HOSES
Hoses should be checked regularly for signs of wear and tear or damage (e.g. abrasions,
bulges, distortion, etc.) and any hoses showing such signs should be replaced.
Also replace any hose which can no longer be adjusted not to touch the ground when the
nozzle is holstered correctly.
Most hoses are removed by undoing the brass swivel nut that secures them to their
respective delivery pipes. With High Arms it will be necessary to remove the cotter pin
and two cap screws in order to release the hose.

In some cases, for ease of access, it would be advisable to undo the cap screw holding the
bottom of a channel runner and swing it up out of the way.
