2. Detailed Product Description

Overview

The S390 skid steer loader delivers a carefully balanced combination of compact footprint, reliable diesel performance, and versatile utility for light- to medium-duty tasks. Engineered for operators who require precise control and steady hydraulic power in constrained spaces, this model is well suited to landscaping, grounds maintenance, small-scale construction, agricultural support, and property management. As an EPA/ERUO5 emission-compliant unit, the S390 meets current regulatory expectations while offering efficient fuel use and dependable daily uptime.

Design and Structural Strength

The S390 is built around a compact, rigid frame that prioritizes structural durability without compromising maneuverability. At an operating weight of 1050 kg, the loader provides stable operation when handling rated loads of 200 kg and maximum loads up to 300 kg. The loader’s lift-arm geometry and frame reinforcement are configured to deliver consistent breakout force — rated at 3.5 kN — enabling the bucket and common attachments to penetrate, lift, and carry material with predictable control.

Powertrain, Emissions, and Fuel Efficiency

The S390 uses a single-cylinder, naturally aspirated diesel engine designed for simplicity and reliability. Its compliance with EPA/ERUO5 emission rules ensures the engine meets environmental standards required for many commercial and municipal projects. A compact 5 L fuel tank supports efficient operation for shorter shifts and minimizes downtime for refueling in tight jobsite conditions. The engine choice emphasizes low-maintenance operation and straightforward servicing routines that reduce total cost of ownership for small fleets.

Hydraulics and Working Performance

The working hydraulic system operates at a control pressure of 17 bar and is tuned to provide consistent arm and bucket response. The specified working cycle time for three primary movements is 9 seconds, reflecting balanced hydraulic flow and actuator sizing. This responsiveness helps operators complete repetitive tasks—such as loading, grading, and lifting—efficiently. The S390’s hydraulic design supports a high-flow configuration when required, increasing compatibility with hydraulic-driven attachments that demand greater flow and power.

Mobility and Traction

With a travel speed range of 0–6 km/h, the S390 emphasizes low-speed torque for controlled maneuvers rather than high transit speeds. The standard tire size of 23*8.5-12 provides a balanced footprint for traction on firm surfaces and minimal ground disturbance on soft surfaces. For customers who prefer track solutions for softer terrains or lower ground pressure, Shandong Woer Machinery offers customization options to match jobsite conditions—please consult sales for available conversions and specifications.

Operator Controls and Ergonomics

The S390’s operator station is designed for short-cycle comfort and intuitive control. Levers and pedals (where applicable) are arranged to minimize fatigue during repetitive operations. Visibility from the operator’s position is prioritized to ensure safe attachment use and improved situational awareness in congested worksites. Controls are straightforward for operators migrating from other mini loader skid steer models, shortening the learning curve and encouraging safer operation.

Attachment Compatibility and Versatility

A key advantage of the S390 is its compatibility with common skid steer attachments, such as buckets, pallet forks, augers, and hydraulic breakers. The high-flow hydraulic option broadens the range of supported tools, enabling more demanding hydraulic attachments. This versatility makes the S390 an efficient choice for contractors, landscapers, and rental operators who need one compact machine to perform a variety of tasks throughout the workday.

Maintenance, Serviceability, and Downtime Minimization

Serviceability is integral to the S390’s design. Routine access points for daily checks—fuel, hydraulic fluid, inspection points, and filters—are arranged to reduce inspection time and simplify maintenance tasks. The naturally aspirated engine reduces the number of peripheral systems requiring attention, and its straightforward layout supports rapid troubleshooting and repair when needed. Preventive maintenance practices recommended by Shandong Woer Machinery will help sustain performance and extend service intervals.

Safety Features

Safety considerations include stable lift-arm design, clear visibility lines, and robust guarding for hydraulic lines and critical linkages. Operators should follow local safety guidelines and standard operating procedures, including wearing personal protective equipment, performing pre-start inspections, and employing trained personnel for attachment changes. Shandong Woer Machinery emphasizes that proper training and adherence to load limits are central to safe operation.

Applications and Typical Use Cases

• Landscaping: precise grading, soil moving, and material handling in landscape construction.
• Small-scale construction: site cleanup, trench backfilling, and light excavation support.
• Agriculture and rural maintenance: fence-row clearing, feed distribution, and small hay handling jobs.
• Municipal and grounds maintenance: snow removal (with appropriate attachments), turf management, and waste loading.
• Rental fleets: compact footprint and attachment versatility make S390 suitable for rental operations serving homeowners and small contractors.
