INSTALLATION PROCEDURE / ADJUSTMENTS
Magazine
1. Before tightening jaw bolts (#35), insert approximately
.070” of shims.
2. Tighten bolts and check magazine shoe (#30) for proper fit.
3. When shimmed correctly, and with the feeder blade in the
forward position, the shoe should have approximately
.010”(.25mm) float up and down.
4. Cycle tool and check for proper ring closure. If feeder
blade hits rear of shoe, add another shim. Shims (#32) are
available in two thickness’ of .005”(.013mm) and
.010”(.25mm).
5. When the tool is completely re-assembled, check to insure
that magazine (#34) is parallel to housing (#48).
Throttle valve
Follow these steps after completing tool assembly in order to
minimize the time and effort required for optimum throttle valve
adjustment:
1. Using the valve stem (#43), slowly screw in the front valve
seat (#44) until it bottoms then back it out 1-1/2 turns.
2. Do the same with the rear valve seat (#54).
3. Attach an air line and fully depress the trigger. AIR
SHOULD LEAK OUT THE REAR VALVE SEAT. While
depressing the trigger, slowly turn in the rear valve seat
(#54) until the air stops leaking.
4. Release the trigger. AIR SHOULD LEAK OUT OF THE
HANDLE. Place a 3/16 wrench on the trigger valve stem
(#43) and turn the front valve seat (#44) in slowly until the
air stops leaking from the handle.
5. Gently depress the trigger. Air should flow evenly from the
rear exhaust to the handle exhaust.
6. The valve should now be adjusted - test the tool.
7. Tighten the front and rear valve seat locking set screws (#9)
and re-test the tool.
TOOL LEAKS AIR OR IS SLUGGISH
1. If tool is leaking air in the throttle area, see “Throttle Valve
Adjustment” section.
2. Should the tool leak air in both the triggered and rest
positions, a damaged piston o-ring may be the cause. Once
the piston o-ring has been replaced, lubricate with lithium
grease.
3. Put a few drops of light oil into the inlet fitting to lubricate
the piston o-ring if tool is running sluggish.
4. If the tool is operating too quickly for the operator, remove
button head cap screw (#56) and replace with set screw, jam
nut and shakeproof washer (part numbers SC25, SC15 and
SC28). The set screw can be used as an air flow control
device.
CONVERTING TO A LEFT HANDED TOOL
1. Remove (2) jaw bolts, nuts, washers, and latch spring (#35,
#20, #19 and #18).
2. Remove magazine assembly and pusher system.
3. Remove latch (#21) and move to other side.
4. Remove jaws, jaw bushings and spring washers (#22, #25,
#23 and #57) and place them back in the opposite way.
5. Place magazine assembly and pusher system onto other side
6. Replace latch spring and fasteners.
7. Remove (4) button head cap screws (#1).
8. Move pusher hook bracket (#2) to other side.
9. Replace fasteners.
LUBRICATION
1. The “SC” series Flex-C tools are designed for long, trouble-
free service with minimal air line lubrication. (If an in-line
lubricator is used, it should be set at the minimum rate of
flow.)
2. Excess oil in the tool will attract dirt, lint, and the adhesive
material used in collating the fasteners, preventing smooth
operation. When lubrication is used, always use a good
grade of 5W non-detergent oil with no additives.
3. When servicing or repairing tool use lithium grease on all
moving parts.
FILTER AND REGULATOR
The air line should always contain a filter and regulator unit
to
provide the tool with a constant flow of clean, dry air. If
moisture and contaminates are allowed to enter the tool, the
tool’s serviceable life will be decreased.
TIPS ON EXTENDING TOOL LIFE
The serviceable life of the “SC” series tools can be extended
greatly by using the following guidelines:
1. Always use Stanley Fastening Systems brand fasteners.
Never replace worn or broken parts with anything other
than genuine Stanley Fastening Systems parts. Generic
fasteners may shorten the life of your Flex-C tool and will
void the manufacturer’s warranty.
2. Keep your tool(s) clean and dry. Always use clean, dry air
and never exceed the recommended air pressure.
3. Use of this tool at minimum air pressure required for the
work at hand will greatly extend the life of the tool.
4. Exercise caution not to drop equipment. Tools dropping
onto the floor or ground are a primary reason for parts
replacement.
HELPFUL HINTS FOR FIELD SERVICE TOOL JAMS
1. The most common reason for jamming problems in the SC
tool is short cycling. Because of the tool’s valve unit, the
trigger must be pulled completely to the rear to ensure
positive functioning of the valve. If the tool is “short
cycled,” the feed mechanism will return forward
prematurely in an attempt to pick up a second ring. This
will most likely cause a jam.
2. If a jam occurs, pull pusher and rings back on magazine.
Point tool away from yourself and others, and cycle tool
slowly. This should force jammed ring(s) out of jaw
mechanism.
3. If procedure “2” does not clear the tool, disconnect air, lay
tool on a clean flat surface and remove top jaw bolt and nut,
and pull top jaw and bushing from tool. Jammed rings are
now exposed and may be removed from tool. Remove
build up of dirt, lint, and any other foreign debris and check
for worn or damaged parts. Re-assemble in reverse order.
4. Replace worn or damaged parts to keep tool operating
properly.
