4.The tool must be allowed to recoil away from the work piece.

To continue operation in a separate location, move the tool along the work piece, repeating steps 2 through 4 as required.

To use the tool to drive nails in this actuation mode the work contact element and trigger can be actuated in any order.

6.As soon as the desired number of nails has been driven, remove finger from trigger.

Remove finger from the trigger when not ! WARNING driving nails. Always carry the tool by the

handle only. Removing your finger from the trigger when not operating the tool reduces the risk of unintentionally firing a nail and injuring yourself or someone else.

The tool must be allowed to recoil away ! WARNING from the work piece. Do not drive a nail

on top of another nail. If the tool is not moved before the trigger is pulled again a second nail will be driven on top of the previously driven nail. This could cause the nail to be deflected or the tool to react in an unexpected manner.
