5 MAINTENANCE AND LUBRICATION
5.19 INSPECTING BLADES__________________________________________________
As indicated in the Maintenance chart or the cutting unit is removed from the mower. Inspect the condition of the
blades. Replace any blade that has bends, grooves or cracks.
A bent blade can have a small crack that can increase and cause a piece of the blade to break. The bent blades
can cause vibration and other stress on the mower.
The dust or sand particles can wear a dangerous groove in the blade between the air vanes and the flat part of
the blade. The groove can quickly increase in size and allow a piece of the blade to break.
5.20 HOW TO SHARPEN THE BLADES ________________________________________
Put a chock between the blade and The cutting unit housing to prevent blade rotation.
When you prepare or sharpen the blade, do not follow the original pattern of the blade. Grind new cutting edges
at an angle. If the maximum (A) of 1/2 inch 13-mm blade loss has occurred, do not sharpen, replace the blade.
To stop any blade balance problems, grind an equal amount of material from both ends of the blades. A blade
that is not balanced will cause vibration and can damage the mower. Use a blade balancer (4254850, obtainable
from your local Ransomes, Jacobsen dealer, distributor) to check the blade after you sharpen.
Torque center blade bolt to 75 to 90 ft.Lb. (100 to 120 Nm).
CAUTION
Be careful when you check the blades to prevent injury to the hands and fingers.
WARNING
Never try to correct or repair a damaged blade. Always replaced a damaged blade.
The bends, grooves or cracks can cause a piece of the blade to become loose and be discharged from the
mower. The broken blade pieces can cause injury to persons or property damage.
WARNING
The cutting unit blades can have sharp edges. To prevent
injury, use caution when you service or hold the blade.
When you remove more than 1/2 inch 13 mm from the blade,
the tip can break and be discharged from the mower. The
broken blade pieces can cause injury to persons or property
damage.
