WARNING

• The operation of any power tool can result in foreign objects being thrown into your eyes, which can result in severe eye damage. Before beginning power-tool operation,  always wear safety goggles or safety glasses with side shields and a full-face shield, when needed. We recommend using a wide vision safety mask over  eyeglasses or standard safety glasses with shields. Always use eye protection marked to comply with ANSI Z87.1.

• Some dust created by power cutting, 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 filter 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.

IMPORTANT SAFETY INSTRUCTIONS

**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 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.

• 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 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.

• 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 halfway 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 customer service.

• Use only with the battery packs and chargers listed below:

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.

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.

c. With the safety button depressed, pull the bail switch (A) upward to meet the handle and release the safety button.
d. The mower will start.

To stop the mower
a. Fully release the bail switch (A).
b. The electric brake will stop the blade rotation within 3 seconds of the bail switch release.

10 Variable-Speed Self-Propel System
The mower is equipped with variable-speed selfpropel capability.
This system is independent of the blade On-Off switch; it is not dependent on blade rotation. For example, when you have completed cutting your lawn, you can use the self- propel function to propel the mower back to your storage location with no blade rotation. Or you may choose to operate the mower as a non-self-propelled mower to maximize battery run time.
To operate the self-propel system without blade rotation, push the self-propel trigger (D) to the handle.
To turn the self-propel function off, release the self-propel trigger.

The system has variable speed. To increase the speed, move the self-propel- speed-control lever (O) forwards. To decrease the speed, move the self-propel speed-control lever  backwards.

To operate with the blade rotating for cutting:
a. Depress the safety button (D).
b. With the safety button depressed, pull the bail switch (A) upward to the handle and release the safety button.
c. Hold the bail switch against the handle with your left hand. Push the self- propel trigger (C) to the handle with your right hand.
d. With your right hand, hold both the bail switch and the self-propel trigger against the handle and use your left hand to adjust the self-propel speed- control lever (O) to  choose the desired speed.

When it is necessary to mow around an object, it may be easier to mow with the self-propel system turned off.
NOTICE: When you turn off the self-propel system, for example, at the end of a row, it may become temporarily locked if you pull backwards on the mower. Simply push  ahead slightly and then move the mower as required.

**WARNING**

• To reduce the risk of injury, never attempt to override the operation of the switch or selfpropel system. Use the self-propel system for its intended purpose only.

11. 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.

• 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
WARNING

• Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2 1/2’ (0.75 m) every 10’ (3 m)). Mow across the face of a slope and never up and down.

12. 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 switch to turn off 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.

CARE AND MAINTENANCE

WARNING

• All maintenance should only be carried out by a qualified service technician.
• Before cleaning or performing any maintenance, remove the battery pack. For safe and proper operation, always keep the tool and its ventilation slots clean.
• When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.
• Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If the operation is dusty, also wear a dust mask.
• Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken, or  destroy plastic, which may result in serious personal injury.

13. Cleaning
WARNING

• Always remove the battery pack when servicing or transporting the mower.
• When cleaning the mower, DO NOT immerse in water or other liquids.
  The underside of mower deck should be cleaned after each use, as grass clippings, leaves, dirt and other debris will accumulate. This accumulation is undesirable, as it will  promote rust and corrosion.
  Remove any build-up of grass and leaves on or around the drive shaft and motor fan (do not use water). Wipe the mower clean with a damp cloth.

14. Lubrication
Lubricate with light oil as directed below at least once each season.

• Periodically lubricate the spring and pivot pin in the quick-adjust handle, the torsion spring, and pivot of the rear-discharge door with light oil to prevent rust.
• Place the mower into the locked storage position, place the folded mower upright on the ground.
• Lubricate the deck-height adjustment joint.
• Lubricate the bearings on the drive shaft near the rear wheels and the bearings in the front wheels.

15. Removing the Blade

  e. Mount the bolt into the shaft and turn it clockwise by hand to re-tighten it.
  f. While still wearing protective gloves, hold the blade with one hand and turn the fan with the other hand to align the holes in the blade with the through holes in the  inner flange.
  g. Place a metal rod (e.g., a 3.5″ length screw bit) with diameter less than 1/4 inch (6.35mm) into the aligned holes to act as a stabilizer. Place another metal rod (e.g., a  3.5″ length screw bit) with diameter less than 5/16″ (8mm) into the fixing hole to act as another stabilizer.
  h. Use a 9/16-inch (14mm) torque wrench (not included) to tighten the bolt clockwise. The recommended torque for the blade bolt is 3643 ft-lb (49-59Nm).

