5.9.2
Disassembly of the planetary gear
Dismantling
►
Disassemble the rocker lever and then the connecting
parts (chapter 5.6.1).
►
Disassemble the tensioning system (chapter 5.8.1 or
5.8.2).
► Remove the five cylinder screws # 184 from flange
# 32 and remove these from the base plate.
► Now the gear can be removed from the flange without
any problem.
Fitting
►
Carry out assembly in the reverse order.
►
The toothed ring # 19 must be very easy to turn, espe-
cially with tool BXT3-19. Lubricate the outside of the
toothed ring with light oil only.
►
Tighten cylinder screws # 184 with a torque of
3.0 Nm.
5.10 Blocking of the welding mechanism
ATTENTION
In exceptional cases, it may occur that the welding mechanism can no longer be returned to the initial
position. The rocker lever is jammed.
Never pull on the rocker lever using force!
5.10.1 Cause
Cause for this is the position of the cam disk # 109 whose cams are positioned precisely under the roller
# 143 while the welding mechanism is lowered. As a result, this prevents the welding mechanism from swinging
back. As the position of this cam is generally monitored by the electronics, this can only occur under the following
circumstances:
●
Power failure during the welding procedure caused by a loose contact or removing the rechargeable battery
during the welding procedure.
●
The mechanism is blocked. The nominal position of the cam disk cannot be approach as a result of this. The
device outputs an E37 error message. (E50 when pulling the rocker lever shortly before reaching the cam zero
point).
●
Micro switch # 103 has a defect
The electronics have missed the zero point for determining the cam position.
The device outputs an E 53 error message.
● The power transmission from the motor to the cam disk is completely interrupted or has significant slippage.
Depending on the degree of interruption, an E53 error message can be given.
5.10.2
Rectification
The blockage can be solved in the following manner. After this, the root problem must be identified according to the
preceding list and corrected accordingly.
ATTENTION
The tool reset may only be performed if the rocker lever is blocked.
Never attempt to lift the rocker lever by force!
►
Place the enclosed 3 mm hex. socket-head key (1)
through the bore hole in the base plate directly onto the
cylinder screw located underneath (see arrow).
►
Perform ten full rotations in the counter-clockwise
direction
. This requires a little physical effort.
►
Lift rocker lever (2).
– The welding mechanism should now pivot upwards.
