5. Symptoms of Pump Wear or Failure
Recognizing early signs of pump wear can save time and money, allowing for timely intervention before more serious damage occurs:
Increased effort required for cab tilting
Leaks or loss of hydraulic fluid
Inconsistent or jerky lifting motion
Pump unable to maintain pressure or hold the cab in position
Audible noise or vibration when operating the pump
Timely inspection and maintenance can prevent these issues from leading to costly downtime or safety incidents.
6. Maintenance and Service Practices
To ensure long service life and reliability:
Check fluid levels periodically and top up as required using manufacturer-recommended hydraulic oil.
