Cutting Unit Maintenance

Blade Safety

Refer to and complete the procedure in
Safety (page 33). A worn or damaged blade or
bedknife can break, and a piece could be thrown
toward you or bystanders, resulting in serious
personal injury or death.
•
Inspect the blades and bedknives periodically for
excessive wear or damage.
•
Use care when checking the blades. Wear gloves
and use caution when servicing them. Only
replace or backlap the blades and bedknives;
never straighten or weld them.
•
On machines with multiple cutting units, take care
when rotating a reel; it can cause the reels in the
other cutting units to rotate.
Installing and Removing
the Cutting Units
Note:
When sharpening, setting the height-of-cut,
or performing other maintenance procedures on the
cutting units, store the cutting unit reel motors in the
storage location on the front of the suspension arms
to prevent damage to them.
Important:
Do not raise the suspension to the
transport position when the reel motors are in
the holders in the machine frame. Damage to the
motors or hoses could result.
Important:
Whenever you need to tip the cutting
unit, prop up rear of cutting unit to ensure that
the nuts on the bedbar adjusting screws are not
resting on work surface
