5 Maintenance and Repair
Maintenance and repairing must be performed in compliance with all safety instructions in this manual.
Repairing must be performed by an authorized system integrator or JAKA staff.
Parts returned to JAKA should be returned as specified in the Service Manual.。
5.1 Safety Instructions
After maintenance and repair, product must be checked to ensure the required safety level.The valid
national or regional work safety regulations must be observed for this check.The correct functioning of all safety
functions shall also be tested.
The purpose of maintenance and repairing is to ensure that the system is kept operational or, in the event
of a fault, to return the system to an operational state. Repairing includes troubleshooting in addition to the
actual repair itself.
The following safety procedures and warnings must be observed during the operation of the robot or
electrical cabinet:
DANGER:
1. Do not change anything in the safety configuration of the software. If any
safety parameter is changed, the complete robot system shall be considered
as a new system, which means that the overall safety approval process,
including risk assessment, shall be updated accordingly.
2. Replace faulty components using new components with the same article
numbers or equivalent components approved by JAKA for this purpose.
3. Reactivate any deactivated safety measures immediately after the work
is completed.
4. Document all repairs and save this documentation in the technical file
associated with the complete robot system.。
DANGER:
1. Remove the main input cable from the bottom of the electrical cabinet to
ensure that it is completely powered off. Disconnected any other source of
energy connected to the robot arm or control box. Take necessary precautions
to prevent other persons from powering on the system during the repair
period.
2. Check the earth connection before re-opening the system.
3. Observe ESD regulations during the disassembly of the parts of the
robot or electrical cabinet.
4. Avoid disassembling the power supply inside the electrical cabinet. High
voltages can be present inside these power supplies for several hours after
the electrical cabinet has been switched off.
5. Prevent water and dust from entering the robot or electrical cabinet.

5.2 Overhaul Project and Cycle
In order for the robot to maintain high performance for a long time, a maintenance check must be carried
out. The person in charge of overhaul must prepare an overhaul plan and carry out an inspection. Please refer
to the table below for overhaul items.
In addition, overhauls are required every 20,000 hours of operation time or every 4 years. If you are not
clear about the maintenance processes, please contact our service department.

4 Overhaul
(P.S.) Use a soft cloth to remove dusts when cleaning. Do not blow off dust with equipment such as air
blowers. Wind pressure will cause the dusts to enter the inside of the fan and the blades rotate at a speed
exceeding the rated speed, which may cause the fan to malfunction or affect its life. Only use the vacuum
cleaner on the blade section. Do not vacuum the rotating part or the main body, which can cause the fan to
malfunction or reduction of the fan’s service life.
5.3 Parts Replacement and Preservation
When replacing the parts of the robot control unit, please observe the following precautions and work
safely.
1、 Do not carry out any modification of our products.
2、 Fire, malfunction, and wrong movements caused by modification may result
in personal injury or damage to the robot.
3、 Any loss caused by the user's own modification of JAKA's products is not
covered by JAKA’s warranty.
1、 To prevent electric shock, when replacing parts, please turn off the circuit
breaker, and then turn off the main power supply.
1. Turn off the main power, wait for 5 minutes, and then the parts could be
replaced if needed.
2. There is a risk of electric shock, due to residual charge in the electronic
components.
3. Do not use wet hands for work.
4. In case of electric shock, it will result in serious injury or death.
1. 1.The replacement must be carried out by the specified operator.
2. 2.Electric shock or being caught by a robot accidentally can result in serious
injury or death.
