10 MAINTENANCE
The turnstile maintenance is required once a year and in case of any technical failures
the turnstile must be serviced immediately after repair works. The maintenance should
be carried out by qualified mechanic only after careful study of this Manual.
To do maintenance proceed as follows:
1. Disconnect the turnstile power supply from the AC mains, the folding arms will
automatically fall down.
2. Remove the turnstile top cover (3) from the turnstile housing as described in
Section 6. Lay the cover on a flat steady surface.
3. To access the rotation unit of turnstile barrier arms, take off the bracket with control
board and remote connector block. For this purpose: unscrew 6 screws (3 on
Fig. 15), which fix the bracket on the turnstile housing and accurately take a bracket
aside without damaging connected cables.
4. Inspect the resetting mechanism (a pusher, springs and a roller), optic sensors
and a damper (Ref. Fig. 16).
5. Remove dust from a rotation sensor disc, located in the spacing of the rotation
optic sensors, with alcohol-gasoline blend applied with a cloth. Avoid ingress of
dust into the operational spacing of the optic sensors.

6. Lubricate with machine oil (lubrication points are marked in Fig. 16):
•
four bushes of the resetting mechanism (two – on the rotation axis of the
pusher;
•
two – on the fastening axis of the springs as well as holes in the fastening
parts of the springs); 2-3 drops of oil in each lubrication point.
Attention!
Avoid ingress of lubricant on the rotation sensor disc and the roller surfaces.
