Pipe Wrench Use Guide

Read the warnings and instruc-

tions for all equipment and material

being used before operating this

tool to reduce the risk of serious

personal injury.

• Use personal protective equipment. Always wear eye

protection. Protective equipment such as non-skid safety

shoes, hard hat, etc. used for appropriate conditions will

reduce the risk of personal injury.

• Do not use handle extensions (“cheaters”) or exces-

sive force. These may damage the tool or slip and cause

serious injury.

• Do not use with a threading machine to install or

remove (make or break) fittings. This can cause striking

or crushing injuries.

• Do not use come-a-longs, chain hoists, handle exten-

sions, backhoes, threading machines, drill rigs or

other mechanical, hydraulic or powered devices to

activate pipe wrenches to install or remove (make or

break) fittings. Pipe wrenches are hand tools designed to

be used by hand. Use of these types of devices with pipe

wrenches can result in wrench and equipment damage

and failure from overload and increases the risk of striking,

crushing or other serious injury.

• Do not use a wrench with a bent or twisted handle.

A bent handle indicates the wrench has been overloaded

and is damaged. A bent handle should never be straight-

ened. A wrench with a bent or twisted handle should be

taken out of service.

• Do not modify or alter a pipe wrench. Modifying a pipe

wrench may result in wrench failure and serious injury.

• Do not overreach. Keep proper footing and balance

at all times. This enables better control of the tool in

unexpected situations.

• Do not hit a wrench with a hammer to break loose

a fitting. Impact loading may damage the wrench, chip

wrench teeth or cause serious injury.

• Do not misuse pipe wrenches. Other uses increase the

risk of serious injury.

Do not use as a hammer.

Do not apply a side load to the handle.

Do not use as a lever, lifting device or bender.

Do not use the wrench on hard, square, hexagonal or

other non-round material.

Pipe Wrench Use Guide

Pipe wrenches are designed to turn pipe. Improper use

may result in damage or injury.

• Do not use near flame or high heat. Teeth on the hook

or heel jaw could become soft. This may result in chipping

or flattening of the teeth. This reduces its strength which

may result in failure.

• Properly support the work piece. Failure to properly

support the workpiece can cause falling or shifting pipe

and equipment and increases the risk of injury.

• When using pipe wrenches with other Ridge Tool

products, follow the instructions supplied with that

product.

• Stay alert, watch what you are doing and use common

sense when using tools. Do not use when you are tired

or under the influence of drugs, alcohol or medication.

A moment of inattention while operating tools may result

in serious personal injury.

• Do not let familiarity gained from frequent use of tools

allow you to become complacent and ignore tool safety

principles. A careless action can cause severe injury in a

fraction of a second.

• Pipe wrenches are general use tools that can be used in a

variety of situations. Ridge Tool cannot provide guidance on

all possible use situations. Users must evaluate the specific

work scenario and apply training, good work practices and

methods to reduce risk.

NOTICE Selection of appropriate materials and installation,

joining and forming methods is the responsibility of the system

designer and/or installer. Selection of improper materials and

methods could cause system failure.

Stainless steel and other corrosion resistant materials can

be contaminated during installation, joining and forming. This

contamination could cause corrosion and premature failure.

Careful evaluation of materials and methods for the specific

service conditions, including chemical and temperature,

should be completed before any installation is attempted.

Inspection/Maintenance

Daily before use, clean the wrench to aid inspection and

improve control. Handles and gripping surfaces should be

clean, dry and free of oil and grease. Inspect the wrench for:

Pipe Wrench Use Guide

• Proper assembly and completeness

• Wear. Clean the jaws with a wire brush. Teeth should be

clean and sharp. Replace jaws if teeth are worn to reduce

the risk of slippage

• Damage such as cracks, cuts, nicks, deformation

• Bent or twisted handles. Do not straighten handles.

Wrenches with bent handles have been overloaded and

should be removed from service.

• Modification of any kind, including grinding or welding.

Modification can weaken a wrench.

• Discoloration or other indications of heat damage

• Proper operation. Hook jaw should move smoothly when

the nut is turned. Springs in housing should allow hook jaw

to pivot slightly. This allows proper ratcheting action of the

wrench.

• Other issues that could affect safe use.

If any problems are found, do not use until corrected. Remove

worn, bent or otherwise damaged wrenches from service and

dispose of. Only use genuine RIDGID service parts.

Inspect chains for any separation of links or other damage.

Link separation indicates the chain has been overloaded

and should be replaced.

Lubricate all moving parts/joints as needed with light lubri-

cating oil. Wipe up excess oil. Keep non painted parts well

lubricated with oil and store in a dry place.

Set-Up

Inspect the material to be worked with. Pipe wrenches are

designed for use on round pipe and threaded fittings, or

soft round stock. Do not use on hard (325 BHN maximum),

square, hexagonal or other non-round material. The jaw

teeth should penetrate the stock to properly grip. Wrench

may slip on hardened material or the teeth may chip when

used on hex or square stock.

Pipe wrenches can apply high forces to pipe that can crush

or oval the pipe, especially thinner wall pipe. Pipe wrench

jaw teeth grip by digging into the material of the pipe. This

will mar the surface finish of the pipe and could create sharp

edges and cut hazards.

Choose a proper size and type of pipe wrench for the job. Do

not use on pipe larger than rated for. (See Chart 1)

Make sure the work piece is stable and well supported to

prevent tipping and falling during use.

When using a pipe wrench of any size, a gap must be main-

tained between the shank of the hook jaw and the work

piece. (Figure 3) This permits the two gripping points (heel

jaw teeth and hook jaw teeth) to produce the gripping action

of the wrench. Allowing the shank of the hook jaw to contact

the work piece greatly reduces the gripping action and can

cause slippage. It may also result in the failure of the hook

jaw. (Figure 4)

Adjust the hook position by rotating the nut as needed.

Wrench should be square to the pipe. Do not use with the

wrench at an angle to the pipe.

Figure 4 – Wrench Too Small For Work Piece, Hook Shank

Touching Work Piece.

RapidGrip® Wrench

When using a RapidGrip wrench, be sure to center the work

piece in the “v” of the hook. If the work piece is not in contact

with both sides of the “v”, it can reduce wrench gripping action

and may result in failure of the hook.

Figure 5 – Using a RapidGrip Wrench

Compound Leverage Wrenches

Mount trunnion on pipe close to threads, with shank of trun-

nion pointing towards the threads as shown in Figure 6A.

Run chain over pipe, hook into ears of trunnion and securely

tighten with chain screw handle. With wrench head properly

adjusted for work piece size (maintain gap between hook jaw

shank and work piece), place the end of the wrench handle

over the shank of the trunnion. Place the wrench head on the

work piece. Secure the wrench handle to the trunnion shank

with the cotter pin. (Figure 6B)
