MAINTAINANCE
1.1 General Instructions
To ensure long-term, reliable operation of the PCBA Space Saver
Unloader Shuttle Multi Magazine, regular and timely maintenance is
essential. Adherence to the scheduled maintenance intervals provided
in this section will help optimize machine performance, minimize
downtime, and extend equipment life.
Important Safety Instructions:
Before performing any maintenance task, please observe the following
safety guidelines:

Disconnect power
Always unplug the machine before any
maintenance.

Observe safety warnings

Follow all posted warning signs and labels.
Especially around moving or electrical parts

Cleaning
Use a damp cloth for general cleaning. For metal
parts, alcohol may be used for effective
cleaning.

Qualified personnel only

All routine and special maintenance must be
carried out by qualified and authorized
personnel only.

Attention! ⚠ The Failure to follow these guidelines may result in serious injury or equipment
damage.
 WARNING !

⚠ Maintenance should never be performed when the machine is

powered or pressurized.

⚠ There is no voltage in the plant and the general switch is

disconnected.

⚠ The hydraulic and pneumatic circuit pressure is set to zero.

⚠ The moving parts that require fastening elements are appropriately

blocked in their stop position.

⚠ The used maintenance tools are appropriate to the required operation.

NMTronics India Pvt. Ltd. recommends carrying out regular checks

on the safety devices, and operating switches.
Please contact the NMTronics India support team for any problems or
in case of extraordinary maintenance work or modifications to be
carried out on the machine.

1.2 Maintenance Part Level Classification

To support a structured and effective maintenance program, all
components of the PCBA Space Saver Unloader are classified into three
levels based on their function, wear tendency, and criticality to machine
operation. This classification helps in prioritizing inspection schedules,
allocating maintenance resources efficiently, and minimizing
unplanned downtime.
Level 1 – Frequently Worn Parts
These components are subject to continuous mechanical stress,
motion, or friction during standard operation. As a result, they are more
prone to wear and require regular inspection and timely replacement.

1
Failure of these components can directly lead to product damage or
unplanned machine stoppage if not addressed promptly.
Typical examples are flat belts, timing belts, bearings, pulleys, ball
screw nuts, as well as other components involved in regular movement
or mechanical motion.
Level 2 – Functionally Important, Non-Essential Components
These parts contribute to the machine’s operational efficiency and
support functions but are not critical to its primary operation. Failure of
these components may impact precision or auxiliary features; however,
it does not directly impair machine functionality. Preventive
maintenance is recommended to avoid performance degradation and
undue stress on other systems.
Typical examples are indicators, LEDs, tower lamps, and selected
electrical switches, non-essential sensors etc.
Level 3 – Essential Parts
These are vital components required for the machine’s core
functionality. If any Level 3 part fails, the machine cannot operate or
may operate unsafely. These parts must be maintained meticulously,
and any fault must be addressed immediately to avoid full system
shutdown or potential hazards.
Examples include motors, servo drives, air cylinders, elevator
mechanisms, power supply cables, and safety sensors.

1.3 Maintenance Work
Maintenance is classified into four inspection intervals: Weekly,
Monthly, Quarterly, and Yearly. This structured checklist helps
monitor critical mechanical and electrical components.

Attention!

⚠ This classification system ensures that maintenance activities are

appropriately prioritized, maximizing machine uptime, safety, and
operational efficiency.

1.4 Part Replacement

Over extended periods of operation, certain mechanical components of
the conveyor system are subject to wear and deterioration. To maintain
optimum functionality, reliability, and safety of the equipment, the
following standard operating procedures shall be followed for timely
replacement of critical parts.
