Description

SANY PQ190III & PQ190IIIA Motor Grader User Guide

This SANY PQ190III / PQ190IIIA Motor Grader User Guide is the complete operating and maintenance manual for the SANY full hydraulic motor grader. Covering both the PQ190III and PQ190IIIA variants, this 285-page guide walks operators and technicians through every system on the machine – from the Cummins QSB6.7-C192 and Deutz TCD2012L06 diesel engines, through the hydrostatic traveling system, steering, braking, working device hydraulics, and the Siemens PLC-based electrical system, right through to the daily maintenance and lubrication schedule that keeps the grader productive shift after shift.

What This SANY Motor Grader Manual Gives You

This is not a generic “how to operate heavy equipment” book. Every procedure, torque value, and system schematic inside is specific to the SANY PQ190III and PQ190IIIA full hydraulic motor grader. The PQ190III / PQ190IIIA user guide opens with the complete machine structure and technical parameters – overall dimensions, operating weight, wheelbase, tyre size and pressure, moldboard dimensions, cutting angles, travel speeds, and the rated output and torque of each available engine.

The system description chapter is where the manual earns its keep. The transmission chapter explains the hydrostatic drive from traveling pump through hydraulic motors to the reduction tandems, including the shifting principle and the internal gear train layout. The steering chapter covers both front-wheel steering and articulation steering, with the steering trapeziform geometry, tie-rod adjustment, and the articulation lock mechanism. The brake chapter details the inner expanding drum service brakes and the spring-applied, hydraulically released parking brakes – including the manual release procedure for when hydraulic pressure is lost. The working device chapter breaks down the moldboard, slewing tooth ring, traction frame, angular device, and swing frame, explaining how the blade lifts, sideshifts, rotates, and tilts to 90 degrees for slope work.

Hydraulic and Electrical System Coverage

The hydraulic system chapter covers the closed-loop traveling circuit, the steering circuit, the service brake circuit with its accumulator and prefill valve, and the open-center working device circuit. The electrical system chapter is built around the Siemens S7-200 PLC and TD200 text display, with the full set of operation panels, instrument displays, warning lights, and the GPRS/GPS remote monitoring system that SANY fits to these graders.

Maintenance and Service Information

The maintenance chapter is organised around a tiered service schedule – 50-hour running-in service, then 100, 250, 500, 1000, 2000, and 3000-hour intervals – with specific items listed for each. You get oil change procedures for the worm gear case and reduction tandem, front axle bearing service, brake liner adjustment, parking brake friction disc inspection, hydraulic system checks, battery and electrical maintenance, air conditioning service, and the engine maintenance schedule that mirrors the Cummins and Deutz requirements.

Appendix 1 alone is worth the download: a step-by-step procedure for tipping the moldboard to the left and right sides, with the exact sequence of oil cylinder operations, the critical 80-100 mm piston extension that prevents collision, and the reset procedure to return the blade to traveling position.

Safety Content

Chapter 1 is a thorough safety section covering the warning signs and labels fitted to the machine, protective equipment requirements, safe working procedures around the moldboard and rear wheels, fire prevention and evacuation, high-pressure hydraulic safety, battery explosion prevention, and the correct procedures for parking, transporting, and welding on the machine.

Why This SANY PQ190III / PQ190IIIA User Guide Matters

The difference between a motor grader that stays on the grade and one that ends up in the shop often comes down to following the right procedure with the right values. The correct moldboard angle for the material, the right hydraulic oil temperature before working, the proper preheat cycle in cold weather, the specified torque for the wheel nuts and slewing bearing bolts – every one of these details is inside this manual. The maintenance cycle tables let you plan service by hour or calendar interval, whichever comes first, and the safety sections are written to keep operators clear of the machine’s most dangerous pinch points.
