1.1.2 Pneumatic schematic
1.1.3 Functional description
A mechanical lock mechanism avoids simultaneous operation of tensioning and sealing lever.
• Pressing of the tensioning valve lever (a)
- The tensioning valve (1) is flowed through.
- The tension force control valve (2) is driven, the spring force is assisted and the valve is flown
through.
- The tensioning motor (3) starts.
- When reaching the preselected tension force the tension force control valve (2) is shut by the back
pressure of the tensioning motor.
- The motor stops.
- A return movement of the tension wheel is blocked by the needle free wheeling N3.4509.
- The tensioning valve lever (a) can be released.
• Activating the sealing valve lever (b)
- The welding valve (5) is flown through.
- The welding motor valve (6) is driven and releases the air flow to the welding motor (8).
- The welding motor (8) starts.
- At the same time the air is present at the turn off valve (9) and the welding time valve (7) is flown
through.
- When the preselected welding time (pressure) is reached the turn off valve (9) is driven.
- The turn off valve resets the welding motor valve (6) in combination with the spring pressure.
- The welding motor stops.
After the welding operation the welding lever (b) must be kept pressed in the welding position for 1-2 seconds in order to
let the welding seam cool down.
The outgoing air escapes in each case through the exhaust silencer (4).

PERIODIC MAINTENANCE AND CONTROL
1-8
1.3 PERIODIC MAINTENANCE AND CONTROL
Carry out 12- months cycles doing one shift work. Doing multiple shift work respectively more often.
1.3.1 Procedure
Before using check tool for following possible faults:
• Visual test of the tool for loose, lost or damaged parts
• Clean all dirty parts of the tool, especially strap abrasion in the tensioning or the welding unit by
using compressed air. (Never use any hard tools like a wire brush or a screw driver for cleaning)
• Condition of the tensioning wheel, the welding grippers and the tensioning grippers
Connect tool to the air supply and perform a test strapping.
Check the following:
• Tightness of the pneumatic system
• Strap guidance
• Strap feed and strap tensioning
• Tensioning force adjustment (see operation manual P355)
• Cutting of the upper strap
• Welding time adjustment (see operation manual P355)
• Welding pressure adjustment (see operation manual P355)
• Seal quality (see operation manual P355)
Proceed according to paragraph „Troubleshooting“ after a fault appears.
Attention!
Before maintenance always remove the tool from the compressed air supply.
For exchange of wearing parts see operation manual P355
Never use water or solvents for cleaning the tool’s surface.
