Daily pre-start checks · hour-based service schedule · warning actions · fluids and capacities.
Complete on level ground before the first start of every shift.
On level ground, stop the engine and allow oil to drain back; check the dipstick.
Act if: Stop if oil is below the lower mark or appears milky, foamy or fuel-contaminated. Confirm the correct grade before topping up.
Walk around and underneath the engine, hoses, radiator, pumps and tanks.
Act if: Do not start work if an active fuel, oil, coolant or hydraulic leak is found.
With the machine level and engine off, check the 80 L reservoir sight gauge or dipstick.
Act if: Top up only with the specified fluid grade; stop if the oil is milky or foaming.
Check only when the engine is cold using the recovery tank or radiator sight indication.
Act if: Top up with the specified coolant type; never remove a hot radiator cap.
Check the gauge and look for water or sediment in any drained sample.
Act if: Refuel before the next shift and investigate contamination; do not run the tank dry.
Check the clog indicator, intake hoses and clamps.
Act if: Clean or replace a restricted element and repair loose or damaged intake parts.
Inspect terminals, cables and sealed electrical connectors for looseness, corrosion or damage.
Act if: Clean, tighten or repair defects before operation.
At idle, confirm oil-pressure, coolant-temperature, hydraulic-temperature and charging indications return to normal.
Act if: Stop and investigate any alarm that remains active or any abnormal gauge reading.
Check both front-drive torque hubs for correct oil level and leakage.
Act if: Top up only with the specified oil specification; repair any leak before use.
Check wheel nuts, tyre damage, wear and cold pressure on both 23.1/26-8 PR tyres.
Act if: Correct loose or missing hardware; use the specified cold-inflation pressure.
With the engine running, check response, free play, steering cylinders and articulation joint.
Act if: Do not operate with excessive play, delayed response or hydraulic leakage.
Test the service brake at low speed and confirm the spring-applied parking brake holds and applies on pressure loss.
Act if: Remove the machine from service if either brake does not stop or hold correctly.
Inspect drum end housings and DUCONE seals for oil seepage.
Act if: Do not operate vibration if leakage is present; repair before further use.
Confirm vibration stops in neutral and when the parking brake is applied.
Act if: Do not operate if the interlock fails.
Check scraper alignment, wear and contact with the drum surface.
Act if: Adjust or replace damaged or ineffective scraper components.
Inspect canopy, mirrors, guards, steps, handrails and the anti-slip platform pad.
Act if: Repair loose or damaged protective or access components before work.
Test one front and two rear LED work lights and the four-chamber tail lamp.
Act if: Restore failed lighting before low-light or night operation.

Red means stop immediately. Amber means correct the condition before extended operation.
Immediate action: Stop the engine safely. Check the oil level and inspect for leaks before restarting.
Risk: Bearing and engine damage.
Immediate action: Allow the engine to cool; check coolant level, radiator and fan before restarting.
Risk: Cylinder-head, gasket and lubrication damage.
Immediate action: Stop operation and remove the machine from service until the neutral / parking-brake interlock is repaired.
Risk: Uncontrolled vibration and injury risk.
Immediate action: Park on firm level ground, secure the machine and remove it from service.
Risk: Loss of control, collision or roll-away.
Immediate action: Clean or replace the air element, or inspect the hydraulic filter before continuing.
Risk: Reduced performance or hydraulic contamination.
Immediate action: Check the belt, alternator wiring, battery terminals and charging circuit.
Risk: Battery discharge and electrical shutdown.
Immediate action: Stop the machine and investigate water, coolant or fuel contamination.
Risk: Bearing, seal, engine or hydraulic damage.
Immediate action: Stop vibration and repair the seal; use the machine service manual for filling procedure and quantity.
Risk: Internal drum-bearing damage.
Use clean filling equipment and confirm the specified grade before topping up or changing any fluid.
Fuel tank
Clean diesel fuel.
Hydraulic oil tank
Use the machine service manual for the correct hydraulic-fluid grade before filling.
Drum oil
5 L; service method as per machine manual.
Engine oil
Use the machine service manual for grade, sump capacity and oil/filter interval for KOEL 4R1190TA1.
Cooling system
Use the machine service manual for coolant type, mix and total system capacity.
DD / PD torque hubs
Use the machine service manual for oil grade, capacity and level procedure.
Rear axle and grease points
Use the machine service manual for axle-oil and chassis-grease specifications.
