Replacing the Blades
Replace the blades if they hit a solid object, are out of
balance, or are bent.
Important:
Replace all the blades at the same
time to maintain consistent wear and weight
balance.
1.
Loosen the 2 bolts securing the blade-access
cover and move the cover out of the way (

Turn the flywheel until you see the blade nut.
Remove the blade nut.
Note:
The square neck on the bolt prevents the
bolt from spinning. The blade will drop after you
remove the nut.
3.
With assistance from another person, install a
new blade, nut, washer, and bolt (
).
Important:
Use new hardware when
installing a new blade.

Sharpening the Blades
Remove the blades as described in
and use a file to sharpen the cutting

edge is 0.8 to 1.6 mm (1/32 to 1/16 inch) thick.

Service Interval:
Before each use or daily
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed
within a few hours by a doctor familiar with
this form of injury; otherwise, gangrene may
result.
•
Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
•
Use cardboard or paper to find hydraulic
leaks; never use your hands.
Removing Debris
Every 50 hours
Regular cleaning and washing increases the lifespan
of the machine. Clean the machine directly after use.
Use care when using a high-pressure sprayer,
because it can damage decals, the planetary, and the
hydraulic system.
