TO SHARPEN BLADE

NOTE: We do not recommend

sharpening blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will

cause eventual damage to lawn 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.

LUBRICATION

Use only high quality detergent oil rated with API service classification SF, SH or

SG. Select the oil'sSAE viscosity grade according to your expected operating temperature.

SAE VISCOSITY GRADES

"30' -2O" -10" O' 10" 20" 30"

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi--viscosity oils (5W30, 10W30 etc.) improve starting in

cold weather, these multi--viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of

operation or at least once a year if the lawn mower is not used for 25 hours in

one year.

Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil revel
