First, check whether the machine has been regularly maintained and if the hydraulic oil has been replaced on time. Inspect for blockages in the hydraulic lines, check system pressure at idle, and examine the return oil filter for clogging.
The excavator drill conversion supports various rock drill combinations to meet different drilling needs.
It is recommended not to let the drill idle for long periods or repeatedly under low RPM, as this can cause fuel mixture gases to enter the crankcase, diluting the engine oil.
Low cost: Provides the same drilling capabilities as a rock drill platform without affecting the excavator’s functionality. Additionally, due to the excavator’s superior climbing ability and drill angle adjustments, it is more flexible than traditional rock drill platforms. It costs only 1/10 of a hydraulic rock drill platform, even less than pneumatic rock drill platforms.
Metal debris, such as iron filings, is a major contaminant. These may be caused by abrasion from the high-speed rotation of the pump, or by wear on components such as bearings and chambers. Abrasions from the hydraulic valve spool and cylinder movement can also generate debris, but this is usually not a concern in the short term.
If your excavator drill conversion, DTH drill conversion, or hydraulic drill conversion equipment is new, it will generate significant metal debris during the break-in period. When changing the oil, ensure to completely empty the hydraulic oil from the tank, wipe the tank clean with cotton cloths, and then add new oil. If not fully emptied, iron filings may remain in the tank, contaminating the new oil and causing it to turn black.
For replacing the power belt, first loosen the belt and set the manual valve on the manual hydraulic pump to the "loose belt" position.
Hydraulic oil replacement must be completed on the same day. When replacing the hydraulic oil in excavator drill conversions, DTH drill conversions, or hydraulic drill excavators, it should be done on the same day to avoid overnight delays. Lower temperatures at night cause moisture in the air to form vapor, which can condense into water droplets or frost. If it enters the system, it can cause rusting of metal parts.
If a fault occurs during operation, first check for electrical issues, including the excavator’s CPU, high/low pressure sensors, solenoid valves, and wiring.
