Lawn Mower Safety Warnings
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.
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 and Bystanders
Tragic accidents can occur if the operator is not alert to the presence of
children or bystanders.
• Keep the area of operation clear of all persons, particularly small children,
and pets.
• Use extreme care when approaching blind corners, doorways, shrubs,
trees, or other objects that may obscure your vision of a child or bystander.
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.
• Never allow children under 14 years old to operate a power mower.
Operators 14 years old and over should fully read and understand the
operator’s manual and safety rules. Only responsible individuals who are
familiar with these rules of safe operation should be allowed to use this
machine.
General Operation
• Read this operator’s manual carefully in its entirety before assembling or
operating this machine. Read, understand, and follow all instructions on
the machine and in the manuals before operation. Familiarize yourself with
the controls and proper use of this machine before operation. Save this
manual for future and regular reference.

SAFETY
• 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: cut grass.
• Never attempt to make a wheel height adjustment while the motor is
running.
• Don’t force the lawn mower; it will do the job better and more safely at the
rate for which it was designed.
• Don’t overreach, keep proper footing and balance at all times. Many
injuries occur as a result of the mower being pulled over the foot during
a fall caused by slipping or tripping. A slip and fall can cause serious
personal injury. If you feel you are losing your footing, release the control
handle immediately and the blade will stop rotating within three seconds.
• Thoroughly inspect the area where the mower is to be used and remove
all stones, sticks, wires, dog bones, and other foreign objects.
• Prevent unintentional starting. Ensure the switch is in the off position
before connecting to battery, picking up or carrying the mower. Carrying
the mower with your finger on the switch or energizing mower that has the
switch on invites accidents.
• 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:
1. Step back from the mower in order to fully extend your arms.
2. Be sure that you are well balanced.
3. Pull the mower back slowly.
• Remove the battery from the mower before making any adjustments,
changing accessories, or storing appliance. Such preventive safety
measures reduce the risk of starting the mower accidentally.
• Before and while moving backwards with the mower, look behind and
down for small children and other people.
• Do not operate the mower while under the influence of alcohol or drugs.
Stay alert and watch what you are doing at all times. Use common sense
and do not operate the lawn mower when you are tired.
• 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.
• Keep clear of the discharge opening at all times. Do not put hands or feet
near rotating parts or under the cutting deck. Contact with the blade can
amputate hands and feet.
• 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.

SAFETY
• To help avoid the blade or an injury from thrown objects, stay in the
operator zone behind the handles.
• A missing or damaged discharge cover can cause blade contact or injuries
from thrown objects.
• 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.
• Stop the blade when crossing gravel drives, walks or roads.
• Follow all charging instructions and do not charge the battery or mower
outside of the temperature range specified in the instructions. Charging
improperly or at temperatures outside of the specified range may damage
the battery and increase the risk of fire.
• If lawn mower strikes a foreign object, follow these steps:
1. Release the bail switch to disengage the motor.
2. Remove the battery.
3. Inspect for damage.
4. Repair any damaged parts before restarting and operating the lawn mower.
• Dress properly; do not wear loose clothing or jewelry that can be caught in
moving parts. Use of safety gloves and proper 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.
• Wear protective hair covering to contain long hair.
• Avoid dangerous environments; do not use the lawn mower in damp/wet
locations or if it is raining.
• Store idle lawn mower indoors. When not in use, appliances should be
stored indoors in dry, and high or locked-up places – out of reach of
children. Always remove the battery from the mower before storing.
• Mow only in daylight or good artificial light. Walk, never run while
operating.
• If the mower should start to vibrate abnormally, immediately stop the
motor, remove the battery and check for the cause. Vibration is generally a
warning that the mower is not functioning properly.
• Check bag frequently for deterioration and wear, and replace worn bags.
Check that replacement bags comply with the original manufacturer's
recommendations or specifications.
• Before cleaning the mower, unclogging or removing 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. The cutting
blade continues to rotate for a few seconds after the motor is shut off.
Never perform these functions until you are sure the blade has stopped
rotating.

