A method of transitioning a dual operating mode hand tool for dispensing plastic fasteners between a first operating mode and a second operating mode comprising the steps of:
- providing a hand tool having a casing with a barrel portion, a
- handle portion, and a channel a portion, said casing having a needle assembly opening at a front end of the barrel portion, a hollow needle, a needle assembly, a trigger, a locking switch, and an anvil, said anvil having a front portion and a rear portion;
- rotating said front portion of said anvil from a first operating mode position near the front of said barrel portion to a second operating mode position near said channel portion;
- depressing a safety button wherein the safety button includes an elongated portion and a safety button face and wherein a first tooth and a second tooth extend from a shelf that projects from the elongated portion;
- moving said safety switch to an unlocked position;
- actuating said trigger to advance said needle assembly from a first operating mode position at a rear end of said barrel portion to a second operating mode position at the front end of said barrel portion;
- and
- releasing said safety switch to lock said needle assembly in said second operating mode position.
