When a hydraulic power unit breaks down, only a trained professional should conduct repairs.
However, routine preventative maintenance is not quite so demanding a task. As long as you follow
manufacturer's instructions for maintenance, you should be able to conduct preventative maintenance
on your own without risking the safety of those using the power unit.
Lubricating electric motors
Proper lubrication is essential for maintaining the performance and longevity of electric motors.
To ensure effective lubrication, it is recommended to follow the manufacturer's guidelines provided in
the motor's manual or by contacting the manufacturer directly. These guidelines will outline the specific
lubrication requirements and frequency for your particular motor model. Adhering to the recommended
lubrication practices is crucial to keep the motor in optimal condition.
Cleaning or replacing filters
The power unit of your electric motor may be equipped with a filter that indicates
when it requires cleaning or replacement. It is important to check this indicator immediately
after starting up the system to address any maintenance needs before operating the power unit.
If your power unit does not have an indicator, refer to its manual to determine how often you should
clean or replace the filter. When replacing a filter, ensure that you use a similar type as specified
by the manufacturer. If cleaning is required, carefully follow the provided instructions
to thoroughly remove all contaminants before reinstalling.
Cleaning suction strainers
Suction strainers in your machine typically require cleaning after approximately 10 hours of initial use
and then every 100 hours thereafter. However, it is important to consult
your specific manufacturer's guidelines for precise cleaning intervals.
Maintaining oil level in reservoirs
Regularly checking and maintaining proper oil levels in reservoirs are crucial for optimal motor performance.
Periodically inspecting oil levels, especially during initial usage of the power unit, ensures they do not
fall below recommended thresholds. Ideally, check reservoir levels after every 100 hours of operation.
Changing the oil
The oil in your hydraulic power unit should be changed based on manufacturer requirements.
Typically, oil changes are needed somewhere between 1,000 and 2,000 hours of use; however,
this can vary depending on factors such as environmental conditions and application demands placed on the power unit.
Checking the oil
It is important to monitor oil temperature during operation to ensure it does not run too hot.
Signs that indicate overheating include significantly darker color compared to fresh oil and a burnt smell.