17. Sharpening the Blade
WARNING

• Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other materials when performing any maintenance on the mower blade.  Always remove the battery pack when servicing or transporting the mower.
• Use proper eye protection while removing, sharpening, and installing the blade.
• A worn, cracked, or damaged blade can break, and pieces of the damaged blade can become dangerous projectiles. Thrown objects can cause serious injury. Inspect the  blade regularly and do not operate the mower with a worn or damaged blade.

NOTICE: Keep the blade sharp for best mower performance. A dull blade does not cut grass cleanly or mulch properly.
A dull blade can be sharpened, but a blade that is excessively worn, bent, cracked, or otherwise damaged must be replaced. A worn or damaged blade can break, causing blade pieces to be thrown from the mower.
If the blades are found to be bent, replace it.

Sharping Frequency
Sharpening the blade twice during a mowing season is usually sufficient under normal circumstances. Sand causes the blade to dull quickly; if your lawn has sandy soil, more frequent sharpening may be required.

When Sharpening the Blade:

• Make sure that the blade remains balanced.
• Sharpen the blade at the original cutting angle.
• Sharpen the cutting edges on both ends of the blade, removing an equal amount of material from each end.

To check the blade balance:
Clamp a nail or a screwdriver with a round shank in the horizontal position. Position the blade so that the nail or round shank of the screwdriver supports the blade through  its center hole.
Balance the blade horizontally. 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 drop.

**WARNING**
• An unbalanced blade will cause excessive vibration when rotating at high speeds. It may cause damage to the mower and could break, causing personal injury.

18. Replacing the Wheels
WARNING

• Always remove the battery pack when servicing or transporting the mower. We recommend having this carried out by an after-sales service provider.
  a. Turn the mower on its side with the upper surface against a wall.
  b. Use a flat blade screwdriver to pry the dust cover away from the wheel.
  c. Use an adjustable or ½-inch (13mm) wrench to turn the bolt counterclockwise to loosen it.
  d. For front wheel, remove the bolt, the worn wheel, the wave washer, and flat washer from the wheel axle.
  e. For rear wheel, separate the drive gear from the worn wheel by loosening and removing the screws. Save them for reassembling the new rear wheel.

NOTICE: During drive-gear mounting, the surface of the gear marked “out” should face toward outside (Fig. 18c).
f. Mount the wave washer and the new wheel on the wheel axle. Note that the round recess must face outward.
g. Lock the wheel with the bolt by tightening the bolt clockwise.
h. Mount the dust cover onto the wheel and press it into place.

19. Replacing the Trailing Shield
WARNING

• Always remove the battery pack when servicing or transporting the mower.
• Never operate the mower unless the trailing shield is in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal  injury. The trailing shield is subject to wear and damage, which could expose moving parts or allow objects to be thrown. For safety protection, frequently check the  trailing shield and replace it immediately with only the identical replacement part, listed in this manual. We recommend having this carried out by an after-sales service provider.

a. Remove the battery.
b. Turn the mower on its side with the upper surface against a wall.
c. Remove the rear wheel on the top side, following the section “Replacing the Wheels” in this manual.
d. Loosen the wheel-cover locking screw, then remove the wheel cover from the wheel shaft (Fig. 19a).
e. Repeat steps a to d above the remove the other rear wheel and the wheel cover.
f. Loosen the locking screw for the trailing shield (Q) on both sides; remove the worn trailing shield (Fig. 19b).
g. Replace with a new trailing shield and attach it with the two locking screws and flat washers.
h. Re-install the rear wheel covers and rear wheels; be sure to replace the parts in the exact order in which they were removed (Fig. 19c).

20. Transporting and Storing the Mower

• Do not store or transport the mower when it is running. Always remove the battery pack before storing or transporting.
• Before storing, clean the mower thoroughly as directed. Lubricate the mower as directed.
• Inspect the blade and replace it or sharpen it, if required.
• Store the mower at room temperature in a dry, clean location that is locked and/or inaccessible to children.
• Keep away from corrosive agents such as garden chemicals and de-icing salts.
• Do not cover the lawn mower with a solid, plastic sheet. Plastic coverings trap moisture around the mower, which causes rust and corrosion.

The handle can be folded away completely for storage:

a. Remove the grass bag.
b. Move the cutting-height-adjustment lever (R) toward the front and engage it in the lowest setting (setting 1).
c. Open the handle-locking clamps (E) and fully recess the side rails (N) to the compact position.
d. Pull and hold the quick-adjust handle with your right hand to release the handle. Gently pivot the handle toward the front of the mower; release the quick-adjust handle and continue to pivot the handle until you hear and feel the lock pin engage in the locked storage position.
e. Store the mower upright or flat.

WARNING
• If the mower to tips over from the upright position, mower damage or personal injury may result. Always keep the mower stable and out of the reach of children when it is  in the upright position. If possible, lay it flat for storage.
