OPERATING P RESSURE
Useonlyenough airpressure toperform theop-
eration. Airpressure in
excess of that which is re-
quired will make the operation inefficient and may
cause premature wear or damage to the tool.
Determine minimum air pressure required by
driving some test fasteners into the workpiece.
Set air pressure so that test fasteners are driven
down flush with the work surface. Fasteners driv-
en too deep may damage workpiece.

COLD WEATHER OPERATION
CAUTION: Do not store in cold environment. Frost
or ice could form inside tool affecting operation and
damaging
tool. Use a cold temperature lubricant,
such as ethylene glycol, when operating tool in freez-
ing temperatures.
LUBRICATION
Lubricate tool daily with quality air tool oil. If no air
line lubricator is used, place five or six drops of oil
into open end of tool male coupling every day.
MAGAZINE
Keep magazine and nose of tool clean and free
of any dirt, lint or abrasive particles.
SAFETY MECHANISM CHECK
Inspect contact trip safety mechanism daily for proper
operation.
With the red trigger switch in the rapid-fire mode,
perform the following procedures to test safety mech-
anism:
Leave trigger untouched while pushing contact
trip into workpiece. Tool must not fire.
Pull Trigger while contact trip is clear of work and
pointed away from operator and others. Tool
must not fire.
Depress and hold trigger. Push contact trip
against work where fastener as needed. The
tool should drive only one fastener each time the
contact trip is pushed against workpiece.
If the contact
trip mechanism
does not operate
properly,
immediately
discontinue
tool operation,
and take the tool to a qualified
service
dealer
for possible
repair. Reference the Parts List in this
manual for correct replacement parts.
