Introduction

General handling of powder-actuated tools

1. Always point the tool away from yourself and all bystanders.

2. Open the tool before operating to make sure it is not loaded.

3. Never place your hand or any part of your body over the front of the tool.

4. Never operate the tool without checking to see if the barrel is free of obstructions and that

the tool is clean and in good working condition.

5. Never attempt to alter, modify or manufacture parts for use in your Simpson Strong-Tie®tool;

this can cause malfunctions and result in unsafe functioning of the tool. Use only genuine

Simpson Strong-Tie parts, fasteners and powder loads at all times.

6. Always wear eye and ear protection for operators and bystanders. Head protection is

recommended. Serious injury or death can occur if these safety items are not used.

7. Posting a warning sign, “Warning, Powder-Actuated Tool in Use,” is a minimum warning

where PAT tools are in use. Sign to be at least 8" (203.2 mm) by 10" (254 mm) in size with

1" (25.4 mm) font height letters.

8. Always properly brace yourself when working on scaffolding or ladders.

9. Never use powder-actuated tools in ﬂammable atmospheres.

10. Never use the tool for anything other than its intended purpose.

11. Use common sense and good judgment. Know the material you are fastening into,

making certain it is compatible with the powder-actuated tool.

Handling of powder loads and powder-actuated tools

1. Never carry powder loads in the same pocket or container with fasteners

or any other hard objects.

2. Never use powder-actuated loads in ﬁrearms. They are more powerful

than normal small arms ammunition.

3. Never carry a loaded tool from job to job.

4. Never use powder-actuated tools in ﬂammable atmospheres.

5. Never discharge the tool without a fastener. Injury or damage to the tool could result.

6. Never attempt to force a load into the chamber of the tool.

7. Never strike or pry a load.

8. Never leave a loaded tool or the powder loads unattended. Store under lock and key.

General Handling of PAT and Powder Loads

Base material suitability and the center punch test

Before loading the tool or fastening into any material, check the suitability and thickness of the

base material. To check base material suitability, give it the center punch test.

Center punch test

Using the fastener as a punch, take a hammer and strike a solid blow to the actual material you

wish to fasten into, then look for these results:

1. If the point of the fastener is blunted, the material is too hard and is unsuitable. If the material

is too hard, the fastener can ricochet, and possibly escape, striking you or bystanders causing

serious injury or death.

2. If the material cracks or shatters, it is too brittle and is unsuitable. This can result in particles

striking the operator or bystanders, or the fastener could pass completely through the base

material causing serious injury or death.

3. If the fastener sinks into the material with the hammer blow, the material is too soft and is

unsuitable. If the material is too soft, the fastener can pass completely through and strike

someone on the other side causing serious injury or death.

4. If the fastener makes a small indentation in the base, the base material is suitable for

fastening into.

Do not use powder-actuated tools for fastening into these materials:

1. Vertical mortar joints

2. Bricks

3. Hollow block or tile

4. Glazed tile

5. Glass

6. Hardened or tool grade steel

7. Cast iron

8. Welded areas or torch cuts

9. Spring steel

10. Natural rock

Base material thickness

Thickness of the base material is perhaps the most important consideration for good safe

fastenings. In concrete, the thickness must be three times the shank penetration; in other words,

for 1" (25.4 mm) of shank penetration, the concrete must be at least 3" (76.2 mm) thick. In steel,

the thickness must be equal to or greater than the diameter of the shank. Fastening into any base

material, which is too thin, may enable the fastener to pass through and escape — resulting in

serious injury or death.

Making Safe Fastenings

Guidelines for safe fastening

1. Never hold the tool at any angle other than perpendicular to the work surface. Make sure that

no debris is present on the surface.

2. Never set a fastener too close to another installed fastener as this can cause a ricochet.

3. Never fasten less than 3" (76.2 mm) from the edge of unsupported concrete or masonry, or

less than

" (12.7 mm) from the edge of steel, except for speciﬁc applications recommended

by the tool manufacturer.

4. Never fasten into rough, spalled, cracked or uneven concrete. Fasten at least 3" (76.2 mm)

from the outer edge of a spalled area.

