NOTE: The unit will not operate properly if the tines are 
installed incorrectly. If you notice a problem with the cultivat-
ing operation of the unit, check for proper tine positioning.

Wear heavy gloves when installing, removing, or adjust-
ing the tiller tines. With wear, the tiller tines may become 
sharper.

See Figure 3.
The tiller attachment connects to the power head by means 
of a coupler device.

Never attach or adjust any attachment while power head 
is running. Failure to stop the engine or motor may cause 
serious personal injury.

To install the attachment:


  Remove the spark plug wire or disconnect from the power 

supply.



  Remove the hanger cap from the attachment. 



  Loosen the knob on the coupler of the power head 

shaft.

  Push in the button located on the shaft of the tiller attach-

ment.

  Align the button with the guide recess on the power head 

coupler and slide the two shafts together. Rotate attach-
ment shaft until button locks into the positioning hole.

 

NOTE: If the button does not release completely in the 
positioning hole, the shaft is not locked into place. Slightly 
rotate from side to side until the button is locked into 
place.

  Tighten the knob securely.

Be certain the knob is fully tightened before operating 
equipment; check it periodically for tightness during use 
to avoid serious injury.

To remove:
  Stop the engine or motor and remove the spark plug wire 

or disconnect from the power supply.

  Loosen the knob.
  Push in the button and twist the shafts to remove and 

separate ends.

See Figure 4.
The J-handle included with the tiller attachment provides a 
barrier to assist the operator in maintaining a safe distance 
from the rotating tines. If the power head to which the tiller 
attachment will be mounted does not have such a handle, 
install the provided handle.


  Hold the top and bottom clamp snugly in position on the 

shaft housing so that handle will be located to the opera-
tor’s left.



  Insert the end of the handle between the clamps.



  Align the bolt holes and push the long bolt (1/4-20 x 1-1/2 

in.) through the handle side.



  Place short bolt (1/4-20 x 1 in.) through opposite side of 

clamp. Install flat washers, lock washers, and hex nuts 
to hold the assembly in place.



  After assembly is complete, adjust the position of the 

handle for best balance and comfort.



  Tighten the long bolt first and then the short bolt.
