DOOSAN D20S-7 D25S-7 D30S-7 D33S-7 D35C-7 Forklift Operation and Maintenance Manual – SB2376E01 Download

Description

This Doosan D20S-7, D25S-7, D30S-7, D33S-7 and D35C-7 Operation and Maintenance Manual — publication SB2376E01 — is the complete English-language reference for the D25S-7 Series counterbalanced, combustion-engine lift trucks fitted with the D24A 2.4 litre diesel engine. It covers safe operation, daily checks, scheduled maintenance, capacities and every service interval from the first 50 hours through to 2,500 hours or 15 months. Whether you run a D20S-7 in a warehouse, a D30S-7 on a loading dock or a D35C-7 in heavy industry, this PDF gives the procedures, torque figures, fluid capacities and adjustment values the truck actually needs.

Safety Section

Every Doosan warning sign and label used across the truck is shown in place — operator restraint system, parking brake, mast and lift cylinder, load backrest, overhead guard, no-riders, moving fan and pressure warnings — together with general hazard information, mounting and dismounting rules, operating and maintenance cautions, and the full tipover avoidance and “How to Survive in a Tipover” procedures using the operator restraint system.

General Section

This section carries the Declaration of Conformity, the full machine specification table for the D20S-7 through D35C-7, noise and vibration data, and the pneumatic capacity charts both without and with sideshifter across single and double tyre, STD, FFL and FFT configurations up to 6,010 mm MFH masts. Serial number locations for the lift truck, D24A engine, powershift transmission, drive axle and side shifter are shown, along with the operator warning plate, identification plate and the mast, carriage and attachment abbreviation lists.

Operation Section

Operator station layout and monitoring systems are covered in detail — the full instrument panel (water-in-fuel, alternator, preheat, fuel level, coolant temperature, transmission oil temperature, MIL, seat belt, hour meter, parking brake and ECT fault lamps), the seat switch system, direction control lever, inching and brake pedals, lift, tilt and sideshift levers, parking brake, refuelling, pre-start walk-around, cold and warm D24A starting procedures, 12 V jump starting, power shift transmission operation, Electronic Controlled Transmission (ECT), Mono-Ped control, Auto Shift Controller ASC-100 and the Finger Tip option with its knobs, warning lamp and emergency switch. Operating techniques, load handling, turning, parking, fork adjustment, storage, shipping, lifting, tiedown and towing information close the section.

Maintenance Section

This is the largest section. It covers fork inspection, repair and rejection limits, tire inflation and shipping pressures, metric and imperial torque specifications, cooling system and fuel specifications, lubricant information, viscosity and refill capacity charts, and the full maintenance intervals schedule: when required, every 10 service hours or daily, first 50–100 hours, first 250 hours, every 250 hours or monthly, every 500 hours or 3 months, every 1,000 hours or 6 months, every 2,000 hours or yearly, and every 2,500 hours or 15 months. Each interval lists the service item, the check to be performed and the relevant torque, clearance or adjustment value.

D24A Engine and Truck Specifications at a Glance

The D25S-7 Series trucks are fitted with the D24A 2.4 litre, four-cylinder, four-cycle diesel engine rated 45.6 kW (62 hp) at 2,200 rpm with maximum torque of 262 N·m at 1,600 rpm. Transmission is a powershift unit with one forward and one reverse speed. Electrical system is 12 V with an 85 Ah battery. Rated capacities run from 2,000 kg on the D20S-7 at 500 mm load centre up to 3,500 kg on the D35C-7, with lift speeds, lowering speeds, drawbar pull, gradeability and service weights all listed in the specification table for each model.

Who This Manual Is For

Fleet managers, workshop technicians, service engineers and owner-operators of D20S-7 through D35C-7 trucks. It is also useful for training new operators, since the operation, safety and tipover sections read as a structured course.

Why This Doosan D25S-7 Series Manual Matters

Everything in this PDF is written for the truck in front of you. The capacity charts tell you what a D30S-7 can actually lift at a given mast height and load centre before the truck becomes unstable. The torque tables tell you what to tighten a wheel nut to on a D35C-7 and what to tighten the tilt cylinder clevis to on a D20S-7. The maintenance interval tables tell you exactly which components to inspect at every stage of the truck’s life and how often, so nothing gets skipped. The D24A DFC fault code table and ECT warning lamp flash codes let you diagnose engine and transmission faults without a laptop. And the tipover survival procedures are the difference between walking away from a rollover and being pinned.
