MAINTENANCE
STARTER HOUSING ASSEMBLY
It is common for concrete slurry to get inside the starter housing
assembly during cutting. This can cause the starter pawls to stick
and not engage when the rope is pulled.
•
After each usage, thoroughly flush the starter housing assembly
with water.
•
Oil the recoil spring by spraying lightweight oil into the port
(Figure 3).
•
Oil the starter pawls by spraying lightweight oil into the starter
housing through the vents.
•
Check the starter rope for fraying, replace as necessary.
Starter Rope Replacement
•
Remove the 4 screws that attach the starter assembly to the
crankcase. Then remove the pulley dust cover.
•
Pull the cord out approximately 8” and lift the cord up into the notch
in the pulley (Figure 4). Relax the recoil spring by placing thumb on
pulley and gently allow the pulley to unwind entirely. Undo the screw
in the center of the pulley and remove the pulley.
•
Thread the new cord through the starter cover and fasten it to the
pulley. Wind approximately 4 turns of the starter cord on to the pulley.
Assemble the starter pulley against the recoil spring so the end of the
spring engages into the backside of the pulley. Install the retaining
screw in the center of the pulley.
Tensioning the Recoil Spring
•
Lift the starter cord up into the notch on the starter pulley (Figure 5) and
wind the pulley clockwise 7 full turns. Remove the cord from the pulley
notch while pinching the pulley. Release the pulley slowly allowing it to
wind the rope counterclockwise onto the pulley.
•
When completed, the starter handle should be pulled back in the starter
housing under it’s own tension.
•
To check that the starter pulley was assembled correctly, pull the cord
completely out of the housing, grip the pulley and turn clockwise
another ½ turn. If the pulley turns another ½ turn it is correctly
assembled.
