FAQ:
What causes hydraulic pump cavitation?

Possible low hydraulic oil level, high oil viscosity, or restricted fluid flow.

Solution: Refill hydraulic oil, use correct viscosity oil, check and clear restricted areas.

How to charge a new battery for the first time?

After the newly purchased battery is injected with the liquid with the appropriate specific gravity, it should be placed for 6-8 hours to allow the liquid to penetrate the plates. When the temperature of the liquid drops below 30℃, it can be charged for the first time. The initial charge should be carried out in two stages. The charging current in the first stage should be lower than 1/10 (one tenth) of the rated capacity of the battery, and the time is about 25-35 hours. When the voltage of a single cell rises to 2.4 volts, the current is reduced by half and the second stage is entered, which takes about 20-30 hours. When the electrolyte emits strong bubbles and the specific gravity no longer rises, the voltage of a single cell rises to 2.6-2.75 volts and remains unchanged for 2-3 hours, it means that the battery is fully charged. During charging, the temperature of the electrolyte will rise, exceeding 40℃ in summer and 35℃ in winter. Charging should be suspended and recharged when the temperature drops below 30℃ to prevent damage to the plates and separators.

How to troubleshoot the excavator's swing system?

Swing system issues are usually related to the hydraulic motor, swing gears, or control valves. First, check the operation of the hydraulic motor, inspect the gears for wear, and ensure the control valves are working properly. Replace faulty parts as needed.

How to deal with hydraulic pump overheating?

The way to deal with overheating is to check the hydraulic oil level, clean or replace the filter, check the cooling system and adjust the system load.
