the bolts (Fig. 2).
4. Tighten the knobs to secure the handlebars in place.
NOTE:
Do not over-tighten the knobs.

switch assembly (Fig. 1, Inset A).
NOTE:
Take care not to pinch the switch cable when
positioning the handlebars.
6. Clip the switch cable to the cable restraint on the lower
bar as shown in Figure 1, Inset B.
USING THE CORD RETAINER
There is an extension cord re tainer to prevent the extension
cord from disconnecting during use. The retainer hangs
from the cord guide bar.
NOTE:
Do not plug the extension cord into the power
source receptacle until the cord is connected to
the cord retainer and plugged into the unit.
To use the cord retainer:
1. Fold the extension cord in half, forming a tight loop near
the receptacle.
2. Push the loop through the bottom hole in the retainer (Fig. 3).
3. Slide the loop over the retaining clip and pull down until
the cord fits snugly (Fig. 4).
NOTE:
Use a UL-approved extension cord. A 100-foot,
14-gauge cord is recommended. A 50-foot, 16-
gauge cord is acceptable.
The cord retainer keeps the extension cord safely to the
side of the operator by sliding to the left and right on the
guide bar as --the unit is moved. Connect your extension
cord to the unit as shown in Figure 5.
STARTING AND STOPPING INSTRUCTIONS
STARTING INSTRUCTIONS
WARNING:
Avoid accidental starting. Make
sure you are in the operating position behind
the cultivator when using it. To avoid serious
injury, the operator and unit should be in a
stable position while starting.
Connecting to an Electrical Power Source
NOTE:
Connect your extension cord to the cultivator as
instructed on the previous page prior to plugging
your extension cord into an electrical outlet.
1. Plug your extension cord into any convenient (indoor or
outdoor) 120-volt, 60-cycle AC grounded outlet or
receptacle. Your cultivator will operate satisfactorily on a
circuit with a 15 ampere breaker.
NOTE:
To avoid tripping circuit breakers, select an outlet
on a circuit that is not overloaded. Do NOT select
an outlet that is on a circuit hosting appliances
such as a refrigerator.
2. Stand behind the cultivator, in the operating position.
3. Pivot the cultivator slightly toward the rear, so that its
weight is resting on the wheels and the tines are NOT in
contact with the ground
4. Depress the (red) starter button and hold it in (Fig. 6, no. 1).
NOTE:
Starting the cultivator's motor also starts tilling action.
5. While holding the starter button in, pivot the bail upward against the handle bar (Fig. 6, no. 2) to
start the motor and engage the tines.
NOTE:
The cultivator's motor will NOT start if you fail to hold the starter button in while pivoting the
bail upward.
6. Release the (red) starter button and grasp the handle and bail together with both hands (Fig. 7).
STOPPING INSTRUCTIONS
1. Release the bail.
2. The starter button will pop out, the bail will pivot downward and the motor will stop.
OVERLOAD PROTECTION SWITCH
This cultivator is equipped with an overload protection switch to prevent overheating damage to the
motor. If the overload protection switch pops out:
1. Release the bail and do NOT re-start the cultivator for at least one minute, allowing for the electric
motor time to cool.
2. Press the overload protection switch inward to reset (Fig. 6, no. 3).
If the overload protection switch pops out shortly after resetting:
1. Release the bail and do NOT re-start the cultivator for at least 15 minutes to allow the electric
motor extra time to cool.
2. Press the overload protection switch inward to reset.
3. Restart unit.
NOTE:
If the overload protection switch pops out repeatedly during operation or will not remain in
when attempting to reset, contact the Customer Support Department to arrange for repair.
