IMPORTANT: Any dust left on the inside of the outlet tube will go into the engine and cause wear.
8.Check the outside surface of the outlet tube for smoothness and cleanness (this is the sealing surface).
9.Insert and seat the safety filter and primary filter element carefully into the canister, applying pressure at the outer rim of the filter; not at the flexible center. Make sure the filter element is completely in place before installing the cover.
NOTE: DO NOT use petroleum based lubri cants on the sealing surfaces of the filter; use talcum powder or dry silicone lubricants if re- quired for filter installation.

Engine Cooling System
Cooling Air Intake System
To prevent engine overheating and possible engine damage, clean grass clippings, chaff, and dirt from the rotating engine air intake screen after every 8 hours of operation. In certain mowing conditions (dry grass, leaves, tree “cotton”, etc.), it may be nec essary to check and clean this area several times each day to prevent engine overheating. Also, visu- ally check inside cylinder head shroud and between cylinder head fins for material packed in this area which would prevent cooling airflow; remove shroud and clean as required.
caution
Operating the engine with a blocked air intake screen, dirty or plugged cooling fins, and/or cooling shrouds removed will cause engine damage from overheating.
