CHECK ENGINE OIL

IMPORTANT: Change engine crankcase oil after first two (2) hours of operation. Thereafter, change oil every twenty five hours of operation (more often in dusty, dirty conditions). Refer to Engine Manual for oil type and grade and detailed instructions.

Engine Oil Check and Change

The engine crankcase oil should be checked before each use or every five (5) hours of operation. Oil level MUST be maintained in safe operating range on dipstick at all times or engine damage will result.

IMPORTANT: DO NOT overfill. Be sure engine is level when adding oil.

See Engine Manual for detailed instructions.

CHECK MOWER BLADE

See figures 10 and 11.

Check blade for wear.

Check blade mounting: blade must be secure and cap screw torqued to 37.5 - 50 ft. lbs. (lock washer should be fully compressed by cap screw).

When blade needs sharpening:

1.Block blade to prevent rotation.

2.Remove cap screw, lock washer and blade from shaft.

3.Sharpen both ends of blade at original angle (25°), removing equal amounts of material from each end to maintain proper blade balance. New blades are balanced to within 1.3 in. oz. at factory. DO NOT grind around corner at tip of blade. If cutting edge of blade cannot be sharpened in a straight line to within 1/8 of an inch of its end, replace blade with Husqvarna replacement blade only.

4.Install blade, lock washer and cap screw. Blade must be secure and cap screw torqued to 37.5 - 50 ft. lbs. (lock washer should be fully compressed by cap screw).

IMPORTANT: If mower is used under sandy soil conditions, replace blades when air lifts become eroded.
