Parts Required:
PAS or SRM-SB Power Head w/Shaft & Coupling.
1. Set Power Head/Shaft Assembly on a level surface.
2. Pull locator pin (A) out, and turn counter-clockwise 1/4 turn to
lock-out position.
3. Remove vinyl cap from attachment drive shaft.
CAUTION:
Thrown objects hazard. Install lower drive shaft so that gear hous-
ing clamping bolt (F) faces downward. Otherwise debris will be
thrown toward users.
4. Remove cardboard spacer, if necessary.
5. Carefully fit attachment drive shaft assembly into coupler (B) to
decal assembly line (C), making sure that the inner lower drive
shaft engages into the square upper drive shaft socket.
NOTE
Earlier model Power Heads may have shorter couplings. Short
couplings fit flush to decal point (E). New couplings are 4-3/4 in.
long, and fit flush to line (C).
6. Rotate locator pin (A) 1/4 turn clockwise to engage lower shaft
hole. Insure locator pin is fully engaged by twisting lower drive
shaft. Locator pin should snap flush in coupler. Full engagement
will prevent further shaft rotation.
7. Secure lower shaft assembly to coupler by tightening clamping
knob (D).
