1-4 Disassembly of the Control Compartment
1) Before opening the Blocstop, the spring
tension must be reduced by pressing the
orange emergency stop button (Figure 106).
2) Inspect the handle {pos. 4, #41855} for
wear or damage. Ensure that there is no play
between the handle and the shaft {pos. 2,
#35147}. It must be tight without play. With
a 5mm pin punch, drive out the roll pin {pos.
74, #36786} as shown in Figure 107.
Replace any damaged parts.
3) Remove the (3) M6x60 casing screws
{pos. 75, #10166} and washers {pos. 79,
#36306} as shown in Figure 108.
4) Remove the casing cover {pos. 42, #18267}
to inspect the spring {pos. 72, #29446} and
cover for wear or damage. The spring should
be capable of compressing fully into the
brass cone without obstruction (Figure 109).
5) Inspect the centrifugal weights and the
release lever {pos. 3, #56235} for wear or
damage (Figure 110). Slight damage can be
filed, but you must inspect the air gap (0.4-
0.7mm) between the weights and release
lever upon completion (See Figure 111).
Replace any non-serviceable parts.
