Hisun Rhino HS500/600/700 UTV Service & Repair Manual

• Coverage and document structure: A 390-page PDF with 15 pages of cover, foreword, and contents followed by 375 numbered manual pages. The HS700-focused handbook occupies numbered pages 1-346, the HS600 supplement pages 347-349, the HS500 supplement pages 350-374, and the shared HS700/HS600/HS500 wiring diagram page 375.
• Engine and CVT repair: Covers engine removal; cylinder-head, camshaft, rocker-arm, valve, cylinder, and piston service; cooling-fan and A.C. magneto work; balancer and oil-pump gears; primary and secondary sheaves; centrifugal clutch; crankcase, crankshaft, oil pump, transmission, middle drive, and carburetor repair.
• Chassis and driveline procedures: Details rack-and-pinion steering, front and rear disc brakes, master-cylinder and caliper service, wheel hubs and CV joints, front and rear bridge assemblies, differential inspection and gear-lash adjustment, reverse-mechanism adjustment, and front and rear suspension repair.
• Maintenance and adjustment: Includes the scheduled-service chart plus valve-clearance, throttle- and starter-cable, ignition-timing, compression, brake, select-lever, toe-in, shock-absorber, battery, and headlight procedures.
• Electrical diagnosis: Provides continuity, voltage-drop, peak-voltage, and short-circuit test methods; starter-motor and charging checks; troubleshooting for ignition, lighting, signaling, cooling, and 2WD/4WD selection; and circuit diagrams for those systems.
• Workshop data and illustrations: Supplies component torque tables, fluid and lubricant specifications, wear limits, clearances, gear-backlash data, electrical test values, exploded assembly drawings, troubleshooting charts, and the final full-vehicle wiring schematic.

Model Coverage and Manual Scope

The foreword identifies the Technical Center of Chongqing Huansong Industries (Group) Co., Ltd. as the editor and states that the handbook was supplied to dealers and technicians. It also makes an important distinction: the main repair content is for the HS700UTV. The HS600UTV supplement is limited to model-specific general and engine specifications, while the HS500UTV supplement adds specifications and separate procedures for engine removal, the cylinder head and timing-chain tensioner, camshaft and decompression system, valves and springs, and the cylinder and piston. The specification sections distinguish the three platforms by their 686 cc, 608 cc, and 471 cc engines.

The added cover markets the manual for HS500/600/700 Rhino clones and names Bennche, BMS, Big Muddy, JMC, Massimo, Powermax, Precision, QLink, Supermach, and Yardsport rebadges. The technical pages do not provide a badge-by-badge cross-reference, so match the frame and engine identification, displacement, brake layout, and drivetrain configuration before ordering parts or selecting a repair procedure.

Repair and Diagnostic Depth

This is more than a maintenance guide. Engine chapters include removal and installation, internal inspection, wear measurement, valve-seat and guide work, cam timing, piston and ring checks, crankcase and bearing service, CVT sheave disassembly, clutch inspection, carburetor float and fuel-level adjustment, and transmission teardown. Chassis coverage extends to brake bleeding and hydraulic component repair, steering-column service, differential and bridge disassembly, shim selection and gear-lash measurement, U-joint service, suspension-arm inspection, radiator testing, and water-pump mechanical-seal replacement.

Named workshop equipment includes the sheave fixed block, locknut wrench, sheave spring compressor, sheave and clutch holders, gear-lash measurement tool, ring-nut and bearing-retainer wrenches, universal-joint holder, radiator-cap tester and adapter, valve-spring compressor, water-pump seal installers, compression and leak-down gauges, and electrical pocket tester. That depth makes this manual best suited to technicians and experienced mechanics who have measuring tools, pullers, holding fixtures, and safe lifting equipment.

The illustrations include exploded views for the valve train, primary and secondary sheaves, steering column, brake calipers, front differential/bridge, and water pump. Electrical coverage is similarly specific, with ignition, electric-start, charging, lighting and signaling, cooling-fan, and 2WD/4WD selector circuit diagrams, followed by the shared full-vehicle schematic.

Two details show why the correct procedure matters. The middle driven-shaft bearing retainer uses left-hand threads; forcing it in the normal direction can damage the threads. The universal-joint section also warns that needle rollers can fall out of their races, and forcing the yoke with a displaced needle can damage the bearing. Securely support the UTV before chassis or driveline work, let the cooling system cool before opening it, and keep fuel-system service away from ignition sources.
