OPERATING
PRESSURE
•
Use only enough
air pressure
to perform
the operation.
Air
pressure
in excess
of that which
is required
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
driven
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 freezing
temperatures.
Refer to Figure
12 (page 8).
LUBRICATION
Lubricate tool daily with quality air tool oil. If no air line lubri-
cator is used, place five or six drops of oil into air inlet cap
(Figure 12, Key No. 60).
MAGAZINE
AND
PISTON-RAM
•
Keep magazine
and nose of tool clean
and free of any dirt,
lint or abrasive
particles.
The tip of the ram (Fig. 12, No. 16) can become
dented
or
rounded
over time.
•
Square
off the tip of the ram with a clean, fine hand file to
extend
the life of the ram and tool. Fastener
firing will be
more consistent
if the ram tip is kept clean and square.
SAFETY
MECHANISM
CHECK
inspect
contact
trip safety mechanism
daily for proper
opera-
tion. Do not operate
tool if mechanism
is not operating
properly.
With the red push-button
switch
in the rapid-fire
mode,
per-
form the following
procedures
to test safety
mechanism:
•
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
is needed.
The tool should
drive only one
fastener
each time the contact
trip is pushed
against
workpiece.
If contact
trip
mechanism
does
not operate
properly,
repair
tool
immediately
through
Sears
Service
Center.
Replace
any damaged
or missing
parts.
Use the parts
list to
order
parts.
REBUILD
KITS
Rebuild
kits are available
as spare
parts,
(see page
9). Tools
should
be rebuilt
if tool fails to operate
properly
after extended
use. See troubleshooting
to determine
required
replacement
parts.
Disconnect
tool
from
air supply
before
attempting
repair
or adjustment.
NOTE:
When
replacing
O-rings
or cylinder,
lubricate
with
grease
before
assembly.
