ENGINE AIR FILTER _______________________________________________________
Check the service indicator each day. If the red band
become visible in the window, replace the filter elements.
Do not remove the elements to inspect or clean. Removal of
the filter that is not necessary increases the risk of dust and
other particles to enter the engine.
When service is needed, first clean the outside of the filter
housing, then remove the old elements carefully.
Clean the inside of the filter housing. Make sure dust and
other particles do not get into the engine inlet hose.
Inspect the new elements. Do not use a damaged element
and never use an incorrect element.
Assemble the secondary and primary filter elements. Make sure the elements seat correctly. Press the button to set the
service indicator.
Assemble the cap to the filter housing. Make sure the cap seals around the filter housing. The dust valve on the cap
must be at the bottom of the filter. Fasten the cap with the two clips.
Check the air filter hoses for wear or damage. Make sure the hose clamps are tight and hold the hoses in position.

FUEL ____________________________________________________________________
Fuel is flammable. Use caution when you add the fuel to the mower. Only use an approved container. The spout
on the container must fit inside the fuel filler neck. Never use containers that are not approved to keep or transfer fuel.
Do not use a nozzle lock open device.
If fuel spills on your clothing, change your clothing immediately
Fill the fuel tank to less than 1 inch (2.5 cm) below the filler neck. Use clean No. 2 ultra low sulfur Diesel fuel with a
minimum Cetane Rating of 45. Use of Diesel fuel additives are not recommended. If fuel additives are used, the fuel
additives must be approved for use in DPF systems. Refer to the engine manual for additional information.
Check fuel hoses and clamps every 50 hours. Replace fuel hoses and clamps at first indication of wear or damage.
Keep fuel according to your local, state or federal regulations and instructions from your fuel supplier.
Never allow the tank to become empty. The level of fuel is shown on the combination gauge.
WARNING
Refuel the mower before you start the engine. When the engine is in operation or while the engine is hot, never
remove the fuel cap or add fuel to the mower.
Refuel outdoors only and do not smoke when you add fuel.
If the fuel spills, do not try to start the engine, but move the mower away from the area. Until fuel vapors are
removed, do not allow the sparks, open flame or other types of ignition.
Never keep fuel containers near an open flame or any device that can cause the ignition of fuel or fuel vapors.
