Makita XGT 40V max Impact Wrench 4 Speed 1/2in (Bare Tool) - GWT04Z

Makita XGT 40V max Impact Wrench 4 Speed 1/2in (Bare Tool) - GWT04Z 

The Makita XGT brushless cordless impact wrench kit with a 1/2 Inch square drive is designed to use for automotive, installation and fabrication industries for getting enhanced fastening control. This impact wrench is powered by a Makita-built brushless motor that delivers 465 ft-lb of nut-busting torque and 260 ft-lb of fastening torque that aids in heavy-duty applications. Four operating speeds can be selected with the help of a power selection switch that facilitates in a wide range of applications. Three forward and three reverse rotation auto-stop modes are provided increases the tool efficiency when the fastener loosens the grip. Full speed mode mechanism minimizes the trigger pull to gain optimum operating speed. Extreme protection technology prevents the accumulation of water and dust on the tool even in harsh conditions. Reinforced construction of the gear endures wear and tear in jobsites. The XGT technology makes use of 40 Volt Lithium batteries to produce optimum power in high demand applications. Wrench comes with a friction ring anvil.

Maintenance Tips

1. Clean tool regularly – wipe the exterior and keep the ventilation openings clear of dust/debris to prevent overheating.

2. Protect battery contacts – before installation, wipe both tool and battery terminals dry to ensure strong power transfer and prevent corrosion.

3. Check external fasteners – periodically tighten screws/bolts that may loosen from vibration to maintain structural integrity.

4. Use XPT technology properly – although built with dust/water resistance, avoid exposure to heavy water jets or immersion to protect internal electronics.

5. Inspect drive and anvil – check the 1/2″ anvil and friction ring area for wear and remove debris that can affect socket seating.

6. Remove battery before service – always take out the battery before cleaning, adjusting, or storing the tool to avoid accidental starts.

7. Store dry & cool – keep tool and batteries in a dry, temperature‑stable location to prolong electronics and battery life.

8. Use genuine Makita batteries/chargers – only official XGT batteries and chargers help maintain performance and warranty coverage.
