How to Fix the Problem

If you have a JLg warning light that is on, there are a few things that you can do to try and fix the problem. The first thing you should do is check the oil level in the engine. If the oil level is low, you must add more oil to the engine. If the oil level is acceptable, you should check the air filter. If the air filter is dirty, you must replace it with a new one. Lastly, if none of these things fix the problem, you will need to take your car to a mechanic and have them look at it.

JLG requires that all employees wear a full body harness with an attached lanyard or lanyard anchorage point when operating JLG scissor lifts or vertical mast products that lack a 30-in. (76 cm) maximum length limit, which is not required by either ANSI, CSA, or OSHA. Unexpected events in the workplace are infrequent, but as these incidents happen more often in lift accidents, JLG strongly recommends using this equipment during all types of operations.

What are illuminated warning lights?

Starting a car triggers dashboard warning lights to briefly illuminate as the vehicle warms up and confirms all systems are functioning correctly. Should something be amiss, these lights will remain decorated so the car can communicate that attention is needed.
