Step 1 |

Determine where to make injections and what length of Wedgle Tip to use. Generally, the short (.75") Wedgle Tip is used, except for trees with thick, corky bark such as Hemlocks, Eucalyptus, Cottonwoods, or Elms which require the long (1.5") Wedgle Tip.
To determine the thickness of the bark, slowly and gently insert a short Wedgle Tip in a fissure (valley) of the bark until you feel the resistance of the tip as it reaches the wood. Before you withdraw the tip, note how deep the tip has penetrated into the bark with your fingertip. If the tip penetrates more than the length of a WedgeChek, injections should be made in the fissure of the bark. It is preferable to make injections in fissures as long as the bark in those areas is at least as thick as the length of a WedgeChek. If the Wedgle Tip penetrates less than the length of a WedgeChek, injections should be made in a thicker part of the bark. If you do not feel the tip reach the resistance of the wood, switch to the long Wedgle Tip. |

Step 2 |

  With a straight firm motion insert the WedgeChek Punch into the tree, and then rotate the punch in a clockwise and counterclockwise motion to cut a small bark core from the tree. Remove the punch and squeeze the trigger to remove the bark core from the punch. Examine the core to make sure it is approximately the same length as the WedgeChek.
Place the WedgeChek on the protruding pin on the bottom of the grip, then insert the WedgeChek directly into the punched hole until the flange is flush with the outer bark of the tree. The barbs on the WedgeChek will secure it in the tree. On thin-barked trees, do not be concerned if the WedgeChek sticks out. |

Step 3 |
|
| |
 With a straight motion, gently slide the Wedgle Tip through the WedgeChek. As the tip is pushed through the WedgeChek and the bark, the blunt-edged tip automatically stops when it reaches the wood. This insertion will usually be no more than one-quarter to three-quarters of the length of the Wedgle Tip. Do not force the tip into the hardwood of the tree. Only moderate hand pressure is needed. |

Step 4 |
|
| |
With a smooth motion, firmly squeeze both handles at the same time. This releases a pre-measured dose of chemical at the edge of the tree’s outer layer of the xylem where it can easily be absorbed by the tree.
Slowly slide the Wedgle Tip out of the tree. The self-sealing WedgeChek plugs the hole. Repeat these steps while moving around the flare of the tree. Be sure to follow the label directions to determine how many injection sites are needed on any given tree. Tree growth will eventually push the WedgeCheks out. |

|
| |
The ArborSystems Wedgle Direct-Inject unit is preset to release a 1 ml dose of chemical with each full stroke of the handles. If you desire to inject a 1/2 ml dose of chemical, move the dose adjustment ring to the 1/2 ml dose adjustment groove (see parts illustration #52). This will limit the handle stroke so the unit will release a 1/2 ml dose of chemical. |

 The cross section photo shows how the wood absorbs the chemical that is injected. (Colored water is used for illustration purposes only.) The outer layer of the wood is the only area where the chemical can actively be transferred to other parts of the tree. Because of this, the ArborSystems Wedgle Direct-Inject Tree Treatment System can be more effective with significantly less chemical. Since no air is allowed to enter the tree, the chance of damage from decay fungi is essentially eliminated.
