Description

Doosan D50S-5 to G70S-5 Forklift Operation and Maintenance Manual (SB2356E01)

This is the complete Doosan D50S-5, D60S-5, D70S-5, D80S-5, D90S-5, G50S-5, G60S-5 and G70S-5 counterbalanced forklift operation and maintenance manual, published under document number SB2356E01. It covers the diesel D50S-5 through D90S-5 machines powered by the Doosan DB58S 5.8-litre engine, and the LP-gas G50S-5 through G70S-5 machines powered by the GM Vortec 4.3-litre G643E engine. Every capacity chart, warning decal location, torque figure, lubrication interval and procedure from the original operator’s book is included in this PDF.

Safety Section

The opening of the Doosan D50S-5 / D90S-5 operation manual reproduces every warning sign and label used on the truck, with a photo showing its exact position on the machine. General hazard information, mounting and dismounting procedure, pre-start walk-around, seat switch behaviour, operator restraint system (seat belt fasten, inspect and release), lift truck stability theory (centre of gravity, stability triangle, capacity load, load centre) and the full tipover survival sequence are all covered. Dedicated safety pages address pressure systems, hand placement, no-rider rules, moving fan, load backrest, overhead guard and parking brake decals, plus fire and explosion prevention, tire inflation danger zones, battery and ether safety, and fluid-penetration first aid.

General Section

Model-by-model specification tables for all eight trucks — capacity at rated load centre, load centre distance, tyre type, wheelbase, tilt angles, overall dimensions, turning radius, travel and lift/lower speeds, gradeability, axle load, tyre sizes and pressures, brake type, battery rating, engine output and torque, and transmission type. Capacity charts are reproduced for both the standard mast and full free lift masts, with side shifter variants also included for the larger models. Noise and vibration values, serial number locations for the truck, diesel engine, LP engine, transmission and drive axle, and full explanation of the Operator’s Warning plate, Identification plate, mast abbreviations and attachment abbreviations are provided.

Operation Section

Operator’s station layout (steering wheel, direction control lever, lift and tilt levers, inching pedal, service brake, accelerator, parking brake, instrument panel, warning lights, transmission display). Seat switch system behaviour, direction control forward/neutral/reverse and 1st/2nd/3rd speed selection, neutral lever lock, automatic transmission switch, inching switch and pedal operation. Diesel and LP starting procedures (including cold diesel preheat), jump-starting from a 24V/12V external source, refuelling and LP tank changeover, post-start gauge and warning light checks. Lift truck operation, inching into loads, traveling with the load, unloading, turning, hot weather operation, parking, lift fork adjustment, storage preparation and towing procedure. The Auto Shift Controller ASC-200/201 chapter explains the low/high shift point, direction inhibit point, automatic and manual (fail-safe) modes, and display diagnostics for the two-speed diesel and LP models.

Maintenance Section

Inspection, maintenance and repair of lift truck forks (fork failure causes, daily, 12-month and first-installation inspection, load testing after repair). Tire inflation pressures and safety. Full torque specification tables (metric fasteners, SAE bolts and nuts, taperlock studs, hose clamps). Cooling system, fuel and lubricant specifications including refill capacities for D50/60/70/80/90S-5 (3-speed), D50/60/70S-5 (2-speed) and G50/60/70S-5. Detailed maintenance schedule by interval — When Required, Every 10 Service Hours or Daily, First 50-100 Hours, First 250 Hours, Every 250, 500, 1000, 1500, 2000 and 2500 hours — with step-by-step procedures for engine oil and filter change, transmission oil and filter change, drive axle oil change (shoe brake and OCDB), parking brake test and adjustment, hydraulic filter and strainer, air intake service, coolant change, lift chain wear test and adjustment, steer wheel bearing reassembly, LP fuel filter element, fuel lock-off test, spark plug replacement and oxygen sensor replacement. Diesel valve lash values, fuel system priming, and G643 / G643E diagnostic fault code tables with MIL flash code reading procedure are also included.

Everything You Need to Run and Maintain a D50S-5 through G70S-5

Because Doosan designed these five diesel and three LP-gas models as one counterbalanced series, this one manual covers daily checks, scheduled services, common fault diagnosis and safety procedures for the entire range. Whether you are an owner-operator keeping a D70S-5 on a warehouse floor, a fleet technician responsible for a mixed diesel and LP fleet, or a workshop handling a D90S-5 or G60S-5, the correct torque, capacity, oil grade, capacity chart and warning information sits in one place instead of spread across several dealer documents.
