General Safety WARNINGS!

When using this electric dethatcher, basic safety precautions should always be followed to reduce the risk of fire, electric shock and personal injury.

Before using the dethatcher, take the time to familiarize yourself with the controls, especially how to stop the dethatcher in an emergency. The only individuals who should use the dethatcher are those who have a thorough understanding of the instructions and who know how to operate the machine. Children should never be allowed access to the dethatcher.

Retain this manual for future reference and reread it at the start of each dethatching session.

General Safety

1. Avoid dangerous conditions – Do not use this machine

2. Stay alert – Always be alert and watch what you are doing. Use common sense. Do not operate the dethatcher when you are tired or under the influence of alcohol or drugs.

3. Disconnect the dethatcher – Disconnect the dethatcher from the power supply when it is not in use, before servicing it, when changing accessories and when performing any other maintenance task.
4. Store idle dethatcher indoors – When not in use, the dethatcher should be stored indoors in a dry, locked place out of the reach of children.
5. Maintain the dethatcher with care - Keep cutting edges sharp and clean for optimal and safest performance. Inspect the dethatcher cord periodically and if damage is found have it repaired by an authorized service facility. Extension cords should also be inspected periodically and immediately replaced if damaged. Keep handles dry, clean and free from oil and grease.
6. Double insulation - This dethatcher is equipped with double insulation. This means that all external metal parts are insulated from the electrical supply. This is achieved by introducing an insulation layer between electrical and mechanical parts. The double insulation guarantees you the greatest possible safety.

Electrical Safety

1. Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the dethatcher. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
2. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A, or SJTOW-A.
   Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current to the product. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

WARNING

Electric shock may cause SEVERE INJURY or DEATH. Heed these warnings:

• Do not allow any part of the electric dethatcher to make contact with water while it is in operation. If the appliance becomes wet while turned off, wipe dry before starting.
• Use only a UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use.
• Do not use an extension cord over 100 ft (30 m).
• Do not touch the appliance or its plug with wet hands or while standing in water. Wearing rubber boots offers some protection.

Safety Instructions for Walk-Behind Dethatchers

General Operation

• Read, understand and follow all instructions on the machine and in the manual(s) before starting.
• Thoroughly inspect the area where the equipment is to be used and remove all foreign objects.

⚠ WARNING! Foreign objects in the work area can be picked up by the dethatcher and launched into your eyes, which can result in severe personal injury. In addition to surveying the area and removing foreign objects before beginning work, always wear safety goggles or safety glasses with side shields and, when necessary, a full face shield.

• Do not operate the equipment without wearing adequate outer garments. Wear protective footwear that will improve footing on slippery surfaces.
• Use extension cords and receptacles as specified by the manufacturer for all units with electric drive motors or electric starting motors (see extension cord chart on page 2).
• Never attempt to make any adjustments while the motor is running.
• Do not put hands or feet near or under rotating parts.
• Exercise extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for hidden hazards or traffic.
  • After striking a foreign object, stop the motor, disconnect the power supply, thoroughly inspect the machine for any damage and repair the damage before restarting and operating the machine.
  • Exercise caution to avoid slipping or falling.
• If the dethatcher should start to vibrate abnormally, stop the motor, disconnect the power supply and check immediately for the cause. Vibration is generally an indicator of trouble.

• Stop the motor and disconnect the power supply when leaving the operating position, before unclogging the tines and when repairing, adjusting, inspecting or performing any other maintenance on the machine.
  • Take all necessary precautions when leaving the machine unattended. Stop the motor and remove the power cord.

• Use extreme caution when reversing or pulling the machine towards you.

• Switch on the motor carefully according to the instructions and keep your feet clear of the rotating tines.
• Never pick up or carry the machine while the motor is running.

Children Safety

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the dethatching activity. Never assume that children will remain where you last saw them.

• Keep children out of the dethatching area and under the watchful care of a responsible adult other than the operator.
• Stay alert and turn the dethatcher off if a child enters the area.
  • Never let children operate the machine.
• Use extra care when approaching blind comers, shrubs, trees or other objects that may block your view of a child.

Operation

Setting the Working Positions (Using the tine depth control knob)

NOTE: Before dethatching your lawn, prep the area by mowing the lawn to a height of approximately 2 in. (5 cm). This will minimize tine wear and prevent unnecessary motor overload.

The dethatcher has 5 principal position settings:

Setting 0 (+9 mm): Transport position

This position sets the maximum safety spacing between the tool and the floor.

Setting 1 (+6 mm): Working position

Set this position when working with a new implement.

Settings 2 – 4 (+3 mm, 0 mm, -3 mm, respectively): Readjustment positions

The working position can be lowered with increased spring tine wear. The readjusting depth amounts to approximately 3 mm per setting. Use the millimeter scale readings for fine setting.

NOTE: When the unit is delivered it is in the transport position (setting 0).

⚠️CAUTION! The unit must be switched off and disconnected from the power supply before adjusting the time settings.

Press the adjustment knob down and turn it to the required position until it locks in place (the knob will immediately rise after it is locked into a setting) (Fig. 3).

Starting + Stopping

⚠ WARNING! Before switching on the dethatcher, make sure that it is not in contact with any foreign objects. Keep your feet and hands a safe distance away from the rotating tines and the ejector opening. Failure to comply with these warnings can result in severe personal injury.

1. Place the unit on a level lawn surface.
2. Form a loop with the end of the extension cord, push the loop through the hole in the cable relief holder and slide the loop onto the retaining clip to secure the extension cord (Fig. 4).

Overload Protection

The motor is automatically switched off when the unit is overloaded. Release the switch bar lever and the unit will reset after a cool down period of approximately 1 minute.

Working with the Unit

Dethatching your lawn is an intensive intervention and should only be carried out once a year. For cool-season grasses, the best time to dethatch is late summer or early fall. For warm-season grasses, dethatch in late spring or after the second mowing. Before dethatching, mow a little shorter than normal.
