Do not bypass safety switches
Avoid unauthorized modifications
Do not service moving parts during operation
Turn off main power during maintenance
Keep control panels clean using a dry cloth

Weekly Safety Checks:

Main power switch functionality
Emergency stop buttons working properly
Machine stops when safety doors open

5.3 Machine Assembly

Sorter-cum-Elevator

Connect to capsule hopper
Load empty capsules
Remove defective capsules
Ensure continuous feed

Capsule Orientation & Loading

Fix cams securely to main shaft
Adjust release pin height for proper capsule drop
Align dosing plate and segment holes
Set punch penetration for accurate fill weight
Maintain air pressure: 0.5–1.0 kg/cm²

5.4 Powder Filling Process

Load powder into hopper
Maintain consistent powder level
Use tamping mechanism to form slug
Adjust dosing disc based on formulation properties

5.5 Pellet Filling (Optional)

Use volumetric filling system
Adjust dose via slider mechanism
Monitor precision using dial gauge
Ensure no pellet damage during filling

5.6 Capsule Closing & Ejection

Lock capsules using closing pins
Adjust pin size as per capsule size
Eject filled capsules via chute
Clean bushes using air/vacuum before next cycle

5.7 Machine Operation

Switch on main power
Rotate turret manually before starting
Select Auto/Manual mode
Configure settings on control panel

Key Functions:

Start/Stop – Control machine operation
