GENERAL RECOMMENDATIONS LAWN MOWER

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 unit as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual.

•At least once a year, replace the spark plug, clean or replace air fi lter element and check blade for wear. A new spark plug and clean/new air fi lter element assure proper air-fuel mixture and help 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.

LUBRICATION

Keep unit well lubricated

(See “LUBRICATION CHART”).

LUBRICATION CHART

➀ Wheel adjuster (on each wheel)

➁ Engine oil

➀ Mulcher door hinge pin

➀ Rear door hinge

➀ Handle bracket mounting pins

➀ Spray lubricant

➁ See "ENGINE" in Maintenance section.

IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract dust and dirt that will shorten the life of the self-lubricating bearings. If you feel they must be lubricated, use only a dry, powdered graphite type lubricant sparingly.

Always observe safety rules when per- forming any maintenance.

TIRES

•Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.

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

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, be sure to clean both front wheels.

1.Remove hubcaps, locknuts & washers.

2.Remove wheels from wheel adjusters.

3.Remove any trash or grass cuttings from inside the dust cover, pinion and/ or drive wheel gear teeth.

4.Put wheels back in place.

NOTE: If after cleaning, the drive wheels do not turn freely, contact a Husqvarna or other qualifi ed service center.

BLADE CARE

For best results, blade must be kept sharp. Replace a bent or damaged blade.

CAUTION: Use only a replacement blade approved by the manufacturer of your mower. Using a blade not approved by the manu- facturer of your mower is hazardous, could damage your mower and void your warranty.

TO REMOVE BLADE

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

2.Turn lawn mower on its side. Make sure air fi lter 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 turning counter- clockwise.

5.Remove blade & attaching hardware (bolt, lock washer & hardened washer).

TO REPLACE BLADE

1.Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter.

2.Be sure the trailing edge of blade (oppo- site sharp edge) is up toward the engine.

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