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 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 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. EE, FF)
Check balance of each blade
53
or
52
by placing the keyed
mounting hole
55
over a nail or round screwdriver
33
,
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.
• 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 packs are removed before
removing theblades.
2. Remove blades from mower. See instructions for Removing
and InstallingBlades.
3. Secure blade
53
or
52
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.
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.
8. Install sharpened or new blades onto the blade hub
48
as
shown in Fig.AA, BB.
9. Blade 2
52
is installed first, the bolt holes being aligned
with the outer blade studs
56
and keyed mounting
hole
55
on the blade hub
48
as shown in Fig. AA.
NOTE: Ensure the keyed mounting hole
55
engages the
key
57
on the blade hub
48
as shown in Fig.AA. The
key
57
should be proud of blade 2
52
.
10. Blade 1
53
is installed second, the bolt holes being aligned
with the inner blade studs
58
and keyed mounting
hole
55
on the blade hub
48
as shown inFig.BB.
NOTE: Ensure the keyed mounting hole
55
engages
the key
57
on the blade hub
48
and sits flush as
showninFig.BB.
NOTE: If blade 1
53
is not flush with the key
57
on the
blade hub
48
, then the blades have been mounted in the
incorrect order and must be reversed.
11. Thread the four blade nuts
51
onto the bladestuds
56
and
58
as shown in Fig. AA, BB. Hand tighten the four
blade nuts
51
.
NOTE: When replacing sharpened or new blades on blade
hub
48
make sure the bottom of the blade as marked
Grass Side will be facing the ground when the mower is
returned to its normal uprightposition.
12. Secure the blade assembly
47
in a vise
34
. Tighten the four
blade nuts
51
clockwise with a 14 mm (9/16") wrench
44
(not included). Torque the four blade nuts
51
to 18-27 Nm
(13-20ft-lbs).
13. In this order, install the blade assembly
47
and keyed
spacer
45
onto the blade shaft
49
as shown in Fig. CC.
NOTE: Align the keys
46
on the keyed spacer
45
with the
key slots
60
on the bladeshaft
49
as shown in Fig.CC.
14. Install the blade assembly bolt
43
and hand tighten.
15. Position the 38 mm x 89 mm timber
42
between the blade
assembly
47
and outer lip of deck as shown in Fig. DD to
keep the blades from turning.
16. Fully tighten the blade assembly bolt
43
using a
14 mm (9/16")wrench
44
(not included). Torque the blade
assembly bolt
43
to 50-68 Nm (37-50 ft-lbs).
17. Return the mower to its normal uprightposition.
