Before you clean, adjust, or repair this equipment, disengage all
drives, lower implements to the ground, engage parking brake,
stop engine, and remove key from ignition switch to prevent
injuries.
Make sure the mower is parked on a solid and level surface.
Never work on a mower that is supported only by the jack. Always
use jack stands.
1.
Adjustment and maintenance should always be performed by a
qualified technician. If proper adjustments cannot be made,
contact an Authorized Jacobsen Dealer.
2.
Inspect the equipment on a regular basis, establish a
maintenance schedule and keep detailed records.

INSPECTING BLADES _____________________________________________________________________
1.
Every 50 hours of operation or whenever blades are removed
from mower, carefully examine the blades to make sure they are
in good operating condition. Blades showing any bends (G),
grooves (H) or cracks (J) must be replaced.
!
Use care when checking blades to avoid pinching hands and
fingers between blade ends.
WARNING
!
Never attempt to straighten, weld, or repair a damaged blade.
Always replace a damaged blade.
2.
Any of the above conditions can cause a piece of the blade to
break away and be thrown from the mower causing very
serious injury to bystanders or property damage.
3.
A bent blade could have a microscopic crack (G) that can grow
and allow a piece of the blade to break. Bent blades will also
create vibration and other stress on the machinery.
4.
Dust or sand particles can wear a dangerous groove in the
blade (H) between the air vanes and the flat portion of the
blade that will rapidly grow and produce a crack (J) permitting a
piece of the vane to break off.
