Introduction
Hawk's design philosophy is simple: Design with the end user in mind. Make it tough,
dependable and easy to maintain.
Hawk has designed the HawkJaw with this same simple formula.
FEATURES
The HawkJaw 100K-ALS is a hanging unit that will spin, make up and break out drill pipe. It is
revolutionary because the tool spins and makes up drill pipe or breaks out and spins drill pipe in
12 seconds or less. A patented self-energized grip system provides consistent torque values to
the drill string. Consistent torque ensures that wash outs and "post tightening" down hole do not
occur under normal conditions.
A patented adjustable wrench system eliminates the need for separate jaws, spinning wrench
rollers or gripping dies. The HawkJaw's modular design enables the unit to be maintained on the
rig floor.
SAFETY
The HawkJaw 100K-ALS provides a fast, safe and efficient method of spinning and make up or
break out and spinning. It eliminates costly and dangerous spinning chain and rig tong accidents.
TIME AND LABOR SAVINGS
The HawkJaw improves trip time over any comparable torquing and spinning device in the
industry. The unit easily adapts to any land or offshore rig because it hangs in the derrick.
Handles mounted near the control buttons enable one rig hand to move the hanging unit on and
off the pipe.
Control buttons are used to grip, torque and spin drill pipe. Drillers and operators of the
HawkJaw 100K-ALS work more efficiently and suffer less fatigue on long round trips. The unit
saves trip time because the HawkJaw breaks out and spins in 12 seconds or less, and makes up
and spins in 10 seconds or less. Crew fatigue is reduced, pipe is properly torqued and the work is
efficient.

Hanging Cable Location
1. Anchor the hanging cable to a point as
close to the derrick crown as possible.
The longer the hanging cable, the easier
the HawkJaw is to move on and off the
drill pipe.
2. Locate the cable hang point as high
above the center of the rotary table as
possible. The cable must hang within
2'-3' ft. of the rotary table center.
Installatio
n
9Installation
NOTE
The hanging cable must permit the
HawkJaw to move from the drill pipe
connection to the mouse hole connection to
the HawkJaw rest position (3'- 5' ft. away
from the rotary table).
HawkJaw Location
1. Place the HawkJaw on the side of the
rotary table away from the setback
zone. This allows the drill pipe stands
to swing straight from pick-up to
stabbing.
2. If possible, place the HawkJaw on the
opposite side of the setback zone. If
the rig has dual setback zones, Step 1
applies.
3. The HawkJaw may rest on the rig floor
3' -5' ft. away from the rotary table.
1. 5/8" diameter steel cable.
2. Appropriate hanging cable hardware
for 5/8" diameter steel cable.

Operation
Test#1: Hawk strongly recommends testing
the Low Torque Warning System on every
trip. If this test procedure is not performed,
the drill string could be over torqued.
Disconnect the Low torque warning test
connector (LTC) located as shown. Torque
the first connection. Note the torque gage
needle position; keep the Hawkjaw positioned
on the same connection. Now re-connect the
Low Torque Warning Connector. Re-torque
the connection. The torque gage should
indicate the same reading. If it does not, see
Trouble Shooting page 96.
LOW TORQUE WARNING SYSTEM CHECK
Do not make up pipe with the low
torque warning test connector dis-
connected. This may result in under
torqued pipe in the hole.

The hydraulic pressure is low. Increase the
hydraulic pressure. Do not increase the pressure
over 2500 psi, or the hydraulic fluid will pass over
the relief valve and heat up the hydraulic fluid. This
will cause damage to the HawkJaw and to the
pump, and will severely shorten component life.
Check to make sure the hydraulic power unit is

The Hawkjaw may have an obstructed tank lead-in
hose or quick disconnect. Check the pressure at
the tank out-put port on the Hawkjaw main hydrau-
lic manifold. Pressure readings should not exceed
200 psi. If the pressure reading is above 200 psi,
clear the obstruction in the hose or replace the
quick-dissconnect. Also check belleville springs
#061-022S for correct placement or breakage. See
Drawings pg.106.
The air logic system is flooded with water. Make
sure the hydraulic power unit is shut down. Access
the air logic system. See Maintenance & Repair, p.

