Product Usage Instructions

Full/Part Circle Operation
- All 8005 rotors are factory preset to part-circle at approximately 180 degrees.
Full-Circle Operation
- To set the rotor to full-circle operation:
- Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor.
- Turn the screwdriver clockwise so the blade is aimed toward the full-circle icon.
Part-Circle Operation
- To set the rotor to part-circle operation:
- Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor.
- Turn the screwdriver counterclockwise so the blade is aimed toward the part-circle icon.
Arc Adjustment
- Use the following instructions to adjust the arc settings:
- Method #1
- Adjust both arc edges of the rotor larger than desired.
- To adjust the left arc edge, trip the rotor so that it is rotating counterclockwise.
- Grip the nozzle housing to halt the rotation at the desired trip point.
- With the rotor aimed at the desired trip point, slowly turn the left adjustment screw in the clockwise direction until the torque of the nozzle turret is eliminated. This is a very subtle feel. The click sound of the trip may also be heard.
- Verify trip point during normal operation.
- Repeat the procedure for the right-side trip. The rotor must be tripped to rotate clockwise and the right edge adjustment screw should be turned counterclockwise to reduce the arc until it trips.
- Method #2
- Determine where the edges of the arc are by rotating the nozzle turret by hand and listening for the click sound or observing the trip during the operation of the rotor.
- Use the arc adjustment screws to increase or decrease the arc until the trip is at the desired location.
Nozzle Installation
- Step 1
- Insert the Pull-up Tool into the socket at the top of the rotor and twist 90 degrees. Pull the riser up to gain access to the nozzle opening and use the hold-up tool to support the riser in this extended position.
- Step 2
- Loosen the nozzle retention screw until it no longer obstructs the nozzle opening in the nozzle housing.
- Using both thumbs, press the colour-coded nozzle firmly into the opening until it is flush with the nozzle turret.
- Tighten the nozzle retention screw. The screw threads must engage the front surface of the nozzle to ensure proper seating of the nozzle.
- Step 3
- To remove the nozzle:
- Loosen the nozzle retention screw.
- Insert a flat-bladed screwdriver into the Side PryTM feature on the lower right edge of the nozzle to pry it loose.
FAQ
- Q: How can I adjust the rotor to full-circle operation?
- A: Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor and turn it clockwise towards the full-circle icon.
- Q: How can I adjust the rotor to part-circle operation?
- A: Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor and turn it counterclockwise toward the part-circle icon.
- Q: How can I adjust the arc settings of the rotor?
- A: There are two methods to adjust the arc settings. Method #1 involves adjusting both arc edges by tripping the rotor and turning the adjustment screws. Method #2 involves rotating the nozzle turret by hand and using the arc adjustment screws to set the desired location of the trip.
- Q: How do I install a nozzle on the rotor?
- A: Insert the Pull-up Tool into the socket, twist 90 degrees, and pull up the riser. Loosen the nozzle retention screw, press the nozzle firmly into the opening, and tighten the retention screw.
- Q: How do I remove the nozzle from the rotor?
- A: Loosen the nozzle retention screw and use a flat-bladed screwdriver to pry the nozzle loose using the Side PryTM feature on the lower right edge of the nozzle.

MANUAL

Circle Operation

Full/Part Circle Operation

(Refer to Figure 1 on the fold-out page) All 8005 rotors are factory preset to part-circle at approximately 180 degrees.

Full-Circle Operation

Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor. Turn the screwdriver clockwise so the blade is aimed toward the full-circle icon.

Part-Circle Operation

Insert a flat-blade screwdriver into the centre adjustment slot on the top of the rotor. Turn the screwdriver counterclockwise so the blade is aimed toward the part-circle icon. Use the following instructions to adjust the arc settings.

Arc Adjustment

Important facts:

The rotor may be adjusted to any arc between 50°–330° and full circle.
Both the right and left edges of the arc can be independently adjusted.
One full 360-degree turn of the arc adjustment screw will change the arc edge by approximately 120 degrees. Three full turns of the arc adjustment screw will rotate the trip edge completely around to the starting point. This is significantly different than most other rotors.
The edges of the arc cannot be felt when rotating the nozzle turret by hand. There is a light-click sound at the arc edge.
If the nozzle turret is rotated past the trip point, another click may be heard. This is the Memory Arc® function activating. No damage has occurred to the rotor. The rotor will click once again as it is turned back into the area between the arc edges.
The nozzle turret can be rotated by hand at any time in either direction with no damage to the rotor. The nozzle housing may be rapidly advanced by hand to speed up the arc setting process.
The arc of the rotor cannot be set to less than 50 degrees. If the 50-degree minimum is reached during adjustment, a hard stop will be felt on the adjustment screw. To continue moving the arc edge, move the other edge in the same direction first.
Then return and continue moving the first edge. If the adjustment screw is forced beyond the fixed stop, it will ratchet and click loudly a few times before damage occurs.

Setting the arc – Method #1:

Adjust both arc edges of the rotor larger than desired.
To adjust the left arc edge, trip the rotor so that it is rotating counterclockwise.
Grip the nozzle housing to halt the rotation at the desired trip point.
With the rotor aimed at the desired trip point, slowly turn the left adjustment screw in the clockwise direction until the torque of the nozzle turret is eliminated. This is a very subtle feel. The click sound of the trip may also be heard.
Verify trip point during normal operation.
Repeat the procedure for the right-side trip. The rotor must be tripped to rotate clockwise and the right edge adjustment screw should be turned counterclockwise to reduce the arc until it trips.

Setting the arc – Method #2:

Determine where the edges of the arc are by rotating the nozzle turret by hand and listening for the click sound or observing the trip during operation of the rotor.
Use the arc adjustment screws to increase or decrease the arc until the trip is at the desired location.

Nozzle Installation (Refer to Figure 2 on the fold-out page)

Insert the Pull-up Tool into the socket in the top of the rotor and twist 90 degrees. Pull the riser up to gain access to the nozzle opening and use the hold-up tool to support the riser in this extended position.
Loosen the nozzle retention screw until it no longer obstructs the nozzle opening in the nozzle housing.
Using both thumbs, press the colour-coded nozzle firmly into the opening until it is flush with the nozzle turret.
Tighten the nozzle retention screw. The screw threads must engage the front surface of the nozzle to ensure proper seating of the nozzle.
To remove the nozzle, loosen the nozzle retention screw and insert a flat-bladed screwdriver into the Side Pry™ feature on the lower right edge of the nozzle to pry it loose.
