Attention!
General hazardous area. Death or severe injury or significant property damage
can occur if the corresponding precautions are not taken!
2. Inspection of the bolted connection of the worm wheel
Caution!
Installation, connection to the power supply and commissioning may only be
performed by qualified service personnel! The relevant regulations must be
observed!
ZAS0, ZAS1, ZAS2 and ZAS3 are elevator machines with worm gears.
This instruction manual is an amendment to the original operating instruction:

This instruction manual describes the inspection of the bolted connection of the fitting bolt and nut
of the worm wheel for SWG0-, SWG1-, SWG2- and SWG3-gearboxes for ZAS0-, ZAS1-, ZAS2-
and ZAS3-elevator machines.
This Inspection is not a necessary part of the regular maintenance.
Attention!
If it is possible to turn a nut on the fitting bolt or the whole connection of the
nut and fitting bolt the elevator has to be shut down in order to avoid an
uncontrolled movement of the elevator car!

2.1 Requirements for the inspection:
The elevator has to be taken out of service and has to be locked for passenger or goods transport.
2.2 Required tools
SWG0-gearbox respectively ZAS0-elevator machine:
Spanner with size of 16 respectively 17
Work lamp
SWG1-gearbox respectively ZAS1-elevator machine:
Spanner with size of 16 respectively 17
Work lamp
SWG2-gearbox respectively ZAS2-elevator machine:
Spanner with size of 16 respectively 17
Work lamp
SWG3-gearbox respectively ZAS3-elevator machine:
Special spanner with size of 21 respectively 22 based on a bent combination spanner
(see drawing)
Work lamp
2.3 Inspection of the bolt fitting of the worm wheel
Attention!
Tools may only be inserted into the open maintenance hole (by removing
name plate) if the elevator is switched off by the main switch, the installation
is protected against restart and the operating brake is closed.
It has to be taken care that no limbs, clothing or other objects can get into
the maintenance hole except the tool.
While working in the maintenance hole, ensure that the operating brake is
closed properly and that the manual hand release is not activated.
During positioning, the worm wheel moves. At this state it is only allowed to
visually locate the position of the nut from outside with a minimum distance
of 30 cm with a sufficient bright work lamp.

2.3.1 Removing the name plate / Opening the maintenance hole
Remove the name plate with the sealing, on the top of the gearbox by removing both hexagon
bolts M6.
Figure 1: Name plate with removed bolts M6 Figure 2: Maintenance hole with removed name plate
2.3.2 Positioning of the worm wheel
Each nut (1) which has to be inspected should
preferably be located in the center of the
maintenance hole.
If this is not the case, then bring the nuts into
position, one by one for the inspection, in
according to point 2.3.3 – inspection of
tightening.
It is recommended to mark the traction sheave
w
ith a colou
r
ed marking to avoid that the
inspection of any nut is missing.
The positioning o
f
the worm wheel should be
done by using the inspection control.
It is an advantage if the inspection speed is
temporarily reduced.

As an option, the empty elevator car can be sent to the lowest floor, by a light and controlled
activation of the manual hand release, the worm wheel can be brought to the required position as
well.
2.3.3 Inspection of tightening
The elevator must be switched off by the main
switch and protected against restart.
Do not activate the manual hand release!
Inspection goal:
Identi
f
ication of loose nuts.
A
pply the suitable tool (2) onto the nut (1) of the
bolted connection and turn clockwise with
moderate force according to the following table
w
ithout any jerk.
On the side of the fitting bolt no spanner is
applied for counterholding.

After the evaluation of the tightening, according to 2.3.4, the next nut has to be brought into
position according to 2.3.2.
The inspection of the bolt connection of the worm wheel of the gearbox, is completed when all 6
nuts of the worm wheel have been inspected according to the described method above.

Information:
A precise inspection with the correct tightening torque of the nuts is only possible with a
disassembled gearbox.
2.3.4 Evaluation of the tightening of the nut
If it is possible to turn a nut on the fitting bolt, or the whole connection of the nut and the fitting bolt,
the screw connection has to be considered as inadequately.
If just one of 6 connections is considered as inadequately, the elevator machine has to be taken
out of order immediately and permanently. The elevator has to be secured against restart.
Attention!
If it is possible to turn a nut on the fitting bolt or the whole connection of the
nut and fitting bolt the elevator has to be shut down in order to avoid an
uncontrolled movement of the elevator car!
2.3.5 Documentation of the inspection results
It is recommended that the documenting of the inspection in the attached inspection protocol (see
chapter 3) is done by the inspection personnel.
