WARNING
• Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to the State of California to cause cancer, birth defects
or other reproductive harm. Some examples of these chemicals are:
–Lead from lead-based paints.
–Crystalline silica from bricks, cement, and other masonry products.
–Arsenic and chromium from chemically-treated lumber.
• Your risk from these exposures varies, depending upon how often you do this type of work.
To reduce your exposure to these chemicals:
–Work in a well-ventilated area.
–Work with approved safety equipment, such as dust masks that are specially designed to
lter out microscopic particles.
–Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote
absorption of harmful chemicals.

SAFETY RULES FOR CORDLESS LAWN MOWER
DANGER This machine was built to be operated according to the rules for safe
operation included in this manual. As with any type of power equipment,
carelessness or error on the part of the operator can result in serious injury. This machine is
capable of amputating hands and feet and throwing objects. Failure to observe all safety
instructions could result in serious injury or death.
WARNING When using electric lawn mowers, basic safety precautions should always
be followed to reduce the risk of re, electric shock, and personal injury.
These basic precautions include the following:
Children
Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the mower and mowing activity. They do not understand the
dangers. Never assume that children will remain where you last saw them.
• Keep children out of the mowing area and under the watchful care of a responsible adult
other than the operator.
• Be alert and turn the mower off if a child enters the area.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects
that may obscure your vision of a child who may run into the mower.
• Never allow children under 14 years old to operate a power mower. Children 14 years old
and over should read and understand the operation instructions and safety rules in this
manual and should be trained and supervised by a parent. Only responsible individuals who
are familiar with these rules of safe operation should be allowed to use this machine.
Operation
General Operation:
• Read this operator’s manual carefully in its entirety before attempting to assemble this
machine. Read, understand, and follow all instructions on the machine and in the manuals
before operation. Be completely familiar with the controls and proper use of this machine
before operating it. Keep this manual in a safe place for future and regular reference.
• Use the right appliance – Do not use the lawn mower for any job except that for which it is
intended. Your lawn mower has been designed to perform only one job: to mow grass.
• Don’t overreach – Keep proper footing and balance at all times.
• Objects struck by the lawn mower blade can cause severe injuries to persons. The lawn
should always be carefully examined and cleared of all objects prior to each mowing.
• Keep the area of operation clear of all persons, particularly small children, and pets.
• Before and while moving backwards with the mower, look behind and down for small
children and other people.
• Keep clear of the discharge opening at all times.
• This machine is a precise piece of power equipment, not a plaything. Therefore, exercise
extreme caution at all times. Your unit has been designed to perform one job: to mow grass.
Do not use it for any other purpose.
• Don’t force the lawn mower – it will do the job better and more safely at the rate for which it
was designed.
• Thoroughly inspect the area where the equipment is to be used. Remove all stones, sticks,
wire, toys and other foreign objects that could be tripped over or picked up and thrown by
the blade. Thrown objects can cause serious personal injury.
• 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

4
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, 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-tting 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, rst look down and behind you to avoid tripping, and then
follow these steps:
– Step back from mower to fully extend your arms.
– Be sure you are well balanced with sure footing.
– 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 inuence 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.
• Mow only in daylight or good articial light. Walk, never run while operating.
• 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.
• 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.
• Always stop the motor before making adjustments to a wheel or a cutting-height adjustment.
• If situations occur that are not covered in this manual, use care and good judgment. Contact
SKIL Customer Service for assistance.

Operation On A Slope:
Slopes are a major factor related to slip-and-fall accidents, which can result in severe injury.
Operation on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For
your safety, use the slope gauge in this manual to measure slopes before operating this unit
on a sloped or hilly area. If the slope is greater than 15 degrees, do not mow it.
Do:
• Mow across the face of slopes; never mow up and down. Exercise extreme caution when
changing direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip.
Tall grass can hide obstacles.
Do not:
• Do not mow near drop-offs, ditches or embankments; you could lose your footing or balance.
• Do not mow slopes greater than 15 degrees, as shown on the slope gauge.
• Do not mow on wet grass. Unstable footing could cause slipping.
Service
WARNING Grass bag components, the discharge cover, side discharge chute,
mulching insert and trailing shield are subject to wear and damage, which
could expose moving parts or allow objects to be thrown and could increase the risk of injury.
For safety protection, frequently check all components and replace damaged components
immediately with identical replacement parts. Contact SKIL Customer Service for assistance.
• Remove or disconnect the battery pack before servicing, cleaning, or removing material from
the lawn mower.
• Do not wash the mower with a hose; avoid getting water in the motor and electrical
connections.
• Before cleaning the machine, 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. Then unclog the chute or remove or replace the grass
bag, or mulching insert.
• Follow instructions for lubricating and changing accessories.
• Keep handles dry, clean and free from oil and grease.
• To reduce a re hazard, keep the motor cover free of grass, leaves and debris build-up.
• Check the blade and motor mounting bolts at frequent intervals for proper tightness. Also,
visually inspect the blade for damage (e.g., bending, cracking and wear.). Replace the blade
only with the identical replacement blade.

• Maintain your mower with care – keep the mower blade sharp and clean for the best and
safest performance. Mower blades are sharp and can cut. Wrap the blade or wear gloves
and use extra caution when servicing it.
• Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
• Never remove or tamper with safety devices. Regularly check their proper operation.
Never do anything to interfere with the intended function of a safety device or to reduce the
protection provided by a safety device.
• After striking a foreign object, stop the motor, remove the battery pack, allow the blade to
stop rotating, and thoroughly inspect the mower for any damage. Repair the damage before
operating the mower.
• Remove the battery and store the idle lawn mower in a covered area when not in use. Allow
the motor to cool before storing it in any enclosure. The lawn mower should be stored in a
dry, high, or locked-up enclosure, out of reach of children.
• Maintain or replace safety and instruction labels, as necessary.
• Do not incinerate the appliance even if it is severely damaged. The batteries can explode in
a re.
• Do not expose a battery pack or tool to re or excessive temperature. Exposure to re or
temperature above 212 °F (100°C) may cause explosion.
• When servicing, use only identical replacement parts. Use of parts that do not meet the
original equipment specications may lead to improper performance and compromised
safety.
• SAVE THESE INSTRUCTIONS. Refer to them frequently and use them to instruct others
who may use this tool. If you lend this tool to someone else, also lend these instructions to
them to prevent misuse of the product and possibly injury.
