WORK AREA

1. Operate in a safe work environment. Keep your work area clean, well lit and

free of distractions.

2. Keep anyone not wearing the appropriate safety equipment away from the

work area.

3. Store unused tools properly in a safe and dry location to prevent rust or

damage. Lock tools away and keep out of the reach of children.

PERSONAL SAFETY

WARNING! Wear personal protective equipment approved by the

Canadian Standards Association (CSA) or American National Standards

Institute (ANSI).

PERSONAL PROTECTIVE EQUIPMENT

1. Always wear impact safety goggles that provide front and side protection

for the eyes. Eye protection equipment should comply with CSA Z94.3-07

or ANSI Z87.1 standards based on the type of work performed.

2. Wear the appropriate type of full-face shield in addition to safety googles,

as the work can create chips, abrasive or particulate matter.

3. Wear gloves that provide protection based on the work materials or to

reduce the effects of tool vibration.

4. Wear protective clothing designed for the work environment and tool.

5. Non-skid footwear is recommended to maintain footing and balance in the

work environment.

6. Wear steel toe footwear or steel toe caps to prevent a foot injury from

falling objects.

7. Wear a NIOSH approved respirator when working on materials that

produce hazardous fumes, dust or particulate matter.

8. Wear hearing protection gear with an appropriate Noise Reduction Rating

to withstand the decibel levels.

PERSONAL PRECAUTIONS

Control the tool, personal movement and the work environment to avoid

personal injury or damage to tool.

1. Do not operate any tool when tired or under the influence of drugs, alcohol

or medications.

2. Avoid wearing clothes or jewelry that can become entangled with the

moving parts of a tool. Keep long hair covered or bound.

3. Do not overreach when operating a tool. Proper footing and balance

enables better control in unexpected situations.

SPECIFIC SAFETY PRECAUTIONS

WARNING! DO NOT let comfort or familiarity with product (gained from

repeated use) replace strict adherence to the tool safety rules. If you use

this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Use the correct tool for the job. This tool was designed for a

specific function. Do not modify or alter this tool or use it for

an unintended purpose.

2. Avoid pressuring the jaws together accidentally.

3. To avoid dulling the teeth, never press without a separator between

the jaws.

4. Remove the handle when not in use.

5. Always insert a piece of metal or other material divider between the jaws

when not in use.

6. Only use this device on a surface that is stable, level, dry and not slippery,

and capable of sustaining the load.

7. Do not allow children to use this tool without supervision. This tool is not

a toy.

V 4.0 Metal Shrinker and Stretcher 8623159

8. If any parts become damaged, broken, or misplaced, do not use the tool

until replacement parts have been obtained.

9. The workpiece may be sharp. After bending or cutting workpieces, use

caution. Be aware of sharp edges or sharp shreds of metal that may be

created. Use heavy gloves when handling the workpiece.

UNPACKING

WARNING! Do not operate the tool if any part is missing. Replace the

missing part before operating. Failure to do so could result in a malfunction

and personal injury.

Remove the parts and accessories from the packaging and inspect for damage.

Make sure that all items in the parts list are included.

ASSEMBLY & INSTALLATION

When this manual refers to a part number, it refers to the included Parts List.

1. Secure the tool to a workbench a stand.

2. For portability, the tool may also be clamped into the jaws of a vise.

3. The more rigidly the tool is secure, the easier it is to be used.

4. Four holes, predrilled and tapped into the base, accept M10 bolts

(sold separately).

USING THE SHRINKER AND STRETCHER

For hot rodders and restorers, fabricating body parts in the home shop is often

the only way to go. With good planning, you can reproduce shapes to match

original contours, or design shapes limited only by the imagination.

For an example, replacement headlight assembly mounting flanges can be

made. Most older cars tend to catch and hold moisture, thus rusting out.

Usually so much metal is gone that there is left to rescue. A new, fabricated

part is the only way to go.

