9820K Nozzle Locking
A locking mechanism is supplied as part of the hook arrangement on each 9820K
(see
). This allows the unit to be locked, thus preventing the use of the
pumps.
A lock with a shackle clearance of at least 2-1/2 inches is required to lock the pump
(for example, Master No. 1LJ-D). To lock the nozzle in place, proceed as follows:
1
Insert the nozzle onto the hook assembly with the nozzle tip inside the boot.
2
Slide the rear bracket of the nozzle hook assembly upward until the holes near the bottom of
the nozzle are aligned.
3
Slide the open padlock through holes in the moveable and stationary portions of the hook
arrangement, thus capturing the nozzle in place.
Note: The four holes will not align until the moveable bracket has been slid upward.
4
Close the lock.
While the nozzle is locked in place, the nozzle cannot be removed from the nozzle hook and
the pump cannot be turned on.
