Abstract
A handheld cutting tool includes a motor, a driven gear coupled to the motor and a sprocket coupled for co-rotation with the driven gear, a housing, a guide bar extending from the housing, a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar, and a battery pack removably coupled to the housing, the battery pack including a foot portion defining a base plane. The center of gravity of the handheld cutting tool is located above the foot portion when the handheld cutting tool is stood upright on the foot portion, thus permitting the handheld cutting tool to balance only on the foot portion of the battery pack.

A handheld cutting tool comprising:
- a motor;
- a driven gear coupled to the motor and a sprocket coupled for co-rotation with the driven gear;
- a housing;
- a guide bar extending from the housing;
- a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar;
- and
- a battery pack removably coupled to the housing, the battery pack including a foot portion defining a base plane;
- wherein a center of gravity of the handheld cutting tool is located above the foot portion when the handheld cutting tool is stood upright on the foot portion, thus permitting the handheld cutting tool to balance only on the foot portion of the battery pack.
A handheld cutting tool comprising:
- a motor;
- a driven gear coupled to the motor for receiving torque therefrom and a sprocket coupled for co-rotation with the driven gear;
- a housing including a motor housing portion in which the motor is located, a drive housing portion in which the driven gear and sprocket are located, and a handle portion extending from one of the motor housing portion or the drive housing portion;
- a handle guard extending from the handle portion to one of the drive housing portion or the motor housing portion, wherein the handle guard includes a support face that defines a plane relative to the housing;
- a guide bar extending from the drive housing portion in a direction transverse to the plane;
- a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar;
- and
- a battery pack removably coupled to a bottom part of the handle portion, the battery pack including a stem and a foot extending transversely from the stem,
- wherein the support face of the handle guard is configured to support the handheld cutting tool in a horizontal position, and
- wherein the foot of the battery pack is configured to support the handheld cutting tool in an upright position.
A handheld cutting tool comprising:
- a motor;
- a driven gear coupled to the motor and a sprocket coupled for co-rotation with the driven gear;
- a housing;
- a guide bar extending from the housing;
- a chain supported on the guide bar and engaged with the sprocket such that rotation of the sprocket moves the chain along the guide bar;
- a battery pack removably coupled to the housing, the battery pack including a foot portion;
