equipment such as a dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
c. Prevent unintentional starting.
Ensure the switch is in the off-
position before connecting to power
source and/or battery pack, picking
up or carrying the tool. Carrying
power tools with your nger on the
switch or energising power tools that
have the switch on invites accidents.
d. Remove any adjusting key or
wrench before turning the power
tool on. A wrench or a key left
attached to a rotating part of the power
tool may result in personal injury.
e. Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
f. Dress properly. Do not wear loose
clothing or jewellery. Keep your
hair, clothing away from moving

Power tools are dangerous in the
hands of untrained users.
e. Maintain power tools and
accessories. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool's operation. If damaged,
have the power tool repaired before
use. Many accidents are caused by
poorly maintained power tools.
f. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to
bind and are easier to control.
g. Use the power tool, accessories and
tool bits etc. in accordance with
these instructions, taking into
account the working conditions and
the work to be performed.
Use of the power tool for operations
different from those intended could
result in a hazardous situation.
h. Keep handles and grasping

Important charging notes
uLongest life and best performance can be obtained if the
battery pack is charged when the air temperature is
between 60°F and 80°F (16°- 27°C).
uDO NOT charge the battery pack in an air temperature
below +40°F (+4.5°C), or above +105°F (+40.5°C).
This is important and will prevent serious damage to the
battery pack.
uThe charger and battery pack may become warm to touch
while charging. This is a normal condition, and does not
indicate a problem.
To facilitate the cooling of the battery pack after use, avoid
placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
uIf the battery pack does not charge properly:
uCheck current at receptacle by plugging in a lamp or
other appliance

uIf mower should start to vibrate abnormally, release bail
handle to turn mower off, remove the safety key and
battery packs. Check immediately for cause. Vibration is a
warning of trouble. Do not operate mower until a service
check has been made.
uFor best cutting results, keep blade sharpened and
balanced.
uInspect and thoroughly clean mower after each use as a
deck with caked grass will degrade performance.
uAlways release bail handle to turn mower off, remove
safety key and battery packs when leaving it unattended
even for a short period of time.
The following suggestions will help you to obtain
optimum runtime from your cordless mower:
uSlow down in areas where the grass is especially long or
thick.
uAvoid mowing when the grass is wet from rain or
dew-soaked.
uCut your lawn frequently, especially during high growth
periods.
Note: It is recommended that your battery packs be recharged
after use to prolong the battery pack life. Frequent charging
will not harm your battery pack, and will ensure that the

Warning! Use gloves and proper eye protection while
removing, sharpening, and installing blade. Ensure that safety
key and battery pack are 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. Replace bent or damaged blade
immediately.
When sharpening the blade:
uMake sure blade remains balanced.
