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
(See Fig. AB).
h. 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

Sharpening the blade
12.4
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 bladecan
break,causingblade pieces tobe thrown
from the mower.
If the blades are found to be bent, take the
lawn mower to an authorized HENX service
center for inspection.
Sharping frequency
12.5
Sharpening the blade twice during a
mowing season is usually sufficient under
normal circumstances. Sand causes the
blade to dull quickly; if your lawn has sandy
soil,more frequent sharpening may be
required.
When sharpening the blade
26
• Make sure that the blade remains
balanced.
• Sharpen the blade at the original cutting
angle.
• Sharpen the cutting edges on both ends
of the blade, removing an equal amount
of material from each end.
Sharpen the blade in a vise
12.6
a. Remove the blade from the mower
(please see "Removing the blade")
b. Secure the blade in a vise (See Fig. AC)
c. Wear proper eye protection and gloves
and be careful not to cut yourself.
d. Carefully file the cutting edges of the
blade with a fine tooth file or
sharpening stone, maintaining the
original cutting edge angle.
e. To check the blade balance: clamp a
nail or a screw driver with around shank
in the horizontal position.
f. Position the blade so that the nail or
round shank of the screwdriver
supports the blade through its center
hole.
g. Balance the blade horizontally. If either
end of the blade rotates downward,
remove some metal from the heavy or
lower end until the blade is balanced. It
is balanced when neither end drops
(See Fig. AD).
h. Replace the blade on the mower and
tighten it securely (please see "Installing
the blade").
WARNING: An unbalanced blade will cause
excessive vibration when rotating at high
speeds. It may cause damage to the mower
and could break, causing personal injury.
Lubrication
12.7
Lubricate with light oil as directed below at
least once each season after the battery
pack is removed.
• Periodically lubricate the spring and pivot
pin in the quick-adjust lever, the torsion
spring and pivot of the rear-discharge
door with light oil to prevent rust
(See Fig. AE & AF).
• Place the mower into the locked storage
position:
