The first and second side plates (400, 410) each face other and extend away from a housing (110) to a nose. The core (420) is disposed between the first side plate (400) and the second side plate (410). The tension indicator (240) is provided at the core (420) and is visible at at least one of the first side plate 10 (400) or the second side plate (410). The tension indicator (240) is configured to indicate a chain tension based on a position of the guide bar (120).

A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes first and second side plates (200, 210) and a laminate core (260). The guide bar (120) is configured to deliver water through at least a portion of the guide bar (120). The first and second side plates (200, 210) each face other and extend away from a housing (110) to a nose. The laminate core (260) is disposed between the first side plate (200) and the second side plate (210). The laminate core (260) includes channels (270) for delivery of the water to nozzles (300, 310, 320) formed along a periphery of the guide bar (120). A glue layer (280) is provided to affix the laminate core (260) to the first side plate (200) and second side plate (210), respectively. The glue layer (280) forms the nozzles (300, 310, 320) in combination with the laminate core (260).

The disclosure provides a chain saw, which includes: a case; a working component extending out of the case, the working component having a cutting element and a guide plate supporting the cutting element; a power drive device, including a motor positioned in the case, the motor drives the cutting element to move around the guide plate; a switch trigger, arranged on the case and starts the motor; and a lubricating component, arranged in the case and provides oil for the cutting element. The chain saw includes a lock knob capable of locking and releasing the switch trigger. The lubricating component includes an oil bubble arranged in the case and is close to the lock knob. The lock knob compresses the oil bubble to perform an oil discharging operation in a process from locking the switch trigger to releasing the switch trigger. The lubricating component delivers oil to the cutting element.
