Safety and Cautions 

This equipment is to be used by trained firefighting personnel only.  Failure to 
obtain proper training  may result  in severe injury or death. 

Do not exceed maximum operating pressure.  Exceeding the maximum rated 
pressure for this appliance may cause malfunction, or failure resulting in severe 
injury or death. 

Failure of fittings and hoses can result in injury.  Use caution not to exceed hose 
pressures as stated in NFPA 1961 for the type of hose being  used. 

Make sure all connections are secure and complete.  Failure to ensure proper 
connection may result in leaks or cause the devices to become disconnected 
under pressure resulting in injury or death. 

Open and close all valves slowly.  Failure to operate valves slowly may cause 
water hammer, which may result in damage or failure of hose, coupling devices, 
and appliances leading to injury or death. 

Do not use if damaged.  Damage to product may cause malfunction or failure.  
Remove from service until unit can be repaired. 

Check for damage or worn coupling connections.  Damaged or worn connections 
may become disconnected under pressure.  Remove from service to be repaired 
by an AWG certified repair facility. 

For use with fresh or salt water, with or without firefighting foam. 

Altering of this device may reduce its operating effectiveness, or safety.  Do not 
alter or change in any way from its intended design.
