GENERAL OPERA TION

• Read this operator’s manual carefully in its entirety

before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manual(s) before operation. Be completely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacemen t parts.

• Your rotary mower is a precision piece of power

equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to mow grass. Do not use it for any other purpose.

• Never allow children under 14 years old to operate a

power mower . Childr en 14 year s old an d over s hould only operate mower under close parental supervision. Only responsible individuals who are familiar with these rules of safe operation should be allowed to use your mower.

• Keep the area of operation clear of all persons,

particularly small children and pets. Stop engine when they are in the vicinity of your mower to help prevent blade contact or thrown object injury. Although the area of operation should be completely cleared of foreign objects, an object may have been overlooked and could be accidentally thrown by the mower in any direction and cause serious personal injury to the operator or any others allowed in the area.

• Wear sturdy, rough-soled work shoes and close-fitting

slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Do not wear loose fitting clothes or jewelry. They can be caught in moving parts. Never operate a unit in bare feet, sandals, slippery or light weight (e.g. canvas) shoes.

• Always wear safety glasses or safety goggles during

operation or while performing an adjustment or repair, to protect eyes from foreign objects that may be thrown from the machine in any direction.

• Thoroug hly inspect the ar ea where the equipm ent is to be used. Remove all stones, sticks, wire, bones, toys and other foreign objects which could be picked up and thrown by the mower in any direction and cause serious personal injury to the operator or any others allowed in the area. Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. To help avoid a thrown objects injury, keep children, bystanders and helpers at least 75 feet from the mower while it is in operation.

• Do not put hands or feet near or under rotating parts. Keep clear of discharge opening at all times as the rotating blade can cause injury.

• Many injuries occur as a result of the mower being pulled over the foot during a fall. Do not hang on to the mower if you are falling; release the handle immediately.

• Never pull the mower toward you while you are walking. If you must back the mower away from a wall or obstruction first look down and behind, and then follow these steps:

NOTE: For shipping p urposes your mower is set with

the wheels in a low cutting height position. For best results raise the cutting position until it is determine which height is best for your lawn. See the Adjustment Section for details.

Gas and Oil Fill-Up

Service the engine with gasoline and oil as instructed in the separ ate eng ine m anua l pack ed wi th your mowe r. Read instructions care fully.

WARNING: Never fill fuel tank indoors with engine running or until the engine has been allowed to cool for at least two minutes after running.

Towards Better Mower Performance

1. Read this manual in its entirety before you start the lawn mower. Instructions given here have been designed for maintaining safety while getting the best performance from your mower. Follow the instructions closely.

2. Pour fresh, clean gasoline into the mower’s gas tank until the tank is full. Do not use gasoline that is more than 30 days old.

3. Always use a fuel stabilizer. It will double the life of the gasoline used.

4. Make sure to connect the mower’s spark plug wire before trying to start the engine.

5. Add engine oil to the oil fill on the mower engine. Check the dipstick and add more if necessary. Remember that the oil level has to touch the fill line.

6. Locate the primer decal near the primer bulb on the engine, and read its instruction. Using your thumb, press the primer bulb slowly as many times as the deca l advises.

For more details about proper lawn care, visit our website at www.mtdproducts.com/machines/tips

7. Hold control handle down and pull rope firmly to start the engine.

8. Set cutting height adjustment lever to middle setting and mow a single pass on your lawn; then adjust to desired height for a closer cut.

9. When bagging the grass clippings, remove mulch plug/cover and store.

10. To mulch insert the mulch plug/cover on the mower.

11. In heavy growing season, it may be necessary to mow lawn twice weekly. Clumps of grass clippings left behind on the lawn usually means that the grass is too high to mulch.

12. Before storing the lawn mower for the winter, use stabilizer-treated fuel and run the tank dry.

13. Thirty days before start of the new season, check the air filter, spark plug and blade on the lawn mower, and replace if needed.

Starting Engine

• Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug is fastened securely over the metal tip on the spark plug.

• Prime engine as instructed in the separate engine manual packed with your unit.

• Your lawn mower may be equipped with a constant speed throttle, which is set at full throttle for best performance.

• Stand behind the mower and squeeze the blade control handle against the upper handle.

• Grasp recoil starter handle and pull rope out slowly until engine reaches the start of compression cycle (rope will pull slightly harder at this point). Let the rope rewind slowly. Pull rope with a rapid, continuous, full arm stroke. Keeping a firm grip on the starter handle, let the rope return to the starter slowly.

Using Y our Lawn Mow er

Be sure that the lawn is clear of stones, sticks, wire, or other obj ects wh ich could d amage the la wn mo wer or the engine. Such objects could be accidently thrown by the mower in any di rection and cause serious pers onal injury to the operator and others.

For best results, do not cut wet grass because it tends to stick to the underside of the mower, preventing proper discharge of grass clippings, and could cause

you to slip and fall. New grass, thick grass, or wet grass may require a narrower cut.

For a healthier lawn, never cut off more than one-third of the total length of the grass. Your lawn should be cut in the fall as long as there is growth. This mower is designed to be operated at full throttle to give you the best cut and do the most effective job of mowing or mulching.

WARNING: If you strike a foreign object, stop the engine. Remove wire from the spark plug, thoroughly inspect the mower for any damage, and repair the damage before restarting and operating the mower. Extensive vibration of the mower during operation is an indication of damage. The unit should be promptly inspected and repaired.

Mulching

For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck, preventing proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow in excess of 4”, mulching is not recommended. Mow using the side discharge to reduce the grass height to 3 1/4” maximum before mulching.

SECTION 6: MAKING ADJUSTMENTS

WARNING: Do not at any time make any adjustments without first stopping engine and disconnecting spark plug wire.

Cutting Height Adjustment

Height Adjustment Lever
