Verify all intervals, fluid grades, fluid volumes, torque values and alarm set-points with the official SANY SR285R O&M manual before service.

Daily / Every Shift Checklist

Complete before every shift, approx. 15–20 minutes. Do not operate if any check fails or cannot be confirmed.

Every Shift
1

Check dipstick with engine cold on level ground. Top up if below MIN. Typical reference grade: API CI-4 or better, SAE 15W-40.

Act if: Below MIN mark or oil is milky / black-discoloured — do not start engine.

2

Engine Coolant

Check expansion tank level. Top up with correct coolant mix.

Act if: Level below MIN, coolant is brown/rusty, or any external leak is visible.

3

Fuel Level

Check fuel gauge, fill with clean diesel, and drain water from the fuel pre-filter bowl.

Act if: Fuel below 25% capacity or water / contamination is found in the bowl.

4

Hydraulic Oil

Check sight glass on hydraulic tank. Top up if below lower mark.

Act if: Below lower mark, milky oil, or any leak at hose connections.

5

Air Filter

Check restriction indicator lamp on the instrument panel.

Act if: Restriction lamp is illuminated — do not start; replace filter first.

6

Battery

Check terminal tightness and corrosion. Check electrolyte level if accessible.

Act if: Loose terminals, severe corrosion, or electrolyte below MIN mark.

7

Central Lubrication

Check grease reservoir level and confirm auto-lube pump cycles on startup.

Immediate action: Stop work, inspect for leaks, and top up with correct grade before resuming.

Risk if ignored: Pump cavitation, component wear and hydraulic failure.

AMBER

Battery / Charging Fault

Alternator output low or battery weak.

Immediate action: Check alternator belt and terminals. Charge or replace battery.

Risk if ignored: SANY-ADMS shutdown and complete electrical failure.

AMBER
