Section III. DRILLING RIG OPERATION UNDER USUAL CONDITIONS
2-7. Assembly and Preparation for Use. The drilling rig is shipped fully assembled and ready for use. Position the rig on
flat, solid ground that has been cleared and leveled. Before you settle on the final position, check that the mast will have
adequate overhead clearance when raised; consider where the rotary table hole center will be when aligning the rig over
the hole site. Visually check for any damage that may have occurred during transit.
2-8. Initial Adjustments, Daily Checks, and Self Test.
a.
Perform the necessary "before" preventive maintenance checks and services (PMCS): also perform any weekly
or monthly checks and services that may apply.
b.
Check that lubricant levels are in accordance with the PMCS and lubrication charts for the following items:
(1)
Air compressor air/oil separator.
(2)
Hydraulic oil reservoir.
(3)
Drawworks bevel gear case.
(4)
Mud pump drive case.
(5)
Mud pump power end.
(6)
Sub-drive case.
(7)
Force feed lubricator reservoir.
(8)
Water injection pump crankcase.
(9)
Rotary table transmission.
(10)
Rotary table housing.
(11)
Pulldown transmission.
(12)
Air line conditioner lubricator bowl.
c.
Fill the water injection tank with fresh water.
d.
Install a foam container in the bracket on the end of the water injection tank. Cut a hole in the container's lid
and insert the plastic tube from the foam pulse pump.
2-9. Preparation for Drilling.
a.
Mud pits. Remove the primary and secondary mud pits from the support vehicle. Temporarily, set the primary
pit under the rotary table area and set the secondary pit at a right angle to the primary. See Figure 2-26.
Connect the mud pump suction hose to the suction fitting on the secondary pit. When required, prepare mud
storage and settling pits (refer to FM 5-166).
b.
Worker's platforms. Remove the locking bolts from the operator's and helper's platforms. Lower both platforms
to the operating position. Install the locking bolts.
c.
