Performance Details:

Designed for efficient operation and ample torque for lifting and maneuvering loads up to 3500kg, 4000kg, and 4500kg respectively. Precise performance figures (HP, Torque) vary by specific engine variant.

Fuel System:

Typically Direct Injection Diesel with associated fuel filter and pump components.

Engine Cooling System:

Likely liquid-cooled system. Manual will detail coolant type, capacity, flushing intervals, and troubleshooting of the radiator, fan, and thermostat.

Emission Controls:

Details on any emission control systems, such as exhaust gas recirculation (EGR) or diesel oxidation catalysts (DOC), and their maintenance requirements.

Engine Diagnosis Codes:

If electronically controlled, the manual may cover diagnostic trouble codes (DTCs) and procedures for retrieving them.

Engine Filter Types:

Specifies types of engine filters including oil, fuel, and air filters, with replacement intervals and part numbers.

🔧 Transmission

Standard Transmission:

Likely a hydrostatic or torque converter automatic transmission, common for smooth operation and precise control in forklifts.

Optional Transmission:

While less common for forklifts, specialized configurations might exist. Primarily, the 'DS' variants might indicate specific dual-speed or enhanced drivetrain options.

Transmission Features:

Features for smooth acceleration, deceleration, and power delivery for lifting and driving. Includes drive axle, differential, and potentially braking system integration.

Transmission Fluid Type:

Specific type of transmission fluid (e.g., ATF, specialized hydraulic fluid) and its specifications will be provided.

📐 Dimensions

Exterior Dimensions:

Specific dimensions (length, width, height) vary based on mast configuration (e.g., duplex, triplex) and tire type. Capacities indicate the model series (3500kg, 4000kg, 4500kg).

Operating Weight:

Operating weight will vary based on exact configuration but typically falls within a substantial range for industrial forklifts of this capacity, designed for stability.
