DESCRIPTION
This section provides the vehicle operator with step
by step operating procedures for the installed
MSC/MST system. The information is separated into
before operations, operations, and after operations. A
pocket size checklist of all listed procedures is also
provided in the Appendix for use in the vehicle cab.
BEFORE OPERATIONS
These procedures are used to perform a walk-around
inspection of the MEGA water tanker system before
use or the beginning of a shift. This inspection is in
addition to and does not replace the vehicle
manufacturer’s inspection requirements.
1. Chocks – As Required
2. Vehicle Parking Brake – ON
3. Cab Control Switches – SET OFF
4. Bumper Spray Heads – SECURED & SET
5. Vehicle Hydraulic Tank – SERVICED
6. Gooseneck Lines & Hoses – CHECKED & SECURED
7. Solenoid Control Box – CHECKED AND SECURED
8. Water Cannon – CHECKED & SECURED
a. Nozzle – Check for security and kinking of
foam concentrate supply line.
9. (If Equipped) Foam Concentrate Level –
CHECKED. At least 1” from the top of the foam
tank.
Ensure PPE fall arrest harness is worn, adjusted
properly and attached to an anchor point. Failure
to use PPE properly may result in personnel injury
or death.
10. Tank Drain Petcocks – CLOSED
11. Spray Heads – SECURED & SET
12. Water Pump Assembly – CHECKED
a. Water Pump – Check to ensure volute case
drain valve is closed.
b. Water pump and drive motor for evidence of
overheating.
13. Hose Reel – CHECKED
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, water cannon, 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
Engaging/disengaging the water pump above
LOW IDLE may result in water pump component
damage and reduced service life.
