Safe Pract ices and Procedures
Responsibility
"It is the responsibility of the employer to train the employee in the proper selection and
usage of tools, chains, etc., and to ensure that they are selected and used in that manner. In
many instances, injury results because it is assumed that anybody knows how to use common
hand tools. Observations and the record show that this is not the case. A part of every job
instruction program should therefore be detailed training in the proper use of hand tools (and
of all other special tools and equipment needed to accomplish the job)." - ( Source: National
Safety Council)
"Employers are responsible for the safe condition of tools and equipment used by employees,
including tools and equipment which may be furnished by employees." - (Source: OSHA
1910.242A)
Replacement Parts
Use only PETOL™ replacement parts - no other parts are of comparable strength, quality and
interchangeability.
Safety
While we pride ourselves on the quality and dependability we build into GEARENCH™
tools and products, we caution users that it is only prudent to know and follow the simple
rules of safety when using our products, or anyone else's.
Always follow safe practices and procedures in accordance with the recommendations of
OSHA, The National Safety Council (NSC), The Hand Tools Institute (HTI), The National
Association of Chain Manufacturers (NACM), The International Association of Drilling
Contractors ( IADC), Et c. All applicable Governmental rules, regulations or restrictions, now
in effect or which may be promulgated, take precedence over the suggestions in this
publication. The information in this publication is designed to supplement standard safe
practices and procedures, not in lieu of, or replacement thereof.
Safe Practices
(Source: The National Safety Council)
Failure to observe one or more of the following five safe practices accounts for most hand
and powered tool accidents:
1. ALWAYS WEAR SAFETY GOGGLES TO PROTECT EYES
2. SELECT THE RIGHT TOOL FOR THE JOB
3. KEEP TOOLS IN GOOD CONDITION
4. USE TOOLS CORRECTLY
5. KEEP TOOLS IN A SAFE PLACE
4
Page 7
Safety Goggles must always be worn by persons in any area where hand and powered tools
are being used.
Never apply ex cess leverage t o a wrench o r tool b y means of a "Cheater Bar". Never strik e
wrenches and tools with hammers or other objects.
All tools should be kept clean, inspected on a regular basis, and replaced when th ey show
signs of wear.
Be especially careful not to place yourself in a position that could result in bodily injury in
the event of a failure. Brace yourself firmly and pull rather than push when wrenching. (If
necessary to push, do so with the flat of the hand rather than gripping around the wrench.)
Never stand under or near loads being hoisted off the ground.
READ SAFE PRACTICES AND PROCEDURES MANUA L, CATALOG INFORMATION
AND PRODUCT LABELING PRIOR TO OPERATION.
Spinning and drill pipe chain, cathead chain, and the PETOL™ Connecting Link attachment
are designed for the specific purpose for which the name indicates. Chains and attachments
that are to be used for any other purpose should be selected in accordance with the
recommendations of ASTM, NACM, Rigger's Handbook, and the commercial chain
manufacturer's technical manuals.

Responsibility of Distributors
IT IS THE RESPONSIBILITY OF THE PURCHASE RS OF GEARENCH PR ODUCTS TO
CONVEY THE INFORMATION IN THIS PUBLICATION AND ANY OTHER
INFORMATION RELATING TO THE INDIVIDUAL PRODUCT, THROUGH THE
CHANNELS OF DISTRIBUTION, DOWN TO AND INCLUDING THE INDIVIDUAL
USING THE PRODUCT
NOTE:
In view of the fact that the actual use determines whether safety requirements have
been met, the ultimate responsibility to comply rests with the end user.
The service life of leaf chains can be altered by a variety of adverse operating conditions.
The following information discusses the most important of these conditions for consideration
when operating or scheduling replacement of leaf chain systems.
Overloading / Shock Loads / Side Loading
Attempting to “inch loads which are beyond the rated capacity of the tool.
Striking the tool with a hammer or other object while force is being exerted in an attempt to
loosen a “frozen” joint.
Side pull can be caused by pulling or pushing on the tong in a direction that is not along a
perpendicular plane, unleveled mounting of the tong or vise, inadequate support of the part
being broken out, and improper seating of the part being broken out in the tong or vise.
Improper seating will occur when the diameter of the part is not consistent within the width
of the tong or vise jaw.

