Powerhead Installation - Shindaiwa AH230 Owner's Manual

Powerhead Installation

1. Place the powerhead on a clean, flat
surface, spark plug facing up.
CAUTION!
Do not remove the D-shaped shim
washer! The D-shaped shim washer
prevents damage from overtightening
the tube clamp screw.
2. Use the 4mm hex wrench to loosen
the tube clamp screw. Verify that the
D-shaped shim washer is positioned as
shown below.

3. Remove the protective cap from the end
of the outer tube.
4. Add some moly-type EP grease to
splines at the end of the main shaft.
CAUTION!
Do not force the shaft tube into the
powerhead! Excessive force can
damage the shaft tube and mainshaft.
5. Slide the outer tube into the tube clamp
until the tube bottoms. If installation
is difficult, rotate the outer tube or
main shaft slightly until you feel the
mainshaft splines engage with the
powerhead. Outer tube needs to be
inserted so that end of grip hits joint
cap.
6. Position the outer tube so that the
ignition switch is facing up and the
throttle lever is facing down.
7. Tighten the clamp screw firmly.

ground lead is located on the rearward
side of the notch. Then, connect the
male fitting of the black ignition wire
into the female fitting of the red wire
attached to the engine.
