OPERATING INSTRUCTIONS (Conti nued)
OPERATING PRESSURE
Use only enough air pressure to perform the stapling
operation. Air pressure in excess of that which is re-
quired will make the stapling operation inefficient and
may cause premature wear or damage to the tool.
Determine minimum air pressure required by driving
some test staples into the workpiece. Set air pressure
so that test staple crowns are driven down flush with the
work surface. Staples driven too deep may damage
workpiece.
EXHAUST PORT
Refer to Figures 4 & 5.
Exhaust port can be positioned at the left, front or right
side of tool. Reposition deflector (Key No. 6) by carefully
removing four socket head bolts (Key No.4)and rotating
deflector to desired position.
Be sure notto misplacevalve spring (Key No. 7). Secure
four socket head bolts, making sure that valve spring
and deflector are properly positioned.

MAINTENANCE
Refer To Figure 5.
Lubricate tool daily with quality air tool oil. lf no air line
lubricator is used, pour five to six drops of oil into inlet
(Key No. 3) of stapler everyday.
Keep magazine and nose clean and free of any dirt, lint
or abrasive particles.
The tip of the ram (Key No. 17) 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
stapler. Staple firing will be more consistent if the ram
tip is kept clean and square.
lnspect contact trip safety mechanism daily for proper
operation.
Do not operate stapler if mechanism is not operating
properly.
Perform the following procedures to test safety mecha-
nism:
l.Leave trigger untouched while pushing contact trip
into workpiece. Stapler must not fire.
2.Pull stapler trigger while contact trip is clear of work
and pointed away from operator and others. Stapler
must not fire.
3.Depress and hold trigger. Push contact trip against
work where staple is needed. The stapler should drive
only one staple each time the contact trip is pushed
against workpiece.
lf contact trip mechanism does not operate properly,
repair stapler immediately through Seais Service Cen-
ter. Replace any damaged or missing parts. Use the
parts list to order parts.
TROUBLESHOOTING
Refer to Figure 5.
WARNING: DISCONNECT TOOL FROM AIR SUP-
PLY BEFORE ATTEMPTING REPAIR OR
ADJUSTMENT.
lf staple jams in nose of tool, open magazine and
remove staples. Loosen two socket head bolts (Key No.
59) and remove nose cover (Key No. 56). Remove
jammed staple, replace nose cover and secure bolts.
lf tool will not fire or loses power, the O-rings may need
cleaning and lubrication. Remove deflector (Key No. 6)
and carefully remove cap, cylinder valve, piston, and
cylinder (Key Nos.9, 13, 17 &19). Clean all O-rings and
O-ring grooves with clean, dry cloth. Be careful not to
damage O-rings.
Replace O-rings if worn, stretched or damaged. Coat
O-rings and grooves with air tool oil. Assemble in re-
verse order of disassembiy.
lf tool trigger valve leaks, check O-rings (Key Nos. 25 &
28).
If ram fires but does not return, check piston O-ring (Key
No. 16).
lf tool leaks from under cap, check cap O-ring (Key No.
11).
lf tool leaks out of back of cap when trigger is depressed
and will not fire, check O-rings on tube (Key Nos. 22 &
24).
lf tool will not fire and leaks out of deflector, check
cylinder valve O-ring (Key No. 12).
