Symptoms

Saw dead with charged pack
Motor runs, chain does not
Chain moves but does not cut
The chain is hard to pull around the bar, the bar becomes unusually hot, or smoke appears without an electrical odor.
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.
The lithium battery or charger shows abnormal heat, swelling, cracking, electrolyte, hissing, odor, sparks, or smoke.
The motor can be heard, but the chain remains stationary or only twitches while the trigger is held.
The guide bar steers sideways in the cut or the kerf curves even though the workpiece is supported and the saw is held square.
After chain or bar work, the cover will not sit flush, the bar will not align, or the locking knob cannot begin correctly.
The reservoir contains oil but the chain stays dry, the primer gives no visible result, or the bar oil path remains dry.
A tool-free knob is frozen, cross-threaded, spins without effect, will not clamp the bar, or cannot hold the set tension.
Liquid entered the tool, the housing emits smoke or sparks, plastic melts, a burning odor appears, or wiring or contacts are exposed.
The saw cuts slowly, makes fine dust instead of chips, chatters in the kerf, or must be pushed hard despite judging sharpness.
The chain hangs below the guide bar, can be pulled too far from the rail, or becomes loose again after adjustment.
battery उपकरण में पूरी तरह से नहीं फिसलता, जगह पर क्लिक नहीं करता, लॉक नहीं रहता, या सामान्य रूप से रिलीज़ नहीं होता।
चेन बार के चारों ओर घूमता है लेकिन केवल लकड़ी को रगड़ता है, लगभग कोई चिप्स नहीं बनाता, और कट में प्रवेश नहीं करता।
With no fastener load, the bare or correctly fitted output sounds harsh, binds, knocks, or shakes abnormally.
आरी पूरी तरह से बंद है - कोई वर्कलाइट और कोई Motor प्रतिक्रिया नहीं
The motor can be heard, but the front output remains still in both directions with the bit removed.
A straight bit traces a visible circle at no load instead of rotating on a stable centerline.
