SAFETY WARNINGS

General power tool safety warnings

⚠ WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

1. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

5. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

6. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

7. Use of power supply via an RCD with a rated residual current of 30 mA or less is always recommended.

8. Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.

9. Do not touch the power plug with wet hands.

10. If the cord is damaged, have it replaced by the

manufacturer or his agent in order to avoid a safety hazard.

Personal safety

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

2. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.

3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

4. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

8. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

9. Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, it is legally required to wear a face shield to protect your face, too.

It is an employer's responsibility to enforce the use of appropriate safety protective equipments by the tool operators and by other

persons in the immediate working area.

Power tool use and care

1. Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
2. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
5. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
8. Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
9. When using the tool, do not wear cloth work gloves which may be entangled. The entanglement of cloth work gloves in the moving parts may result in personal injury.

full, empty the grass basket before starting mowing.

▶ Fig.16: 1. Level indicator
▶ Fig.17: 1. Level indicator

Adjusting the handle height

The handle height can be adjusted in three levels. Loosen the thumb nuts while holding the handle, then adjust the handle height by aligning the arrow with one of the marks, and then tighten the thumb nuts.
▶ Fig.18: 1. Thumb nut 2. Mark 3. Arrow

Motor protection system (Over current relay)

WARNING: If the machine suddenly stops while operating it, release the switch lever and unplug the extension cord. Otherwise, the machine may suddenly restart and cause an injury.
CAUTION: Before removing an object that is jamming the blade, be sure to wear gloves and unplug the extension cord from the power socket.

If the cut off grass or dirt is jamming inside of the main body, the machine stops automatically to protect the motor (over current relay). In this case, unplug the extension cord from the power socket, then remove the material causing the jam, and then let the machine cool down for a few minutes before turning on the machine.

NOTE: The over current relay may be activated when wet or long grass gets caught up inside of the main body.

OPERATION

Mowing

WARNING: Before mowing, clear away sticks and stones from the mowing area. Furthermore, clear away any weeds from the mowing area in advance.
▶ Fig.19
WARNING: Always wear the safety goggles or safety glasses with side shields when operating the mower.
CAUTION: If the cut grass or foreign object blocks up inside of the mower body, be sure to turn the power off, and then unplug the extension cord from the power socket. Before removing the grass or foreign object, be sure to wear gloves.
⚠️ CAUTION: Be sure to install the grass basket when operating the machine.
NOTICE: Use this machine for mowing lawn only. Do not mow weeds with this machine.

Firmly hold the handle with both hands when mowing.

▶ Fig.20

The mowing speed guideline is approximately one meter per four seconds.

▶ Fig.21

Start mowing near the power socket to ensure that the extension cord does not become an obstacle.

▶ Fig.22: 1. Power socket 2. Extension cord

Do not allow the extension cord to pass under or become entangled beneath the machine.

▶ Fig.23

▶ Fig.24

The lines on both sides of the main body are guidelines to mowing width. Using the lines as guidelines, mow in strips. Overlap by one half to one third the previous strip to mow the lawn evenly.

▶ Fig.25: 1. Mowing width 2. Overlapping area 3. Line

Change the mowing direction each time to prevent the grass grain pattern from forming in just one direction.

▶ Fig.26

Periodically check the grass basket for mowed grass. Empty the basket before it becomes full. Before every periodic check, be sure to stop the machine.

NOTE: Using the mower with the grass basket full prevents smooth blade rotation and places an extra load on the motor, which may cause a breakdown.

Mowing a long-grass lawn

Do not try to cut long grass all at once. Instead, mow the lawn in steps. Leave a day or two between mowings until the lawn becomes evenly short.

▶ Fig.27

NOTE: Mowing long grass to a short length all at once may cause the grass to die. The cut grass may also block up inside of the mower body.

Edge mowing

When mowing at the edge, be sure to move the machine along the edge.

▶ Fig.28

MAINTENANCE

WARNING: Before performing the maintenance, unplug the extension cord from the power supply, and confirm that the blades have come to a complete halt.
