PROPER INSTRUCTION A MUST
Would you want to work
around someone using one of these tools who doesn't know the first thing about
it? You could be endangering your life if you did. You also could be risking
your life and the lives of others if you attempt to use this tool without proper
instruction. In many states you must be formally trained and licensed to use
powder-actuated tools. There are several makes of these tools and no two are
just alike. Before using one, thoroughly study the manufacturer's instructions.
MANY HAZARDS INVOLVED
Many hazards are involved in using these tools. These include the
1. Flying particles of dirt or scale, or particles discharged from the
work surface the stud enters.
2. Using too heavy a charge for the material. This can result in the
stud being shot completely through the work.
3. Studs ricocheting if the tool is not held properly or is being used
on too hard a material.
4. Fire hazards from using the tool when flammable or explosive dust or
fumes are present.
5.Using the tool powder charges in fire arms or using firearm blanks in
Test the tool each day
before loading to see that the safety devices are working. Follow the
manufacturer's test methods. If the tool does not work properly, do not use it
until it has been properly repaired. Inspect
the tool before using to ensure that it is clean, all moving parts operate
freely, and the barrel is free from obstructions. Make a thorough study of each
job. Know the types of materials you'll be driving into, so that you can select
the proper stud and cartridge. Also know what is on the other side of a wall as
well as what is inside it, such as electric wires and pipes or wire chases.
Never point the tool at
anyone. Don't let bystanders stand too close to the operator. Clear people from
the area on the other side of partitions being worked on. Don't fire studs into
cast iron, high carbon or tempered steel, armor plate, rock, glazed brick, tile,
Load immediately before firing only. Never carry a loaded tool from one
job to another.
Always wear adequate eye protection when using these tools. This applies
to both you and your helpers.
Hold the tool perpendicular to the work surface.
Don't try to start too close to the edge of the work surface. There is a
chance of material cracking or spalling. Unless the tool manufacturer recommends
otherwise, minimum edge distances of one inch for steel and six inches for
concrete are suggested.
Never place your hand over the muzzle of a loaded tool. Don't rest the
tool against your body when loading or making adjustments.
Don't drop or throw
powder-actuated tools. The chance of accidental discharge is great.
Never fire close to or
through pre-drilled holes. This can cause the fastener to ricochet.
powder-actuated tools, studs, and cartridges in a safe place when not in use,
preferably under lock and key. Don't leave tools or accessories unattended, even
for a short period of time.
The charges are much more powerful than firearm loads and should be used
only in powder-actuated tools.
JAMS AND MISFIRES
Never try to release a loaded tool that has jammed in the firing
position. Place it in a safe place and contact the manufacturer's
If a misfire occurs, hold the tool against the work surface for 15 to 30
seconds. Do not remove the tool from the work surface when opening the tool and
removing the defective load. Check the manufacturer's recommendations for
disposal instructions in case of a misfire. Do not throw loads into trash
containers or leave them lying around.
All types of tools need to be properly maintained to do their job
effectively. Powder-actuated hand tools are no exception. Follow the
manufacturer's instructions for maintenance, inspection, and cleaning.
YOUR LIFE CAN DEPEND ON IT
Powder-actuated tools are work-savers and time-savers. Know how to operate them correctly. Your life can depend on it.
