Chapter 4 Opening the Router Chassis
Opening the Router Door
•
When opening the door, alternate loosening bolts on each side of the chassis, in the order shown in
Figure 4-2
, to evenly release the door pressure.
•
When closing the door, do not tighten the bolts on the hinge-side of the door first. Tightening the
bolts on the hinge-side first can place too much pressure on the door hinges.
