Assembly and adjustments (continued)
Assembling tube sections
1.
Place powerhead/lower tube assembly
on a clean, flat surface so that both
assemblies fit end to end. The power-
head/lower tube assembly should be
facing positioned with the locking hole
in the tube end facing up.
CAUTION!
Keep the open ends of the tubes clean
and free of debris!
2.
Slip off the protective plastic cover(s)
from the ends of the tube(s), and
loosen the coupler screw knob.
3.
Insert the tool assembly into the cou-
pler, with the tool decal facing up, until
the line of the decal is flush with the
end of the coupler.
4.
Twist the tool assembly back and forth
until you are sure it snaps in place by
the coupler latch.
5.
When the two tube halves are locked
together, press down on the spring-
loaded latch protector and tighten the
coupler screw knob.
CAUTION!
Verify that there is no gap between the
latch protector and coupler.
Disassembling the tube sections
1.
With the unit on a clean, flat surface,
loosen the coupler screw. The spring-
loaded coupler protector should pop up.
2.
Press down on the latch with your finger
or thumb. This releases the coupler lock.
