WARNING:
Never mow with dull blades! Blades that are bent should be replaced! The cutting blades are sharp and can cause severe injury. Wrap the cutting surface of the blade with a rag to avoid injury. A dull blade requires more horsepower than one that is sharp.
3.Sharpening a Blade.
a.Set the parking brake.
b.Clean any debris from the blades. Keep blades sharp and free of build up at all times.
c.Sharpen blades evenly at the original 30° angle to maintain balanced cutting blades. Do not sharpen the underside of the blades. Use a electric blade sharpener, a conventional electric grinder or a hand file to sharpen the blades.
d.Replace any blade with severe nicks or dents that cannot be removed by filing.
e.Check the balance of the blade after sharpening by placing it on a blade balancer. Do not use un- balanced blades.

d.Remove the drive belts. (See 4. Changing Blade Drive Belts.)
e.Remove the cutter blade. (See 2. Changing a Blade.)
f.Using a wrench or socket rachet remove four hex nuts, and the four hex head cap screws. Remove the spindle assembly.
B.Hydraulic Oil
WARNING:
Never overfill the hydraulic units. Damage can occur if the oil level is not within the proper operating range.
Note: When adding hydraulic oil, do so in small quantities and recheck the oil level before adding more. It is important that you do not overfill the reservoir to allow for fluid expansion.
1.Adding Hydraulic Oil (use Rimula SAE15W40)
a.Place the Mower on a level surface and engage the parking brake.
b.Stop the engine and remove the key from the ignition switch.
c.Clean the area around the Hydraulic Oil fill neck.
d.Remove the hydraulic fill cap and check the level. The correct level is a 1/4” below the oil tank fill neck.
e.Pour hydraulic oil into the reservoir a 1/4” below the oil tank fill neck and 1.5 ounces of Ornite additive, if necessary.
2.Draining Hydraulic Oil
Used hydraulic oil must be disposed of properly. Do not pour it down a drain or sewer, or dump it on open land, this creates an environmental hazard. Please be aware of the environment when disposing of used oil.
a.Place the Mower on a level surface and engage the parking brake.
b.Stop the engine and remove the key from the igni- tion switch.
c.Remove the mower deck. See section on Mower Deck.
