Each charger is designed to deliver the correct voltage and current for its specific battery model. Using incompatible chargers can overload the cells, cause overheating, or drastically reduce battery life.
3. Charge the battery fully before using the tool for the first time
Connect the battery to the charger until the indicator light displays a full charge. A complete first charge helps the internal management system calibrate and ensures the battery reaches its intended storage and working capacity.
4. Do not interrupt the first charge cycle
Avoid removing the battery before the initial charge is complete. Interrupting the first cycle may lead to inaccurate calibration and reduce the battery’s ability to hold charge over time.
5. Allow the battery to rest before use
After removing it from the charger, let the battery sit for approximately 5 minutes. This resting period allows the internal cells to stabilize their temperature and voltage before being placed under load.
Essential Guidelines to Maximize Lithium Battery Lifespan
Lithium batteries are highly efficient and durable when used correctly. Following the recommendations below will significantly extend their operating life and protect their charging capacity.
1. Avoid deep discharges whenever possible
Lithium batteries do not need to be drained completely. Allowing the charge to drop below 20 percent repeatedly increases internal stress and accelerates aging of the cells.
2. Do not leave the battery charging for long periods after it reaches 100 percent
Although lithium batteries have internal protection circuits, prolonged overcharging generates unnecessary heat, which gradually degrades the cells.
3. Store the battery under the right conditions
If you plan to store the battery for several weeks or months:
- Keep it between 40 and 60 percent charge.
- Store it in a cool, dry environment.
- Avoid any temperature above 35°C or below 0°C.
Extreme temperatures are one of the main causes of premature battery deterioration.
4. Use the battery regularly
Lithium batteries benefit from periodic use. If the tool stays unused, the battery may enter deep sleep mode, reducing its responsiveness. Running the tool briefly every few weeks helps keep the cells active.
5. Keep battery contacts clean and free of debris
Use a dry cloth to clean the metal contacts occasionally. Dust, grease, or oxidation can interfere with energy transfer and slow down charging.
6. Allow the battery to cool before charging
Charging a hot battery causes chemical stress and increases internal resistance, reducing the number of usable cycles. If the battery warms up during use, let it cool to room temperature before attaching it to the charger.
7. Protect the battery from moisture and impacts
Water, oil, or cleaning products can damage the internal circuit board and permanently affect battery safety. Also avoid drops or strong impacts, as lithium cells are sensitive to deformation.
Torque Adjustment Instructions
Correct torque adjustment is essential to ensure safety, avoid damage to components, and improve the tool’s performance.
1. Identify the torque control system of your impact wrench
Most models offer:
- Multiple speed levels
- Torque presets
- Variable trigger pressure for fine control
Understanding these settings will help you adjust the tool accurately.
2. Choose the correct torque level for your task
Low torque: ideal for small screws, delicate materials, and assembly work where precision is important.
Medium torque: recommended for automotive tasks, household repairs, and general fastening.
High torque: used for heavy-duty applications such as loosening tight bolts, construction work, and rusted or seized fasteners.
3. Start with a lower torque setting
When working on unfamiliar materials or hardware, begin at the lowest power level. Gradually increase until the screw or bolt is tightened securely without over-tightening.
4. Avoid excessive torque
Applying too much torque can damage threads, crack components, or make future removal difficult. Use proper socket sizes and always keep the tool aligned with the fastener to prevent slipping.
5. Test torque on a sample piece when possible
If you are working on sensitive materials or new parts, test the torque setting on a spare piece before applying it to the final job.
How to Set the Correct Power Supply for Different Types of Work
1. Understand your tool’s power system
Depending on the model, your impact wrench may operate on lithium-ion battery packs or external power adapters. Most modern impact wrenches rely on rechargeable batteries, so proper battery management is essential.
2. For small or medium tasks, use a partially charged battery
For light work such as furniture assembly or general home use, a battery between 50% and 80% is sufficient. This helps preserve long-term battery health while still delivering consistent performance.
3. For heavy-duty jobs, ensure a fully charged battery
Tasks like removing wheel nuts, working on machinery, or loosening rusted bolts require maximum power output. Always start with a fully charged battery for these situations to avoid power drops during operation.
4. Avoid using the tool when the battery is below 20%
Low voltage reduces torque, causes the tool to strain, and accelerates battery wear. Recharge once the battery reaches approximately 20–30%.
5. Use the correct charger and allow full charge cycles
The original charger provides the exact voltage and current your battery requires. Using third-party chargers may lead to overheating, inconsistent power delivery, or long-term damage.
