IMPORTANT
READ CAREFULLY BEFORE USE
KEEP FOR FUTURE REFERENCE
WARNING: Some dust created by power cutting 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 and cement and other masonry products, and
Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these
chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.

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 fire,
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.

8
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 15 years old to operate a power mower. Children 15 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 and for ordering
replacement parts.
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 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-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.

9
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.
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 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.
Mow only in daylight or good artificial 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.
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.
If situations occur that are not covered in this manual, use care and good judgment. Contact HENX 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 on page 22 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.

10
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,
listed in this manual.
If the mower’s built-in overload protection switch frequently trips, contact HENX Customer Service or your Closest service
center.
Do not wash the mower with a hose; avoid getting water in the motor and electrical connections.
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.
When servicing, use only identical replacement parts listed in this manual. Use of parts that do not meet the original
equipment specifications may lead to improper performance and compromised safety.
Remove or disconnect the battery pack before servicing, cleaning, or removing material from the lawn mower.
Follow instructions for lubricating and changing accessories.
Keep handles dry, clean and free from oil and grease.
To reduce a fire 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, as listed in this
manual.
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.
Always stop the motor before making adjustments to a wheel or a cutting-height adjustment.
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.
Maintain or replace safety and instruction labels, as necessary.
