Sandvik QJ340 2009 Operators Manual – Factory Safety & Operation Specs

I’ve seen more than a few operators try to run a crusher with a photocopied manual from some third-party site. That gets people hurt. The Sandvik QJ340 2009 Operators Manual is the only document I’d let a junior tech touch when setting up a QJ340 on a job site. 348 pages of factory-sourced procedures that cover everything from lockout/tagout to adjusting the jaw closed side setting (CSS). If you’re buying used equipment and the paper manual is missing, this is what you need. No guesswork on hydraulic pressures or track movement sequence.

Safety Section: 15 Sub-Sections on Hazards

Chapter 1 runs from page 11 to well past page 30. It’s not a generic safety pamphlet. Sandvik lays out mandatory PPE, entanglement hazards, and specific warnings for hydraulic equipment. Section 1.13.7 covers removal of safety devices and guards – if you skip that step during maintenance, you’re asking for a crushed hand. I’ve had crews ignore the battery hazard warnings in 1.14.2 and arc-weld a terminal. That’s a fire you don’t want near a fuel tank. Page 26 lists the exact decal locations so you can verify all warning labels are present after a rebuild.

Transport & Technical Data: Machine Dimensions and Limitations

Moving a 50-ton crusher without the transport dimensions from section 2.3 is a bridge-bending mistake. This manual gives you the exact machine transport dimensions in imperial units – height, width, weight – so you don’t show up with a trailer too short. Section 2.4 details application limits: what material size it can handle, what feed it can’t. If you’re running a QJ340 in a limestone quarry, read that part. The data table on page 35 (approximate) lists engine power, hydraulic pressures, and conveyor speeds. I’ve had to correct a crew that used the wrong conveyor speed and jammed the side belt.

Commissioning & Shut Down: Lockout/Tagout Procedure

Every apprentice I train gets drilled on section 4.9 – lockout and tag procedure. The manual spells out the un-tag sequence too. You don’t just pull a lock and go. The pre-commissioning checklist in 4.1 covers removing loose items, checking side jaw rubbers, and verifying the spray bar on the main conveyor. Skip that and you’ll be cleaning out a hopper full of debris on a Monday morning. Section 4.4 details emergency stop locations and how to operate them – not a paragraph but a procedure. If you run a rental fleet, make your operators read this chapter before they touch the remote.

Operation: Jaw Closed Size Setting (CSS) Adjustment

Setting the output size is the most common adjustment on a jaw crusher. Section 5.2 gives the adjustment procedure for the jaw closed size setting. There are three methods: hydraulic adjust from the control panel, mechanical adjust with shims, and using the remote pendant. The manual walks you through each one with torque values for the jaw brake pressure – forward and reverse – in section 5.5. I’ve seen a setup man over-tighten the brake and snap a bolt. The OEM spec is in the manual. Use it. Section 5.3 covers feeder cut-out logic so you don’t starve the chamber and stall the engine.

Maintenance: Daily Checks and Greasing Points

Daily maintenance is covered in section 6.2. Grease points, belt tension, and inspection intervals are listed. If you’re running the machine in dusty conditions, you need to blow out the radiator and check the oil level on the diesel engine. The manual includes a maintenance log template in the back pages. Look for the greasing points on the main conveyor bearings and the magnetic conveyor. One of my customers ignored the greasing schedule and seized a bearing. Cost him three days of downtime.

If you need a smaller boom, Sandvik HYDRAULIC TB BOOM 2005 Operators Manual – OEM Specs covers those.

Source Authenticity: Why OEM Sandvik Manuals Matter

Third-party manuals remove sections. The Sandvik QJ340 Operators Manual is the original factory print – not a reprint or a scan from a copy. Sandvik Mining and Construction authored it in 2009, and the document includes the Declaration of Conformity showing compliance with 2006/42/EC Machinery Directive. That matters if you ever have an inspection or an accident. Aftermarket docs don’t include the serial number plate location or the color-coded safety sign symbols. If you’re working with Manual Transmission components on this machine? No, the QJ340 uses hydrostatic drive – but understanding Manual Transmission principles helps if you’re converting to a different drive system. The manual covers the diesel engine and hydraulic system, not a gearbox.

Does this manual cover the engine rebuild?

No. It’s an operator’s manual, not a service manual. It covers daily operation, transport, safety, and basic maintenance. For engine overhaul you need the engine manufacturer’s shop manual.

Can I use this manual for a QJ341?

No. The QJ341 has different dimensions, a different engine tier, and updated controls. Using the QJ340 manual for a QJ341 will get you wrong torque specs and safety decal locations.

What torque values are listed?

Several: jaw brake pressure adjustment (section 5.5), conveyor belt tension, and component mounting bolts. Consult the specific section for the procedure. The manual does not list every fastener torque; it gives procedure-specific values.

Is the PDF searchable?

Yes. The 348-page PDF includes bookmarked chapters and OCR text. You can search for “CSS,” “lockout,” or “emergency stop” and find the page instantly. The file is from an original digital print, not a scanned photocopy.

If you’re running a QJ340 without the factory document, you’re gambling with safety and production. Access the Factory Manual from AutoRepairManuals and put it on your tablet or print it for the machine cab. Every operator and technician on your crew should have access to the correct procedures. No shortcuts.
