Check Engine Crankcase OIL Level

Assembly Instructions

DANGER

Handle gasoline with care. Gasoline is high- ly flammable and its vapors are explosive. Use safe refueling procedures:

•DO NOT fill fuel tank with the engine run- ning.

•If the engine is hot, allow to cool before refueling.

•Use an approved fuel container.

•Fuel the mower outdoors.

•DO NOT smoke while refueling.

•Avoid spilling fuel; use a funnel or spout.

•DO NOT overfill the fuel tank; fill up to about 1 in. (25 mm) below the top of tank.

IMPORTANT: DO NOT permit dirt or other foreign matter to enter the fuel tank. Wipe dirt from around the filler cap before removing. Use a clean fuel stor- age container and funnel.

IMPORTANT: DO NOT mix oil with gasoline. Always use fresh, automotive grade unleaded gas- oline. DO NOT use premium, white, or high-test gasoline. DO NOT use additives, such as carburetor cleaners, deicers, or moisture removing agents. DO NOT use gasoline blended with methyl alcohol.

Check the engine crankcase oil level before use and after each 8 hours of continuous operation. Refer to LUBRICATION for Checking Engine Crankcase Oil Level in Maintenance Instructions.

CHECK AND SERVICE ENGINE AIR CLEAN- ER SYSTEM

•Check condition, cleanliness, and security of the complete air filter element (clean air filter every 100 hours). For detailed procedures, refer to CLEANING the Air Cleaner System in Mainte- nance Instructions.

CHECK ENGINE COOLING SYSTEM

Check that the engine cooling air intake screen is free of obstruction by grass clippings or debris and clean if required. Also, cylinder head cooling fins should be inspected and cleaned if any build-up of debris is noted. Contact your Walker Dealer to perform this procedure.

CHECK SECURITY OF DRIVE TIRE MOUNT- ING NUTS

The eight (8) Drive Tire mounting nuts should each be torqued to 75-85 ft-lbs. (101.7-115.2 N⋅m).

INSPECT TWO (2) DRIVE BELTS

Engine/PTO and Ground Drive.

CHECK HYDROSTATIC TRANSAXLE OIL LEVEL

Refer to LUBRICATION for Transaxle Lubrication in Maintenance Instructions.

CHECK TIRE PRESSURE

Deck Caster Wheel = 20 PSI (137 kPa)

Drive	=	15 PSI (103 kPa)
Rear	=	20 PSI (137 kPa)

CHECK AND CLEAN GRASS BUILDUP UNDERNEATH MOWER DECK

Refer to CLEANING in Maintenance Instructions for deck cleaning information.

DANGER

Never operate cutter blades with deck in raised position because it is hazardous.

The tilt-up deck can be secured in the raised position by unlocking the deck lock levers on each side of the carrier frame and inserting the deck hook into the tilt- up latch on the tractor body. Before operating the tractor, make sure to re-engage the deck lock levers after lowering the deck to the normal operating posi- tion.
