Mowing tips

Warning! Always inspect area where mower is to be used
and remove all stones, sticks, wire, bones, and other debris
which might be thrown by the rotating blade.
Warning! Mow across the face of slopes, never up-and-down.
Exercise extreme caution when changing direction on slopes.
Do not mow excessively steep slopes. Always maintain good
footing.
Release bail handle to turn mower "Off" when crossing
u
any gravel area (stones can be thrown by the blade).
Set mower at highest cutting height when mowing in rough
u
ground or in tall weeds. Removing too much grass at one
time can cause the motor to be overloaded and to stop.
Refer to troubleshooting guide.
If a grass collection bag (8) is used during the fast growing
u
season, the grass may tend to clog up at the discharge
opening. Release bail handle to turn mower off and
remove the safety key. Remove the catcher and shake
the grass down to the back end of the bag. Also clean
out any grass or debris which may be packed around the
discharge opening. Replace the grass catcher.
If mower should start to vibrate abnormally, release bail
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.
Tips for optimum performance
Slow down in areas where the grass is especially long or
u
thick.
Avoid mowing when the grass is wet from rain or dew-
u
soaked.
Cut your lawn frequently, especially during high growth
u
periods.
Note: It is recommended that your mower be recharged
after use to prolong the battery life.
Frequent charging will not harm your battery, and will ensure
that the battery is fully charged and ready for its next use.
Storing battery not fully charged will shorten battery life.
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.

(Original instructions)
Cut a piece of 2x4 wood (34) (about 610 mm) to keep
u
blade from turning while removing bolt (35).
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 13mm wrench
(36) as shown in figure W.
Note the orientation of each part as you remove it.
u
Remove bolt (35) and washer (37). Pull off blade (38) as
shown in Figure X. The fan (39) should not be removed.
Examine all pieces for damage and replace if necessary.
The blade can only be attached to the fan in one direction.
u
To reassemble, 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.
To tighten, position the piece of wood as shown in Figure
u
Y to keep the blade from turning. Slide the bolt through
the washer and tighten the bolt clockwise into place with a
13mm wrench (36) as shown in Figure Y.

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.
To sharpen blade in a vice (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 (38) in a vice (40).
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 (41) 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.
u
Blade balancing
Check balance of the blade (38) by placing centre hole in
the blade over a nail or round shank screwdriver, clamped
horizontally in a vice. 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.
