material can be removed from the front cover of the upright.
6. Dismantle front cover and control panel for upright.
7. Fit hydraulic hoses marked with red in pump unit.
Ø8 oil return hoses and the hydraulic hoses marked with yellow and blue are to be fitted later on (see fig. 10).
Place loose ends of hoses in a bucket in order to avoid oil spillage.

9. Connection to mains (only to be carried out by authorized electrician)
- Wiring diagram is included in control box.
- Turn main switch on upright into 0-position before starting installation
- Connect according to wiring diagram
- IMPORTANT ! Connect to correct voltage – see fig. 9.
10. Push UP-button and by-passing button (see fig. 14).
Turn main switch on upright into position ”1”. Check that power lamp on control panel is alight.
Check direction of rotation of pump motor by pushing UP-button shortly. If lift does not raise, disconnect power
and interchange 2 phase cables. Try again.
Rsise lift to reuired working height. Fit the hydraulic hoses marked with blue and yellow as shown (fig. 7.) Ar-
range Ø8 oil return hoses together with cables for photocell and top and bottom limit switches forward to requi-

12. Fit cables for photocells in control unit as shown.
13. Fit cables for top and bottom switches in control unit as shown.
14. Push UP-button and by-passing button (see fig. 14) to raise lift to max. height, hereby filling the cylinders with
oil and “driving” air out of the system. Lower lift again to bottom position by pushing the DOWN-button.
Repeat this step as often as necessary to be sure that cylinders have been filled up and all air has been expel-
led from the system. Check oil level and fill up if necessary.
Repeat this procedure once every 6 months.
15. Run the lift up and down a couple of times; note that buzzer is activated a little before the bottom position (see
fig. 15).
Check that lifting height is max. 1950mm – if not: adjust top limit switch according to the operation and mainte-

must be supported.
In case the lift has to be shimmed up more than 5mm, the bottom plates must be grouted.
17. Drill with ø16 holes through bed plates to a depth of 122 mm and clean hole. Insert expansion bolts supplied
