Q: Where is the Hyster forklift hydraulic fluid location? 

A: Find the vented fill cap and fill gauge on its side that determines hydraulic fluid levels.

Q: How often should you change oil in a forklift? 

A: Every 250 hours, give or take. 

Q: What fluid levels need to be checked before using the forklift?

A: Fuel, oil coolant, brake fluid, and hydraulic.
