1999 New Holland LS190 Skid Steer Loader Operator's Manual (P/N 86589933)

The New Holland LS190 operator's manual, document 86589933, 7/99 edition, covers the 1999 skid steer loader with the 450/NC diesel engine and two-speed hydrostatic drive. It addresses operation, maintenance, troubleshooting, and adjustments. Major internal engine and hydrostatic repair requires the separate service manual.

Finding maintenance information: PDF text search is available across the text chapters. Embedded bookmarks lead to the contents, Safety, all seven numbered sections, and the index.

This single, printable 148-page PDF includes one cover, two owner-information/warranty pages, one contents page, two index pages, and five blank pages within the total. The delivery report and publications order form referenced in the contents are not included.

Loader Operation, Drivetrain Adjustments, and Maintenance

These selected topics cover the main operating and maintenance areas. Additional material includes storage preparation and material-weight tables for bucket selection.

• Engine and cooling: Instructions cover fuel bleeding, air-cleaner service, engine oil and filter changes, cooling-system cleaning, and alternator-belt replacement.

• Hydrostatic controls: Adjustment procedures address neutral, equal lever movement, straight travel, forward/reverse stops, and the high/low-range linkage.

• Final drive and brakes: Coverage includes chain-tension adjustment, sprocket and chain routing, gearbox/chain-case lubrication, and parking-brake linkage settings.

• Boom and auxiliary hydraulics: Standard foot controls and optional hand controls receive operating and linkage-adjustment coverage, alongside hydraulic troubleshooting and high-flow operation.

• Electronic Instrument Cluster: Coverage explains warning displays, automatic shutdown, seat and seat-belt interlocks, spool locks, fault codes, and starting problems.

• Cab and attachments: Step-by-step cab-tilting instructions accompany jack-kit requirements, quick-attach operation, bucket-selection guidance, and pallet-fork capacity charts.

Written for owners and operators, the manual also covers drivetrain adjustments and cab-tilting work that require mechanical experience and the specified support equipment.

Operating Controls and EIC Faults

Prestarting checks and cold-weather starting guidance accompany instructions for entering, leaving, and escaping the cab. Attachment handling uses the Pick-up and Go quick-attach mounting system.

The EIC front-panel illustrations identify monitored functions and warning symbols. Codes F0A, F03, and F04 distinguish faults in the hydraulic boom/bucket solenoid, engine-preheat relay coil, and fuel-solenoid circuits.

Problem/cause/correction tables address starting failure, locked boom and bucket controls with the engine running, low hydrostatic charge pressure, noisy pumps, and slow hydraulic movement. Electrical coverage provides basic fault isolation and interlock checks; electrical wiring diagrams are not included.

Drive Linkages, Chain Routing, and Cab Access

The drivetrain sections provide a reference for checking control setup and mechanical adjustments. For a loader that creeps in neutral, the neutralizer and linkage procedures support those checks before more extensive hydrostatic repair is considered.

Coverage extends to dampeners, equal-stroke alignment, and travel stops. Wheel-speed adjustment uses a handheld tachometer; the manual warns that incorrect external stop settings can overspeed the transmission and damage it or the control linkage.

The Final Drive Chain Routing illustration distinguishes front and rear sprocket arrangements. Cab-tilting instructions identify jack supports, retaining hardware, and reinstallation details, including the risk of electrical-component damage if the wiring harness becomes trapped beneath the cab.

Before adjustments or major repair preparation, follow the manual’s boom-support and machine-support precautions. Cab tilting requires the specified New Holland cab jack kit.

Engine Service and Maintenance Schedules

The Lubrication Location Chart and Service and Maintenance Location Chart connect scheduled work with illustrated service points. Interval tables separate break-in requirements from recurring maintenance and explain when severe conditions call for shorter intervals.

Engine-service instructions distinguish the primary air-filter element from the inner safety element. Fuel-system coverage includes the water trap and bleeding with the electric fuel pump.

Cooling-system procedures address flushing and cleaning between the radiator and hydraulic oil cooler. Alternator-belt illustrations show routing and the automatic spring-loaded tensioner.

Hydraulic Options and Attachment Selection

Control descriptions distinguish standard boom/bucket foot pedals from optional hand controls, including the corresponding change in auxiliary-hydraulic control layout. Optional high-flow hydraulics and the independently operated front or rear remote-hydraulic system are also described.

The Bucket and Tire Combination Chart supports attachment selection. Pallet-fork tables distinguish configurations with and without rear counterweights, while reference sections provide tire inflation, operating loads, dimensions, cold valve clearances, fluid capacities, and hydraulic pressures.

One specifications page is labeled Lx985 and contains inconsistent hydraulic capacities and battery figures that differ from the maintenance section. That table should not be treated as an unqualified LS190 specification reference.

A Preview of Cooling Pressure and Cold Valve Clearances

Cooling-system guidance includes a pressure specification of 13 PSI, together with coolant-mixture and flushing instructions.

For the 450/NC engine, the specification table lists cold valve clearances of 0.016 in. (0.406 mm) for the intake valves and 0.019 in. (0.483 mm) for the exhaust valves. These are reference specifications, rather than a detailed valve-adjustment procedure.
