MAINTENANCE

.:’

,~,

Regular maintenance of your Simplicity tractor will great- ly increase its useful life and reduce repair costs. A wide variety of attachments and accessories permit use of your tractor throughout the year. BECAUSE YOUR TRACTOR IS A MULTI-SEASON TOOL, IT IS VERY IMPORTANT TO SERVICE THE ENGINE FOR THE SEASON IN WHICH IT WILL BE OPERATED. Be sure to change to winter grade oil before making cold temperature starts. Fuel refiners change the volatility of gasoline for each sea- son of the year. Using the proper fuel for the season of op eration will improve starting. Refer to your Briggs and Stratton manual for engine maintenance in addition to the steps listed here.

2.Change Engine Oil: Drain the crankcase when the en- gine is warm. Remove the oil drain plug found on the left. See figure 29. After the oil has completely drained replace the plug and tighten securely. Refill the crankcase with four pints of a high quality detergent oil classified MS. It is essential to long engine life that the crankcase oil remain free of contaminants. Use a clean funnel and clean the top of the oil can before opening to insure foreign ma- terial does not get in the crankcase when you are adding cd.

EVERY 25 HOURS

Every 25 hours or oftener under extremely dusty condi- tions, all attachments should be removed from the trac- tor and the following maintenance procedures performed:

1.Clean the Cooling System: Continued operation with a clogged cooling system causes severe overheating and possible engine damage. Remove all grass and chaff from the engine shrouds and fins, and the flywheel screen at the lower rear of the tractor.

3.Service the Air Cleaner: Turn the capscrew at the top center of the air cleaner counterclockwise and remove. Re- move the cover and foam element. Remove the screen from inside the foam element. Wash the element in kero- sene or liquid detergent and water to remove dirt. Wrap foam in cloth and squeeze dry. Saturate the foam in en- gine oil and squeeze to remove excess. Put the screen in- side the foam element, being sure the sealing lip is over the end of the screen at both the top and bottom. Replace the element, cover and capscrew and tighten securely.