Page 9
Environmental Conditions
Wrench chains operate in widely varying environments, from wet outdoor conditions to
mildly or highly corrosive industrial atmospheres. They can also be exposed to abrasives
such as sand or grit.
The possible effects include:
Moisture - Corrosion and rust reduce chain strength by causing pitting and cracking.
Temperature - Very cold temperatures reduce chain strength by embrittlement.
Chemical Solutions or Vapors - Corrosive attack of the chain components’ grain structure
and/or the mechanical connections between the chain components (crevice corrosion)
may occur. Cracking often is microscopic. Propagation to complete failure can be
eventual or sudden.
Abrasives - Accelerated wearing and scoring of the articulating chain members (pins and
plates) may occur, with a corresponding reduction in chain strength. Due to
inaccessibility of the bearing surfaces (pin surfaces and plate apertures), wear and scoring
are not readily noticeable.
These conditions, when coupled with normal chain wear and inherent residual stress
(normally in the chain as constructed), can result in environmentally assisted failure. It is
impossible to predict chain life under complex conditions, as the degree of hostility and its
effects are dependent on many variables such as temperature, time of exposure, concentration
of corrosive atmosphere or medium, degree of abrasive wear, etc. Establishing the degree
and frequency of unpredictable dynamic loading is also difficult.
Normal Life Expectancy
A leaf chain’s normal life expectancy can be expressed as a maximum percent of elongation.
This is generally between 2% and 3% of pitch. As the chain flexes back and forth, the
bearing joints (pins and inside link plates) gradually wear from articulation. As with all steel
bearing surfaces, the precision hardened steel joints of leaf chain require a constant film of
oil between mating parts to prevent wear and to resist corrosion.
7
Page 10
Lubrication
One of the most important but often-overlooked factors is adequate lubrication. In addition
to reducing internal friction, maintaining a film of oil on all chain surfaces will inhibit rusting
and corrosion, This is important as corrosion of highly stressed, hardened steel chain
components can cause a major reduction in the load capacity of leaf chain and result in link
plate cracking.
Protection from corrosion is important in storage as well as in service. The factory lubricant
applied to PETOL™ Chain is a “Fingerprint Neutralizing Water-Displacing Corrosion
Preventative”. This is an excellent rust and corrosion inhibitor for chains in storage. When
installing these chains new, do not attempt to steam clean or degrease this lubricant. A grade
of SAE 30 or 40 weight, non-detergent motor oil should be used as supplemental lubricant
and a film of this oil should be maintained on all surfaces and internal bearing joints. Also,
do not attempt to paint new chains. Though painting may help inhibit corrosion, it will seal
off critical clearances and restricts oil from reaching the pin surfaces where it is needed for
good joint lubrication.
When operating in dusty environments, lubricated chains will accumulate a paste-like
buildup of grime. At periodic intervals, this buildup should be removed by cleaning and the
chain should be immediately re-lubricated. Do not use caustic or acid type cleaners; use a
stiff brush and a certified safe petroleum base solvent.
Periodic Inspection List for PETOL™ Special Chain
1
. PRIOR TO EACH USE, LEAF CHAIN AND TOOLS SHOULD BE
INSPECTED FOR SERVICEABILITY AND LUBRICATION.
2. USE ONLY PETOL™ AND TITAN™ REPLACEMENT PARTS - NO
OTHER PARTS ARE OF COMPARABLE STRENGTH, QUALITY, AND
INTERCHANGEABILITY.

Safety Precautions
1. Always wear safety goggles to protect eyes.
2. Select the right tool for the job.
3. Keep tools in good condition.
4. Use tools correctly.
5. Keep tools in a safe place.
6. Wear protective clothing, gloves and safety shoes as appropriate.
7. Use lengths of assembled chain. Do not build lengths from individual components.
8. Do not attempt to rework damaged chain by replacing only the components obviously
faulty. The entire chain may be compromised and should be discarded.
9. Never electroplate assembled leaf chains or components. Plating will result in failure
from hydrogen embrittlement.
10. Do not weld any chain or component. Welding spatter should never be allowed to
come into contact with chain or components.
11. Leaf chains are manufactured exclusively from heat-treated steels and therefore must
not be annealed. If heating a chain with a cutting torch is absolutely necessary for
removal, the chain should not be reused.
12. Inspect chains frequently and regularly for link plate cracking, pin turning, pin
protrusion and corrosion.
13. Use only PETOL™ & TITAN™ replacement parts to ensure proper strength.

Operation
The typical application of one Bull Tong is shown in the figure below. Normally an
additional tong is used as a backup. The backup tong is not shown for clarity. The tong will
exert torque in the direction shown. The tong will ratchet when moved in a direction
opposite to the line pull. Ratcheting is used when the tong must be pulled more than once to
completely makeup or breakout the connection.
Suspension
When working vertical pipe, the tong should be suspended by the attached hanger. Adjust
the hanger to obtain the best possible balance of the tong. Always use a suspension line of
adequate capacity to safely hold up the tong during operation.

Weld Repairs
Scope:
This procedure is to be followed for minor repairs of crack indications in heat treated alloy steels. A
weld repair shall be considered minor when the depth of the cavity does not exceed 30% of the actual
wall thickness or 1 inch, whichever is smaller, or when the extent of the cavity does not exceed
approximately 10 square inches. Major weld repairs must be performed by GEARENCH™ or an
approved repair center using appropriate procedures followed by full heat treatment and load testing.
Application:
This procedure applies to steel castings, forgings and, wrought with carbon content between 0.15%
and 0.31%.
Weld preparation:
The crack indication is to be removed by carbon arc gouging, grinding, or machining until all
indication is removed. Magnetic particle inspection shall be used to verify that the crack indication
has been removed.
Filler material and process:
Repairs made with the FCAW process shall use a filler material of class E120T5-K4 or equivalent
with CO2 shielding gas. Repairs made with the SMAW process shall use a filler material of type E12018-M. All welding is to be performed by a qualified welder.
Preheat:
Preheat the weld area to 300°F minimum.
Interpass temperature:
The interpass temperature is to be 600°F maximum. All weld slag to be removed prior to application
of additional layers by chipping, grinding or wire brushing. Do not peen the weld repair.
Post weld heat treatment:
Do not allow weld to cool below 300°F before stress relief. Post heat immediately after welding to
1010 - 1040°F for 1 hour per inch of thickness, 2 hours minimum at temperature. Water quench after
stress relief.
Weld blending and inspection:
The weld is to be ground flush with the adjacent parent material. The weld is to be inspecte d by
magnetic particle to verify that the weld area is free of all crack indications.
