Conifers and palms are treated using the Direct-Inject QC™ injection unit with Portle® or Palm Tips and the Tip Setter. The Tip Setter is used to drive the injection tips deep into the active areas of these trees. Because of the depth of the injection, Wedge-Cheks are not used. Portle and Palm Tips and the Tip Setter are sold separately.
|
| |
Step 1: Attach a Portle Tip or Palm Tip to the Tip Setter. |
| |
The Tip Setter uses a QC coupler to hold the injection tips in place. Slide back the coupler, insert the hub end of a tip, then release to secure the tip in the setter. |
| |
Step 2: Tap the injection tip into the tree. |
| |
using the sliding action of the Tip Setter. Place the tip against the bark, selecting a location where the bark is firmly adhered to the tree. Place yourself directly behind the setter, keeping the rear of the setter perpendicular to the tree. Grasp the slide. Beginning gently, then with increasing force, tap the tip into the tree until the front of the hub is in tight contact with the bark.
When inserting or removing Portle or Palm Tips, it is important to keep the setter
perpendicular to the tree. Do not twist or move the setter side to side, as this may bend or break the injection tip. |
| |
Step 3: Release the setter from the injection tip. |
| |
Pull back on the QC coupler, remove the setter, and leave the injection tip in the tree. Continue inserting tips around the tree, following the spacing and number of injection sites information on the chemical label.
|
| |
Step 4: After all injection tips are set in the tree, attach the Direct-Inject unit front QC coupler to one of the tips. |
| |
While pulling back on the QC coupler, slide the unit over the tip, then release the QC coupler to lock the tip to the injection unit.
|
| |
Step 5: Squeeze both handles of the injector |
| |
at the same time using a smooth, firm motion. This places a pre-measured dose of chemical into the tree. Apply equal pressure on both handles—unequal pressure may bend or break the tip. Follow chemical label instructions to determine correct dosage.
|
| |
Step 6: After completing the injection, remove the injection unit from the tip |
| |
Leave the tip in the tree. Do not pull the tip out of the tree while it is
attached to the injection unit, as this may cause unwarranted damage to the
injection unit or injection tip.
|
| |
The ArborSystems Direct-Inject QC unit is preset to release
a 1 ml dose of chemical with each full stroke of the handles.
If you desire to inject a .5 ml dose of chemical, move the dose adjustment ring (see parts illustration #25) to the .5 ml dose adjustment groove (see #52). This will limit the handle stroke so the unit will release a .5 ml dose of chemical.
Avoiding chemical waste. Any time you remove a chemical pack (after making injections), there is approximately 2.5 ml of chemical remaining in the
injection unit. To not waste this chemical, remove the chemical pack before making your final injections. You will be able to make two additional 1 ml
injections (or four or five .5 ml injections) with the chemical remaining in the
injection unit.
| |
| |
Step 7: Remove the injection tips. |
| |
Reattach the setter to the tip and remove the
tip by pulling firmly on the slide with a straight rearward motion. Hold the setter
perpendicular to the tree to avoid bending the tips.

Successfully injecting conifers or palms
Injecting conifers Each Portle Tip has a check valve in the hub which keeps
chemical from coming out of the tip after the injection unit is removed from the tip. Individual trees absorb chemical at different rates. You may need to leave the Portle Tips in some trees longer than others, depending upon how fast the tree is absorbing the chemical.
To test if the chemical has been fully absorbed, slightly depress the check valve in a tip hub. If no chemical comes out, the chemical has been absorbed by the tree and tips can be removed. If chemical comes out of the tip, leave all the Portle Tips in the tree for a few more minutes until the chemical is fully absorbed
If you have injected more than 2 ml of chemical in a single injection site, some chemical may follow the tip out of the tree as you withdraw it, regardless of how long the tip has been in the tree. Withdrawing the tip slowly will minimize chemical loss.
Injecting palms Due to the absorbent nature of palms, check valves are not
required. Palm Tips can be removed immediately after making all injections.
