Impact tool

An impact tool comprising:

• a housing having a handle portion defining a first axis;
• a motor supported by the housing and defining a motor axis;
• a rotary impact mechanism arranged on a second axis that is perpendicular to the first axis, the rotary impact mechanism configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece, the rotary impact mechanism including
• a cylinder partially defining a chamber containing a hydraulic fluid,
• an anvil positioned at least partially within the chamber, and
• a hammer for imparting the consecutive rotational impacts upon the anvil, the hammer configured to translate within the cylinder along the second axis in a first direction, towards the anvil, and a second direction, away from the anvil;
• and
• a gear train that receives torque from the motor and includes a rotational input that transfers torque to the rotary impact mechanism,
• wherein the hydraulic fluid is at a first pressure on a first side of the hammer and at a second pressure greater than the first pressure on a second side of the hammer opposite the first side when the hammer translates away from the anvil.
