Common symptoms
- Saw dead with charged pack
- The chain travels around the bar but only rubs the wood, produces almost no chips, and will not enter the cut.
- The saw chain leaves the guide-bar groove, hangs from the bar, or comes off the drive sprocket.
- Chain moves but does not cut
- The saw cuts slowly, makes fine dust instead of chips, chatters in the kerf, or must be pushed hard despite judging sharpness.
- The reservoir contains oil but the chain stays dry, the primer gives no visible result, or the bar oil path remains dry.
- The lock-off or trigger will not move freely, does not return, responds intermittently, or the motor continues after the trigger is released.
- The guide bar steers sideways in the cut or the kerf curves even though the workpiece is supported and the saw is held square.
