Once assembled, is any ongoing maintenance required?

Upon assembly, ensure that the cover of your shelter is well tensioned and reqularly check that this tension is maintained at all times. Good tension means you should find it difficult to squeeze your hand between frame and cover. 

Ensure that the choke ropes at the front and back remain tied off, and tight.  Make sure that the ratchet straps remain well tensioned and in place.  Do not remove any ratchet straps without replacing them,  or untie any choke ropes or wires  without ensuring they are resecured after.   Check periodically and replace where necessary.

A well tensioned cover will mean that it will not rub or wear on the frame of the shelter.  A loose and flapping cover will pull and place pressure on your frame, as well as creating points of wear and friction on the cover.

Check that your shelter continues to remain firmly fixed down to the surface you have assembled it on.  Ensure augers and stakes are always secure to prevent movement.  Make sure that your frame remains bolted firmly and cannot move. 

Bungee's will require replacement periodically so that they remain elastic and firm fitting.  Replacement bungees are available for purchase. 

Wash your shelter down occassionally with a soft brush and hose.  Do not waterblast or use any harsh or abrasive chemicals to clean.
