DISASSEMBLING
! WARNING
Always wear safety glasses when servicing the recoil
starter.
1. Secure the recoil starter in a vise.
! WARNING
During the disassembly procedure, continuous down-
ward pressure must be exerted on the reel so it does
not accidentally disengage and cause injury.
2. Rotate the roller (B) counterclockwise until the notch
of the roller is near the rope guide in the case. Guide
the rope into the notch and slowly allow the roller to
retract until all recoil spring tension is released.
! WARNING
Care must be taken when allowing the recoil roller to
unwind. Make sure all spring tension is released
before continuing.
3. While exerting downward pressure on the friction
plate (C), remove the nut and washer (D).
4. Slowly release the plate and lift the plate with fric-
tion spring (E) free of the recoil roller; then remove
the friction spring from the plate.
5. Remove the pawl (F); then remove the return spring (G).
6. Carefully lift the roller free of the case making sure
the main spring (H) does not disengage from the
case.
Care must be taken when lifting the roller free of the
case.
7. Remove the main spring (H) from the case by lifting
the spring end up and out. Hold the remainder of the
spring with thumbs and alternately release each
thumb to allow the spring to gradually release from
the case.
 NOTE: Do not remove the main spring unless
replacement is necessary. It should be visually
inspected in place to save time.
8. Unwind the rope from the roller, untie the slip-knot,
and remove the rope.
