Inspection and Maintenance
STEP 10� Check the operation of the brake linkage as
follows:
(a) Pull the latch knob on the hub of the manual
operating handle and slowly pivot the handle
forward from its Storage position toward
its Cranking position until the brake disc
can be rotated by hand. Be careful not to
get grease on the brake disc.
(b) Measure the distance the end of the brake
lever travels from the point of initial
brake release to the bottom of its stroke.
(This occurs when the handle locks into
the Cranking position). This dimension
should be ⅛-inch (3 mm) to ¼-inch (6 mm).
See Detail D in Figure 8 on page 17. If the
measurement is outside this range, contact
the nearest S&C Sales Ofce.
STEP 11� Finally, to check the functioning of the brake,
decouple the operator and then open and close
the operator electrically. After each operation,
check the position of the indicator on the appro-
priate travel-limit disc. It should stop between
indicator plate numbers 2 and 8. See the switch-
operator travel-limit adjustment instructions on
enclosure door. If the indicator on the travel-limit
disc stop is outside this range, contact the nearest
S&C Sales Ofce.