5. Never fasten into material that is too hard, such as hardened steel, welds, cast steel, marble,

spring steel, natural rock, etc. This could cause the fastener to shatter and escape and result in

serious injury or death.

6. Never fasten into material that is too brittle, such as glass, glazed brick, glazed tile, slate, etc.

This could cause the material to shatter and result in serious injury or death.

7. Never fasten into material that is too soft, such as wood, plaster, drywall composition board,

plywood, etc. This could cause the fastener to pass through and escape resulting in serious

injury or death.

8. Never leave the chamber loaded. If you decide not to make a fastening after having loaded the

tool, remove both the powder load and fastener from the tool before returning it to its case.

9. Never place your hand or any part of your body over the front of the tool.

10. Never point the tool toward any person, loaded or not.

Prepare for loading

1. Always check prior to operating a tool that it is not loaded with a powder load or fastener.

2. Always check to be sure that the tool is clean. Excessive dirt or debris can cause

accidental ﬁring or misﬁring of the tool.

3. Never load or ﬁre the tool 3" (76.2 mm) from the edge of unsupported concrete or masonry,

or less than

" (12.7 mm).

4. Never use improper powder loads or fasteners in the tool, as this may be unsafe or

damage the tool.

5. Always insert the fastener ﬁrst, and the load last. Make sure you never double load

the fasteners.

6. Always perform the center punch test as described in this manual before fastening into any

unknown base material.

7. Always make a test fastening with the lowest power loads and work your way up in power

as needed.

Powder Loads for PT-27

Before Chambering a Powder Load

Selecting Fasteners and Loads

Only use fasteners and powder loads designed for this tool as supplied by Simpson Strong-Tie.

1. If the powder load does not ﬁre after pulling the trigger, hold the tool ﬁrmly against the work

surface for at least 30 seconds. Carefully remove the tool from the work surface making sure to

point it away from yourself and bystanders. Remove the load and dispose of it in a can of water.

Unﬁred loads must never be thrown in trash containers or carelessly discarded in

any way.

2. NEVER attempt to force or pry an unﬁred powder load from the chamber with a sharp or pointed

object as this may cause an accidental discharge.

3. NEVER attempt to disassemble a jammed tool containing a live powder load. Tag the tool

“DO NOT USE” and store it safely in a locked case. Call your Simpson Strong-Tie®representative

for tool repair.

4. If at any time during the operation of the tool you feel it is not working properly, STOP using it

and call your Simpson Strong-Tie representative.

5. Check the work surface to be sure it is clear of debris. Clear away any debris so that the tool sits

ﬂush on the work surface.

6. Check the work area for explosive or ﬂammable materials. If any are found, remove them before

operating the tool.

7. Check the chamber of the tool to be sure there is no dirt, grit or foreign objects present.

8. Check the nosepiece to make sure you don’t double load it with fasteners and that it is clear

of any obstruction.

9. Any tool found not to be in proper working condition shall be immediately removed from

service and tagged “Defective Tool” until it has been repaired according to the manufacturer’s

instructions.

BEFORE loading the tool, operate it a few times on a solid surface making certain all parts

move freely and that the ﬁring pin clicks when the tool is fully depressed and the trigger is pulled.

Discharging the tool without a load in the chamber will cause “dry ﬁring,” which will not damage

the tool.

Safe Handling Practices of PAT

SAFETY STARTS WITH YOU

As the powder-actuated tool operator, your safety and the safety of those around you should

always be kept in mind. Consider that the least powerful load used in powder-actuated tools

produce approximately ten times the power of a .22 caliber long riﬂe cartridge. Respect this

power as you would a chain saw, a lawn mower or a riﬂe.

There are two types of powder-actuated tools.

CAUTION Powder-actuated tools are capable of fastening into concrete and/or steel. The

fastener enters the work surface with an extreme amount of energy. Make certain not to

misdirect the energy.

Indirect-acting type tool

Indirect-acting type tools work by expanding gases that act directly on a

piston, which drives the piston forward to strike the fastener.

Direct-acting type tool

Direct-acting type tools work by expanding gases that act directly on the

fastener without the use of a piston. Direct-acting tools are no longer

manufactured in North America and are regarded as far less safe to operate

than indirect-acting tools. Simpson Strong-Tie only provides indirect-acting

type tools.
