Fig. 10 7.6 FOR THE BEST RESULTS WHEN MOWING First clear the lawn of debris: Be sure that the grass is clear of stones, sticks, wire or other objects, which could be accidentally thrown out by the mower in any direction and cause serious injury to the operator and others as well as damage to property and surrounding objects. Avoid cutting wet grass: For effective mowing do not cut wet grass, because it tends to stick to the underside of the deck preventing proper mowing of the grass.
7.8 DECK The underside of the mower deck should be cleaned after each use to prevent a buildup of grass clippings, leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may prevent proper mulching. The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug wire is disconnected). 7.
CAUTION: Do not allow dirt or dust to clog the air filter foam element. The engine air cleaner element must be serviced (cleaned) after 25 hours normal mowing. The foam element must be serviced regularly if the mower is used in dry dusty conditions. To CLEAN AIR FILTER 1.1 Remove the locking knob.(For Briggs engine; Fig.13A) 2. Remove the filter cover. 3. Wash filter element in soap water. DO NOT USE PETROL! 4. Air dry the filter element. 5.
