1. Position the device on a flat surface.
2. Locate the oil filler cap, often found at the top of the pump unit.
3. Remove the cap and check the oil level using a dipstick, if available.
4. The oil should be within the marked range. If the oil is low, top it up with the recommended type of oil.
Changing the Pump Oil
To change the oil, follow these steps:
1. Ensure the unit is off and cooled down.
2. Place a container underneath the oil drain plug to collect used oil.
3. Remove the drain plug and let the oil completely drain out.
4. Replace the drain plug securely.
5. Refill the pump with fresh oil until it reaches the proper level.
6. Replace the oil filler cap.
Always use the oil specified in your manual for optimal performance. Neglecting pump lubrication can lead to overheating and damage, resulting in costly repairs.
