OPERATION Feeding the strap around the package The strap is fed around the package in the direction as shown in the illustration. The end of the strap is held tightly with the left hand and pulled firmly towards the operator with the right hand.
Throttle valve On all tools provided with the throttle valve the air supply can be adjusted on the throttle screw A3H.1810. Sealing the strap Press the valve lever with the thumb of the right hand until the seal is done. Removing the tool from the tensioned and sealed strap.
SEAL CONTROL A regular control of the seal is necessary. The seal can be checked visually and the person controlling can easily judge the quality of the seal. When checking the seal the following illustrations must be compared. Correct seal A correct seal must be conform to the illustration.
10 SEAL ADJUSTMENT The sealing- and cutting depth of the sealing mechanism and the cutter can be adjusted with a screw driver by turning the adjusting screw A3H.1709. Sealing depth is excessive Turning the adjusting screw A3H.1709 clockwise reduces the sealing depth. A turn of 90° equals adjustment of 0.25 mm / .010".
11.4 Control of oil level According to the use of the tool the oil-level must N1.1111 be checked periodically and the inside of the cylinder must be cleaned at the same time. This Suspension Suspension bracket oil control is necessary because it prevents that due to oil losses over a certain period of time the sealing mechanism does not reach the necessary stroke.
12.2 Tensioning wheel The tensioning wheel should be exchanged if its teeth are dull and the wheel revolves without transporting the strap. Procedure: • Unscrew the screws N1.1113 and disassemble the end cover. • Disassemble the security ring N2.1108. • Disassemble the spacer ring A3H.1504 and the tensioning wheel A3H.1503.
12.4 Punch and die If it‘s impossible to make a correct seal although the adjustment of the adjusting screw is correct (see SEAL CONTROL) the base plate has to be disassembled and the wearing of the stamp tools has to be checked. If the cutting edges are damaged or blunted (Attention! The cutting edges are also slightly rounded off when they are new) the used parts have to be exchanged.
