Metabo HPT Demolition Hammer, 70 Pound, 51.6 Ft-Lbs (70J) of Impact Energy, 1-1/8 In. Hex Shank  - H90SG

The 1-1/8 Inch Hex Demolition Hammer (H90SG) makes improvements on previous models with greater power, increased performance, lower vibration and a universal tool retainer. The 15 amp motor powers an improved hammering mechanism, which more efficiently transfers energy to the bit, improving demolition performance. A new vibration absorbing main handle produces low full-load vibration, resulting in less user fatigue and greater productivity. This hammer employs a sealed grease system and auto-stop brushes for minimal maintenance and durability.

Maintenance Tips

• Clean After Use: Wipe down the tool and use compressed air around the bit holder and vents to remove dust and debris that can build up during demolition work.
• Inspect & Tighten Fasteners: Regularly check and tighten housing screws and handles — heavy vibration can loosen them over time.
• Maintain the Bit Retainer: Ensure the 1‑1/8 in. hex bit and retainer are clean and secure before each use to prevent slippage and reduce wear.
• Monitor Brushes & Sealed Grease System: The H90SG uses a sealed grease system and auto‑stop brushes for durability; if brushes wear (indicated in manual), replace with genuine parts per instructions.
• Avoid Overheating: Operate within the intended duty cycle — running continuously at full load generates heat and stresses internal components.
• Power Cord Care: Check the power cord for cuts, kinks, or frays before each use — damaged cords can compromise performance and safety.
• Control Vibration: Use the built‑in User Vibration Protection (UVP) properly and take breaks to reduce fatigue and stress on tool internals.
• Lubricate Moving Contact Points: After heavy use, lightly lubricate contact areas (as outlined in the manual) to prevent binding and wear.
