Fitting a new starter cord
6.
WARNING Spring tension
The starter spring may cause personal injury by
striking the operator or other persons.
► Wear impact resistant eye protection with side
protection and gloves.
Place the knot on the starter spring in the recess
on the inside of the pulley and wind in the starter
spring (anti-clockwise).
7. If the starter spring must be rewound, place the
spring-hook in the pulley groove and wind on the
spring anti-clockwise. If the spring must be
replaced, position the spring-hook above the
groove in the starter pulley. Leave the safety ring
in place, press down the spring into the starter
pulley.
8. Wind up the starter cord onto the pulley leaving
5 cm (2 in.) of slack. Locate the end of the spring
in the bushing groove, press the starter pulley
onto the bushing. Replace the lock ring.
Pre-load the starting spring
9. Place the notch in the pulley edge in line with the
starter cord guide and place the starter cord in
the notch.
10. Fit the lock ring.
11. Rotate the pulley 1 turn anti-clockwise.
12. Release the starter cord slowly.
13. Pull on the starting handle, check the function.
14. Pull out the starter cable, at the same time grip
the starter disc and check that if it can be turned
anticlockwise another 1/2 turn. If not, the spring
has been over-tightened and is touching the
bottom, the starter cable must therefore be
loosened a turn.
15. Fit the starting mechanism.
16. Check the function.
