tank and moisture filter daily. (Storage tank drains are
usually located on the bottom of the tank(s). The mois-
ture filter is generally located next to the regulator.)
3. Check the regulator(s) for the correct air pressure and
that all valves to the supply line are open.
4. Check the fittings and hoses for kinks, leaks, or block-
ages and ensure they are
operation.
5. If a tool known to be in working condition is available,
connect it in place of the malfunctioning tool and test
it to see if the problem disappears. If the problem con-
tinues, then the problem is probably not in the tool.
IMPORTANT NOTE: If servicing a tool is required, ALWAYS
disconnect the tool from the air supply and empty the
magazine before attempting to service the tool.
