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:

• Step back from the mower to fully extend your arms.

• Be sure you are well balanced with sure footing.

• Pull the mower back slowly, no more than half way toward you.

• Repeat these steps as needed.

• Do not operate the mower while under the influence of alcohol or drugs.

• Do not engage the self-propelled mechanism on units so equipped while starting engine.

• The blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The blade control handle must operate easily in both directions and automatically return to the disengaged position when released.

• Never operate the mower in wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. Keep a firm hold on the handle and walk, never run. If you feel you are losing your footing, RELEASE THE BLADE CONTROL HANDLE IMMEDIATELY and the blade will stop rotating within three seconds.

• Mow only in daylight or good artificial light.

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

• If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

• Shut the engine off and wait until the blade comes to a complete stop before removing the grass catcher or unclogging the chute. The cutting blade continues to rotate for a few seconds after the engine is shut off. Never place any part of the body in the blade area until you are sure the blade has stopped rotatin g.

• Never operate mower without proper guards, grass catcher, plates or other safety protective devices in place.

• Muffler and engine become hot and can cause a burn. Do not touch.

Using Y our Lawn Mow er

Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage the lawn mower or the engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal 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.

WARNING: Periodical ly inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.

• Remove the center bolt which secures the blade to the crankshaft followed by blade bell support, blade, and blade adapter.

• Move the cutting height adjustment to the highest position.

• Remove the three hex screws holding the baffle to the deck and pivot baffle towards the rear of the mower. See Figure 18.

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. It may cause damage to the mower, and could break causing personal injury.

The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter when testing for balance. Before installing the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade adapter with light oil.

• 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.

• Slide the blade adapter onto the engine crankshaft.

• Place the blade on the adapter. Be certain the

blade is aligned and seated on the blade adapter flanges.

• Place blade bell support on blade. Make sure the notches on the blade bell support are aligned with small holes in the blade.

• Replace hex bolt and tighten hex bolt to torque: 450 in. lbs. min., 600 in. lbs. max.

NOTE: To ensure safe operation of your mower, the blade bolt must be checked periodically for correct torque.

Drive Belt Removal and Replacement

• Disconnect the spark plug wire and ground it against the engine.

• Drain the fuel tank or place a piece of plastic beneath the cap to prevent gasoline leakage.

• Place shift lever in the first position and tip the mower on its side.
