Frequently Asked Questions
What should I do if the hydraulic oil light comes on during operation?
Stop the U17, check the hydraulic oil level, and inspect for leaks around hoses and connections before resuming work.
Why does the glow plug light stay on after starting?
If the glow plug light remains lit, it could indicate a fault with the preheat system; have the glow plugs and relay checked.
How often should I service the air filter on my U17?
Check and clean the air filter every 50 hours or more frequently in dusty environments; replace if heavily clogged.
Can I operate the U17 if the fuel filter light is on?
Avoid operating until the filter is drained or replaced, as contaminated fuel can cause poor performance or engine damage.
What does it mean if the master warning light appears?
This signals a major fault; check the display for further details and address the issue before continuing operation.
