Manual Override
In the event of power failure to the monitor, the motors may be actuated manually. To operate a
function manually, simply apply a ¾” ratcheting type wrench (either socket type or ratcheting box
end type) to the hex fitting on the motor shaft.
Warning:
Using the horizontal override nut when the power to the receiver is off or the horizontal motor is
disconnected will move stow position from its original programmed position. See section titled V.D
Travel Limits and Stow Position Programming to realign stow position even if stow feature is not
utilized.
Caution:
Do not use impact drivers to operate manual override nuts. Serious damage to motor gear heads will
result.
*Note:
The SM-1250E and SM-2000E nozzles have a unique ball screw drive that allows motor to
“free wheel” at the end of pattern travel in either the straight stream or wide fog positions. No slip
clutch or current limiting feature is used with these nozzle drives.

Storing the Monitor
These monitors have a user selectable stow position (see V.D for setting instructions). After the
water supply to the monitor has been turned off, simultaneously press the “Stow” and “Fog” buttons
on the primary panel mount RF transmitter (buttons must be held down for a minimum of 3 seconds).
The monitor will automatically rotate horizontally to the stow position previously programmed and
either lower or raise the discharge to its mechanical stop (depending on the position of switch A
position 1 on the receiver board). Prior to stowing the monitor the stow signal output provides a
ground signal. There are two settings for stow signal output.
Switch 4 position 1 (Signal mode)
Once the monitor starts to move to the stow position, the stow signal output will alternately supply
and remove the ground, at approximately a 1 second rate, while the monitor is moving to the stow
position. Once the monitor has completed the stow sequence the stow signal output will be an open
circuit - see warning at the end of this section.
Switch 4 position 2 (interlock mode)
Once the monitor starts to move to the stow position, the stow signal output will continue to supply a
ground while the monitor is moving to the stow position. The ground will be removed after the
monitor reaches the stow position and the stow signal output will be an open circuit. - see warning at
the end of this section.
Note: If the stow indicator does not turn off, see the V.D section to realign the stow position.
Any directional command (left, right, up, down, fog or straight stream) will cancel the “stow”
command, and the stow output signal will continue to provide a ground. To stow the monitor the
stow command must be reactivated.
