What is a lighting tower 250-hour service procedure?
A 250-hour service is the first tier of scheduled preventive maintenance for a diesel lighting tower. It is performed every 250 engine hours and is classified as a minor service. The procedure covers engine oil and filter replacement, air filter inspection, fuel system checks, mast mechanism inspection (winch cable or hydraulic cylinder), light head and lamp checks, electrical testing (auto-start, emergency stop, earthing), trailer frame and wheel inspection, greasing mast pivot points, and enclosure panel checks. Unlike a daily pre-start check (which confirms the unit is safe to operate), the 250-hour service involves actual maintenance actions: draining and replacing fluids, replacing filters, and testing mechanical and electrical systems. It is typically performed by a qualified mechanic or electrician.
Lighting towers are among the most exposed assets on a construction or mining site, operating outdoors in dust, rain and extreme temperatures. The 250-hour service interval is designed to catch wear and contamination before they cause generator failure or lamp outage during critical night operations. In Australia, lighting towers must comply with WHS Regulations 2011 and AS/NZS 3012 (Electrical Installations on Construction and Demolition Sites). Documented service records are essential for demonstrating compliance during site audits.

Benefits of using this lighting tower 250-hour service procedure
- Reduced breakdowns: regular oil, filter and coolant changes prevent engine failures that leave your site in the dark during night shifts.
- Extended component life: clean oil and correct lubrication reduce wear on the engine, mast mechanism and light heads.
- Lower repair costs: a 250-hour service costs a fraction of an emergency callout to fix a failed lighting tower on a remote site.
- Site safety: inspecting light output, mast locking, emergency stops and earthing connections at regular intervals ensures safe illumination for workers.
- Compliance: documented service records demonstrate that equipment is maintained to WHS standards, supporting insurance and regulatory obligations.
- Resale value: a complete service history increases the unit's value at trade-in or auction.

What to include in a lighting tower 250-hour service procedure
This lighting tower 250-hour service procedure covers 5 key areas:
- Engine: drain and replace engine oil (10W-30 or 15W-40), replace oil filter, inspect air filter, drain fuel/water separator, check coolant level, check fuel tank.
- Mast and lights: inspect mast mechanism, check mast extension, rotation and locking, inspect light heads and lamps/LEDs, check ballast or LED driver.
- Electrical: test auto-start system, check earthing connections and stake, test emergency stop.
- Lubrication: grease mast pivot points and winch.
- Trailer and enclosure: inspect trailer frame, wheels and jockey wheel, inspect enclosure panels and latches, check hour meter reading.
How to use this lighting tower 250-hour service procedure
- Shut down the lighting tower and allow the engine to cool. Lower the mast fully and ensure the unit is on stable, level ground.: Turn off the lights and allow the lamps to cool if metal halide. Retract the mast fully using the winch or hydraulic controls. Ensure the unit is parked on stable, level ground with outriggers deployed if fitted, and chock the trailer wheels.
- Record the equipment details and current hour meter reading at the top of the service procedure form.: Capture the unit make, model, serial number, fleet ID, site location and exact hour meter reading. Accurate hour tracking allows the next 250-hour and 500-hour service intervals to be scheduled correctly.
- Start with the engine section: drain the old engine oil, replace the oil filter, fill with new oil to the correct level, then inspect the air filter, drain the fuel/water separator and check coolant level and fuel tank.: Place a drain pan under the sump, remove the plug and drain all oil. Replace the oil filter with a new element pre-filled with clean 10W-30 or 15W-40 oil as specified. Refill to the correct dipstick level, typically 3 to 8 litres depending on the engine. Inspect the air filter for dust loading, drain the fuel/water separator bowl and check coolant level and fuel tank level.
- Inspect the mast mechanism (winch cable or hydraulic cylinder). Check mast extension, rotation and locking. Grease mast pivot points and winch.: Inspect the winch cable for fraying, kinking or corrosion, or check the hydraulic cylinder for leaks and rod scoring. Operate the mast through its full extension range and rotation, confirming the locking pin or collar engages securely at each height setting. Apply EP2 grease to all mast pivot points and the winch drum bearing.
- Inspect all light heads, lamps or LEDs for damage. Check ballast or LED driver operation.: Visually inspect each light head for cracked lenses, water ingress, damaged reflectors and loose mounting hardware. Check that metal halide lamps are not discoloured or nearing end-of-life hours. For LED units, confirm all diodes are illuminating and the LED driver is not showing fault indicators.
- Test the auto-start system (if fitted), check earthing connections and stake, and test the emergency stop.: Activate the auto-start function and confirm the engine starts and the lights switch on within the specified time. Inspect the earthing stake and cable for corrosion and confirm a solid ground connection. Press the emergency stop button and verify the engine shuts down immediately.
- Inspect the trailer frame, wheels, jockey wheel, enclosure panels and latches.: Check the trailer frame for cracks, corrosion and weld failures. Inspect wheel bearings by spinning each wheel and feeling for roughness or play. Check tyre condition and pressure. Verify the jockey wheel operates smoothly and locks in position. Confirm all enclosure panels and latches are secure and undamaged.
- Start the engine and raise the mast. Check for leaks, abnormal noises or warning lights. Test all lights at full output. Record any defects or recommendations in the notes section.: Start the engine and allow it to warm up. Raise the mast to full working height and rotate the light heads to their operating positions. Run all lamps at full output for several minutes and confirm consistent brightness with no flickering. Check for engine oil leaks, coolant leaks and hydraulic leaks. Record any findings.
- Set the next service due hours (next 250-hour and next 500-hour intervals). Sign off and update the unit's maintenance log.: Calculate the next service due hours from the current hour meter reading. Update the service sticker on the unit and enter the completed service record into your maintenance management system. Obtain the technician and supervisor signatures.

Back to download formHow often should you complete this service procedure?
The 250-hour minor service should be performed every 250 engine hours, which equates to roughly every four to six weeks for a lighting tower running continuous night shifts. The 500-hour or annual service (whichever comes first) adds filter replacements, drive belt replacement, lux meter testing, full electrical testing and trailer brake checks. Daily pre-start checks by the operator should confirm oil level, fuel, lights and mast operation before each shift. Units in dusty, sandy or coastal environments may need shorter service intervals to protect the engine and electrical systems.
For lighting towers in extremely dusty environments (mining, demolition), consider reducing the interval to 200 hours. The daily pre-start check by the operator should continue between service intervals. In MapTrack, meter-based triggers can be set for each lighting tower individually, with automatic work order generation.
