Non-standard acces- sories, cutting attachment, or replacement parts may not operate properly with your unit and may cause damage and lead to personal injury.

Daily Maintenance

Prior to each work day, perform the following:

■■Remove all dirt and debris from the engine, check the cooling fins and air cleaner for clogging, and clean as necessary.

■■Make sure nuts, bolts, and screws (except carburetor idle speed adjusting screws) are tight.

■■Carefully remove any accumulations of dirt or debris from the muffler and fuel tank. Check cooling air intake area at base of crankcase. Remove all debris. Dirt build-up in these areas can lead to engine overheating, fire, or premature wear.

■■Clean any debris or dirt from the cutting attachment.

■■Check for loose or missing screws or components. Make sure the cutter attachment is securely fastened.

■■Check the entire unit for leaking fuel or grease.

300 Hour Maintenance Gearcase Lubrication

The gearcase should be filled with 60

cc(2.0 fl.oz.) of Mobil SHC634 Syn- thetic Gear Oil. A maximum of 75-80 cc can be used, but never to exceed 80 cc. Operation with excessive oil level will result in high operating tempera- tures. Do not overfill!
