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.

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. Tur

n 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.T

he 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.

1. 1.There are a large number of connection interfaces between the printed

circuit boards. Keep cautious when replacing parts to avoid mis-insertion or

omission.

2. 2.If it causes electric shock or fire, it will result in serious injury or death.

1. 1. Do not damage the wiring or pull the connector when it is replaced.

2. 2.Do not touch the electronic components of the printed circuit boards and the

contact parts of the wiring or interface when replacing. Hold the edge of the

printed circuit board when replacing.

3. 3.If you accidentally touch them, it may cause electric shock, resulting in

serious injury or death.

1. In order to carry out maintenance and inspection work, the power should be

turned on once while the electrical cabinet’s door is ope. Do not let the inside

of the electrical cabinet be exposed to direct sunlight or searchlights,

otherwise it will cause malfunction or wrong movements.

1. 1.Before performing maintenance, the operator should discharge static

electricity in advance.

2. 2. Antistatic wrist straps are very effective.

3. 3. Failure to take any precautions when touching electrical components

directly, electrical components may malfunction.

1. Af

ter the maintenance is completed, check if there is any gap or if any cable

is caught. After that, reinstall the case. If there is a gap, it may cause dirt, dust,

etc. to enter the inside of the electrical cabinet, which will cause malfunctions.

5.3.1 Filter cleaning and replacement

1.Power off the electrical cabinet.

2.Remove the nut from the filter housing.

3.Clean the dust adhering to the filter by blowing it out. Dust should be blown from the inside of the

electrical cabinet during cleaning. When there is dirt, etc., apply warm water or a neutral detergent. And if

it still cannot be cleaned, it should be replaced.

4.Installation should be carried out in the reverse order of removal.

When cleaning with warm water or a neutral detergent, it should be fully dried before installation.

5.3.2 Part preservation

According to the life and frequency of use of the components, the recommended spare parts are divided

into two categories: A and B.

Maintenance parts • A: Main maintenance parts for daily maintenance and inspection

A-1: Important backup parts

・ A-2: Regular replacement parts / recommended spare parts

◆Maintenance parts • B: Maintenance parts prepared when purchasing multiple robots

・ B-1: Parts purchased from JAKA

In order to maintain normal operation, the A-1 and A-2 are the minimum necessary important parts. It is

recommended to prepare one whole set. In addition, the printed circuit board uses highly reliable components,

so please pay attention to the following points during storage.

•Preservation temperature -10℃～+50℃
