Sandvik QA335 2015 Operators Manual – Factory Specs for the Screening Plant

If you are running a Sandvik QA335 screening plant and you do not have a copy of the factory Sandvik QA335 2015 Operators Manual on your workbench, you are working blind. I have seen too many operators skip the safety section and then wonder why the emergency stop doesn’t reset or why the hydraulic lines are leaking. This manual is 252 pages of OEM procedures, printed by Sandvik Construction Mobile Crushers and Screens Ltd. in 2015. It covers every safety principle, transport dimension, and control sequence. No aftermarket guesswork. No rewritten text. This is the original instruction file – MQA3350EN – and it is the only document you should trust when you are standing next to that machine.

Safety First: 1.1 Safety Principles and Signal Words

Chapter 1 starts on page 7 and runs deep into the specifics. You get the signal words – DANGER, WARNING, CAUTION – explained with the general hazard symbol. The manual does not assume you know what a “prohibited action” symbol looks like. It shows you. Section 1.1.4 lists safety hazards pertaining to the equipment, and 1.1.5 gives you the colour coded safety signs. If you have ever had a crew member walk into a hazard exclusion zone because the decals were faded, you know why this section matters. The manual also covers personal protective equipment (PPE) in section 1.4 and organisational safety measures including fire risk control in 1.5.1. This is not a skim-over chapter. It is the difference between a safe shift and a call to the hospital.

What Does This Manual Cover for the QA335?

The manual covers three main areas: Safety (Chapter 1, 1.1 through 1.14), Transportation (Chapter 2, 2.1 through 2.4), and Product Overview (Chapter 3, 3.1 through 3.8). Under Transportation, you get the full procedure for lowering the beacon, light mast, tipping grid, vibrating grid, side conveyors, and fines product conveyor for transport. Section 2.2 walks you through moving the machine on tracks using the wired umbilical control and the track radio remote control. Section 2.3 tells you how to secure the machine on the transport vehicle. Section 2.4 gives you transport dimensions for the tipping grid options – 4.27m (14ft) standard and 3.65m (12ft) with chute option. All dimensions are in imperial units. That is the kind of detail you need when you are loading onto a lowboy and the foreman is yelling at you.

252 Pages of Factory Procedures

252 pages is not a light binder. But every page serves a purpose. The Product Overview in Chapter 3 details the machine main components, applications, and the screening machine operation. Section 3.4 goes through the main control devices – the electrical control panel, display screen A and buttons B, mode switch C, and ignition switch E. Section 3.5 explains the display screens for auxiliary mode, operation mode, track mode, engine information, machine adjustments and diagnostics, service mode, and the active error display screen. If you have ever stared at a blinking error code on a Sandvik screen and had no idea what it meant, this manual is your decoder. The radio remote control for the reject grid and feeder is covered in section 3.6, including battery charging procedures. Track controls section 3.7 shows you how to operate and lock the remote control. All of this is factory verified. Not a single page is a reprint from a third-party site.

Check the Transport Dimensions Before Hauling

Section 2.4 lists the transport dimensions for the QA335 with different grid options. The tipping grid standard is 4.27m (14ft), the tipping grid with chute option is 3.65m (12ft), and the vibrating grid with chute option is also specified. You also get the dimensions for the side conveyors, fines product conveyor, and the screen box. If you are moving this machine between sites, you need those numbers. The manual also includes a step-by-step for lowering the tipping grid, vibrating grid, side conveyors, fines product conveyor, and the maintenance platform. Section 2.1.12 covers the fines product conveyor fold. Section 2.1.13 covers the legs. Do not guess. Measure. The manual gives you the exact procedure.

Emergency Stops: Where They Are and How to Reset

Section 1.13 covers emergency stops. Subsection 1.13.1 tells you how to stop the machine in an emergency. 1.13.2 lists the emergency stop locations. 1.13.3 explains operation of an emergency stop, and 1.13.4 tells you how to reset an emergency stop. This is not a generic description. It is specific to the QA335. If you have ever had a hydraulic line rupture and the operator could not find the emergency stop, you understand why this page is worth the price of the manual alone. The manual also covers machine guarding in section 1.14. Safety decals locations are in section 1.12. Hazard exclusion zones are in section 1.11. Vibration levels are in section 1.10.

Who Needs This Manual?

If you are a quarry operator, a screening plant foreman, or a mechanic who works on Sandvik mobile crushers and screens, this manual is for you. The audience is anyone who operates or maintains the QA335. The manual assumes you have basic mechanical knowledge but does not assume you know the specific safety procedures for this machine. It covers personnel qualifications in section 1.6, so you can verify that your crew meets the requirements. For a DIY mechanic who owns a screening plant – yes, that is a real thing – this manual gives you the same information the factory-trained technicians use. You will not find this level of detail on a forum or a YouTube video. The manual is written in English, direct from the original instruction file.

3 Reasons to Choose OEM Documentation

First, the factory manual is the only source for the correct safety decal locations and hazard exclusion zones. Aftermarket manuals often skip these details or use generic warnings. Second, the OEM manual includes the exact transport dimensions and procedures. If you use a third-party guide and the machine is 2 inches wider than you thought, you are looking at a DOT fine or a wrecked trailer. Third, the manual is the original print from Sandvik – not a scan, not a re-typed version. The OCR excerpt from page 1 shows the original instructions statement. Page 3 shows the table of contents with the exact section numbers. That is the level of authenticity you get.

Source Validity: Factory Print vs. Aftermarket

I have been burned by aftermarket manuals more times than I can count. They pull specs from a model year that does not match, or they miss the 2015 updates. This manual is the 2015 edition from Sandvik Construction Mobile Crushers and Screens Ltd., based in Northern Ireland. The copyright page states that all data and information may be changed without further notice, but that is the factory disclaimer. The content is what Sandvik put out for the QA335.

Sandvik LH203 2010 Operators Manual – Factory Specs & Safety and Sandvik QI240 Operators Manual – 258 Pages Factory Safety & Operations are also available.

External references: for understanding the difference between automatic and Manual Transmission, the principles are similar when it comes to power transfer, but do not confuse them. The same applies to Manual Transmission theory in heavy equipment.

Is this manual for the QA335 only?

Yes, it covers only the Sandvik QA335 screening plant. No other models.

Does this manual include wiring diagrams?

No. This is an operators manual, not a service or repair manual. It covers safety, transport, operation, and control displays. Wiring diagrams are not part of the 252 pages. If you need electrical schematics, you will need a separate service manual for the QA335.

Can I use this manual for a different Sandvik model?

No. The safety procedures, transport dimensions, and control sequences are specific to the QA335. Using it for another model could lead to incorrect setup or unsafe operation.

Is the manual in English?

Yes, the original document is in English. It is the factory English version from Sandvik.
