CLEANING
After the front end of tool is completely disassembled, clean all parts with the
brushes provided. Spray all parts with lubricant. Let it sit for a moment and
then wipe dry before reassembly. CAUTION: DO NOT USE ANY KIND OF
LUBRICANT ON THE MAIN HOUSING OF THE TOOL. DRY BRUSH ONLY.
This is the perfect time to inspect your tool for damage or excessive wear. If
defective or excessively worn parts are found, replace them immediately or
remove the tool from service until they can be replaced.

APPLICATION RESTRICTIONS
1. Always make test fastenings with the lowest power load or power
level & increase as proper penetration requires, overdriving results
from too strong a load or power level, too short a fastener, or a
work surface that is too soft.
2. Never use a tool in an explosive or flammable area.
3. Fasteners should not be driven into spalled areas.
4. Never attempt to fasten into very hard or brittle materials;
surface-hardened or high tensile strength steel, glazed tile, cast
iron, glass block, natural rock, face brick or hollow tile.
5. Never fasten through a predrilled hole.
6. Never fasten into concrete closer than 3 inches from an
unsupported edge unless the specific application is approved.
7. Fasteners shall not be driven into concrete where the thickness is
less than 3 times the penetration of the fastener shank.
8. Fasteners shall not be driven closer than 1/2" from the edge of steel
& never into steel less than 1/8" thick.
