GENERAL SAFETY RULES
WARNING:
READ AND UNDERSTAND ALL INSTRUCTIONS. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious personal injury.
READ THESE INSTRUCTIONS
n iar with the controls and the proper use of the equipment.
Know how to stop the unit and disengage the controls quickly.
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.
Double insulated tools are equipped with 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 polarized outlet.
Do not change the plug in any way. Double insulation eliminates the need for the three-wire grounded power cord and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
Use outdoor extension cords marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.
n allow adults to operate the equipment without proper instruction.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual threewire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded.
WARNING:
The double insulated system is intended to protect the user from shock resulting from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid electrical shock.
NOTE: Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the tool to your nearest authorized service center for repair. Always use original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC
only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If your tool does not operate when plugged into an outlet, double-check the power supply.
GFCI
Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the cultivator. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
EXTENSION CORDS
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a tool, use an extension cord that is designed for outside use. This type of cord is designated with “WA” on the cord’s jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

OPERATION
GENERAL CULTIVATING
See Figure 10.
Shallow cultivating less than 2 in. deep can be used to disrupt weeds and aerate soil, without injuring nearby plant roots. It should be done often so that weeds do not grow large and cause tangling in the tines of the unit.
The two outer tine blades can be removed from the unit to allow a more narrow cultivating width.
To remove the two outer tines: n Unplug the cultivator.
n Remove the hitch pins from the holes on the ends of the tine shaft.
n Remove the outside tine blades and felt washers from the tine shaft. n Place hitch pins in the holes that were uncovered when felt washers were removed.
