Meets CPSC Safety Requirements
DeWALT mowers conform to the safety standards of
the American National Standards Institute, and the U.S.
Consumer Product Safety Commission. The blades turn when
the blade motor isrunning.
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 packs 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.
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 use ANSI Z87.1 (CAN/CSA Z94.3)
approved eye protection and NIOSH/OSHA/MSHA
approved respiratory protection when performingthis.

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 packs 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.
Blade Balancing (Fig. FF)
Check balance of each blade
53
or
52
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.
Blade Sharpening
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 packs 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.
