1.8 Movement without Drive Power
In the unlikely event of an emergency situation where robot power is either not possible or unwanted, the
robot joint can be forced to move in two ways:
1. Forced manual drive: By pushing or pulling the robot arm, it can force the joint to rotate. The brake of
each joint has a friction clutch. When the joint is subjected to a torque greater than the friction torque of the
friction clutch, the joint rotates.
2. Manual brake release: Remove the joint cover by removing the screws (four for big joints and three for
small joints) that fix it. Press the plunger on the small electromagnet (shown below) to release the brake.

Warnings:
1. Moving the robot arm manually is intended for urgent emergencies only and might damage the joints.
2. If the brake is released manually, gravitational pull can cause the robot arm to fall. Always support the
robot arm, tool and work item when releasing the brake.
1.9 Precautions for Transportation and Handling
Transport the robot in the original packaging. Save the packaging material in a dry place; you may need to
pack down and move the robot later on.
Lift both tubes of the robot arm at the same time when moving it from the packaging to the installation
place. Hold the robot in place until all mounting bolts are securely tightened at the base of the robot.
Cautions:
1. Make sure not to overload your back or other body parts when the equipment is lifted. Use proper lifting
equipment. All regional and national guidelines for lifting shall be followed. JAKA cannot be held responsible for
any damage caused by transportation of the equipment.
2. Make sure to follow the installation instructions when installing the robot.
