OPERATION MANUAL / SPARE PARTS LIST PNEUMATIC STEEL STRAPPING TOOL MODEL A383.0001 13.6750.01 CE Declaration of conformity We declare that the machine A383 is in conformity with the following standard or standardised documents: 98/37/EEC FROMM Holding AG Hinterbergstrasse 26 CH - 6330 Cham 27.03 2001...
SAFETY INSTRUCTIONS Read these instructions carefully. Failure to follow these instructions can result in severe personal injury. Eye injury hazard Strap breakage hazard Failure to wear safety glasses with side shields can result in Improper operation of the tool, excessive tensioning, using strap severe eye injury or blindness.
WARRANTY CONDITIONS AND LIABILITY FROMM Holding AG warrants all its strapping tools and machine heads during a period of 24 months from the date of installation at the end-user's sight by the distributor, however, not later than 30 months from the date of shipment to the distributor of FROMM Holding AG.
TECNICAL DATA Dimensions without suspension bracket Length: 420 mm / 16.5" Width: 195 mm / 7.6" Height: 350 mm / 13.7" Weight: 23.1 kg / 50.82 lbs Sound information The A-weighted equivalent continuous sound level at the work place of the machine operator is typical 78 dB (A).
INSTALLATION Compressed air connection The compressed air should be connected to the tool preferably by a quick disconnector. It is very important to clean the compressed air with an air unit consisting of a separator for water and dirt, a pressure regulator with a manometer and a lubricator.
OPERATING CONTROLS Lever Motor valve lever Sealing valve lever Flapper valve lever OPERATION Feeding the strap around the package The strap is fed arround 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.
Tensioning the strap The motor valve lever is pressed down with the thumb of the right hand so that the catch locks. Let the tool tension until the motor stalls. If the tensioning cycle has to be interrupted (faulty strapping, applying of corner protection angles) press the red lever.
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 depth of the sealing mechanism and the cutter can be steplessly adjusted by turning the adjusting screw with a screw driver. Sealing depth is excessive Turn adjusting screw clockwise. A turn ° of 90 equals a stroke correction of 0.25 mm/.010".
11 MAINTENANCE Depending on the working conditions and the use of the tool the following maintenance has to be made periodically: 11.1 Air-unit • Checking the air pressure daily. • Checking the oil-level daily. • The water separator must be emptied before it is full (unless automatic). •...
11.3 Cleaning If impact of dirt and dust is considerable and if painted straps are used the feed wheel must be cleaned regularly. Normally it is sufficient to blow out this part by using an air gun. 11.4 Lubrication The gear is filled with MOLYKOTE BR 2 PLUS. Use the same type of grease after repairs. When being exchanged, all valve parts and other movable parts have to be greased with grease of type Mobilux EP2 or with any equivalent product.
12.2 Exchange of the feed wheel • Remove the left strap stop • Unscrew the three screws and remove the bearing cover. • Remove the front distance ring, the O-ring and the feed wheel from the feed wheel shaft. • Assembling in opposite order. Important! Take notice of the assembling position of the feed wheel.
12.4 Exchange of cutter • Remove base plate, guard plate with guide and right strap stop. • Using a hexagon socket spinner wrench to unscrew and remove cutter screw M6 x 12 across the appropriate boring in the sealing body. •...
14 Functional characteristics Idle position Because of the connection of the tool to the compressed air-net (connection P) compressed air flows through flapper valve 3 to the flapper cylinder 19 and rocker cylinder 17. As a result of this air-flow, the closing force of the spring of the flapper cylinder 19 is supported by compres- sed air on the one hand (flapper closed) and the feed-wheel is lowered to the gripper on the other hand.
As soon as the upper strap is sheared off, the sealing valve lever 25 can be released. Sealing valve 5 switches to deaeration, the compressed air in cylinder 20 starts to flow back and escapes through the pressure reduction valve 15 (back stroke area), sealing valve 5 and the lower part of the cylinder 20 into the athmosphere.
