is a combined hammer designed for both high-speed drilling and powerful chiseling. Power Input: 900 Watts.

Drilling Range: 12 mm to 32 mm with standard hammer bits; up to 90 mm with core bits.

Impact Energy: 6.0 Joules at 100% power (adjustable to 3.0 Joules for delicate work). Weight: 5.9 kg (approx. 13 lbs).

Features: Two speeds, electronic switch for precise starting, and a built-in service indicator light. Operating Instructions: Best Practices

According to the Hilti TE 55 Manual, following these steps ensures both safety and tool longevity:

Switching Modes: Use the indicator to select between hammer drilling (percussion + rotation) and chiseling only (percussion). Always move the selector upward to unlock it before switching between modes.

Speed Selection: Use the 1st speed (lower RPM) for large-diameter drilling and the 2nd speed (higher RPM) for standard hammer drilling in masonry and concrete.

Dust Prevention: The tool features a dust-tight tool holder, but using an external dust removal system (like the TE DRS-Y) is recommended to protect the internal motor components from abrasive concrete dust. Maintenance & Troubleshooting

is built for longevity, but its internal components require periodic attention to maintain its "indestructible" reputation. 1. The Service Light (Red Light)

If the red service indicator light turns on, the carbon brushes are worn out and must be replaced. The tool includes a safety pin that automatically shuts down the motor to prevent damage to the armature once the brushes reach their wear limit. The Hilti TE 55 is a versatile SDS

Fix: Replace with genuine Hilti Replacement Brushes to ensure the service light resets and the tool functions safely. 2. Lubrication and Sealing

uses permanent lubrication, but during a deep service, it is critical to replace the O-rings and apply fresh grease to the piston, cylinder, and gears. Hardened concrete dust can often jam the speed selector or airflow; regularly blowing out the vents with compressed air can prevent overheating. 3. Tool Holder Repairs

If the SDS Max chuck fails to hold a bit or chisel, the tool holder bush may need servicing. This typically involves replacing the internal steel balls and springs that lock the bit in place. YouTube·CheapskateProjectshttps://www.youtube.com Fixing Hilti TE 55 hammer drill
