Don’t force the lawn mower – it will do the job better and more safely at the rate for which it was designed.
Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. Also, avoid
discharging material against walls or obstructions, which may cause discharged material to ricochet back toward the operator.
To help avoid blade contact or an injury from thrown objects, stay in the operator zone behind the handles and keep children,

8
bystanders, helpers and pets at least 100 feet (30m) from the mower while it is in operation. Stop the machine if anyone enters
the area.
Always wear safety glasses or safety goggles during operation and while performing an adjustment or repair to protect your
eyes. Thrown objects that ricochet can cause serious injury to the eyes. Always use a face or dust mask if the operation is
dusty.
Dress properly – Do not wear loose clothing or jewelry. They can be caught in moving parts. Use of rubber gloves and footwear
is recommended when working outdoors. Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and
pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals,
slippery or lightweight (e.g., canvas) shoes.
Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet.
A missing or damaged discharge cover can cause blade contact or injuries from thrown objects.
Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold
onto the mower if you are falling; immediately release the handle.
Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction, first
look down and behind you to avoid tripping, and then follow these steps:
Step back from mower to fully extend your arms.

Pull the mower back slowly, no more than half way toward you.
Repeat these steps as needed.
Do not operate the mower while under the influence of alcohol or drugs.
Stay alert – watch what you are doing. Use common sense. Do not operate the lawn mower when you are tired.
The motor/blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device
inoperative and may result in personal injury through contact with the rotating blade. The motor/blade control handle must
operate easily in both directions and automatically return to the disengaged position when released.
Avoid dangerous environments – Don’t use lawn mowers in damp or wet locations so as to avoid slipping and falling during
operation.
Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release
the motor/blade control handle immediately and the blade will stop rotating within three seconds.
Stop the blade when crossing gravel drives, walks or roads.
If the equipment should start to vibrate abnormally, immediately stop the motor, remove the battery and check for the cause.
Vibration is generally a warning of trouble.
Before cleaning the machine, unclogging the chute or removing or replacing the grass bag, mulching insert, or side discharge
chute, turn the motor off and wait until the blade comes to a complete stop, then remove the battery pack. The cutting blade
continues to rotate for a few seconds after the motor is shut off. Never place any part of the body in the blade area until you
are sure the blade has stopped rotating.
Never operate the mower without the proper trailing shield, discharge cover, grass bag, mulching insert, side discharge chute,
motor/blade control handle or other safety protective devices in place and working. Never operate the mower with damaged
safety devices. Failure to do so can result in personal injury.

MOWER OVERLOAD PROTECTION
To prevent overload conditions, do not try to remove too much grass at one time. Slow down your cutting pace or raise the cut
height.
Your mower has built-in overload circuit protection. When the mower is overloaded, the motor will stop and the power indicator on
the mower will flash red. Remove the battery pack from the mower. Check to see if grass has collected beneath the deck and clear
it if necessary, then install the battery and restart the mower.
BATTERY HIGH TEMPERATURE PROTECTION
The battery pack will generate heat during operation. The heat dissipates more slowly in hot weather. If the battery temperature
exceeds 230°F (110°C) during operation, the protection circuit will immediately turn off the mower to protect the battery pack from
heat damage. The power indicator on the mower will shine orange and the LED on the battery will flash red.
Release the bail handle, wait until the battery pack cools down to approximately 194°F (90°C), then restart the mower.
MOWING TIPS
NOTICE: A sharp blade will greatly enhance the performance of the mower, especially when cutting tall grass. Make sure to
check the sharpness of the blade before mowing.
1. Verify that the lawn is free of stones, sticks, wires, and other objects which could damage the lawn mower or motor. Such
objects could be accidentally thrown by the mower in any direction and could cause serious personal injury to the operator and
to others.
WARNING: If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower for any
damage, and repair the damage before restarting and operating the mower. Excessive vibration of the mower during operation is an
indication of damage. The unit should be promptly inspected and repaired.
For best results, do not mow in circles. Travel back and forth across the lawn.
When cutting thick grass, reduce your walking speed in order to allow for a more effective cut and a proper discharge of the
clippings.
To maintain a healthy lawn, cut off only one-third or less of the total length of the grass. The average lawn should be
approximately 1-1/2 to 2 inches long during cool months, and between 2 to 3-1/4 inches long during hot months.
SLOPE GAUGE (Fig. 9)
WARNING: Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2 1/2’ (0.75m) every 10’ (3m)).
Mow across the face of a slope and never up and down.
Use Fig. 9 as a guide in order to identify slopes that cannot be mowed safety.
MULCHING TIPS
WARNING: Inspect the area where the mower is to be used and remove all stones, sticks, wire and other debris that might
be thrown by the rotating blade.
Release the bail switch to stop the mower blade rotation when crossing any graveled areas; stones can be thrown by a rotating
blade.
Set the mower to the highest cutting height when mowing on uneven ground or in tall growth.
For effective mulching, do not cut wet grass; it tends to stick to the underside of the deck, preventing the proper mulching of
grass clippings. The best time to mow grass is in the late afternoon, when the grass is dry and the newly cut area will not be
exposed to direct sunlight.
For the best mulching performance, set the cutting height to remove approximately one third of the grass blade length, ideally
no more than 1 1/2” at one time. If the grass is overgrown, it may be necessary to increase the cut height to make it easier to
mow and to prevent overloading the motor. Slow your cutting pace in tall or thick grass conditions. For mulching extremely
thick or tall grass, it is advisable to first cut at a high cut-height setting, and then re-cut to the final cut height. Otherwise, make
narrower cuts and mow slowly. ALWAYS MAKE SURE THAT THE BLADE IS SHARP.
