TROUBLE SHOOTING
With considerate use, your Clarke HUNTER Air Compressor should provide you
with long and trouble free service. Routine checks should be made on both the
electrical supply as well as on all the compressed air lines and connections. If
any fault appears, the reason for which is not immediately obvious, we
recommend that you contact your local Clarke dealer.
CAUTION Do not attempt any repair or adjustment if you are uncertain as
to how it should be done. If you have any queries, contact your local
Clarke Dealer.
