TO START ENGINE

  • To start a cold engine, push primer five (5) 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.
  • Push engine speed control lever to fast ( )position.
  • 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, 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.
  • For extremely heavy cutting, red cue 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.
  • When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher. Reduce ground speed (pushing speed) and/or run the lawn mower over the area a second time.
  • If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass.
  • 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 airflow and extend engine life.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE “CLEANING” IN CUSTOMER RESPONSIBILITIES SECTION OF THIS MANUAL.

  • The special mulching blade will recut the grass clip- pings many times and reduce ther in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients 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 it is wet. 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 (See Fig. 11). lf 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 clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly.
  • Certain types of grass and grass conditions may re- quire that an area be mulched a second time to completely hide the clippings. When doing a second cul, 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.

CUSTOME RESPOILITIES

CRAFTSMAN 917.372851 Convertible Walk Behind Mower -
Fig11

  1. Change more often when operating under a heavy load or in high ambient temperatures.
  2.  Service more often when operating in dirty or dusty conditions.
  3. Replace blades more often when mowing in sandy soil.

GENERAL RECOMMENDATIONS
The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain mower as instructed in this manual.
Some adjustments will need to be made periodically to properly maintain your unit.
All adjustments in the Service and Adjustments section of this manual should be checked at least once each season.

  • Once a year, replace the spark plug, replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assures proper air-fuel mixture and helps your engine run better and last longer.
  • Follow the maintenance schedule in this manual.

BEFORE EACH USE

  • Check engine oil level.
  • Check for loose fasteners.

LUBRMCATON
Keep unit well lubricated (See “LUBRICATION CHART”).
LUBRICATION CHART

Replace bent or damaged blades.
TO REMOVE BLADE (See Fig. 12)

  • Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.
  • Turn lawn mower on its side. Make sure air filter and carburetor are up.
  • Use a wood block between blade and mower housing to prevent blade from turning when removing blade bolt.
  • Protect your hands with gloves and/or wrap blade with heavy cloth.
  • Remove blade bolt by turning counter-clockwise.
  • Remove blade and attaching hardware (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 condition to work properly. Replace adapter if damaged.

  • Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft.
  • 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.
NOTE: We do not recommend sharpening blade – but if you do, be sure the blade is balanced.
TO SHARPEN BLADE
Care should be taken to keep the blade balanced. An unbalanced blade will cause eventuate damage to tawny 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, drive 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.

GEAR CASE

  • To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.
  • The gear case is filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case,
  • If lubricant is required, use only Texaco Staple Premium Grease, part no, 750355. Do not substitute.

DRIVE WHEELS
Check front drive wheels each time before you mow to be sure they move freely.
The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels.
If necessary to clean the drive wheels check both front wheels.

  • Remove hubcaps, hairpin cotters and washers.
  • Remove wheels from wheel! adjusters.
  • Remove any trash or grass cuttings from inside the dust cover, pinion and/or drive wheel gear teeth.

STORAGE

immediately prepare your fawn mower for storage at the end of the season or if the unit will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area,

  • Clean entire lawn mower (See “CLEANING” in the Customer Responsibilities section of this manual).
  • Lubricate as shown in the Customer Responsibilities section of this manual.
  • Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.
  • Touch up all rusted or chipped paint surfaces; sand lightly before painting.

HANDLE (See Fig. 19)
You can fold your lawn mower handle for storage.

  • Squeeze the bottom ends of the lower handle toward each other until the lower handle clears the handle bracket, then move handle forward.
  • Loosen upper handle mounting bolts enough to allow upper handle to be folded back.

IMPORTANT: WHEN FOLDING THE HANDLE FOR STORAGE OR TRANSPORTATION, BE SURE TO FOLD THE HANDLE AS SHOWN OR YOU MAY DAMAGE THE CONTROL CABLES.

  • When setting up your handle from the storage position, the lower handle will automatically lock into the mowing position.

ENGINE FUEL SYSTEM

IMPORTANT:
IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING TN ESSENTIAL FUEL SYSTEM PARTS SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT 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.

  • Drain the fuel tank.
  • Start the engine and let it run until the fuel lines and carburetor are empty.
  • Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur,
  • Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container, Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer,
ENGINE OiL
Drain oil (with engine warm) and replace with clean engine oil. (See “ENGINE” in the Customer Responsibilities section of this manual).
CYLINDER

  • Remove spark plug,
  • Pour one ounce (29 ml) of oil through spark plug hole into cylinder.
  • Pull starter handle slowly a few times to distribute oil
  • Replace with new spark plug.

OTHER

  • Do not store gasoline from one season to another.
  • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems.
  • If possible, store your unit indoors and cover it to give protection from dust and dirt.
  • Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust.

IMPORTANT: NEVER COVER MOWER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
CAUTION: Never store the lawn mower with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool befor storing in any enclosure.