DLM-2100

SAFETY
• Never operate the mower without the proper discharge cover, grass bag,
mulching insert, side discharge chute, or other safety devices in place and
working. Never operate the mower with damaged safety devices. Failure
to do so can result in personal injury.
• Use only ECHO eFORCE™ 56V series batteries and chargers. Other
batteries and chargers may cause damage to the mower or injure the
operator.
• Do not dispose of the battery in a fire. The cells could catch fire or explode.
Check with local codes and waste management for proper disposal
instructions.
• When battery is not in use, keep it away from other metal objects, like
paper clips, coins, keys, nails, screws or other small metal objects that
can make a connection from one terminal to another. Shorting the battery
terminals together may cause burns or a fire.
• Do not open or destroy the battery. Electrolytes contained within the
battery are corrosive and may cause damage to eyes or skin if released. It
may be toxic if swallowed.
• Under abusive conditions, liquid may be ejected from the battery; avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejected from the battery may
cause irritation or burns.
• Do not expose a battery or appliance to fire or excessive temperature.
Exposure to fire or temperature above130°C may cause explosion.
• Exercise care in handling batteries to avoid shorting the battery with
conducting materials such as rings, bracelets, keys, etc. The battery or
conductor may overheat and cause burns if contact with said materials is
made.
• Do not use a battery or appliance that is damaged or modified. Damaged
or modified batteries may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
Service/Maintenance
• Check the blade and the motor (machine) mounting bolts at frequent
intervals for proper tightness.
• Replace the blade if it is bent or cracked. An unbalanced blade causes
vibration that could damage the motor drive unit or cause personal injury.
• Keep all nuts, bolts, and screws tight in order to ensure the equipment is
in safe working condition.
• Do not wash with a hose; avoid getting water in motor and electrical connections.
• Never remove or tamper with safety devices. Check their proper operation
regularly. Never do anything to interfere with the intended function of a
safety device or to reduce the protection provided by a safety device.
• Keep mower free of grass, leaves, or other debris build up. Allow mower to

cool before storing.
• Never make any adjustments or repairs with the motor running.
• Always remove battery from mowers before adjusting, cleaning, or repairing.
• Check grass catcher components and the discharge guard frequently and
replace with manufacturer’s recommended parts, when necessary.
• Sharpen a dull blade equally at each end to maintain the balance.
• Keep guards in place and in working order. Mower blades are sharp, and can
cut. Wrap the blades or wear gloves, and use extra caution when servicing.
• Clean the blade thoroughly and check its balance by supporting it
horizontally on a thin nail through its center hole. The nail should also be in
a horizontal position. If either end of the blade rotates downward, remove
some metal from the heavy or lower end until the blade is balanced. It is
balanced when neither end drops.
• Use identical replacement blades only.
• Maintain lawn mower with care. Keep cutting edges sharp and clean
for best and safest performance. Follow instructions for lubricating and
changing accessories. Inspect lawn mower cord periodically and if
damaged, have it repaired by an authorized service facility.
• If situations occur that are not covered in this manual, use care and good
judgment or contact Customer Service for assistance.
• Never operate the mower without proper guards, plates, or other safety
protective devices in place.
• Before each use, examine the machine for damaged, missing, or loose
parts such as screws, nuts, bolts and caps.
• Tighten correctly all the fasteners and caps.
• Clean the machine with a dry cloth. Do not use water.
• Have servicing performed by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the product is
maintained.
• Do not modify or attempt to repair the mower or the battery (as applicable)
except as indicated in the instructions for use and care.
• Never service damaged batteries. Service of batteries should only be
performed by the manufacturer or authorized service providers.

Slope Operation
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.
Do:
• Mow across the face of slopes; never mow up and down. Exercise
extreme caution when changing direction on slopes.
• Watch for holes, roots, rocks, hidden objects, or bumps which can cause
you to slip or trip. Tall grass can hide obstacles. Remove all obstacles
such as rocks and tree limbs.
• Make sure that your footing is stable. If you have lost your balance,
release the switch immediately.
Do not:
• Mow near drop-offs, ditches or embankments; you could lose your footing
or balance.
• Mow slopes greater than 15 degrees.
• Mow on wet grass. Unstable footing could cause slipping.
If you are not comfortable, do not mow on a slope.

OPERATION
Operation Tips
• Do not try to override the operation of the start button or start handles.
• Do not tilt the machine when you start it.
• Do not put hands or feet near or below the turning parts.
• Keep the discharge chute clean.
• Cutting wet grass will require more power, shorten run time and cut grass
poorly.
• Higher blade height is necessary for new or thick grass.
• Clean the bottom of the mower deck after each use. Remove grass
clippings, leaves, dirt, and other debris.
• Mulching requires a higher mower deck setting than bagging or side
discharge. Adjust wheel height to remove roughly one-third off top of
grass.
Your unit is designed to provide many hours of trouble free service. Regular
scheduled maintenance will help your unit achieve that goal. If you are unsure
or are not equipped with the necessary tools, we recommend that you take
your unit to a Servicing Dealer for maintenance. To help you decide whether
you want to DO-IT-YOURSELF or have the Dealer do it, each maintenance
task has been graded. If the task is not listed, see your Dealer for repairs.
MAINTENANCE
Moving parts can amputate ngers or cause severe injuries.
Keep hands, clothing and loose objects away from all openings.
Always stop motor, and make sure all moving parts have come to
a complete stop before removing obstructions, clearing debris, or
servicing unit. Allow unit to cool before performing service. Wear
gloves to protect hands from sharp edges and hot surfaces.
Operating a poorly maintained unit can result in serious injuries
to operator or bystanders. Always follow all maintenance
instructions as written, otherwise serious personal injury can
result.
