ing to "Sharpening the Cutting Blade". WARNING!
An unbalanced blade can cause vibration that
could damage the mower or cause personal injury.
8. Install a new or sharpened blade. The circle and
triangle holes of the blade must align onto the
circle and triangle posts of the blade motor fan. The
shear plate edges must wrap around the blade.
9. Tighten the blade nut to 313-347 in.lbs, using a
torque wrench.
Sharpening the Cutting Blade
WARNING
Keep cutting edges sharp and
clean for best and safest perfor-
mance. Use a recommended MILWAUKEE re-
placement blade only. Use caution when servic-
ing blade. Wrap the blade or wear gloves. Replace
damaged blade. Do not repair damaged blade or
alter blade mounting holes.
1. Clean the blade.
2. Sharpen a dull blade equally at each end to main-
tain the balance. Use a le to remove minimal
shavings to achieve a sharp blade.
3. Check the blade's balance by supporting it on a
nail through its center hole. Hold the nail horizon-
tally. If either end of the blade rotates downward,
remove some metal from the heavy or lower end.
Repeat until the blade is balanced evenly on the
nail. It is balanced when neither end drops.
Maintaining Mower
Keep your mower, battery packs and charger in good
repair by adopting a regular maintenance program.
Inspect your mower for issues such as undue noise,
misalignment or binding of moving parts, breakage
of parts, or any other condition that may a󰀨ect the
mower operation. Return the mower, battery pack,
and charger to a MILWAUKEE service facility for
repair.
If the mower does not start or operate at full power
with a fully charged battery pack, clean the contacts
on the battery pack. If the mower still does not work
properly, return the mower, charger and battery pack,
to a MILWAUKEE service facility for repairs.
