conditions.

ADD GASOLINE

• Fill fuel tank to bottom of tank filler

neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a

minimum of 87 octane. Do not mix oil

with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness.

A CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline

near an open flame. A CAUTION: Alcohol blended fuels

(called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can

damage the fuel system of an engine while in storage. To avoid engine

problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the

engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel

next season. See Storage Instructions for additional information. Never use engine

or carburetor cleaner products in the fuel tank or permanent damage may occur.

TO START ENGINE

NOTE: Due to protective coatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal.

1. To start a cold engine, push primer three (3) times before trying to start.

Use a firm push. This step is not

usually necessary when starting an

engine which has already run for a

few minutes.

2. Hold operator presence control bar down to the handle and pull starter

handle quickly. Do not allow starter rope to snap back.

TO STOP ENGINE

• To stop engine, release operator

presence control bar.

NOTE: In cooler weather it may be necessary to repeat priming steps. In

warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes

before attempting to start and do not repeat priming steps.

MOWING TiPS

• Under certain conditions, such as very

tall grass, it may be necessary to raise

the height of cut to reduce pushing effort and to keep from overloading the

engine and leaving clumps of grass

clippings. It may also be necessary to

reduce ground speed and/or run the lawn mower over the area a second

time.

• For extremely heavy cutting, reduce the width of cut by overlapping previously

cut path and mow slowly.

• For better grass bagging and most

cutting conditions, the engine speed should be set in the FAST position.

• For side discharge lawn mowers, cutting in a counter-clockwise direction,

starting at the outside of the area to be

cut, spreads grass clippings more evenly and puts less load on the

engine. To keep clippings off of walkways, flower beds, etc., make the

first cuts in a clockwise direction.

• Pores in cloth grass catchers can become filled with dirt and dust with

use and catchers will collect less grass. To prevent this, regularly hose catcher

off with water and let dry before using.

• Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and

extend engine life.

MULCHING MOWING TIPS

IMPORTANT: For best performance, keep mower housing free of built-up grass and

trash. See "CLEANING" inthe Maintenance section of this manual.

• The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the

lawn they will disperse intothe g_ss and not be noticed. ALso, the mulched grass

will biodegrade quickly to provide nubients for the lawn. Always mulch with your

highest engine (blade) speed as this will provide the best recutting action of the

blades.

• Avoid cutting your lawn when itiswet Wet

grass tends to form clumps and interferes with the mulching action. The best time to

mow your lawn is the early afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct

sun.

• For best results, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass

blades. If the lawn is overgrown it will be necessary to raise the height of cut to

reduce pushing effort and to keep from

overloading the engine and leaving dumps of mulched grass. For exlzemely

heavy grass, reduce your width of cut by overlapping previously cut path and mow

slowly.

MAX 1/3

• Certain types of grass and grass condi- tions may require that an area be mulched a second time to completely hide the

clippings. When doing a second cut, mow

across or perpendicular to the first cut path.

• Change your cutting pattern from week to week. Mow north to south one week then

change to east to west the next week. This will help prevent matting and graining of

the lawn.

• Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause

tire damage.

BLADE CARE For best results, mower blade must be

kept sharp. Replace bent or damaged

blades. TO REMOVE BLADE

1. Disconnect spark plug wire from spark plug and place wire where it cannot

come in contact with spark plug.

2. Turn lawn mower on its side. Make sure air filter and carburetor are up.

3. Use a wood block between blade and

mower housing to prevent blade from

turning when removing blade bolt.

NOTE" Protect your hands with gloves and/or wrap blade with heavy cloth.

4. Remove blade bolt by tuming counter- clockwise.

5. Remove blade and attaching hard- ware (bolt, lock washer and hardened washer).

NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condi-

tion to work properly. Replace adapter if damaged.

TO REPLACE BLADE

1. Position the blade adapter on the engine crankshaft. Be sure key in

adapter and crankshaft keyway are aligned.

2. Position blade on the blade adapter aligning the two (2) holes in the blade

with the raised lugs on the adapter.

3. Be sure the trailing edge of blade

(opposite sharp edge) is up toward

the engine.

4. Install the blade bolt with the lock washer and hardened washer into

blade adapter and crankshaft.

5. Use block of wood between blade and

lawn mower housing and tighten the blade bolt, turning clockwise.

• The recommended tightening torque is

35-40 ft. Ibs.

IMPORTANT: Blade bolt is grade 8 heat treated.

TO SHARPEN BLADE NOTE: We do not recommend sharpen-

ing blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will

cause eventual damage to lawn mower or engine.

• The blade can be sharpened with a file

or on a grinding wheel. Do not attempt

to sharpen while on the mower.

• To check blade balance, ddve a nail

into a beam or wall. Leave about one inch of the straight nail exposed. Place

center hole of blade over the head of

the nail. If blade is balanced, it should

remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade

is balanced.

mower or side of engine.

5. Fill engine with oil. (See "ADD OIL" in

the Operation section of this manual).

6. Reconnect spark plug wire to spark plug.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption

when used above 32°1=. Check your engine oil level more frequently to avoid possible engine damage from running

low on oil.

Change the oil after every 25 hours of operation orat least once a year if the

lawn mower is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine and after each five (5)

hours of continuous use. 33ghten oil plug securely each time you check the oil

level.
