The top whiffle (5) should not be against either
whiffle stop (6) (7). If either whiffle (1) (5) is
canted so far it is against a stop, take the
TB100J out of service until a qualified service
technician adjusts the wire-ropes.
Check all spring washers (8) at both whiffles to
see that they are squashed completely together.
There should not be any gaps as shown here.
If any set of spring washers is found with gaps,
remove the TB100J from service immediately
and have a qualified service technician repair the
condition.
While you are inspecting the whiffles check the
condition of the wire ropes near the whiffles. The
wire ropes should not have any broken strands
or be distorted in any way.

inches (5 cm) of being flush with the end of the
hose carrier cover (2) and the EMS ENVELOPE
lights (3) (4) should be on.

If the booms stop in the wrong place or the light
does not work correctly, take the TB100J out of
service immediately until a qualified service
technician makes repairs.
