ASSEMBLY
Tools Required: None
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. 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 120 mm
(4-3/4 in.) long, and fit flush to line (C).
NOTE
Lower bearing housing and head assembly must be in line with the
engine.
4. 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.
5. Secure lower shaft assembly to coupler by tightening clamping
knob (D).
