What to Do When the Electric Wrench Has Low Power?
3 Answers
Consider whether the battery is low on power. First, fully charge it before use. If it still feels underpowered after a full charge, use WD-40, a universal rust remover that can be applied from satellites down to screws.
Recently, I was troubled by the weak power of my electric wrench while working on my car. At first, I thought the screws were too tight, but after several attempts, it remained just as weak. I checked the battery and found that the old battery couldn't hold a charge. After replacing it with a new lithium battery, the power improved significantly. Later, I realized that frequent heavy use without timely charging might have caused the battery to degrade. The gear part also needs attention—adding some lubricant can reduce friction and make the motor run more smoothly. If the problem persists, the motor might be burnt out, and it's best to seek professional repair. Don't overlook such small issues; maintaining your tools well can greatly improve efficiency and save time.
As a frequent user of power tools, when encountering weak torque from an electric wrench, I usually start troubleshooting from the simplest aspects. Insufficient battery charge is the most common issue—try using a fully charged battery first. If the problem persists, check the voltmeter to ensure stable output. Loose or dirty connectors can also affect power transmission; clean the contact points with a damp cloth. Motor overload or inadequate cooling may cause power loss—avoid prolonged continuous operation and allow the tool to rest periodically. When necessary, upgrade to a high-torque model to prevent overworking underpowered tools. Always prioritize safety—never force an underpowered tool to avoid accidents.
