20.
Perform a full functional test of the equipment including, if applicable, backup components and float frame components. Report
and correct any hydraulic leaks from the hydraulic valve bank, or from any hydraulic cylinders that are used.
21.
If using a frame-mounted tong and backup system, raise the tong off the beams that it is resting upon. Remove the beams
and protective cloths - inspect the paint on top of the backup and the bottom of the tong to ensure it has not been damaged
by the beam.
22.
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.
NEVER OPERATE YOUR EQUIPMENT WITH A BYPASSED OR MALFUNCTIONING SAFETY DOOR
23.
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.
24.
When all of the previous steps are completed, you may return your re-commissioned equipment to service.
