Frequently Asked Questions

What does the master warning light mean on my Bobcat Telehandler 763?

It signals a critical fault, such as low oil pressure or overheating, and requires immediate engine shutdown to prevent damage.

Why is the hydraulic oil light amber and flashing?

On the 763, that indicates high hydraulic temperature or low fluid level; reduce load and allow system to cool.

How often should I service the 763 based on the hour meter?

Refer to the operator's manual; typically every 100 hours for engine oil and filter, with more extensive service at 500 hours.

Can I operate the 763 with the differential lock light on?

Only on soft surfaces; driving on pavement with diff lock engaged can damage the driveline.

What should I do if the water in fuel light comes on?

Drain the fuel/water separator located on the engine side of the 763 to prevent injector damage.

Why does the seat belt light stay on after buckling?

The buckle switch may be faulty or debris trapped; clean the buckle area or have the switch inspected.
