The Gray Chain 3570 AIR offers the ultimate in simplicity and rugged design.
Designed to be compact and self contained; the GrayChain 3570 does not require a
stand-alone power pack. All the gripping pressure and spinning torque are generated at the
drill pipe spinner. In standard rig installations a spring hanger assembly is provided.
Keep in climate controlled environment where possible. The GrayChain 3570 should be
palletized and covered to be kept dry and free from moisture. The GrayChain 3570 should
be inspected for any rust or corrosion especially after storage and before use. All points of
any type of rust or corrosion should be properly maintained or replaced prior to start up.
Apply grease to all lubrication points prior to start up. Any parts showing signs of rust or
corrosion should be thoroughly inspected prior to operation.

Hanging the Spinner
The GrayChain 3570 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.
Use of the GrayChain 3570 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 drawworks
(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 GrayChain 3570 will rotate drill pipe in
both directions and consequently swing in
either direction. The GrayChain 3570 must
be equipped with two backup lines. These
two backup lines or cables need to be
attached to derrick legs or a comparable
structure. Attachment should be made
so that the swinging movement of the
spinner is restricted to less than 1’ 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 GrayChain 3570 to its desired
location.
Attaching the Fixed Line
Use a cross member to attach the xed line to position the hang-off
cable about 2’ to 3’ from the pipe centerline. Across from the driller is where the GrayChain
3570 should be positioned.
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!
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
Figure 2

INSTALLATION

Back Up Cables
The two lugs at the back of the GrayChain
3570 are to be used with two back up
cables. The two lugs at the end of the
GrayChain 3570 are to be used with two
back up cables. These two cables will
restrict the rotational movement to 1’ in
either direction. It is very important that
these cables do not cross. Using only one cable would allow the possibility of the GrayChain
3570 swing into the operator causing injury.
Connecting the Air Line
In an area that is easily accessible and well protected, run a 1½” air line up to the rig oor.
This will aid in maintenance. Typically a 1½” airline should be run. A valve is required at this
point in order to shut-off air when maintenance to the tool is required. Install a 1¼”, 200
psi minimum, air hose from the valve to the spinner. Keep the hose and piping as short as
possible with as few ttings as possible. Blowing out the line prior to installation will remove
debris or moisture from the system.
Connect the air line. As listed in the
description, the GrayChain 3570 requires
optimum 100 psi air pressure. When
installing, use the least amount of ttings
as possible and route the air directly from
the supply keeping the distance as short as
possible.
Shut Off Valve
Use a 1¼” shut-off valve attached to the
supply line.
Balancing Screw
The tool can be leveled by turning the
leveling screw atop the stationary hanger.
Level the spinner by turning the balance
screw.

Operation
1. With the doors open, swing the GrayChain into position on the drill pipe. Bring the 3570
to the correct height. Approximately 12” above the tool joint, position the 3570 onto the
pipe making sure that you do not run the tool on the pipe upset or tool joint.
2. Close the doors, clamping the spinner onto the drill pipe. This is accomplished by
pushing the door valve handle in. The door valve is located on the bottom left of the
spinner.
3. Activate the rotation of the drilling by pulling the throttle valve handle out. Rotation of
the drill pipe can be changed (spin in, spin out) by reversing the position of the Quick
Disconnects located at the motor.
4. Open the Spinner doors by pulling the door valve lever. The 3570 can now be safely
swung away from the pipe.
Changing Pipe Sizes
The GrayChain 3570 has a unique and easy method to set up the spinner for various drill
pipe sizes.
1. Shut off all air to the spinner and bleed off any residual pressure in the door cylinders.
This is accomplished be activating the door valve after the source air has been shut
completely off.
2. To change the pipe sizes simply release the Safety Pin below the chain case. Pull the
adjust roller shaft out of the top of the case.
3. Locate the roller and roller shaft in one of the ve designated slots for the appropriate
drill pipe size.
4. Replace the Safety Pin on the lower shaft. Restore the air supply.

Additional Adjustment
Tension Adjustment
When the chain stretches or is getting too worn to obtain a proper bite, loosen the 1” Hex
Head Cap Screws on the motor mount, loosen the lock bolt on the Chain Retainer and move
the motor toward the rear of the spinner. Reposition chain retainer and retighten lock bolt.
Oversized Roller
If motor is adjusted all the way to the rear and proper bite is still not obtained, replace
standard idler roller with the 4” spare oversized idler roller located inside the case on left
side. This should allow you to operate until a new chain is purchased.
NOTE: Always check chain for tightness. Do not allow for
slack. Motor capscrews must be tight.
NOTE: Take the time to make sure the back up lines are
properly attached and that safety regulations are observed.
