Also clean out any grass or debris which may be packed

u
handle to turn mower off and remove safety key. Check
immediately for cause. Vibration is a warning of trouble.
Do not operate mower until a service check has been
made.
Refer to troubleshooting guide in manual.
Always release bail handle to turn mower off when leaving
u
it unattended even for a short period of time.
Removing and installing blade
Warning! When reassembling the blade system, ensure each
part is reinstalled correctly, as described below.
Improper assembly of the blade or other parts of the blade
system may cause serious injury.
Warning! Release bail handle to turn mower off, wait for the
blade to stop, and unplug mower.
Cut a piece of 2x4 wood (27) (about 610 mm) to keep
u
blade from turning while removing bolt (28).
Wear gloves and proper eye protection.
u
Turn the mower on its side. Be careful of sharp edges of
u
blade. Position wood and unscrew bolt with 9/16" wrench
(29) as shown in figure S.
Note the orientation of each part as you remove it.
u
Remove nut (30). Pull off washer (31), the blade insulator
(32), and the blade (33) as shown in Figure T. Examine all
pieces for damage and replace if necessary.
Note: The fan should not be able to be removed.
To reassemble, slide the blade (33) on. It can only be at-
u
tached to the fan in one direction and location. Line up the
D-shaped hole of the blade with the D-shaped post of the
fan, ensuring the writing on the blade faces out away from
the mower. Place the insulator (32) on the blade so that
the two outer ribs extend past the blade. Place the square
washer (31) on top of the insulator so that it sits inside of
the two outer ribs on the insulator. Replace the nut (30)
with the wide side against the washer.
To tighten firmly, position the piece of wood as shown
u
in figure U to keep the blade from turning. Slide the bolt
through the washer and screw bolt into place. Tighten with
the wrench.
Blade sharpening
Keep blade sharp for best mower performance. A dull blade
does not cut grass cleanly. Use proper eye protection while
removing, sharpening, and installing blade. Ensure that safety
key and battery pack is removed.
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.
Note: Replace bent or damaged blade immediately.
When sharpening the blade:
Make sure blade remains balanced.
u
Sharpen blade at the original cutting angle.
u
Sharpen cutting edges on both ends of blade, removing
u
equal amounts of material from both ends.

(Original instructions)
To sharpen blade in a vise (fig. V)
Be sure the bail handle is released, the blade has stopped
u
and the mower is unplugged before removing the blade.
Remove blade from mower. See instructions for removing
u
and installing blade.
Secure blade (33) in a vise (36).
u
Wear proper eye protection and gloves and be careful not
u
to cut yourself.
Carefully file the cutting edges of the blade with a fine
tooth file (39) or sharpening stone, maintaining the angle
of the original cutting edge. Check balance of blade. See
instructions for blade balancing. Replace blade on mower
and tighten securely.
Blade balancing
Check balance of the blade (35) by placing centre hole in
the blade over a nail or round shank screwdriver, clamped
horizontally in a vise. if either end of the blade rotates down-
ward, file along the sharp edge of that dropping end. Blade is
properly balanced when neither end drops.
Lubrication
No lubrication is necessary. Do not oil the wheels. They have
plastic bearing surfaces which require no lubrication.
Cleaning
Release bail handle (2) to turn mower off, let the blade come
to a stop and then remove safety key. Use only mild soap
and a damp cloth to clean the mower. Clean out any clippings
which may have accumulated on the underside of the deck.
After several uses, check all exposed fasteners for tightness.
Preventing corrosion
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 (2) to turn mower off and unplug mower. Wipe all
exposed parts with a damp cloth.
