applications, limitations, and possible hazards.
2. AVOID DANGEROUS CONDITIONS. DO NOT use in wet or damp areas or expose
to rain.
3. DO NOT use in the presence of flammable liquids or gases.
4. KEEP BYSTANDERS AT A SAFE DISTANCE. NEVER allow children near the tool.

adjustments, changing parts, or cleaning.
8. AVOID ACCIDENTAL START-UPS. Make sure the power switch is in the OFF
position before plugging in the power cord.
9. 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 fire hazard.
10. 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.
11. DO NOT OVERREACH. Keep proper footing and balance at all times.
12. DISCONNECT TOOLS. Disconnect tools from their power supplies when not in

WARNING:
Electrical Information
USE PROPER CIRCUIT PROTECTION TO AVOID THE RISK OF
ELECTRICAL SHOCK, FIRE OR DAMAGE TO THE TOOL. THE DETHATCHER IS
WIRED AT THE FACTORY FOR 120 V OPERATION. CONNECT TO A 120 V, 15 A
CIRCUIT AND USE A 15 A TIME-DELAYED FUSE OR CIRCUIT BREAKER.
REPLACE A CUT, WORN OR DAMAGED POWER CORD IMMEDIATELY TO
AVOID SHOCK OF FIRE.
WARNING:
TO AVOID INJURY, USE ONLY IDENTICAL REPLACEMENT
PARTS WHEN SERVICING THE DETHATCHER.
TOLL-FREE HELPLINE: 1-866-523-5218.
WARNING:
TO AVOID ELECTRIC SHOCK:
1. Use only identical replacement parts when servicing a tool with double insulation.
Servicing should be performed by a qualified technician.
2. Do not use in wet or damp areas or expose to rain.
WARNING:
DOUBLE INSULATION DOES NOT TAKE THE PLACE OF
NORMAL SAFETY PRECAUTIONS WHEN OPERATING THIS TOOL.
This dethatcher has a plug that looks like the one shown in Fig. 1.
The dethatcher is double insulated to provide a dual thickness of insulation between
you and the tool’s electrical system. All exposed metal parts are insulated from
internal motor components using protective insulation.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper
outlet installed by a qualified electrician.

Electrical Information
WARNING:
ALTHOUGH THIS TOOL IS DOUBLE INSULATED, THE EXTEN-
SION CORD AND OUTLET MUST STILL BE GROUNDED WHILE IN USE TO
PROTECT THE OPERATOR FROM ELECTRICAL SHOCK.
WARNING:
THIS DETHATCHER IS FOR OUTDOOR USE ONLY. DO NOT
EXPOSE TO RAIN OR USE IN DAMP LOCATIONS.
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 overheat-
ing. 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.
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 qualified techni-
cian 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.

Starting the Dethatcher:
• Plug the dethatcher into an approved outdoor extension cord.
• Press and hold the Power button (1). This makes the bale switch operational.
• Pull the bale switch (2) upward to the handlebar to operate.
Stopping the Dethatcher:
• Release the bale.
CIRCUIT BREAKER (Fig. 4)
This dethatcher is equipped with a circuit breaker in order to protect the supply circuit
from short-circuit overloads.
Follow these steps if the switch pops out:
1. Release the trigger switch, and allow the dethatcher to stop and cool down for a
minute.
2. Press the circuit breaker in order to reset it. Resume operation (See Figure 4).
Follow these steps if the switch pops out again shortly after the first time:
1. Allow the dethatcher to stop and cool down for 15 to 30 minutes.
2. After the dethatcher has cooled down, press the circuit breaker in order to reset it.
Resume operation.
If the circuit breaker does not stay in, or if it continues to pop out during operation,
contact the Toll-Free Helpline, at 1-866-523-5218.
IMPORTANT: Prior to dethatching the lawn, the lawn should be mowed to a
height of approx. 2" (0.05 m). Doing this will lengthen the life span of the tines and
prevent unnecessary motor overload on the dethatcher.
13
Operation and Adjustments
USING THE CORD RETAINER (Fig. 5)
Fig. 5
This dethatcher is equipped with a cord retainer in order to prevent the extension cord
from disconnecting from the power cord while the mower is in use. The cord retainer
hangs from the cord guide bar.
NOTE: Do not plug the extension cord into the outlet until it has been connected to the
cord retainer and plugged into the mower.
To use the cord retainer:
• Fold the extension cord in order to forming a tight loop near the retainer.
• Push the loop through the bottom hole in the retainer.
• Slide the loop over the retaining clip, and pull down until the cord is secured.

Operation and Adjustments
ADJUSTING THE DETHATCHER DEPTH (Fig. 6)
CAUTION: BEFORE YOU ADJUST THE DETHATCHER DEPTH, TURN OFF THE
POWER, UNPLUG THE TOOL AND ENSURE THE MOTOR HAS STOPPED.
1. The dethatcher depth is adjusted by turning the hubcaps. You can choose from
three different depth settings by pulling out and turning hubcaps.
2. When setting “I” is at the bottom, the high setting is locked in. The dethatcher
depth is approx 1 mm above the ground. Select depth setting “I” when transporting
the dethatcher.
3. When setting “II” is at the bottom, the middle setting is locked in. The dethatcher
depth is approx 1/8” (3 mm).
4. When setting “III” is at the bottom, the low setting is locked in. The dethatcher
depth is approx 3/8” (10 mm).
CAUTION: THE HUBCAPS MUST BE FIRMLY LOCKED INTO PLACE! AT THE
BEGINNING IT IS BEST TO SELECT DEPTH SETTING ”I” AT THE START. YOU
CAN THEN SWITCH TO SETTING "II" WHEN THE DETHATCHER SPIKES HAVE
BECOME WORN.
