ETS82 Rock Drill FAQs & Troubleshooting
Q1: Is the ETS82 faster than the YT28?
A: Yes. With an impact frequency of ≥39 Hz and ≥78J impact energy, the ETS82 is designed for ultra-fast penetration in tunneling projects, typically providing a 15-20% boost in advance rates over standard models.
Q2: What is the ideal air pressure for the ETS82?
A: To achieve maximum 78J impact, the ETS82 requires a stable 0.63 MPa (90 PSI). If pressure drops to 0.4 MPa, the impact energy falls significantly to 50J, reducing drilling speed.
Q3: Can this machine be used for vertical drilling?
A: The ETS82 is a pusher-leg drill optimized for horizontal and inclined drilling. For vertical downward drilling, we recommend using a handheld sinker drill; for vertical upward, a stoper drill is best.
Q4: Why is my ETS82 penetrating slowly despite high air pressure?
A: Check the pusher leg thrust and drill bit sharpness. If the FT160A air-leg isn't pushing hard enough (due to worn YX seals), impact energy is wasted as the drill bounces off the rock face.
Q5: Are the internal spare parts interchangeable with other brands?
A: Yes. Our ETS82 components are manufactured to strict global technical dimensions. Major parts like the ETS82-12 Piston and YT29-5 Valve are highly compatible with standard pneumatic setups.
Q6: Why is consistent lubrication critical for the ETS82?
A: Due to its high frequency (39Hz), the piston generates significant heat. Using the FY250 lubricator with standard rock drill oil is essential to prevent internal component seizure and maintain consistent impact force.
