Increasing the tensile force of the cable reel
The more the camera cable in unwound, the more power you need to retract the cable. For this purpose you can increase the tensile force of the
cable reel:
• Turn the rotary control POWER forwards to increase the tensile force.
The LED bars show you the increase in the tensile force.
• When the manhole is reached, carefully pull the cable pulley and the crawler out of the manhole.
• Firstly, hose the crawler thoroughly with water – afterwards loosen plug and screw connections.
WARNING!
Risk of damage of the camera cable!
When you retract the crawler, always make sure that the cable is strained. Otherwise there is a risk that the crawler runs over the
cable and causes damage. Thus the crawler might get stuck in the manhole.
