  1. FOUR INCH HOSE CLAMP The proper placement of the hose clamp

  2. AT LEAST 20 FEET BEHIND THE ENGINE. • The reason for this is to prevent the possibility of the clamp being driven under the engine as the hose is charged and to remove the clamp from the immediate work area behind the engine is less than 20 feet away, the clamp will have to be applied behind the next coupling 60 to 70 feet back. Although this seems a long way, in reality this placement adds only seconds to an evolution.

  3. 18 INCHES BEHIND THE COUPLING ON THE SUPPLY SIDE • The reason for placing the clamp 18 inches behind the coupling is to prevent uncontrolled sliding of the clamp along the hose. At times as the clamp is removed, the movement of water inside the hose moves the clamp along the outside of the hose at the same velocity as the water (FAST). This can damage the hose and couplings and certainly injure anyone struck by the clamp. By placing the clamp 18 inches behind the coupling, the clamp cannot gain enough momentum to cause damage or injury, yet allows the coupling to be disconnected if necessary.

  4. THE HOSE ON THE SUPPLY SIDE SHOULD BE STRAIGHT BACK TOWARDS THE WATER SOURCE NO BENDS OR TWISTS • The reason for keeping the hose straight from the clamp towards the supply source is the fact that any turn or twist in the hose straightens out as the line is charged. If the clamp is ahead of a bend or twist, it can be turned over as the hose is charged. This can cause the clamp to come undone or make it difficult to turn the handle (the entire clamp can be turned 90 degrees or more). See attached drawing.

  5. Applying the Hose Clamp to a Supply Line • Remove the clamp from the engine.

  6. Locate the first coupling that is at least 20 feet behind the engine. Open the clamp and apply it 18 inches behind the coupling on the water source side.

  7. Secure the clamp snugly with one foot on the latch side. Note: if you foot the clamp opposite the latch and the clamp releases prematurely you could be injured.

  8. Use both hands to rotate the clamp up until the clamp jaw is completely above the hose.

  9. Release the latch and slide the clamp out from under the hose. Return the clamp to the engine.
