4.0 SAFETY INFORMATION - ATM-4

IMPORTANT: In all installations the site safety

requirements must be adhered to and that safety

of the operator and, when present, any assisting

personnel is of paramount importance along with the

safety of others including, when present, the general

public.

These instructions are only to cover the safe

operation of ATM-4 during a normal maintenance /

installation operation. All other safety aspects must

be controlled by the operation supervisor.

CAUTION: The ATM-4 must not be attached

to pressure vessel nozzles.

WARNING: Never attach the ATM-4 to a

joint until after the flange bolts have been

loosened and removed. Overloading may

occur if bolts are removed while the tool is installed,

and the resulting force is greater than the safe

working load of the tool.

5.0 MISALIGNMENT DETERMINATION

PROCEDURE

• The ATM-4 MUST NOT be attached to a flanged

joint prior to the misalignment determination

procedure being carried out. Refer to warning

statement in section 4.0.

• Every second bolt should be loosened and

removed around the flange. Continue with this

procedure. Misalignment may not occur until only

a few bolts remain. At this point the direction of

any misalignment should become obvious.

• The ATM-4, once attached, will directly push

against the misalignment, bringing the joint back

into alignment.

Fig. 2

The ATM-4 should be attached at the maximum

point of misalignment.

Fig. 3

The point of attachment is determined by the

direction of misalignment at its maximum point, i.e.,

X or Y.

Fig. 4

Each of the examples here show where the ATM-4

should be attached.

MAX 45°

Fig. 5

If for some reason attachment at X,Y is obstructed,

two ATM-4’s can be used as illustrated. (see Fig. 5)

but must not be placed more than 45° apart.
