12.0 TROUBLE SHOOTING
Problem 1:
The friction pad is sliding on the circumference of the
opposite flange as the ATM-5 is aligning the joint.
Cause:
Grit or dirt on wing, rollers or bearings, wing is at full
extension.
Solution:
A. Ensure the rollers are rotating freely and that there is
no restriction to the rollers on the wing surfaces such
as dirt or grit.
B. Check that the wing is not at full extension when
aligning the joint.
C. Ensure that there is enough extension left to allow
the ATM-5 to expand as the joint is aligned.
Problem 2:
The ATM-5 is attached and appears to be functioning
properly, but the joint will not align.
Cause:
A. There may be air in the hydraulic system restricting
the force on the flanges.
B. There may be something restricting the joint at a
point close to the flanges. The joint may require more
than 5 ton (45 kN) pressure to align.
Solution:
A. See air lock removal in chapter 13.
B. Check the area around the joint to establish if there
is an obstruction to the joint.
C. If the joint requires more force than that of the 5 ton
(45 kN) of the tool then another method to align the
joint should be adopted.
13.0 AIR LOCK REMOVAL
Follow the steps below:
1. Remove the air vent cap on top of the hydraulic
pump and check hydraulic oil level to ensure there is
enough oil to advance the cylinder.
2. Replace air vent cap, but do not tighten the cap. The
cap must remain loose to allow air to enter and leave
the pump during use. The cap should only be
tightened fully when the tool is to be returned to the
carrying case after use.
3. With the air vent cap loose, connect the pump to the
tool with the hydraulic hose supplied within the
carrying case.
4. Stand the tool on a level surface, hold the hydraulic
pump above the tool, close the release valve on the
pump, and prime the pump to advance the hydraulic
cylinder until the cylinder is fully advanced and a
small pressure is achieved.
5. With the hydraulic pump held above the tool, open
the release valve allowing the cylinder to retract fully
back. While the cylinder is retracting any air that is
within the system will be forced up to the pump and
vented out through the air vent cap.
6. Repeat the above procedure three or four times to
ensure that all air is removed and the tool will reach
full working pressure.

15.0 APPLICATION RANGE
Two basic dimensions, A and B, will determine if the
ATM-5 can be used to align the joint. If the flange joint
to be aligned is between 93 mm [3.75 inch] and 228
mm [9 inch] as illustrated by (A), has a bolt hole size of
31,5 mm [1.25 inch] or greater (B,) then the ATM-5 can
be attached and alignment achieved (see fig. 12).
See charts on page 7: by flange type, class and
diameter.
