BBC / BOS / BCS
When the control bar is released, the tip of the control
hook catches on the leaf spring causing it to rotate. This
releases the BBC cable lever, thereby causing the BBC
to declutch and apply the blade brake (Fig. 186).
Control Box Disassembly
Note: When servicing the BBC control box, be
careful not to disassemble the unit any further
than necessary as it will then become difficult
to trouble shoot. Instead, remove the right
housing half, then operate the control box
while watching for proper function of internal
components. See Step 5 below for more
information.

A
1.
Place a piece of duct tape over the heads of the
carriage bolts passing through the handle and the
BBC control box. This will prevent them from falling
out later during troubleshooting.
B
2.
Bend the locking tab securing the throttle control to
the control panel, then tap the throttle control out
using a rubber mallet.
3.
4.
Remove the 3 flanged head screws retaining the 2
control box halves.

Carefully remove the 2 flange nuts retaining the
control box to the handle and remove the right
control box half. Be careful not to dislodge any
internal components.
A. Contact point
B. Leaf spring
C. Flange nut
5.
Reinstall the flange nuts to help hold things together.
Determine if any of the components inside the
control box are malfunctioning.
CAUTION! Wear gloves and eye protection when
operating an open control box as the buckling
spring could fly out.
Note: The cable ends and end of the spring are not
retained once the right cover is removed. Be
sure to use one of the two methods below to
retain them.
The first and quickest method is to manually hold the
ends of the cable and the end of the buckling spring
while operating the control bar. However, with the
right case half removed, the leaf spring is no longer
in place and you will not be able to observe release
of the BBC cable lever.
