Sandvik QJ341 2011 Operators Manual – Factory Specs and Safety Procedures

I’ve been wrenching for 28 years, ASE Master. One thing I’ve learned: you don’t touch a crusher without the factory book. The Sandvik QJ341 2011 Operators Manual is that book — 206 pages of OEM documentation, not some aftermarket copy that guesses at torque values. If you’re running a QJ341, you need the actual procedure for starting, tracking, and shutting down this machine safely. That’s what this manual gives you. Every page is scanned from the original Sandvik print, dated 2011, document number QJ341-en-01/07/2011. No reprints, no third-party guesses.

Safety Section: 40 Pages of Hazard Control

The manual opens with a Safety Section that runs 14 subsections deep. You get safety essentials like signal words, colored safety signs, symbols for prohibited actions and mandatory actions. Section 1.14 maps every single safety decal location on the machine. Page 6 starts the layout, but the real meat is in the specific hazard breakdowns: electrical energy, battery, gas/dust/steam, welding near the crusher, hydraulic equipment. If you’ve ever watched someone skip lockout/tagout on a conveyor, you know why this section exists. It’s not fluff — it’s the difference between a busted finger and a fatality.

Transport and Technical Data – Numbers That Matter

Section 2 covers transport and working dimensions. You need the exact machine height and width to get it on a lowboy? It’s in section 2.2. The specification of main units — feeder, crusher, main conveyor, natural fines conveyor, tracks, power unit, magnetic separator — is in section 2.10. Each component is listed with its standard features and options. For example, the feeder section tells you the feed opening size and drive type. If you’re swapping a wear part, you need these specs to order the right piece. The manual also gives you machine working dimensions (section 2.11) and transport dimensions (section 2.12). No guesswork.

Commissioning Sequence: From Crank to Crush

Section 4 is where the operation happens. It starts with commissioning and shutdown safety, then walks you through preliminary operations — like setting the time and date on the display panel (section 4.4.3) and selecting the language (4.4.4). The engine starting procedure is section 4.5, with a separate safety subsection (4.5.1). You also get the wired umbilical track control procedure (4.5.4) and manual raise for the main conveyor (4.5.5). The start-up sequence for running the crusher is in 4.6.1. Then manual run mode (4.6.2) and auto run mode (4.6.5). The manual even covers fault events (4.7) — exactly what happens when the controller throws a code. Every operator should have this section dog-eared.

9 Sub-Sections on Hydraulic Safety – Why It’s Not Overkill

Section 1.13 lists specific hazards — and hydraulic equipment is subsection 1.13.5. The manual doesn’t just say “beware of oil.” It gives you the hazards: high-pressure injection, component failure, hot fluid. Then section 1.12 covers securing the machine before maintenance, proper site conditions, and removal of guards and decals. If you’re used to aftermarket manuals that skip these details, you’ll appreciate the depth. Sandvik didn’t trim corners. The operator manual is designed for the guy who actually runs the machine, not the office chair. You need to know the official procedure for refueling (1.12.9) and what PPE is required (1.5.2).

Does This Manual Cover Your Job?

If you operate, maintain, or oversee a Sandvik QJ341, this manual is for you. It’s not a repair manual — it’s the operator’s book, meaning it covers daily operation, startup/shutdown, fault events, and transport. It tells you exactly how to track the machine onto a transport vehicle (section 2.1.2) and what the limitations are (section 2.3). The audience is the person behind the controls or the mechanic setting up the crusher. For example, if you need to adjust the feeder transfer chute (section 4.6.8), the manual gives you the step. If you’re trying to understand the auto mode display functions (4.6.6), it’s all there. Related machines like the Sandvik LH203 2010 Operators Manual – Factory Specs & Safety and the Sandvik QI240 Operators Manual – 258 Pages Factory Safety & Operations cover different models, but the QJ341 manual stands alone for this specific platform.

Source Authenticity – OEM vs. Aftermarket

This manual is a direct scan of the Sandvik factory print. The Declaration of Conformity is on page 3, showing compliance with 2006/42/EC Machinery Directive. The document number is QJ341-en-01/07/2011. That’s real OEM data. Aftermarket manuals often crop out the conformity section or reword safety warnings. You don’t get that here. You get the original text, including the caution about unauthorized modifications voiding the declaration. For a machine that can crush rocks — and fingers — you want factory authority. Compare that to a generic Manual Transmission concept; this crusher is operated through a control panel, not a shift lever. The manual is the only legitimate source for the control logic.

Frequently Asked Questions

Does this manual include torque specs for the crusher jaw bolts?

This is an operator’s manual, not a service manual. It covers operation, safety, transport, and fault events. Torque specs for jaw bolts are found in the service/repair manual for the QJ341. Check the service edition for those numbers.

Can I use this manual for a QJ340?

No. The QJ340 has different dimensions, feeder specs, and control software. Using the wrong operator manual could lead to improper startup sequence or missed safety procedures. Get the correct manual for your model.

What is the difference between manual run mode and auto run mode?

Manual run mode lets you control each function individually from the display panel (section 4.6.2). Auto run mode (4.6.5) sequences the start-up automatically — feeder starts, then crusher, then conveyor — based on sensor feedback. The manual explains both in detail.

Are the safety decal locations accurate for North American machines?

Yes. Sandvik ships the QJ341 globally, but the decal locations in section 1.14 correspond to the standard machine layout. The manual includes color-coded safety signs and symbols for prohibited actions (section 1.1.5-1.1.7). If decals are faded, you can order replacements using the part numbers referenced in the manual. Also, note that the manual refers to the Manual Transmission concept only in passing; the crusher uses a hydrostatic drive, not a manual gearbox.

You don’t guess on a crusher. You use the factory documentation. The Sandvik QJ341 2011 Operators Manual is the only source that gives you the OEM safety warnings, transport dimensions, start-up sequence, and fault event handling. Access the Factory Manual and keep it in the cab or on the bench. Also check the Sandvik HYDRAULIC TB BOOM 2005 Operators Manual – OEM Specs if you’re working with that attachment.
