Installing The Interlock Throttle Grip
■
To avoid serious injury, grip the outer tube securely with one hand and cut
away from that hand when slitting the rubber throttle grip.
WARNING!
1. Place the T230 or PB230 outer tube assembly on a clean, flat surface.
2. Loosen the three screws that hold the throttle trigger assembly to the outer
tube.
3. Slide the trigger assembly down the tube, several inches away from the rubber
grip. Rotate the trigger assembly so it is flat against the work surface.
4. With a utility knife or similar tool, slit the rubber grip lengthwise to release it
from the tube. Use gentle pressure to avoid scarring the outer tube. See Figure
8.
5. Remove the grip and slide the throttle lever from the tube. Discard these parts.
6. Clean surface of tube in grip area.
7. Make a mark on the tube, 2 inches from the upper end. Slide the heat shrink col-
lar onto tube and align its upper end with the mark on the tube. See Figure 9.
8. Using a heat gun or hair dryer, apply heat to the collar until it shrinks and forms
a snug fit around the tube.
9. Slide the new interlock throttle grip assembly onto the tube, and position it over
the collar. Make sure the switch is facing up, and that the throttle cable and
switch wires are positioned toward the powerhead. Using a Phillips screwdriver,
tighten the grip's four clamp screws.
■
Failure to replace the standard throttle grip with the provided interlock throttle grip could
permit unintentional acceleration, which could cause serious injuries or death.

Powerhead Reinstallation
1. Place the powerhead on a clean, flat surface in an upright position.
2. Slide the outer tube into the tube clamp until the outer tube bottoms. It should
go in about 1-1/2 in. (38 mm). If the outer tube stops before bottoming, rotate
it until you feel the inner mainshaft (driveshaft) splines engage the powerhead.
Then push the outer tube all the way in. See Figure 11
Push the outer tube until it bottoms in the
clamp, rotating if necessary.
CAUTION!
Do not remove the D-shaped shim washer! The shim washer prevents damage
from overtightening the tube clamp screw.
CAUTION!
Do not force the lower tube into the powerhead! Excessive force can damage
the components.
