WARNING
When using electric lawn mowers, basic safety precautions should always be followed to
reduce the risk of re, electric shock, and personal injury, including the following:
1. GENERAL OPERATION
• When servicing use only identical replacement parts.
• Avoid Dangerous Environment – Don’t use lawn mowers in damp or wet locations
• Don’t Use In Rain
• Keep Children Away – All visitors should be kept a safe distance from work area.
• Dress properly. Do not wear loose clothing or jewelry that can get caught in moving parts.
The wearing of protective gloves and safety footwear is recommended.
• Use Safety Glasses – Always use face or dust mask if operation is dusty.
• Use Right Appliance – Do not use lawn mower for any job except that for which it is
intended.
• Don’t Force Lawn Mower – It will do the job better and safer at the rate for which it was
designed.
• Don’t Overreach – Keep proper footing and balance at all times
• Stay Alert – Do not operate the mower when you are tired. Pay attention to what you are
doing. Use common sense.
• Store Idle Lawn Mower Indoors – When not in use, lawn mower should be stored in an
indoor dry and locked-up place – out of reach of children.
• 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.
• Keep handles dry, clean, and free from oil and grease.
• Keep safety devices (guards, shields, switches etc.) in place and working.
• Keep blades sharp.
• Keep hands and feet away from cutting area.
• 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.

4
IMPORTANT SAFETY INSTRUCTIONS
• If lawn mower strikes a foreign object, follow these steps:
i) Stop lawn mower. Release the switch.
ii) Remove battery.
iii) Inspect for damage.
iv) Repair any damage before restarting and operating the lawn mower.
• Use identical replacement blades only.
• Do not charge lawn mower in rain, or in wet locations.
• Remove or disconnect battery before servicing, cleaning, or removing material from
the lawn mower.
• Use only with Greenworks batteries: GL 200/GL 250/GL 300/GL 400/GL 500/GL 900
• Use only with Greenworks Chargers: GC 400
• Do not dispose of the battery in a re. The cell may explode. Check with local codes for
possible special disposal instructions.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause
damage to the eyes or skin. It may be toxic if swallowed.
• Exercise care in handling batteries in order not to short the battery with conducting
materials such as rings, bracelets, and keys. The battery or conductor may overheat and
cause burns.
• Read, understand, and follow all instructions on the machine and in the manual(s) before
starting.
• Only allow responsible adults who are familiar with the instructions to operate this
machine.
• Clear the area of objects such as rocks, wire, toys, etc., which could be thrown by the
blade. Stay behind the handle when the engine (motor) is running.
• Be sure the area is clear of bystanders before operating. Stop machine if anyone enters
the area.
• Do not operate machine barefooted or while wearing sandals. Always wear substantial
footwear.
• Do not pull machine backward unless absolutely necessary. Always look down and
behind before and while moving backward
• Never direct discharged material toward anyone. Avoid discharging material against a wall
or obstruction. Material may ricochet back toward the operator. Stop the blade when crossing
gravel surfaces.
• Do not operate machine without the entire grass catcher, discharge guard, rear guard,
or other safety protective devices in place and working.
• Never leave a running machine unattended.
• Stop the motor and wait until the blade comes to a complete stop before removing the
grass catcher or unclogging the chute.
• Operate machine only in daylight or good articial light.
• Do not operate machine while under the inuence of alcohol or drugs.

5
IMPORTANT SAFETY INSTRUCTIONS
• Never operate mower in wet grass. Always be sure of your footing; walk, never run.
• Disengage the drive system, if so equipped, before starting the motor.
• If the machine should start to vibrate abnormally, stop the motor and check for the
cause immediately. Vibration is generally a warning of trouble.
• Always wear eye protection when operating machine.
• See manufacturer’s instructions for proper operation and installation of accessories.
Only use accessories approved by the manufacturer.
2. SLOPE OPERATION
• Slopes are a major factor related to slip and fall accidents, which can result in severe
injury. Operation on all slopes requires extra caution. If you feel uneasy on a slope, do not
mow it.
• Mow across the face of slopes; never up and down. Exercise extreme caution when
changing direction on slopes.
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could cause
a slip and fall accident. Tall grass can hide obstacles.
• Do not mow on wet grass or excessively steep slopes. Poor footing could cause a slip
and fall accident.
3. CHILDREN
Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the machine and the mowing activity. 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.
• Stay alert, and turn the mower off if a child or any other person enters the mowing
area.
• Never allow children to operate the machine.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other
objects that may obscure your view of a child who may run into the path of the mower.
4. SERVICE
• Keep all nuts, bolts, and screws tight in order to be sure that the equipment is in safe
working condition.
• 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 machine free of grass, leaves, or other debris build up. Allow machine to cool before
storing.
• After striking a foreign object, stop the motor. Thoroughly inspect the mower for any
damage. Repair any damage before operating the mower.
• Never make any adjustments or repairs with the motor running.
• Always remove battery pack from mowers before adjusting, cleaning, or repairing.
