avoid tension in the plastic, causing malfunction
or not attaining a satisfactory seal.
To ensure the threads in plastic parts are not damaged:
1. Carefully turn the screw counter-clockwise until it
engages the existing threads in the plastic. The
screw will fall slightly by itself when the threads are
located correctly in relation to the existing threads in
the plastic.
2. Screw in the screw to the correct torque as specified
in
Screw fasteners on page 35
.
6.22 To mount thread plugs
If the threads in plastic parts are worn, thread plugs can
be inserted. A repair kit containing thread plugs and
suitable metal screws is available to order.
CAUTION: Fit the thread plug carefully since
there is a risk that the screw bosses crack.
To mount a thread plug into a worn plastic thread:
1. Make the hole bigger with a 6.6 mm drill to a depth
corresponding with the plug.
2. Mount the thread plug with the screw that comes
with the repair kit and screwdriver.
3. Make sure the plug is screwed in completely so that
a good seal is obtained.
CAUTION: Tighten by hand so as not to
damage the plastic.
4. Fit the plastic parts with the accompanying screw
instead of the old plastic screw.
6.23 To replace the sealing strip
There is one sealing strip between the upper chassis
and lower chassis in the product.
