• Do not abuse the power cord. Do not use it to carry the tool. Keep cord away from heat, oil,
sharp edges, or moving parts. Replace damaged cords immediately; they may create a shock
or re hazard.
• Never leave a running tool unattended. Turn the power switch to off. Do not leave the tool until
it has come to a complete stop.
• Do not overreach. Keep proper footing and balance at all times.
• Disconn ec t tools. Disconne ct tools from their power supplie s when not in us e, prio r to
servicing and when changing accessories such as blades, etc.
• Keep all safety devices in place.
• Know locations and functions of all controls.
• MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order.
• CHECK FOR DAMAG ED PARTS. Check for pr oper alignment of moving parts, binding,
breakage, o r any other conditions that may af fect the tool ’s o peration. Any par t t hat is
damaged should be properly repaired or replaced before use.

SPECIFIC SAFETY RULES
• Do not use the dethatcher in the rain or in moist, wet conditions.
• Do not work close to the edge of swimming pools or garden ponds.
• Please observe any local noise restrictions.
• Always wear eye protection.
• Wear a dust mask. Soil mixed with fertilizers may cause harmful chemicals to be inhaled.
• Extension Cord – To reduce the risk of disconnection of appliance cord from the extension
cord during operating, it is possible to tie the extension cord and power cord in a knot to
prevent them from becoming disconnected during use. Make the knot as shown in gure 1,
then connect the plug end of the power cord into the receptacle end of the extension cord. This
method can also be used to tie two extension cords together.
Fig. 1
• Make sure your extension cord is in good condition. When using an extension cord, be sure to
use one heavy enough to carry the current your product will draw. A wire gauge size (A.W.G.)
of at least 14 is recommended for an extension cord 50 feet or less in length. A cord exceeding
100 feet is not recommended mended. If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
• Wear hearing protection.
• Ensure that people and pets are at least 50’ (15 m) away from dethatcher while in use.
• Do not use the maximum dethatching depth setting, allow tines to wear down, start in the
highest setting and adjust as tines wear down.
• Replace worn or damaged parts only with identical replacement parts.
• Ensure that work area is free of slippery spots or excessive quantities of stone.
• Do not dethatch on slopes greater than 15 degrees.

GUIDELINES FOR USING EXTENSION CORDS
USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one of heavy enough gauge to carry the current
your product will draw. An undersized cord will cause overheating. The table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next
heavier gauge.The smaller the gauge number, the heavier the cord.
**Ampere rating (on tool faceplate)
MINIMUM GAUGE FOR EXTENSION CORDS (AWG)
(WHEN USING 120V ONLY)
Amp Rating Total Length of Cord in Feet (meters)
More Than Not More Than 25' (7.6 m) 50' (15 m) 100' (30.4 m) 150' (45.7 m)
0 6 18 16 16 14

Make sure your extension cord is properly wired and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a qualied technician before use. Keep extension
cords away from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for tools. This circuit should not be less than #12 wire and should
be protected with a 15 A 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.
W A R N I N G
KEEP THE EXTENSION CORD CLEAR OF THE TINES AND WORKING AREA. POSITION
THE CORD SO TH AT IT WILL N OT GET CAUGHT ON LUM BE R, TOOLS OR OTHER
