SANY SY220C-9 Maintenance Checklist

Daily pre-start checks · Service schedule by hours · Warning alert actions — for general earthmoving, quarry and construction duty

Daily Pre-Start Checklist

Complete these checks before every shift. They take about 10–15 minutes and help prevent damage, downtime and safety incidents.

Every Shift
1

Engine Oil Level

Dipstick — wipe clean, reinsert, then pull again to read.

Act if: below MIN — top up SAE 15W-40. White foam in oil — stop machine immediately.

2

Engine Coolant Level

Check the overflow reservoir on the engine side.

Act if: below MIN — top up coolant mix. Brown/dirty coolant — plan a flush.

3

Hydraulic Oil Level

Retract boom/arm fully with the bucket flat on the ground, then check the sight glass.

Act if: below visible range — top up. Milky white colour — water contamination, stop machine.

4

Fuel Level

Check the fuel gauge. Drain water from the sediment bowl.

Act if: below ¼ tank — refuel before the shift. Never run dry.

5

Air Filter Indicator

Check the red indicator lamp on the dashboard / the indicator on the filter housing.

Act if: red zone or indicator popped — clean or replace the primary element before starting.

6

Walk-Around Leak Check

Walk a full circle — check the ground under the machine and all hoses/joints.

Act if: any active oil drip or puddle — find the source and repair before starting.

7

Track Tension

Check sag in the track upper run — target 10–30 mm sag.

Act if: sag exceeds 50 mm — adjust tension. Very tight / no sag — loosen to prevent damage.

8

Bucket Teeth & Cutting Edge

Push/pull the bucket and inspect teeth and the cutting edge for wear.

Act if: worn teeth or a broken adapter — replace before work.

9

Horn & Backup Alarm

Press the horn button; test the backup alarm.

Act if: any failure — fix before the shift. Backup alarm not working — do not operate.

10

Seatbelt & Cab Safety

Pull the belt out fully and latch firmly. Check lockout lever operation.

Act if: belt frayed or faulty — replace before operating. The lockout lever must click into park.

11

Grease All Pin Points

Grease gun on boom, arm, bucket, linkage and swing-bearing nipples.

Every 8–10 hours minimum. If no old grease comes out, keep applying until it exits the joint.

Service Schedule by Hourmeter

Use the hourmeter reading for service timing — do not delay if a service is due. CHANGE / REPLACE = fluid or filter renewal   CHECK / INSPECT = verify condition.

Engine oil service — every 50–100 operating hours per SANY Group guidelines.

Warning Alerts & Immediate Actions

Indicators appear on the DOMCS instrument panel. RED = stop the engine immediately. AMBER = take action before continuing work.

Red — Stop engine now Amber — Act before continuing
RED

Engine Oil Pressure

Oil pressure has dropped — the engine is running without lubrication.

Immediate action: STOP ENGINE IMMEDIATELY. Do not wait. Find the cause before restarting.

Risk if ignored: complete engine seizure — irreversible. Contact your SANY dealer.

RED

Engine Overheating

Engine overheating — coolant failing, radiator blocked, or fan failure.

Immediate action: stop work. Idle 2 minutes then shut down. Check coolant and radiator.

Risk if ignored: warped cylinder head, blown head gasket, seized engine.

RED

Battery / No Charge

Alternator not charging the battery — electrical system failing.

Immediate action: check the drive belt and alternator terminal connections immediately.

Risk if ignored: machine will not restart — battery dies mid-shift.

AMBER

Hydraulic Oil Temperature

Hydraulic oil overheating — system overloaded or the oil cooler is blocked.

Immediate action: stop work. Idle 10–15 minutes with no hydraulic movement to cool the system.

Risk if ignored: pump seal failure, cylinder damage, control valve damage.

AMBER

Air Filter Restriction

Air filter blocked — the engine is not getting enough clean air.

Immediate action: stop work. Remove and inspect the outer air filter. Clean or replace.

Risk if ignored: power loss, black smoke, overheating, injector and turbo damage.

AMBER

Hydraulic Leak / Pressure Drop

Hydraulic pressure drop — a hose, joint or seal has failed.

Immediate action: stop all work. Do not operate. Locate and repair the leak before restarting.

Risk if ignored: total hydraulic failure, uncontrolled attachment movement, fire risk.

AMBER

Low Fuel

Fuel level near empty — approximately 10–15% remaining.

Immediate action: refuel as soon as possible. Do not run dry.

Risk if ignored: running dry pulls tank sediment into the injectors — expensive repair.

AMBER

Travel Motor Temperature

Final drive / travel motor oil has overheated.

Immediate action: stop machine travel. Check the final drive oil level and cooler.

Risk if ignored: final drive failure — major undercarriage repair required.
