5. Adjustment of Onspot
5:1 Test the Onspot a couple of times down and up. Check that arm and chainwheel
have clearence in moving up and down. Necessary adjustment can be made by
turning the whole Onspot sidewards. Tighten the bolts (C) (see fi gure1:2b) with
200 Nm (20 kpm). See to it that the Onspot equipment
is not
mounted closer to the
vehicle’s movable parts than approx. 15 mm.
Always use the vehicle’s pneumatic system to check that the chain
wheel and arm are moving freely, as manual movements may damage
the cylinder. Ensure that nobody is within the pneumatic cylinder’s
danger zone when it is activated from the driver’s cab.
