SECTION 5: OPERATING YOUR LAWN MOWER
Towards Better Mower Performance
1. Pour fresh, clean gasoline into the mowers gas tank until the tank is full. Do not use gasoline that is more than 30 days old.
2. Make sure to connect the mowers spark plug wire before trying to start the engine.
3. 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.
4. 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.
WARNING: Keep hands and feet away from chute area on the cutting deck. The operation of any lawn mower can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields.
NOTE: For shipping pur poses 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.
5. Hold control handle down and pull rope firmly to start the engine.
6. 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.
7. To mulch insert the mulch plug/cover on the mower.
8. Before storing the lawn mower for the winter, use stabilizer-treated fuel and run the tank dry.
9. Thirty days before start of the new season, check the air filter, spark plug and blade on the lawn mower, and replace if needed.
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.
Before Starting Your Mower
Check for proper clutch operation by performing the following procedure before starting the engine.
9
With the drive clutch released, push mower forward. It should move freely. Pull mower backward. It should move with only a small amount of resistance.
If the rear wheels tend to lock up, the clutch may not be releasing completely. Do not start the engine until corrections have been made.
Check the drive cable for severe bends, kinks, or binding. Also check for grass build-up around the belt.
If drive clutch control needs adjustment see the Adjustment Section.
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 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.
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: Always stop engine, discon­nect spark plug, and ground against engine before performing adjustments.
Cutting Height Adjustment
Each wheel has a height adjustment lever which provides cutting height adjustment. When the adjustment lever is moved from one location to another the height of cut will be changed. Simply depress the lever towards wheel and move lever assembly to desired position. See Figure 9.
IMPORT ANT :
relative position. For rough or uneven lawns, move the height adjustment lever to a higher position. This will help stop scalping of the grass.
All wheels must be placed in the same
Height Adjustment Levers

Handle Height Adjustment
Your mower is shipped with the handle in the higher height position. To lower the height proceed as follows:
Remove the start er ro pe fr om the rope g uide .
Disconnect the handle from the handle bracket
assemblies by removing the wing nuts. See Figure 10.

If this debris is allowed to accumulate, it will invite rust and corrosion, and may prevent proper mulching, discharge, or bagging. The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug wire is disconnected).

WARNING: Periodical ly inspect the blade adapter for cracks , espec ially if yo u st rike a foreign object. Replace when necessary.
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.
12
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 reinstalling 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 end tips facing up or 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.
If unit is tipped for easier access to belt, tip the mower back on its side with the air filter side away from the ground.
To get easier access to the belt, just securely place the mower on ra ised bl ocks.
Remove the transm ission cove r by sli ding off th e two plastic rivets with a screwdriver on each side of cover. See Figure 13.
