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-2GSR 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-2GSR 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-2GSR 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.

item will be replaced by Hawk Industries. Hawk Industries at its discretion may extend this warranty period.
Replacement of parts will be accomplished either at the factory or at a designated service point.
This guarantee does not include the replacement of parts where failure occurred due to normal wear
and tear or misuse of the tool. Defective parts must be inspected by Hawk Industries, at its Long
Beach plant, before warranty can be honored. Customer must obtain an RGA# (Return of Goods
Authorization) from the California, USA factory.
Hawk Industries' liability is limited to replacement of defective parts only and does not include the
cost of labor, communications, transportation or handling connected with the replacement of such
parts.
Hawk Industries will in no event be liable for consequential damages or contingent liabilities
arising out of the failure of any parts to operate properly.
No expressed, implied or statutory guarantee other than herein set forth is made or authorized to be
made by Hawk Industries.
CAUTION
Factory specifications for hydraulics, pneumatics, lubricants, adjustments and safety precautions as
set forth in the operation and maintenance manual are for the mutual protection of the owner of the
HawkJaw 100K-2GSR and the company. Failure to adhere to these specifications can reduce the
efficiency or life of the equipment and/or cause bodily injury.
Warning
The Hawkjaw includes specially modified valves, fasteners and other components for extreme
environments and service. Any attempt to substitute standard components could reduce reliability
and performance, void the warranty and/or cause bodily injury. Any modification made by any
third party without express written consent of Hawk Industries Inc. shall nullify the existing standing warranty.

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.
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.

WARNING
The HawkJaw is a closed center system which
must have a pressure compensated volume controlled power unit. If the only available hydraulic
power unit is constant volume, then the optional
hydraulic converter kit (Part # 061-J80) is re-
quired. Running the HawkJaw with a constant
volume hydraulic power unit may result in bodily
injury and will cause damage to the HawkJaw
and to the hydraulic power unit.
WARNING
The HawkJaw must receive clean hydraulic fluid.
Running the HawkJaw without a Hawk approved
filter (Part # 061-H25) and installed filter element
(Part # 061-H25A) voids the warranty and severely
shortens component life.
