OPERATIONS
Use these procedures to safely operate the
standard and optional systems installed on the
MEGA water tanker.
Limit water pump operation to 2.5 minutes when
in a no-flow condition (not flowing water through
spray heads, dump bar, monitor, drain valve or
hose reel). Water pump operation in a no flow
condition will cause overheating of the water
pump and damage to the shaft bearings and seals.
Spray Head System
Operating more than 4 spray heads
simultaneously will greatly reduce the width and
flow of active spray heads.
1. Cab Control SYSTEM/POWER Switch – ON
2. INTERMITTENT TIMER – SET
a. TIMER ON/OFF Dials – SET
b. INTERMITTENT Switch – SET
3. PUMP Switch – ON

above LOW IDLE. Engaging/disengaging the
water pump above low idle will result in water
pump component damage and reduced
service life.
4. Individual Spray Heads – SELECTED
Once operations are complete:
5. PUMP Switch – OFF
Do not engage/disengage the water pump
above LOW IDLE. Engaging/disengaging the
water pump above low idle will result in water
pump component damage and reduced
service life.

GPS Auto Mode (DiSCS® 1.5)
When the chassis ignition switch is turned on, the
GPS module will attempt to make a satellite
connection. During this time, the AUTO light on
the cab control box will blink until a satellite
connection is established. If the AUTO light still
blinks when the cab control POWER switch is
turned ON, then the satellite connection has not
yet been established. Connection may take up to
10 minutes.
1. Cab Control POWER Switch – ON
2. PUMP Switch ON
Do not engage/disengage the water pump
above LOW IDLE. Engaging/disengaging the
water pump above low idle will result in water
pump component damage and reduced
service life.
