Automatic Air Tool
ADJUSTMENT OF CYCLE TIME
The cycle time consists of two adjustable time elements. These can be adjusted as desired to: match
the operator’s skill, compensate for the difficulty of the assembly of the item being clamped, increase
or decrease the speed of the tool to allow the tool to tension the clamp, etc. A six second time for a
complete tool cycle is recommended as a reasonable time to make clamp assemblies, avoid operator
fatigue, and obtain a good production rate. The total time to apply a clamp will be increased by the
time to load the clamp on the item being clamped into the tool and removing the item and the spent
tail after clamping. It is not likely that the cycle time will need be adjusted frequently.
ADJUSTMENT OF CLAMP PULL TIME
This is the time needed to allow the pull cylinder to tighten the clamp and to build air pressure to the
pressure level selected. Pulling clamps with less than 40 psi does not require as much time to
tension the clamp so, if desired, the tool cycle time can be shortened. Conversely, if the tool is used
for clamps requiring pull pressure of 40 psi, or greater, the cycle time will need to be longer. To
adjust this time, remove the right side panel (4 screws) and locate the time delay valve (Fig. 4).
Locate the knurled adjustment knob (secured with a lock nut). Loosen the lock nut with a wrench and
turn the screw clockwise (right hand) to increase the cycle time, turn the screw counter-clockwise (left
hand) to decrease the cycle time. After an adjustment, it is recommended to cycle the tool a few
times to check the time to which the tool has been reset. When satisfied with the time, tighten the
lock nut to secure the adjustment knob and reassemble the side panel. A reasonable elapsed time
for this portion of the cycle is three seconds.
ADJUSTMENT OF CLAMP LOCKING AND CUT-OFF TIME
This is the time required to reduce the pressure in the pull cylinder to the clamp holding pressure and
to actuate the cut-off cylinder which locks the clamp and cuts off the clamp tail. For tools equipped
with the Band-It Jr. preformed clamp head, the operator must have time to roll the clamp up to
position for cut-off. Time required for roll up is dependent upon operator skill, familiarity with the tool,
weight and size of the item being clamped. To adjust this cycle time, remove the left side panel (four
screws) and locate the time control valve (Fig. 5). Locate the knurled adjustment knob (secured with
a lock nut). Loosen the lock nut with a wrench and turn the screw clockwise to increase the cycle
time, counter-clockwise to decrease the cycle time. Cycle the tool a few times to make certain the
cycle time is changed to that desired. Tighten the lock nut to secure the adjustment knob and
reassemble the side panel.
