21.
While rotating the cage plate, ensure that the jaws properly cam. If the jaws do not cam properly, the brake bands need
to be tightened. Incrementally adjust both the top and bottom brake bands EQUALLY until proper cam action is achieved.
13.
Perform a complete greasing of the tong - refer to Maintenance section of the technical manual
14.
Ensure main supply and return connections to the tong are fully made up. Re-connect the remainder of the hydraulic lines,
and, if applicable, the electrical line to the turns counter.
FAILURE TO ENSURE THAT THE SELF-SEALING SUPPLY AND RETURN LINES ARE FULLY MADE
UP MAY RESULT IN CATASTROPHIC EQUIPMENT FAILURE.
NEVER OPERATE YOUR EQUIPMENT WITH A BYPASSED OR MALFUNCTIONING SAFETY DOOR
15.
Perform a visual inspection of the load cell. If using a tension load cell, replace any cracked, broken, or distorted com-
ponents including links and chains. If using a compression load cell, replace any component that has been crushed or
otherwise distorted through compression. Inspect hydraulic line, fittings, and diaphragm seals for fluid leaks.
16.
If applicable, inspect the load cell anchor pins (tension load cell only). Replace the anchor pins if cracking or metal distor-
tion is seen.
If using a stand-alone power unit, start it now - refer to the power unit technical manual for startup procedures. Listen to power unit for
a moment to see if there are any unusual mechanical sounds (rubbing, grinding, excessive pump noise). If using a diesel unit, allow
sufficient time for the engine to reach operating temperature before increasing engine RPM. Once engine is warm, gradually increase
engine RPM until operating speed is reached.
17.
Ensure that supply pressure is at or above the tong’s specified operating pressure, and that the return pressure is less
than 350 psi.
18.
Perform a visual inspection of pressurized hydraulic lines. Document and correct any hydraulic fluid leaks.
19.
Perform a full functional test of the tong (refer to section 2.I.4).
20.
Test safety door feature (if equipped). Open the tong door(s), and attempt to rotate the cage plate at low speed (low gear)
in both directions (makeup and breakout). If cage plate begins rotating, the safety door mechanism is not functional, and
the tong must be removed from service until the safety door mechanism can be repaired. If the safety door is operating
correctly, cage plate rotation will not be inhibited once the door is closed and latched.
