WARNING: This tool is designed only for use by qualified operators.
Qualification is obtained through a thorough understanding of the Safety
Warnings and operating instructions as defined in this operating manual.
NOTE: The labor regulations of many states require that the operator of this
tool on a job site be thoroughly trained and certified for competence prior
to operating this tool. For certification procedures, call: DESA Tool Division,
1-800-626-2237 (USA) or 1-905-826-8010 (Canada).
BEFORE USING
1. Always handle the tool as if it were loaded. Before starting work, check that the
tool is unloaded and the muzzle is clear. Never load a tool unless it is going to
be used.

1. Always know the thickness and type of base material into which you are
fastening. Never guess. Test the base material by using the Center Punch Test.
The Center Punch Test is performed by using a hammer to test drive the
particular power fastener to be used into the material. If the point penetrates
easily, the material is too soft. If the point becomes blunt, the material is too
hard. If the material fractures, cracks or shatters, the material is too brittle. Test
fastenings can be made if the material shows a clear fastener impression and
the fastener point is not blunted. Always start with the lowest power load
(Green-Level 3) and proceeding with the order shown in the lower right-hand
figure above. Operators and bystanders must always wear goggles and ear
protection which meet or exceed the accepted standards for adequate protection in your country. In the USA, refer to ANSI standards. In Canada, refer to
CSA standards.

2. Never attempt to drive power fasteners into very hard or brittle materials
including, but not limited to cast iron, glass, tile, stone, brick, or hardened steel.
Materials of this type tend to shatter and create hazard from flying particles.
G 018
3. Never make fastenings in spalled or cracked areas.
G 018
4. Never drive power fasteners into thin or easily penetrated materials unless it is
backed by concrete or steel. When in doubt, such as when base material is
concealed, conduct a Center Punch Test (See page 6). Check continually to
avoid fastening into unsuitable material, especially in older buildings.
G 018
5. Do not fasten through or within 1/2" of predrilled or pre-punched holes.

8. When fastening into masonry walls, always drive into horizontal mortar joints,
never into vertical mortar joints. Be careful. A poorly laid joint may permit too
much penetration, and/or unsatisfactory holding power.
OPERATING THE TOOL
1. Always hold tool perpendicular to work surface.

2. Should the tool fail to fire, hold the muzzle firmly against the work surface for
30 seconds. Release the trigger and remove pressure on the tool while
holding the muzzle against the work surface. Again press the tool firmly
against the work surface and pull the trigger. If the tool still fails to fire, hold
the tool firmly against the work surface for another 30 seconds before
advancing the power load strip. Use remaining loads in strip. Discard power
load strip into water or oil.

3. Always use the spall shield when driving directly into concrete or steel. Always
wear goggles.
