smoothly without resistance.
4. Using the handset, open the legs to their widest position.
5. Apply the brake to the rear castors.
6. Using a calibrated 180kg (400lb) weights. Position it perpendicularly under the Upper
Assembly.
7. Attach the weight stack to the Upper Assembly using lift straps.
8. Raise the Weight 2/3 the lifting range. Be vigilant for unusual noises while raising the weight.
9. Deactivate the brakes and close the legs using the handset.
10. Drive the Stand Aid forward and backwards one metre. Make sure that the castors rotate
and roll correctly.
11. Activate the rear castors brakes.
12. Using the handset begin to lower the weight. Before reaching the floor, press the E-STOP
button on the control box to check the safety device is working correctly.
