常见症状

The battery will not slide fully into the tool, click into place, stay latched, or release normally.

查看详情

The chain travels around the bar but only rubs the wood, produces almost no chips, and will not enter the cut.

查看详情

The saw chain leaves the guide-bar groove, hangs from the bar, or comes off the drive sprocket.

查看详情

Bar oil forms a fresh puddle, runs from the cap, or appears from the body while the saw is idle or stored.

查看详情

The cap will not close, the primer is split or stuck, or the oil-level indicator is cracked, clouded, or leaking.

查看详情

The saw cuts slowly, makes fine dust instead of chips, chatters in the kerf, or must be pushed hard despite judging sharpness.

查看详情

The lock-off or trigger will not move freely, does not return, responds intermittently, or the motor continues after the trigger is released.

查看详情

The reservoir contains oil but the chain stays dry, the primer gives no visible result, or the bar oil path remains dry.

查看详情

Saw dead with charged pack

查看详情

The saw makes new grinding, clacking, rattling, or strong vibration during no-load running or cutting.

查看详情

After chain or bar work, the cover will not sit flush, the bar will not align, or the locking knob cannot begin correctly.

查看详情

The bar is bent or cracked, chain links or cutters are broken, or the guide-bar scabbard is split, missing, or will not stay on.

查看详情

Motor runs, chain does not

查看详情

The guide bar steers sideways in the cut or the kerf curves even though the workpiece is supported and the saw is held square.

查看详情

Chain moves but does not cut

查看详情

The guide bar cannot be withdrawn from the kerf, the chain is trapped, or the workpiece closes on the saw.

查看详情

The lithium battery or charger shows abnormal heat, swelling, cracking, electrolyte, hissing, odor, sparks, or smoke.

查看详情

The chain hangs below the guide bar, can be pulled too far from the rail, or becomes loose again after adjustment.

查看详情

Liquid entered the tool, the housing emits smoke or sparks, plastic melts, a burning odor appears, or wiring or contacts are exposed.

查看详情

The chain is hard to pull around the bar, the bar becomes unusually hot, or smoke appears without an electrical odor.

查看详情

The front hand guard, front or rear handle, main housing, ribbed bumper, fastener, battery well, or another external part is cracked, loose, or missing.

查看详情

A tool-free knob is frozen, cross-threaded, spins without effect, will not clamp the bar, or cannot hold the set tension.

查看详情

The motor can be heard, but the chain remains stationary or only twitches while the trigger is held.
