Atlas Copco QLT 4 2010 Operators Manual

This is the factory Atlas Copco QLT 4 2010 Operators Manual. 48 pages. Original OEM documentation, not a reprint from some third-party that leaves out torque specs and safety warnings. I’ve seen too many burned-up light towers because someone guessed on the fuel system bleed procedure or skipped the coolant check. This manual gives you the exact set-up, operation, and maintenance steps Atlas Copco engineers wrote. Period.

Specifications: Engine, Alternator, and Lamps

Section 1 of the manual lays out everything you need to know before you run the machine. Reference conditions, overall limitations, performance data. I’m talking about the engine (rated output, fuel consumption), alternator voltage and frequency, lamp output in lux at various distances, undercarriage dimensions, controller specs. Page 6 gives you the charge pressure and oil type requirement for the engine. You need that to pick the right lubricant. The manual includes a table of average lightening versus distance – that tells you how many lux you get at 10 feet versus 50. If you’re lighting a construction site, that’s the data you use to position the tower. Don’t guess.

What Does the 48-Page Manual Cover?

Everything from setup to teardown. Chapter 1: Specifications. Chapter 2: Identifying instruments and controls – the operation panel, every switch and warning light explained. Chapter 3: Light tower operation – safe setup, starting the engine, operating the lights, shutdown, lowering the mast, moving the machine. Chapter 4: Maintenance and charging – service intervals with a maintenance schedule, battery charging, fuel system bleeding, oil changes, coolant checks. Then a full parts list with exploded diagrams and part numbers. This is the complete field guide for the QLT 4.

Safe Operation: The Section You Cannot Skip

Section 3.1 is titled “Safe operation” and it covers six sub-sections: observe safety instructions, wear safety clothing, safe handling of fuel and lubricants (fire prevention), pre-operation checks, keep the engine and engine area clean, exhaust gasses and fire prevention. I’ve seen guys skip the pre-operation check and then wonder why the low oil pressure light comes on. This manual tells you exactly what to check before turning the key. Skip that and you risk a fire.

3 Critical Maintenance Tasks You Must Follow

First, fuel system air bleeding (Section 4.4) – if you run the tank dry or change the filter, you need to bleed the lines. The manual gives a step-by-step procedure, not a vague “open the bleed screw”. Second, engine oil change with filter cartridge replacement (4.7.2 and 4.7.3). Third, coolant level check and overheating precautions (4.8). Each task has torque values and capacities. The maintenance schedule (4.1.1) lists intervals in hours of operation. Stick to it.

Get the Right Parts with the Factory Parts List

From page 25 onward you get parts lists, parts index, and ordering instructions. Exploded diagrams show every component – alternator, engine, lamps, undercarriage, controller, cubicle. Part numbers like 1310 4682 00/00 and 1310 4700 00/00 are printed. Ordering spare parts directly from Atlas Copco is straightforward with these numbers. Aftermarket catalogs often use generic substitutes; don’t gamble. Use this manual to get the exact factory part.

For reference on general drive system concepts, see Manual Transmission and Manual Transmission. While the QLT 4 doesn’t use a manual transmission, understanding factory procedures for any mechanical system starts with the same principle – use the OEM documentation.

Does this manual cover the QLT 4 engine?

Yes, engine specs and maintenance are on pages 6-8.

What parts are included in the parts list?

The manual’s parts list (starting page 25) includes exploded diagrams and OEM part numbers for every component – alternator, engine, lamps, undercarriage, controller, and cubicle. It lists specific numbers like 1310 4682 00/00 and 1310 4700 00/00. Using these ensures you get the correct replacement from Atlas Copco. Aftermarket parts catalogs often list generic substitutes; that’s a gamble. With this manual, you order exactly what the factory intended. That alone saves you from ordering the wrong lamp housing or filter cartridge.
