Hanging the Spinner
The GraySpin Mark 40 should be hung using a wire rope that is ½” or
greater and that is in accordance with acceptable practices. Attach
the wire rope through the shackle at the top of the spring hanger
assembly. Figure 3
Use of the GraySpin Mark 40 without the spring hanger assembly will
shorten the life of the tool and cause improper operation which may
lead to accidents. Disregard if there is a counterbalance in use.
The position of the spinner should be located between the rotary table and draw-works
(toward the off-driller side) about four feet back from the center of the rotary table. It should
hang four to ve feet above the oor as to contact the drill pipe and not the tool joint. The
spinner should be easily pulled on and off the drill pipe and be completely out of the way
when not in use.
The GraySpin Mark 40 will rotate drill pipe in both directions and consequently swing in
either direction. The GraySpin Mark 40 must be equipped with two backup lines. These
two backup lines or cables need to be attached to derrick legs or a comparable structure.
Attachments should be made so that the swinging movement of the spinner is restricted to
less than one foot in either direction.
Attaching to the Mast
Using a ½” hang-off cable attached to the mast (as high as possible) will allow an easy free
swing around the wellbore. The higher up the xed line is, the easier it will be to maneuver
the GraySpin Mark 40 to its desired location.
Attaching the Fixed Line
Use a cross member to attach the xed line to position the hang-off
cable about two to three feet from the pipe center line. Across from
the driller is where the GraySpin Mark 40 should be positioned.
Back Up Cables
The two lugs at the end of the GraySpin Mark 40 are to be used
with two back up cables. These two cables will have to restrict
the rotational movement to one foot in either direction. It is very
important that these cables do not cross. Having only one cable
would allow the possibility of having the GraySpin Mark 40 swing into
the operator causing injury.
Figure 3
Figure 4

INSTALLATION
15
Connecting The Hydraulic Line
Typically a ¾” hydraulic pressure line should be run to the rig oor. A valve is required at
this point in order to shut-off ow when maintenance to the tool is required. Install a ½”,
4,000 PSI minimum hydraulic hose from the valve to the spinner. A 1” return line should be
run to the rig oor and connected to the ¾”
return line from the spinner. Keep the hose
and piping as short as possible with as few
ttings as possible.
Supplied with the Mark 40 are a ½”
hi-pressure supply line and a ¾” return to
tank line. The pressure hose has a ½” female
quick disconnect which attaches to a ½”
male quick disconnect at the right side of the
spinner.
The return hose has a ¾” female quick
disconnect which connects to a ¾”” male
quick disconnect on the right side of the
valve.
Balancing Screw
The tool can be leveled by turning the leveling screw atop the stationary hanger. Level the
spinner by turning the balance screw. Figure 4
Pipe Size Adjustment
The GraySpin Mark 40 will initially be set with the arm to cylinder connecting pin placed in
the rear position. This will accommodate most pipe sizes. If it is necessary to move the pin
to the front position, slowly activate the door valve until the pin is lined up past the front of
the top plate. This will occur with the doors
closed (cylinders extended). Disconnect
power source. Remove the locking socket
capscrew and pull the pin out. Rotate the
door to line up cylinder clevis with the front
pin position and replace pin locking cap
screw. Repeat for the opposite door. Reattach
power source.
WARNING: CHECK ALL SPRING HANGER ASSEMBLY
SHACKLES AND LOCK COTTER PINS FOR TIGHTNESS.
WARNING: CHECK SPRING SAFETY CABLES FOR
SOUNDNESS, (TWO REQUIRED). THE SPRING HANGER
ASSEMBLY IS NECESSARY TO ALLOW THE SPINNER TO RISE
AND FALL WITH THREADED TOOL JOINT MOVEMENTS.
WARNING: THE USE OF ONLY ONE BACKUP LINE CAN CAUSE
THE SPINNER TO SWING INTO THE OPERATOR OR FLOOR
PERSONNEL AND WILL CAUSE INJURY. USE TWO BACKUP
CABLES!

Correct Height
Before starting operation with the Mark 40, please make sure the
pipe size set up matches the appropriate pipe O.D. The Mark 40 will
initially be set with the arm cylinder connecting pin placed in the
rear position. This will accommodate most pipe sizes.
Position of the Doors
The doors need to be open to position the tool. To open the doors,
push the door valve lever in. Pulling the lever out will clamp the
doors onto the pipe.
Bring the Mark 40 to the correct height. Proper clearance is ½”
between the pipe and the front rollers.
Approximately 12” above the tool joint, position the Mark 40 on the
pipe making sure that you do not run the spinner rollers on the pipe
upset or tool joint.
Motor Direction
You can change the direction of rotation of the drill pipe simply
by reversing the position of both quick disconnects located at the
hydraulic motor as shown in gure 7.
Throttle
Pulling the throttle control lever out will engage the driver rollers.
There is a lock-out bracket that prevents engaging the motor to turn
the opposite direction thus preventing damage to the operator and/
or the tool. To reverse the direction of the
drive rollers, refer to Motor Direction.
Doors
Pushing the door valve lever will open the
doors allowing the Mark 40 to be swung
away from the pipe.
