SLOW DOWN SPEED FOR SAFETY REASONS

Mr. Anderson

You can slow down the speed of the Yale MPB040-E using the following methods:

1. Regenerative (Neutral) Braking – Return the speed/direction control to the NEUTRAL position. This applies a retarding force to the drive wheel through the traction motor, allowing the unit to slow down gradually.

2. Controlled Plugging – Reverse the speed/direction control while traveling. This causes the unit to slow to a stop. Ensure you return the control to the NEUTRAL position to remain stopped.

3. Parking Brake – The parking brake is applied when the control handle arm is moved to the BRAKE position.

These methods help control speed effectively for safety.

Is there anything I can do to make my unit just go slow instead of fast and slow ? Have older and younger people using this unit. THANK YOU
