Changing the Oil
1. Start the engine and let it run five minutes. This
warms the oil so it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to ensure that the oil
drains completely.
3. Lower the boom and set the parking brake.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Place a pan below the drain hose. Rotate the oil drain
valve to allow oil to drain (Figure 36).

On model 22974, the oil drain is on the opposite side of
the machine.
