Automatic Air Tool
PROBLEM OBSERVATION CORRECTION
9) Tool doesn’t cut
off clamp.
- Cut-off cylinder stalls and does not
cut off clamp tail.
- Clamp tail bends and allows tool to
force buckle past cutter blade edge.
- Check for loose or broken cutter blade.
Tighten screws if loose. Replace cutter
blade if broken.
- Reset clamp hold pressure to recommended
pressure.
- If air line supply pressure is below 100 PSI,
stop operation and correct or allow pressure
to rise above 100 PSI.
- Check cut-off cylinder air cushion valve (fig.
14). It might be screwed in too deep.
- Cut-off cylinder piston seals leak. Loosen
nut off of tube Q. If air is still escaping
remove cylinder and replace seals.
- Cut-off cylinder piston rod may be binding.
Shut off air supply and remove tubes B and
Q and operate piston rod by hand to see if it
moves freely. If not, check back-up roller for
.010” clearance or remove cylinder.
- Lubricate between shear hook and cut-off
cam.
10) Tool never
reaches the
selected pull
pressure. Tool
operation may
be erratic in this
portion of the
cycle.
- Pressure observed increases, then
drops rapidly and jumps back up to a
higher pressure.
- Tool cycles to start the clamp holding
cycle before selected pressure is
observed on gauge.
- Increase the clamp pull cycle time to allow
the tool to regulate to the selected pressure.
- Air line pressure may be lower than the
selected pressure. Check and correct.
- Check the system for an air leak.
11) Tool takes
excessive time
for clamp pull-
up.
- Tool pulls the clamp and reaches the
selected holding pressure, then the
operator waits before the tool
operates to the holding and cut-off
cycle.
- Decrease the clamp pull cycle time (fig. 4).
12) Tool does not
tighten clamps
- Selection of higher clamp pull
pressure does not result in tighter
clamps. Excessive amount of air is
exhausting from the quick-exhaust
valve.
- Check for air system leak. Tighten or
replace defective items.
- Pull cylinder seal may be leaking. Operate
tool to stall the cylinder. Remove tube N and
if air is escaping, disassemble pull cylinder
and repair.
- Check to see if gripper level pin is dragging
on the base. Reposition and retighten the
set screw that retains the pin (fig 6).
