Making Adjustments, Using the Mulcher, Carburetor

•Blade speed should be adjusted to the condition of the lawn.

•For a healthy lawn, never cut more than one- third of the total length of the grass at any one cutting. Lawn should be cut in the fall as long as there is growth.

•This mower is designed to be operated at full throttle to give you the best cut and do the most effective job of bagging the cut grass.

WARNING: If you strike a foreign object, stop the engine. Remove wire from spark plug and ground it. Thoroughly inspect the mower for any damage, and repair the damage before restarting and operating the mower again.

Using the Mulcher

•For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck, preventing proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow in excess of 4", mulching is not recommended. Mow using the grass bag (if so equipped) to reduce the grass height to 3-1/4" maximum before mulching.

Carburetor

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler.

Minor carburetor adjustments may be required to compensate for differences in fuel, temperature, altitude and load. To adjust carburetor, refer to the separate engine manual packed with your mower.

NOTE: A dirty air cleaner will cause an engine to run rough. Be certain air cleaner is clean and attached to the carburetor before adjusting carburetor.

Throttle Control

•If your lawn mower engine is equipped with a throttle control that needs adjustment or if it has been replaced, proceed as follows. Note that engines with fixed throttle cannot be adjusted.

•Remove the screw that secures the cable clamp. Remove the cable clamp from the cable.

NOTE: If you have a Tecumseh engine, simply loosen the screw shown in Figure 10 so the cable will move freely beneath the clamp. It is not necessary to remove the screw and clamp completely.

•Push the throttle control lever on the handle all the way forward as far as it will go, then back it off one
