Frequently Asked Questions
What should I do if the B20T-7 shows the BDI battery discharge warning?
Finish your current task and return the forklift to the charging station before the battery is fully depleted.
Why does the overload indicator come on even with a seemingly light load?
Ensure the load is positioned correctly on the forks and that the weight does not exceed the B20T-7's rated capacity; faulty sensors may also trigger the warning.
How often does the B20T-7 require service based on the hour meter?
Service intervals are typically every 500 hours, but always refer to your Doosan maintenance schedule for specifics.
Can I operate the B20T-7 if the air filter warning is on?
Operation is possible but not recommended; a clogged air filter can reduce performance and should be cleaned or replaced promptly.
Is it safe to drive with the parking brake light on?
No; driving with the parking brake engaged can damage the brake system—release it before moving.
