MAINTENANCE

1.Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and wipe clean. Reinsert the dipstick all the way. Remove the dipstick and check oil level. If oil level is low remove oil fill cap and add oil. Use engine manufacturers specs for type of oil.

2.Pump drive belt compartment: Stop engine and remove key. Tilt seat forward and lift rubber flap. Clean all debris from inside. Inspect rubber flap for proper fit and replace if needed. NOTE: Cleaning may need to be done more frequently in dry conditions.

3.Mower blades: Stop engine and remove key. Lift deck into the transport position and in- spect blades. Sharpen or replace as needed. Check daily or more often if needed. The machine requires more power with dull blades and gives a poor cut. If blades get bent, replace them. Blades shouldn’t have any notches from hitting objects. The air foil on top of the blade should be sufficient to raise the grass for cutting. If blades are in good condition, sharpen at an angle of 22 to 28 degrees about 2-1/2 inches in from the tips. Note: After sharpening, check blades for proper balance, if needed correct balance to prevent excessive vibration.

4.Safety interlock system: Check daily and never operate the mower if this system is not functioning properly. The starter should crank only when the operator is in the seat, the park brake set, blades off and the motion control levers in the neutral slots. If the mower starts with any of these controls on or in an operating position, turn the mower off and repair the system immediately.

6.Air cleaner: Stop engine and remove key. Remove plastic cover and loosen wingnut on the air cleaner. Remove the foam pre-cleaner and wash or replace if needed.

Prolonged effects could damage the engine.

7.Engine oil: Change oil to manufacturers specifications. Stop engine and remove key. Drain oil when engine is warm. Thoroughly clean around cap before removing. Remove oil drain cap from the end of drain hose located at the right rear of unit allow to drain and replace drain cap. Remove oil filter and replace.
