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 gure W.

u Remove bolt and washer (34). pull off blade (35) as shown

in gure 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 rmly, position the piece of wood as shown

in gure 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

sufcient 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 (g. 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 le the cutting edges of the blade
with a ne tooth le (39) or sharpening stone, maintaining

the angle of the original cutting edge. Check balance of
