# Procedure PM-001
# Quarterly Lubrication - Main Drive System

## Safety Requirements

⚠️ **WARNING**: Lock out power before performing maintenance.
Follow lockout/tagout procedure LO-001.

⚠️ **CAUTION**: Allow equipment to cool before lubricating.
Surface temperature must be below 50°C (122°F).

## Required Materials

| Item | Specification | Quantity |
|------|---------------|----------|
| Grease | NLGI #2 Lithium | 500g |
| Oil | ISO VG 68 | 1 liter |
| Rags | Lint-free | 5 |

## Required Tools

- Grease gun with flex hose
- Oil can
- Torque wrench
- Safety glasses
- Nitrile gloves

## Procedure

### Preparation

1. Complete lockout/tagout per LO-001.

2. Verify zero energy state:
   - Attempt to start equipment
   - Verify no movement

3. Allow equipment to cool if recently operated.

### Main Bearing Lubrication

4. Locate grease fitting on main bearing housing.

   [Photo showing grease fitting location]

5. Clean grease fitting with rag.

6. Connect grease gun to fitting.

7. Pump grease until slight resistance is felt
   (approximately 3-5 pumps).

   ⚠️ **CAUTION**: Do not over-grease. Excess grease
   can cause bearing overheating.

8. Disconnect grease gun and wipe excess.

### Gearbox Oil Check

9. Remove oil level plug on gearbox side.

   [Photo showing plug location]

10. Oil should be visible at plug level.

11. If low, add oil through fill port until
    oil reaches level plug.

12. Reinstall level plug and torque to 15 Nm.

### Final Steps

13. Remove all tools from equipment area.

14. Remove lockout/tagout devices.

15. Complete maintenance log entry.

## Documentation

Record the following in maintenance log:
- Date and time
- Technician name
- Grease quantity used
- Oil added (if any)
- Any observations

# Troubleshooting Guide
# Model: [Equipment Model]

## Symptom: Equipment Will Not Start

### Possible Causes

| Priority | Cause | Probability |
|----------|-------|-------------|
| 1 | No power | High |
| 2 | Emergency stop engaged | High |
| 3 | Safety interlock open | Medium |
| 4 | Control fault | Medium |
| 5 | Motor failure | Low |

### Diagnostic Steps

**Step 1: Verify Power Supply**

Check main disconnect:
- Position should be ON
- Indicator light should be lit

| Result | Action |
|--------|--------|
| Disconnect OFF | Turn ON, retry start |
| Disconnect ON, no light | Check upstream power |
| Disconnect ON, light on | Go to Step 2 |

**Step 2: Check Emergency Stop**

Verify all E-stops are released:
- Main panel E-stop
- Remote pendant E-stop
- Guard interlock E-stop

| Result | Action |
|--------|--------|
| Any E-stop engaged | Release and reset |
| All E-stops clear | Go to Step 3 |

**Step 3: Check Safety Interlocks**

Verify all safety interlocks:
- Guard doors closed
- Safety mats clear
- Light curtains clear

| Interlock | Location | Status Indicator |
|-----------|----------|------------------|
| Guard door | Front panel | Green = closed |
| Safety mat | Floor area | Green = clear |
| Light curtain | Entry point | Green = clear |

# Fault Code Reference

## Error Code Format

E-XXX-YY

- XXX: System code
- YY: Specific fault

## Fault Code Table

| Code | Description | Cause | Action |
|------|-------------|-------|--------|
| E-100-01 | Motor overtemp | Overload or cooling fault | Check motor load, verify cooling |
| E-100-02 | Motor overcurrent | Mechanical bind or short | Check for obstruction, inspect wiring |
| E-200-01 | Low hydraulic pressure | Pump failure or leak | Check pump, inspect for leaks |
| E-200-02 | High hydraulic temp | Cooler failure or overwork | Check cooler, reduce duty cycle |
| E-300-01 | Sensor failure | Sensor damaged or disconnected | Replace sensor, check connections |

## Detailed Fault: E-100-01

### Motor Overtemperature

**Description**: Motor temperature exceeds safe limit.

**Possible Causes**:
1. Motor overloaded
2. Cooling fan not operating
3. Ambient temperature too high
4. Motor bearing failure

**Diagnostic Steps**:

1. Allow motor to cool (minimum 30 minutes)

2. Check motor load:
   - Run equipment unloaded
   - If fault clears, check for mechanical binding

3. Verify cooling fan operation:
   - Fan should start when motor runs
   - Check fan motor and wiring

4. Check ambient conditions:
   - Ambient should not exceed 40°C
   - Verify adequate ventilation

5. If fault persists, contact service.
