17.0 TROUBLE SHOOTING
PROBLEM 1: THE SCREW BOLT FEELS TIGHT TO
ROTATE.
SOLUTION: Ensure there is grease present on
screw bolt.
PROBLEM 2: THE FRICTION
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 thrust bearing and thrust
washers (see page 11).
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
it's 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
Maintaining the tool).
If tool has reached full extension, the
joint will most likely be out of the
ATM-3 range.
PROBLEM 4: THERE IS NOT ENOUGH ROOM
BETWEEN THE LIFT HOOK AND THE
TOOL BODY TO ACCOMMODATE
THE FLANGE.
CAUSE: The tool is incorrectly adjusted. The
flange is too big.
SOLUTION: It may be that by reversing the lift
hook the problem will be solved. If
not, the flange in question will most
likely be out of the ATM-3 range.
PAD ON THE
15, Lubricating and
PROBLEM 5: 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-3 (ie. 3Ton (27kN)).
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 3 ton (27kN) capacity of
the tool. In this instance another
method to align the joint should be
adopted.
