Trigger activated tools having activation lockouts

A trigger activated tool, comprising:

• a handle portion;
• an activatable device including a power source;
• an activation trigger depending from the handle portion, the activation trigger being configured for movement between a non-activated position in which the power source is not in communication with the activatable device and an activated position in which the power source is in communication with the activatable device;
• a drain trigger depending from the handle portion, the drain trigger being movable between a normal position in which hydraulic pressure is maintained in the activatable device and a drain position in which the hydraulic pressure is relieved from the activatable device;
• and
• a guard depending from the handle portion, the guard pivots about a pivot point on the handle between a guarded position and an un-guarded position,
• wherein the guard, when in the guarded position, is close enough to the activation trigger to not allow the activation trigger to be moved to the activated position, but, when in the un-guarded position, provides sufficient clearance between the guard and the activation trigger to allow the activation trigger to be moved to the activated position.
