GENERAL SAFETY RULES

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains- operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

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 ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

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 respiratory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of personal injury.
  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 energizing 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 jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry 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.

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains- operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.

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 the battery pack 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. 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. Use clamps to secure your workpiece to a stable surface. Holding a workpiece by hand or using your body to support it may lead to loss of control.

  9. KEEP GUARDS IN PLACE and in working order.

SERVICE

  1. Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

ELECTRICAL INFORMATION

DOUBLE-INSULATED TOOLS
The tool’s electrical system is double-insulated where two systems of insulation are provided. This eliminates the need for the usual three-wire grounded power cord. Double- insulated tools do not need to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are isolated from the internal metal motor components with protecting insulation.
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and should be done only by qualified service personnel using  identical replacement parts. Always use original factory replacement parts when servicing.

  1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only  one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the  machine plug or the extension cord in any way.
  2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power tool to reduce the risk of electric shock.
  3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician using original replacement parts.

GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in  loss of power and overheating. The table below shows the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

AMPERAGE REQUIRED GAUGE FOR EXTENSION CORDS
25 ft. 50 ft.
15A 14 gauge
  1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
    Always replace a damaged extension cord or have it repaired by a qualified person before using it.

  2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on plug. Disconnect the extension cord from the  receptacle before disconnecting the product from the extension cord.
    Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

  3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be protected with a 15A time-delayed fuse. Before connecting  the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor  nameplate. Running at a lower voltage will damage the motor.

At the same time, pull the switch handle  (Fig. 6 – 2) towards the upper handle with your other hand. The safety lock and the switch handle must be engaged at the same time for the machine to power ON.
  2. Release the safety lock button and use both hands to hold the switch handle and upper handle.

To power OFF the dethatcher / scarified:

  1. Gently release the switch handle and let the tines / blades come to a complete stop.

WEN DT1516 16 Inch Dethatched and Scarified - fig 8

WARNING! The tine cylinders continue to run after releasing the switch handle. DO NOT tilt or carry the unit while the tines are still in motion. Do not touch the cylinder  until it has come to a complete stop.

OVERLOAD PROTECTION
Your machine is equipped with overload protection and will activate in the following circumstances:
a. If there is a build-up of scarified materials around the cutting device.
b. If the scarified materials are larger than the motor capacity.
c. If there is too much resistance against the cutting device.
If the circuit breaker has been activated, switch the machine OFF and remove from the power source. Let the dethatcher / scarified cool down while determining the issue. Remove build-up or large materials before continuing operation.

GENERAL OPERATION

  1. Double check that the accessories are secure before beginning operation.

  2. Mark any sprinkler heads, lights, or other landscaping fixtures before beginning. Remove any hoses or other obstacles from the lawn.

  3. Push the machine forward by its handle.

  4. Make sure that all air vents are kept clean and unobstructed. Blocked air vents can lead to overheating.WEN DT1516 16 Inch Dethatched and Scarified - fig 9

  5. Make sure the lawn is clear of stones, sticks, wire, or other objects that could damage the machine.

  6. Do not work on a wet lawn.

  7. Slowly push the machine forward. Move the machine at an appropriate speed. Do not push the machine too hard.
    This can cause overload or blockage of discharge.

  8. Work in slight overlapping rows. The most effective pattern for scarifying / raking lawns is straight lines along one of the sides. This will keep the rows even and ensure that no areas are missed (Fig. 7).

SCARIFYING
Scarifying is more intense than dethatching. The blades reach down deep to remove moss, fungus, thatch, and other unwanted buildup from your lawn, while leaving the grass intact. At the same time, it scarifies (cuts grooves into) the ground, resulting in better drainage aeration for your lawn and, overall, better growth. Increase the depth setting in spring (April – May). The lawn is actively growing and will recover much better during this season. If the summer is wet, scarify again in late summer or early fall, using a  decreased depth setting. Do not scarify during periods of hot, dry weather. If the summer is very dry, do not scarify again in fall.

RAKING / DETHATCHING
Dethatching is less intense than scarifying, and does just what it sounds like – the steel tines reach down to pick up thatch and other light debris, resulting in better aeration  and drainage. When to dethatch varies; if your lawn is prone to thatch buildup (especially if you use a mulch setting on your lawnmower, or have certain species of grass),  you’ll need to dethatch more often. Choose a time when the grass is actively growing, and the soil has some moisture. In the northern half of the US, this will usually be in the  early spring or early fall. For the southern half of the US, this will usually be in late spring through early summer.

MAINTENANCE

ROUTINE INSPECTION
Before each use, inspect the tool. If any of these following conditions exist, do not use until parts are replaced.
Check for:

  • Loose hardware or improper mounting
  • Misalignment
  • Cracked or broken parts
  • Any other condition that may affect its safe operation

Once per season, lubricate the tines / blades and shaft. At the end of the season, check the dethatcher / scarifier for damage prior to storing. Repair or replace damaged or broken parts.
