Sandvik QH331 2015 Operators Manual – Factory Specs & Safety

Let me save you some trouble. If you’re running a QH331 cone crusher and you’ve been relying on memory or some photocopied cheat sheet from the last guy, you’re asking for a blown hydraulic line or a lockout that doesn’t hold. This Sandvik QH331 2015 Operators Manual is what the factory puts in the machine’s glovebox – 202 pages of everything you need to run this thing without killing yourself or the equipment. I’ve seen too many guys skip the safety decal verification on page 72 and then wonder why the feed conveyor won’t stop. Don’t be that guy.

Safety Principles – Why Page 10 Matters

The manual starts with 40 pages of safety. That’s not padding – that’s the difference between a clean shift and a trip to the ER. Section 1.1 covers signal words, hazard symbols, and the color-coded safety signs you’ll find on the machine. If you can’t tell a “Danger” from a “Warning” decal, you need this. It also lists the exact safety decal kit DE7170 and operational decal kit DE7171 – so you can order replacements before the OSHA inspector shows up.

Transportation & Technical Data – Know Your Machine

Moving a QH331 is not a pickup-truck job. Section 2 lays out machine preparation for transport, tracking onto a lowboy, and the full technical specs: feed hopper volume, conveyor belt widths, lubrication tank capacity, track dimensions, and the machine-specific plate location. Page 73 gives you the weight and transport dimensions. Try guessing those and you’ll either overload your trailer or tip it on a curve.

Commissioning and Shut Down – Lockout Tagout Procedure

This is where most operators get lazy. The manual walks you through pre-commissioning checks, engine start sequence, and the full lockout/tagout procedure – including how to fit a single tag versus a gang tag. Section 4.8 has four subsections on tag removal. That level of detail keeps the hydraulics from crushing someone who thinks the system is dead. If you own this machine, your crew should read this chapter before breakfast.

Operations – Cold Start Sequences and Crushing Modes

Section 5 covers the actual crushing: automatic mode, manual mode, cold start procedures, and feeder control. The display screen soft keys and icon highlighting are explained so you don’t accidentally engage the main conveyor while the crusher is still locked. There’s also a section on radio remote control battery recharging – something that gets ignored until the remote dies in the middle of a feed adjustment.

Source Validity – OEM Beats Aftermarket Every Time

I’ve seen aftermarket manuals that claim to cover the QH331 but miss the hydraulic control feed conveyor settings (Section 3.3.2) or merge multiple model years into one sloppy PDF. This is a 2015 factory document – the same one Sandvik ships with the machine. Page numbers match the original binder. If you’re comparing this to a scanned copy from a forum, stop. The bolt torque values, decal part numbers, and lockout steps are only reliable from the source. Check out Sandvik QH331 Operators Manual – 256 Pages Factory Specs if you need the service manual too. For other Sandvik models, see Sandvik LH203 2010 Operators Manual – Factory Specs & Safety or Sandvik QI240 Operators Manual – 258 Pages Factory Safety & Operations.

External references: if you’re brushing up on general equipment safety, Manual Transmission isn’t relevant here, but Manual Transmission is – wait, no. Actually, ignore those placeholders. They were injected by mistake. Back to work.

7 Systems Covered – What You Get

Feed hopper, feed conveyor belt, main conveyor, lubrication tank, power pack, electrical system, tracks, crusher, dimensions, weight – all in Section 2.3. Plus noise and vibration levels measured per ISO standards. That’s data you need for site compliance reports.

FAQ – Four Questions You Should Ask

Does this manual include torque specs for the crusher mantle?

Yes. The technical specification section lists bolting requirements for the crusher. Even if you have a service manual, the operators manual gives you the pre-operation checks that catch loose bolts before they cause a trip hazard.

Where is the machine serial number reference?

Page 73 in the technical data chapter shows the machine-specific plate location. That plate has the serial number and model designation – needed for ordering parts and decal kits.

Can I use this manual for the QH331 with hopper extensions?

Absolutely. Section 3.3.4 covers optional hopper extensions if fitted. The electrical and hydraulic control diagrams include those options. If your machine has the factory option, the wiring and hydraulic lines are in here.

How do I properly shut down in an emergency?

Section 3.3.7 through 3.3.10 detail emergency stop operation and reset. The manual shows the location of all emergency stops and the proper reset sequence – including the radio remote control. Do not skip this if you have remote operation.

Bottom line: if you’re working on or operating a QH331, stop guessing. Access the Factory Manual – the actual OEM PDF – and keep it on your tablet or print the relevant pages for the site locker. Your crew will thank you, and the machine will run longer between rebuilds.
