spacer
45
onto the blade shaft
49
as shown in Fig. CC.
NOTE: Align the keys

on the bladeshaft
49
as shown in Fig.CC.
14. Install the blade assembly bolt

Blade Balancing (Fig. EE, FF)
Check balance of each blade
52
or
53
by placing the keyed
mounting hole
55
over a nail or round screwdriver
59
,
clamped horizontally in a vise
34
. If either end of a blade
rotates downward, file along the sharp edge of that dropping
end. Blade is properly balanced when neither enddrops.
Cleaning (Fig. A)

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear approved eye protection and
approved dust mask when performing this procedure.

WARNING: Never use solvents or other harsh chemicals
for cleaning the non-metallic parts of the tool. These
chemicals may weaken the plastic materials used in
these parts. Use a cloth dampened only with water and
mild soap. Never let any liquid get inside the tool; never
immerse any part of the tool into aliquid.
• Release bail handle
8
to turn mower off, let the blades
come to a stop.
• Remove the battery pack and safety key.
• Clean out any clippings which may have accumulated on
the underside of the deck. Do not spray with water or any
other liquids.
• After several uses, check all exposed fasteners fortightness.
Corrosion (Fig. A)
Fertilizers and other garden chemicals contain agents which
greatly accelerate the corrosion of metals. If you mow in areas
where fertilizers or chemicals have been used, the mower
should be cleaned immediately afterward as follows:
Release bail handle
8
to turn mower off and remove battery
and safety key. Wipe all exposed parts with a dampcloth.

CAUTION: Do not pour or spray water on the mower
in an attempt to clean it. Do not store the tool on or
adjacent to fertilizers or chemicals. Such storage can cause
rapidcorrosion.
Blade Sharpening (Fig. EE)
KEEP BLADE SHARP FOR BEST MOWER PERFORMANCE. A DULL
BLADE DOES NOT CUT GRASSCLEANLY.

WARNING: Use gloves and proper eye protection while
removing, sharpening, and installing blades. Ensure that
safety key and battery pack areremoved.
Sharpening the blades 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. REPLACE BENT OR DAMAGED
BLADESIMMEDIATELY.
When Sharpening a Blade:
• Make sure blade remainsbalanced.
• Sharpen blades at the original cuttingangle.
• Sharpen cutting edges on both ends of blade, removing
equal amounts of material from bothends.
To Sharpen Blade in a Vise (Fig. EE)
1. Be sure the bail handle is released, the blades have stopped
and safety key and battery pack are removed before
removing theblades.
2. Remove blades from mower. See instructions for Removing
and InstallingBlades.
3. Secure blade
52
or
53
in a vise
34
.
4. Wear proper eye protection and gloves and be careful not
to cutyourself.
5. Carefully file the cutting edges of the blade with a fine tooth
file
54
(not included) or sharpening stone (not included),
maintaining the angle of the original cuttingedge.
6. Check balance of blade. See instructions for BladeBalancing.
7. Replace blades on mower and tightensecurely.
