Makita DA391D Problems and Solutions

some common issues and problems with the Makita DA391D and their solutions:

Issue: The impact wrench doesn't seem to be working. Solution: Check the battery to make sure it is charged. If the battery is charged, try a different battery to rule out a problem with the battery. If the impact wrench still doesn't work, check the air hose to make sure it is not kinked or damaged. If the air hose is okay, then the impact wrench may need to be serviced.

Issue: The impact wrench is making a strange noise. Solution: This could be a sign of a problem with the impact wrench. If the noise is loud or unusual, stop using the impact wrench and take it to a qualified technician for inspection.

Issue: The impact wrench is not generating enough torque. Solution: This could be due to a number of factors, including the wrong size impact socket, a dirty or clogged air filter, or a problem with the impact wrench itself. Check the impact socket to make sure it is the correct size for the fastener you are trying to loosen. If the impact socket is the correct size, then clean or replace the air filter. If the air filter is clean and the impact wrench is still not generating enough torque, then the impact wrench may need to be serviced.

Issue: The impact wrench is overheating. Solution: This is usually caused by using the impact wrench for too long at high speeds. Allow the impact wrench to cool down before using it again. If the impact wrench continues to overheat, then it may need to be serviced.

Issue: The impact wrench is leaking air. Solution: This is usually caused by a damaged air hose or a faulty o-ring. Inspect the air hose for damage and replace it if necessary. If the air hose is not damaged, then replace the o-ring.
