1. Pre-Operation Checks (10-15 Minutes)

Fluid Inspection:

• Engine Oil: Check dipstick level 5 minutes after shutdown (keep between MIN~MAX marks).

• Hydraulic Oil: Ensure level is at 1/2~2/3 of the sight glass (clear, no emulsion).

• Coolant: Verify level in the reserve tank (no rust/sediment).
  (Example: Replace immediately if oil is black or hydraulic fluid is cloudy.)

Visual Inspections:

• Tires/Tracks: Confirm tire pressure (wheeled) or track tension (tracked) meets specs.

• Brakes: Check for leaks; pedal should rebound promptly.

• Lights/Gauges: Test all indicators, horn, and headlights.

Lubrication:

• Grease pivot pins, bucket linkages, etc., until old grease is purged.

2. Operational Precautions

• Temperature Monitoring:

• Engine coolant ≤ 95°C, hydraulic oil ≤ 80°C (stop if overheated).

• Abnormal Noises/Vibrations:

• Halt operation if unusual sounds (e.g., grinding) occur; inspect bearings/drivetrain.

• Avoid Overloading:

• Never exceed rated bucket capacity (hydraulic cylinder shuddering indicates overload).

3. Post-Operation Maintenance

• Cleaning:

• Pressure-wash tires/tracks and undercarriage; clear radiator fins (prevents clogging).

• Drain Water Separator:

• Release water from diesel filter drain valve (critical in cold climates).

• Tighten Loose Parts:

• Secure wheel bolts, bucket pins, etc. (refer to manual for torque specs).

4. Periodic Maintenance Schedule

5. Seasonal Adjustments

Winter:

• Use low-pour diesel (#-10 or lower) and antifreeze (freezing point ≤-30°C).

• Preheat engine (30s glow plug activation if equipped).

Summer:

• Clean radiator of debris; check fan belt tension (10mm deflection = normal).

6. Common Maintenance Mistakes

• Mixing hydraulic oil brands → Additive reactions cause sludge.

• Over-greasing fittings → Seal damage and dirt accumulation.

• Spraying electrical parts with water → Short circuits.

Following these steps extends loader lifespan by 30%+ and reduces breakdowns!
