WARNINGS
• Always read tool manual before operating.
• Always wear safety glasses while operating or
while in the vicinity of a tool in operation.
• For testing, always cycle tool away from work
to insure proper ring closure. For safety
reasons, an improperly functioning tool must
not be used. When operating tool, never point
or actuate tool other than into work.
• Operate tool in an unobstructed work area.
• Disconnect air supply prior to maintenance
and/or repair of tool.
• Use clean dry air to maximize efficiency. Do
Not Exceed 100 P.S.I. (7.0 kg/cm sq.)
• Do not use bottled gases such as oxygen,
hydrogen, carbon dioxide, acetylene, etc.
• Tools shall be operated with a fitting or hose
coupling on or near the tool in such a manner
that all compressed air in the tool is discharged
at the time the fitting or hose coupling is
disconnected.

SAFETY INSTRUCTIONS
WARNING:
The employer and/or user must ensure
that proper eye protection is worn. Eye
protection equipment must conform to
the requirements of the American
National Standard Institute, ANSI Z87.1-1989 and
provide frontal and side protection. Eye protection
should be worn by the operator and others in the work
area when loading, operating, or servicing this tool.
Eye protection is required to guard against possible
flying particles and/or debris, which could cause
severe eye injury.
NOTE: Non-side shielded prescription glasses and
faceshields alone do not provide adequate protection.
OPERATION
Always handle tool with care:
• Never engage in horseplay.
• Never pull the trigger unless nose of tool is
directed toward the work.
• Keep others at a safe distance from the tool while
the tool is in operation as actuation occurs,
possibly causing injury. Keep hands and body
away from the jaw mechanism of the tool.
LOADING TOOL
When loading tool:
• Never place a hand or any part of body in jaw
mechanism area of tool.
• Never point tool at anyone.
• Never actuate tool when loading, accidental injury
may occur.
AIR CONSUMPTION
SC7 Series Tools require 1.6 cubic feet per minute
(.045 cubic meters per minute) of free air to operate at
a rate of 100 fasteners per minute, at 100 P.S.I. (7.0
kg/cm sq.).

to damage the o-ring during installation.) Do not overtighten front end assembly onto the housing.
20. Install (2) socket head cap screws (#2), locking front end
assembly into place. Do not over tighten as damage
could occur to front end assembly.
21. Cycle tool to ensure everything operates freely.
22. Cycle tool with rings in magazine. If tool is picking up
next ring or breaking next ring away from the strip,
disconnect air from tool.
23. Push slide back toward the housing and remove slide.
24. Install wavy washer onto the post of the slide.
25. Re-install slide in tool.
26. Test tool again for picking up next ring. If picking up
next ring, repeat steps 24 through 27.
27. Make sure tool is disconnected from air supply. Push
slide toward teeth area. Install socket head cap screw
(#25) into carriage. This keeps the slide from coming
out during use. If the slide is not pushed forward during
socket head cap screw installation, you will break the
carriage.
FILTER AND REGULATOR
1. 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.
2. The regulator should be set between 70 and 90 psi. (4.8
to 6.2 bar). Never operate this tool beyond 100 psi. (6.9
bar).

LUBRICATION
1. The “TR” series D-Ring 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.
TIPS ON EXTENDING TOOL LIFE
The serviceable life of the “TR” series tools can be extended
greatly by using the following guidelines:
1. Always use Stanley Fastening brand fasteners. Never
replace worn or broken parts with anything other than
genuine Stanley Fastening parts. Generic fasteners
may shorten the life of your D-Ring 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
noted above.
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 is a primary reason for parts
replacement.
5. 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.
CARRIAGE ASSEMBLY ROTATION
INSTRUCTIONS
The carriage is normally shipped in position #1, magazine
pointing downward, parallel to the handle.
To rotate the carriage to new position, loosen (2) socket head
cap screws (#2). Grasp the handle firmly in one hand, and
the carriage (#32) in the other hand.
With steady force, rotate the two sections. This will enable
you to put the front carriage assembly into any position you
need. Tighten the (2) socket head cap screws (#2).
DO NOT use excessive force when tightening any of the
screws. Screws should be snug but not over-torqued.
HELPFUL HINTS FOR FIELD SERVICE TOOL JAMS
The most common reason for jamming problems in the TR
tool is worn parts. The two most common replaced parts are
the jaws and the pusher assembly.
If tool begins to close ring poorly or spit rings, check for
worn parts.
RING DOES NOT CLOSE COMPLETELY
1. Check air pressure. Line pressure at the tool should be
between 70 and 90 psi (4.8 - 6.2 bar) for most
applications. The tool should never be operated at
pressures exceeding 100 psi (6.90 bar).
2. A 3/8” (9.5 mm) or larger air line should be used with
the “TR” Series Tools. Air lines in excess of 100’ (30.5
meters) in length can cause air volume deficiencies at
the tool which will prevent normal operation.
3. Check for foreign debris in the jaw area. This is
especially true in the area between the jaws and the
carriage.
4. The jaws may be worn from extended use. Check the
ring groove of the jaws. If the grooves are worn
excessively or have a chip out of them, replacing the
jaw(s) is recommended.
5. The arm links or pivot pins may be worn excessively,
replacing the part(s) is recommended.
6. When the tool is used in corrosive applications, light oil
should be applied on a regular basis to the carriage,
jaws, linkages and pins. Unlubricated and/or corroded
jaw linkages may cause the tool to function poorly.
FEEDING PROBLEMS
1. If rings do not feed smoothly through the magazine,
check pusher spring for proper tension. If the magazine
is covered with dirt from field use, clean the magazine
and apply a light coating of oil.
2. When rings feed properly through the magazine but do
not feed into the jaws without spitting out of the tool, or
if the rings sit in the jaw grooves on an angle, check
jaws to insure freedom of movement.
3. NEVER USE LOOSE RINGS IN THE TR201 /
TR203 TOOL.
NOTE:
Tool model number TR201 uses a short magazine/pusher
combination, part numbers TR417051F and TR105A027F,
measuring 6 inches long and capable of holding up to 50
rings.
Tool model number TR203 uses a long magazine/pusher
combination, part numbers TR419051F and TR107A027F,
measuring 11.25 inches long and capable of holding up to
100 rings.