the HawkJaw or the pressure relief valve setting on
the hydraulic power unit, the hydraulic fluid will heat
up rapidly.
There is a leak in the hydraulic system. See
Trouble Shooting, p. 89-90.
If there are no leaks in the hydraulic system, and the
pump pressure compensator setting is at 2500psi
on a known, tested hydraulic power unit, and the
hydraulic power unit pressure relief valve is set
400 psi above the pump pressure compensator
setting and the hydraulic fluid still heats up, then
the pressure relief valve setting on the HawkJaw
has been changed. The pressure relief valve adjust-
ment is set at Hawk Industries. Under no circum-
stances should this pressure relief valve be adjusted.
Adjusting the pressure relief valve setting voids
the warranty and can cause severe damage to the
HawkJaw and the hydraulic power unit and
shortens component life. However, if this valve has
been adjusted below 2800 psi, and the pressure
compensator setting is above 2500 psi, the hy-
draulic fluid will pass over the pressure relief valve.
This will heat up the hydraulic fluid rapidly. Properly
set the pressure relief valve adjustment. On a
known, tested hydraulic power unit, set the pump
pressure compensator setting at 2800 psi. Use
an allen wrench to rotate the pressure relief valve on
the Hawkjaw counter-clockwise until the
Hawkjaw pressure gage drops. Now turn clock-
wise. When the gage returns to 2800 psi and
holds, tighten the pressure relief valve lock nut.
Set the pump pressure compensator setting back
down to 2500 psi. See Maintenance & Repair, p. 66,
Drawings, p. 114.
Check to make sure the hydraulic power unit is
producing 2500 psi at 20-35 gpm.

The pressure compensator setting on the power
unit is conflicting with the relief valve setting on
the power unit or the Hawkjaw. This usually means
that the pressure compensator setting on the
power unit is set too high (higher and too close to
the relief valve setting of either the power unit or the
Hawkjaw). If the pressure compensator setting
on the power unit is 2500 psi. , this is correct.
Then the relief valve setting must be slightly
increased, so that no pre-mature release of fluid
occures. See Trouble Shooting pg. 92. First screw in
the relief valve on the power unit one-half turn.
If the hose wipping continues, make the same
adjustment on the Hawjaw relief valve. If the
wipping still continues, the power unit compen-
sator system or pump is most likely the prob-
lem. Consult the power unit manual or the
factory for adjustment or repair information.

NOTE
To adjust the Spinner move forward, close and open sequence:
1. Use a 5/32" allen wrench to rotate the Push cylinder pressure reducing valve at Port V1
counter-clockwise until refusal.
2. Use a 5/32" allen wrench to rotate the Spinner Door sequence valve at Port V2 clockwise until
refusal.
3. Use a 1/4" allen wrench to rotate the Spinner retract needle valve at Port V9 clockwise
until refusal.
4. Use a 5/32" allen wrench to rotate the Spinner motor sequence valve at Port VG/S on the main
hydraulic block clockwise until refusal. See Maintenance & Repair, p. 67.
5. Set the Selector switch to Break. See Operate, p. 28. Adjust the spinner to the drill pipe tube
OD. See Operate, p. 25. Place the HawkJaw on the drill pipe connection. See Operate, p. 26-
27.
6. Press the Spin button. Rotate the Push cylinder pressure reducing valve at Port V1 clock-
wise until the spinner moves forward and the chain touches the pipe. If the chain forces the
HawkJaw away from the pipe, back off on the adjustment until the spinner chain touches the
pipe without forcing the Hawkjaw back. The spinner will close if you hold the spin button too long.
7. Rotate the Spinner Door sequence valve at Port V2 counter-clockwise until the spinner
doors begin to close as the spinner chain touches the pipe. For each adjustment, press and
hold the Spin button to test the adjustment. Continue to rotate the adjustment counter-
clockwise until the spinner begins to close before the chain touches the pipe. Rotate the
adjustment clockwise until the spinner begins to close as the spinner chain touches the
pipe. Lock in the adjustment.
8. Adjust the needle valve V9 clockwise until the spinner opens smoothly while pulling back.
For each adjustment, press and hold the Spin button until the spinner doors close. Release the
Spin button to test the adjustment. If the rollers grab the pipe while retracting, adjust the
needle valve clockwise. If the chain forces the HawkJaw backwards while retracting,
adjust the needle valve counter-clockwise.
9. Adjust the spinner motor sequence valve at Port VG/S. Use a 3/16" allen wrench to rotate the
sequence valve counter-clockwise until the chain moves before the doors close. Next, rotate the
adjustment clockwise until the spinner doors close before the chain moves. Rotate one half-
turn clockwise. Lock in the adjustment. See Maintenance & Repair, p. 67, Drawings, p. 114.
