3. While wearing protective gloves, position the blade on the
inner flange with the surface stating “THIS SIDE FACING
GRASS” facing toward the outside (Fig. 21).
4. Determine the direction of blade according to
the position of mounting holes.
5. Mount the bolt into the shaft and turn it clockwise by hand
to pre-tighten it.
6. While still wearing protective gloves, hold the blade with
one hand and turn the fan with the other hand to align the
holes in the blade with the through holes in the inner flange
(Fig. 22).
7. Place a metal rod (e.g., a 3.5” length screw bit) with
diameter less than 1/4 inch (6.35mm) into the aligned
holes to act as a stabilizer. Place another metal rod (e.g., a
3.5” length screw bit) with diameter less than 5/16” (8mm)
into the fixing hole to act as another stabilizer (Fig. 23).
8. Use a 9/16 inch (14mm) torque wrench (not included) to
tighten the bolt clockwise. The recommended torque for the
blade bolt is 36-43 ft-lb (49-59Nm).
SHARPENING THE BLADE
WARNING: Always protect your hands by wearing heavy
gloves or wrapping the cutting edges with rags or other
materials when performing any maintenance on the mower
blade. Always remove the battery pack when servicing or
transporting the mower.
WARNING: Use proper eye protection while
removing, sharpening, and installing the blade.
WARNING: A worn, cracked, or damaged blade can break
and pieces of the damaged blade can become dangerous
projectiles. Thrown objects can cause serious injury. Inspect the
blade regularly and do not operate the mower with a worn or
damaged blade.
NOTICE: Keep the blade sharp for best mower performance. A
dull blade does not cut grass cleanly or mulch properly.
A dull blade can be sharpened, but a blade that is excessively
worn, bent, cracked, or otherwise damaged must be replaced. A
worn or damaged blade can break, causing blade pieces to be
thrown from the mower.
If the blades are found to be bent, take the lawn mower to
an authorized HENX service center for inspection.
