5-6 FUZE SETTING — CONTINUED

e. Procedure Number 5, M577 and M582 Series Fuzes — Continued

To set the M577 or M582 series fuze for mechanical time action, turn the M35 fuze setter (8)

the hairline. This action occurs near a 000 setting. Continue to turn M35 fuze setter counterclockwise

until desired time appears under the hairline. Maintain a very light turning force against the M35 fuze

setter while reading the setting. The A-F sequence is illustrated for settings of 8.7, 25.5, and 107.4.

To set a lower time on M577 or M582 series fuze already set, reseat M35 fuze setter (8) and turn

clockwise (numbers get smaller) to a setting at least one second lower than the required setting (for

example, at least 24.5 for 25.5). Reverse direction to counterclockwise (numbers get larger) and set

required time under the hairline.

To return M577 or M582 series fuze to the shipping and storage (safe) setting, turn the M35 fuze setter

(8) clockwise (numbers get smaller) until 000 is passed, and continue to turn until M35 fuze setter stops

M582 series fuze to the reusable fuze container. The M577 or M582 series fuze is considered

unserviceable after being out of the container for more than 30 days.

For special preparation of M577 series fuze, inspect the M577 fuze setting. The M577 series fuze will be
