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.
u
Release bail handle to turn mower “Off” when crossing
any gravel area (stones can be thrown by the blade).
u
Set mower at highest cutting height when mowing in rough
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.
u
If a grass collection bag (8) is used during the fast growing
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.
u
If mower should start to vibrate abnormally, release bail
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.
u
Always release bail handle to turn mower off and remove
safety key when leaving it unattended even for a short
period of time.
Tips for optimum use:
u
Slow down in areas where the grass is especially long or
thick.
u
Avoid mowing when the grass is wet from rain or dew-
soaked.
u
Cut your lawn frequently, especially during high growth
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 remove safety key and battery pack.
u
Cut a piece of 2x4 wood (31) (about 2 feet long) (610 mm)
to keep blade from turning while removing bolt (32).
u
Wear gloves and proper eye protection.
u
Turn the mower on its side. Be careful of sharp edges of
blade. Position wood and unscrew bolt with 1/2” wrench
(33) as shown in figure W.
u
Remove bolt and washer (34). pull off blade (35) as shown
in figure X. The fan (36) should not be removed. Examine
all pieces for damage and replace if necessary.
u
The blade can only be attached to the fan in one direction.
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.
u
To tighten firmly, position the piece of wood as shown
in figure Y 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:
u
Make sure blade remains balanced.
u
Sharpen blade at the original cutting angle.
u
Sharpen cutting edges on both ends of blade, removing
equal amounts of material from both ends.
To sharpen blade in a vise (fig. Z)
u
Be sure the bail handle is released, the blade has stopped
and safety key and battery pack removed before removing
the blade.
u
Remove blade from mower. See instructions for removing
and installing blade.
u
Secure blade (35) in a vise (38).
u
Wear proper eye protection and gloves and be careful not
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 (fig. Z1)
Check balance of the blade (35) by placing centre hole in the
blade over a nail or round shank screwdriver (40), clamped
horizontally in a vise (38). if either end of the blade rotates
downward, 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
