13.0 TROUBLESHOOTING
PROBLEM 1: THE SCREW BOLT FEELS TIGHT TO
ROTATE.
SOLUTION: Ensure there is grease present on
screw bolt.
PROBLEM 2: THE FRICTION PAD ON THE SWIVEL,
AT THE BASE OF THE SCREW BOLT,
IS ROTATING ON THE FLANGE
CIRCUMFERENCE.
Note: The tool should not be used
if the friction pad is rotating on the
flange circumference.
CAUSE: The swivel bearing is dirty or seized.
SOLUTION: The swivel should be stripped down,
cleaned, greased and reassembled.
If the problem still occurs replace
the swivel assembly (see repair parts
sheet).
PROBLEM 3: THE FRICTION PAD IS SLIDING ON
THE FLANGE CIRCUMFERENCE AS
THE JOINT IS ALIGNING.
CAUSE: Grit or dirt on wing, roller bearings
require greasing. The tool has reached
full extension.
SOLUTION: Ensure the rollers are rotating freely
on the wing of the tool as it extends
out. If they are not, strip tool, clean
and grease rollers and wing. (see
paragraph 12.0, Lubrication and
Maintenance).
If tool has reached full extension, the
joint will most likely be outside of the
ATM-4 range.
PROBLEM 4: THE TOOL IS ATTACHED AND
APPEARS TO BE FUNCTIONING
PROPERLY, BUT THE JOINT WILL
NOT ALIGN.
CAUSE: Hidden obstruction on the joint or
surrounding pipe, the load required to
align the joint is greater than that of
the ATM-4 (i.e. 4 Ton [40 kN]).
SOLUTION: a. Check the area around the joint for
obstructions.
b. It may be that the required pressure
to align the joint is greater that the
4 ton [40 kN] capacity of the tool.
In this instance another method to
align the joint should be adopted.
