Failure to perform these steps properly can damage the lawn mower or shorten its lifespan. UNPACKING Unpack the lawn mower and all its parts, and compare against the list below.

ADJUSTING THE CUTTING HEIGHT Warning! Cutting height adjustments should only be performed after the engine and blades have come to a complete stop! It is always best to begin cutting your lawn with a higher deck height to prevent scalping your lawn. Rear wheel The cutting height for the rear wheels is adjusted with a single lever. Actuate the adjustment lever and pull it to the required position. Please make sure that the lever locks into position.
ENGINE START/STOP LEVER Engine start/stop lever This lawn mower comes equipped with an engine start/stop lever to prevent unintentional starting and to ensure safe operation. Releasing this lever will quickly stop the blade in case of danger. The lever must be actuated before the lawn mower is started. When the engine start/stop lever is released, it must return to its initial position.
It’s import to keep the underside of the mower deck clean and remove grass build-up. This buildup will decrease mulching quality, and make it harder for the equipment to bag the grass. Always mow along inclines (not up and down). You can prevent the lawn mower from slipping down by holding a position at an angle upwards. Select the cutting height according to the length of the grass. If necessary, mow a number of times so that you never cut more than 2 inches of grass in one go.
MAINTENANCE Proper routine maintenance of this mower will help prolong the life of the machine. Always observe safety rules when performing any maintenance. The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full valve from warranty, operator must maintain the lawn mower as instructed here. Changing of engine-governed speed will void engine warranty. All adjustments should be checked at least once each season.
RECCOMENDATIONS FOR OFF SEASON STORAGE CAUTION: Never place any type of storage cover or tarp on the MOWER while it is still hot. If the MOWER is being stored for short periods of time (30 to 60 days), add stabilized fuel to the gas tank until it is full. Run the engine for 2 – 3 minutes allowing stabilized fuel mixture to circulate through the carburetor. NOTE: Keeping the fuel tank full, reduces the amount of air and vapor and helps reduce deterioration of the fuel.

Cause Engine start/stop lever disengaged. Spark plug wire disconnected. Fuel tank empty or stale fuel. Engine not primed. Faulty spark plug. Blocked fuel line. Engine flooded. Spark plug wire loose. Blocked fuel line or stale fuel. Water or dirt in fuel system. Dirty air filter Engine oil lever low. Air flow restricted.
