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,but do not screw down. Remove the dipstick and
check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil.
2.
Pump drive belt compartment: Stop engine and remove key. Tilt seat forward and clean all
debris from inside. NOTE: Cleaning may need to be done more frequently in dry conditions.
3.
Mower blades: Stop engine and remove key. Inspect blades and 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.
