    A weak striking force in your Trojan Tools can stem from several causes. The engine rotation speed might be too low, requiring adjustment. The gas pressure in either the N2 Chamber or Accumulator could be insufficient, necessitating a check and recharge. Additionally, the pressure might be set incorrectly, or the overflow valve could be broken, so check and regulate it. The chisel could be damaged, requiring grinding of the damaged chisel or bushing. Finally, the hydraulic oil level might be low or the oil might be dirty; in that case, check, add, or change the oil.

    If your Trojan Tools isn't striking, several factors could be at play. The overflow valve pressure might be incorrect, requiring adjustment to the proper level. Alternatively, the gas pressure in the N2 chamber may be too high, also needing regulation. Oil leakage into the chamber is another possibility, which would necessitate replacing the oil seal. Lastly, damage to the cylinder, piston, or valves could be the cause, in which case, repair the surface with abrasive paper.

    An unsteady striking action in your Trojan Tools can arise from a few potential issues. First, the gas pressure in the N2 chamber might be too high, requiring adjustment to the correct pressure. Second, the pressure of the overflow valve might be too low, which also needs to be regulated to the proper level. Damage to the chisel or bush is another possibility, and you should grind the damaged part to repair it. Lastly, the cylinder, piston, or valves could be damaged, needing surface repair with abrasive paper.

    Nitrogen leaks in your Trojan Tools can occur due to several reasons. Here's how to address them: * If the inlet is leaking, replace the bushing O seal ring. * If the air valve is leaking, replace the valve O seal ring. * If the N2 chamber is leaking, fasten the through bolts. * If you dismantle the oil return hose and air bubbles exist in the oil, it means the air seal is damaged, so replace the seal.