First, make a cardboard template, tracing around the headlight opening. The

flanged section went into the shrinker/stretcher shrinking jaws. By

pressing firmly on the handle and moving the metal back and forth, the

jaws’ teeth keep drawing the metal closer and closer, creating a smooth

curve. Keep checking the new piece with the cardboard template, and

within minutes a piece very close to the correct is created.

With some final adjustments on the car, it fits just fine. It took a total of 15

minutes to create this mounting flange.

Compound curves can be made by working the piece on alternating sides.

Both shrinker and stretcher can take care to match work on both sides.

This technique is especially useful when reproducing splash aprons and

other large curved areas.

OPERATION

1. Before fabricating on the shrinker/stretcher, bend the metal to be formed

90°on a sheet metal brake, creating a maximum flange depth that is no

greater than 8 in. (205mm).

2. Make a template out of cardboard or a short piece of wire. A template is

critical to achieve a good fit with minimal filler use.

3. Work the leading edge first. This breaks down the maximum resistance

and permits easy and accurate working afterwards.

4. For the best results and maximum forming power, insert metal only

halfway into the jaws.

5. The bunching or pocketing that typically occurs when shrinking can be

quickly hammered out.

6. Control the pressure exerted on the handle while forming the metal.

7. Move the metal back and forth until the desired radius is obtained.

8. The jaws of the tools are “toothed” to better grip the metal. These teeth

leave slight markings, depending on the hardness of the metal, which can

be removed with an abrasive cloth or wheel.

CARE & MAINTENANCE

CAUTION! Remove any load from the product before performing any

inspection, maintenance, or cleaning procedures.

WARNING! To prevent serious injury from product failure, do not use

damaged equipment. If any problems are noticed, have the problem

corrected before further use.

1. Maintain the tool with care. A tool in good condition is efficient, easier to

control and will have fewer problems.

2. Inspect the tool components periodically. Repair or replace damaged or

worn components. Only use identical replacement parts when servicing.

3. Check all hardware for tightness.

4. Only use accessories intended for use with this tool.

5. Keep the tool clean, dry and free from oil/grease at all times.

6. Maintain the tool’s labels and name plates. These carry important

information. If unreadable or missing, contact Princess Auto Ltd.

for replacements.

WARNING! Only qualified service personnel should repair the tool. An

improperly repaired tool may present a hazard to the user and/or others.

CLEANING

Clean the jaws after every job. Blowing out with an air hose doesn’t do a

thorough job. Vacuuming helps get the filings out. The best way to maintain the

metal former is to disassemble the jaws and clean as follows:

1. Loosen the screws (27) to remove the jaw assembly.

2. Remove the jaws and V-block as a single unit.

NOTICE: Be careful, don’t lose the spring between the jaws.

3. Remove the suspension springs (16).

NOTICE: There is a small jaw opposite a large jaw, top and bottom.

4. Clean the jaws with cleaning fluid and a brush. Do not use a wire brush

or a wire wheel. Always brush in the same direction as the teeth, with

the grooves.

8623159 Metal Shrinker and Stretcher V 4.0

5. Clean the V-blocks (15, 19, 31, and 32).

6. Lubricate the surface between the jaws and V-blocks.

7. Reassemble the tool.

8. Replace the jaws. Be sure that you place the large jaw opposite the small

jaw. Then replace the V-blocks.

9. When not in use for an extended time, lightly oil the jaws to

prevent corrosion.

NOTICE: Remember to clean the jaws after every job.

NOTE: Do not use solvents to clean the unit.

LUBRICATION

Use a light machine oil on moving parts. Oil on a regular basis to reduce friction

and maintain smooth movement.

NOTICE! NEVER use a penetrating oil to lubricate the tool. Penetrating oil

may act as a solvent that can break down the grease and cause the tool to

seize up.

STORAGE

When not in use for an extended period, apply a thin coat of lubricant to the

steel parts to avoid rust. Remove the lubricant before using the tool again.

DISPOSAL

Recycle a tool damaged beyond repair at the appropriate facility.
