CONTROLLED SPREADING (M917A1 WITH MCS AND M917A2 WITH MCS)
WARNING
DO NOT connect or disconnect MCS remote control when dump body is being
raised or lowered.
When connected, MCS remote control overrides cab control unit. When remote
control is disconnected, cab control activates. To avoid inadvertent opening or
closing of gates, ALWAYS check gate positions and position of toggle switches on
both cab and remote controls before plugging in or unplugging remote control.
Toggle switches should be in CLOSED position.
DO NOT spread or dump payload with dump truck facing a steep upgrade or a
steep side slope. Dump truck may tip over backward or sideways.
DO NOT stand or walk behind dump body when it is dumping or in raised position.
When using MCS remote control, always walk or stand to side of dump body.
Keep hands and feet away from gate openings at all times.
Operator inside the cab must be aware of the location of outside personnel at all
times.
Failure to comply may result in personnel injury, death, and/or damage to
equipment.
NOTE
Operation requires two personnel: driver and assistant driver.
1.
Follow instructions for preparing to dump, except for the following steps:
a.
DO NOT unlock tailgate.
b.
Adjust MCS gate openings.
2.
Ensure that toggle switches on MCS control unit inside cab are in CLOSED position (WP 0004).
3.
Remove MCS remote control (Figure 8, Item 4) from stowage. Ensure that toggle switches (Figure 8, Item 3)
are in CLOSED position. Plug remote control into receptacle (Figure 8, Item 5) at passenger's side or
driver's side of MCS tailgate (Figure 8, Item 1).
4.
Move toggle switches (Figure 8, Item 3) to OPEN position. Depending on desired spreading pattern, all
gates (Figure 8, Item 2) or selected gates may be opened.
5.
Raise dump body 2 to 3 ft (61 to 91 cm) and stop. Material should begin to spill out through gates
(Figure 8, Item 2).
6.
Have driver pull forward with transmission in first gear (TM 9-2320-363-10 or TM 9-2320-302-10). Maintain a
steady speed not to exceed 3 mph (5 kph). Have assistant driver check thickness of dumped material to
determine if gate openings need adjusting.
7.
If adjustment is needed, stop dump truck, lower dump body, close gates (Figure 8, Item 2), place
transmission in N (Neutral), and set parking brake. Adjust MCS gate openings.
8.
Maintain a steady speed until all material has been spread. Raise dump body periodically to keep material
flowing evenly through gates (Figure 8, Item 2).