6. Keep a spare battery for uninterrupted work
If you frequently work on heavy jobs or long projects, having a second battery ensures continuous power. Alternate between batteries to maintain healthy charge cycles.
7. Store batteries properly when not in use
Keep the battery between 40% and 60% charge, away from heat, moisture, or direct sunlight. Correct storage guarantees safer and more efficient operation during future tasks.

Avoid applying sideways pressure or forcing the tool forward. Simply hold it in place and allow the impact mechanism to deliver the necessary power.
Work Cycles, Pause Time, and Usage Limits
1. Understand the tool’s work cycle
Impact wrenches are designed to operate in short, controlled bursts rather than continuous use. A typical work cycle involves applying torque for a few seconds, followed by a brief rest period. This prevents overheating and ensures consistent performance.
2. Avoid prolonged continuous operation
Using the tool nonstop for long periods can cause excess heat in the motor, gearbox, and battery. Always limit each operation to short intervals, especially when working with high torque loads or stubborn fasteners.
3. Allow proper cooling time
If the tool becomes warm during use, pause for several minutes to let it cool down naturally. Forced cooling (like placing it near fans or in cold environments) is not recommended, as rapid temperature changes may affect internal components.
4. Monitor battery temperature
Lithium batteries can heat up during demanding tasks. If the battery becomes hot, remove it and allow it to cool before charging or reinstalling. Operating or charging a hot battery reduces its lifespan and may damage internal cells.
5. Respect usage limits for heavy-duty tasks
When working on jobs that require maximum power, such as loosening tight or rusted bolts, use the tool in short bursts. Overloading the tool by holding the trigger continuously can strain both the motor and impact mechanism.
6. Alternate tasks to prevent overheating
If performing multiple high-torque operations, switch between heavy and light tasks to allow the tool and battery to recover gradually.
7. Stop immediately if you notice performance drop
A sudden decrease in torque, unusual noise, or increased vibration may indicate overheating. Pause use and allow the tool to cool before continuing.
Maintenance: Lubrication & O-Ring Care
Tool Lubrication: Importance, Frequency, and Proper Application
Proper lubrication is essential to keep your impact wrench running smoothly, extend its lifespan, and ensure consistent performance during demanding tasks. Internal components such as the hammer mechanism, bearings, and moving parts rely on adequate lubrication to reduce friction and prevent premature wear. Understanding how and when to lubricate your tool is an important part of maintaining its long-term reliability.
1. Why lubrication matters
The internal hammering system of an impact wrench generates high levels of force and rapid movement. Without proper lubrication, this friction increases significantly, which can lead to overheating, loss of power, and accelerated component wear. Regular lubrication keeps the parts moving freely and improves efficiency during operation.
2. Identify lubrication points
Most impact wrenches include designated areas where lubrication should be applied, such as the anvil, hammer mechanism, and sometimes the front housing. Always check your model’s manual to confirm the correct lubrication points and recommended grease type.
3. Use the correct lubricant
Impact wrenches require high-quality, high-temperature grease specifically designed for impact mechanisms. Using the wrong type of lubricant can break down under heavy loads or cause internal clogging. Avoid oils or lightweight greases unless explicitly recommended by the manufacturer.
4. How often to lubricate
Frequency depends on usage:
- Frequent or heavy-duty use: lubricate every few weeks or after large projects
- Moderate use: lubricate every 1–2 months
- Occasional use: lubricate every 3–6 months
If the tool begins making unusual noises, feels rough during operation, or loses efficiency, lubrication may be needed sooner.
5. Steps for proper lubrication
- Disconnect the tool from the battery before servicing
- Remove the front housing or access cover (if applicable)
- Clean dust or old grease from visible areas using a dry cloth
- Apply a small amount of recommended grease directly onto the moving parts
- Reassemble the tool securely before use
Avoid over-lubricating, as excess grease can trap dust and reduce performance.
6. Keep the anvil lightly lubricated
The anvil—the square drive where sockets attach—experiences constant friction. Apply a small layer of grease occasionally to ensure smooth socket engagement and prevent rust.
7. Watch for signs of poor lubrication
- Unusual grinding noises
- Reduced torque or slower performance
- Excessive heat during short work cycles
- Increased vibration
If any of these signs appear, stop using the tool and inspect lubrication before continuing.
8. Store the tool properly after lubrication
After servicing, store the impact wrench in a dry environment to prevent grease contamination. Keeping dust and moisture away preserves both the internal mechanism and the lubrication itself.
