  Several factors could prevent your Stihl Power Tool garden shears from starting. It could be due to a lack of electrical contact between the shears and the battery. Try removing and reinserting the battery, and visually inspect the electrical contacts. A low battery charge or a battery that's too hot or cold can also be the cause. Let the battery warm up or cool down gradually at ambient temperatures of about 50 °F to 68 °F (10 °C to 20 °C). There may also be a malfunction in the battery or garden shears, or the shears may be too hot; in this case, allow the garden shears to cool down. If problems persist, the battery or the garden shears have a malfunction and must be replaced.

  Your Stihl Power Tool garden shears might not start due to several reasons. There may be no electrical contact between the shears and the battery. To resolve this, remove the battery, visually inspect the electrical contacts, and then reinsert the battery. Another cause could be a low battery charge, in which case you should charge the battery. The battery might also be too hot or too cold; allow it to warm up or cool down at ambient temperatures of about 50 °F to 68 °F (10 °C to 20 °C). A malfunction in the battery or garden shears could also be the reason. Try removing and reinserting the battery and the cutting attachment, then switch on the garden shears.
