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 Z87.1-1979 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 actuate pliers unless nose of tool is directed toward the work. 

 

Operate tool in an unobstructed work area. 

 

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.

SC50HP TROUBLESHOOTING GUIDE 

1.

 

The operator of the tool should understand that the success of operating this tool depends on the method (or technique) that the 
handles are operated.  The single most important issue will be in the outward movement of the handles during the ring loading 
cycle.  The handles must be opened completely to the full open position. This will need to be done in a continuous motion to 
prevent the tool from jamming.  Failure to do this will cause the ring to feed short of the latch nose.  The ring must feed beyond 
the latch nose to allow the latch to position behind the ring and prevent the ring from deforming during closure. 

2.

 

Any outward movement of the handles must result in the full ring loading cycle.  Partial outward movement will push a ring 
only part way forward.  When the handles are returned to the start position and then opened again the ring being fed on the 
second cycle will jam into the previously incompletely cycled ring.  This ring jamming will cause the tool to jam and lock the 
handles.  If the handles become locked the operator will need to remove the jammed rings from between the jaws.  This can be 
accomplished in the following ways: 

 

Most of the time this can be accomplished by using a screwdriver or other probing device to free the jammed ring(s). 

 

If  using the probe doesn’t remove the rings, than the following will be necessary.  Remove all rings from the magazine.  
Place the ring pusher in the parked position.  This is a point at the rear of the spring spool bracket.  Just hook the pusher in 
the slot near the bottom rear of the bracket.  Loosen both pivot bolt nuts 4 – 6 turns, this will allow more clearance between 
the jammed rings and the magazine.  This should now allow the removal of the jammed ring(s). 

 

In the event the above still doesn’t allow the removal of the jammed ring(s) then it will be necessary to remove the 
magazine completely.  When re-installing the pivot bolts or tightening the pivot bolt nuts, care must be taken not to over-
tighten the nuts. 

 
FEEDING PROBLEMS 

1.

 

If rings do not feed smoothly down 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 on the magazine but do not feed into the jaws without spitting out of the magazine side of the tool, or 
if the rings sit in the jaw grooves on an angle, check jaws to insure freedom of movement.  With the jaws void of rings, the 
vertical movement should be approximately .06” (1.5 mm).  The jaw bolt nuts should be snug, but 

never over-tightened

3.

 

After considerable use or several jams, the fingers on the pusher may show signs of spreading.  This may cause the pusher to 
“hang up” on the magazine, with little or no pressure behind the rings.  The last few rings in the strip will not feed into the jaw 
mechanism.  The pusher fingers can be squeezed back into proper position or the pusher should be replaced.  

NEVER USE 

LOOSE RINGS IN THE SC TOOL.
