Do you have a question about the Tigercat 855C and is the answer not in the manual?

Overview

The Tigercat 855C/L855C Feller Buncher is a heavy-duty forestry machine designed for efficient and safe tree felling operations. This service manual, issued in August 2008, provides comprehensive information for the maintenance, repair, and safe operation of these feller bunchers. The "C" in the model designation indicates a specific series or generation of the machine, while the "L" in L855C typically denotes a levelling feller buncher, distinguishing it from the standard 855C feller buncher. The serial numbers covered by this manual range from 85510101 to 85510500 for the 855C and 85520101 to 85520500 for the L855C. The fourth digit in the serial number differentiates between the standard feller buncher (1) and the levelling feller buncher (2), a distinction simplified in the manual by using an asterisk (e.g., 8550101 to 8550500) to indicate applicability to both types.

Function Description:

The primary function of the Tigercat 855C/L855C Feller Buncher is to efficiently cut down trees and gather them into bunches, preparing them for further processing like delimbing and skidding. This machine is equipped with a high-speed disc saw, which is crucial for its felling capability. The L855C variant, being a levelling feller buncher, offers enhanced stability and productivity on sloped terrain, allowing the operator to maintain a level cab and optimal cutting angle regardless of the ground conditions. This levelling capability significantly improves operator comfort, reduces fatigue, and increases productivity in challenging environments. The machine's robust design and powerful hydraulic system enable it to handle large trees and operate in demanding forestry applications.

Important Technical Specifications:

While specific detailed technical specifications like engine horsepower, hydraulic flow rates, or boom reach are not explicitly listed in the table of contents, the manual structure implies the presence of detailed information within its sections. Key areas covered include:

  • Hydraulic System/Load Sense: This section suggests a sophisticated hydraulic system that likely incorporates load-sensing technology. Load-sensing hydraulics optimize power distribution by only providing the necessary flow and pressure for the task at hand, leading to improved fuel efficiency, reduced heat generation, and extended component life.
  • Pilot System: The inclusion of a dedicated "Pilot System" section indicates that the machine utilizes a pilot-operated control system, which typically provides smooth, precise, and low-effort control of the machine's functions, enhancing operator comfort and control accuracy.
  • Electrical and Controls: This section would detail the machine's electrical architecture, wiring diagrams, and the various control modules and sensors that govern its operation.
  • Engine Start and Anti-Stall: These sections highlight the importance of the engine's starting procedures and its anti-stall features, which are critical for reliable operation and preventing engine shutdowns under heavy loads.
  • Oil Cooler, Radiator, and Cooling Fan: These components are vital for managing the operating temperatures of the engine and hydraulic system, ensuring optimal performance and preventing overheating, especially during continuous heavy-duty work.
  • Swing, Saw Drive, Wrist, and Clamps: These sections point to the mechanical and hydraulic systems responsible for the machine's core felling functions. The "Swing" mechanism allows the upper structure to rotate, positioning the felling head. The "Saw Drive" details the power transmission to the high-speed disc saw. "Wrist and Clamps" refer to the felling head's articulation and gripping mechanisms, which secure the tree during cutting and bunching.
  • Maximum Operating Mass: The "Notice of Certification" on page iv states that the operator enclosure is designed for machines with a maximum operating mass of 42200 Kg (93000 lb), providing a crucial parameter for the machine's structural integrity and safety.

Usage Features:

The Tigercat 855C/L855C Feller Buncher is designed with several features to enhance its usability and safety:

  • High-Speed Disc Saws: The manual emphasizes the safe use of high-speed disc saws, indicating that these are a core component of the felling head. High-speed disc saws offer fast and clean cuts, contributing to high productivity.
  • Controls and Operation: A dedicated section for "Controls and Operation" suggests an ergonomic and intuitive operator interface. The reference to a separate "Operator's Manual" for detailed operational procedures underscores the complexity and importance of proper machine handling.
  • Levelling (L855C): For the L855C, the levelling function is a significant usage feature, allowing the operator to maintain a horizontal cab position on slopes. This improves visibility, reduces operator fatigue, and enhances stability during felling operations.
  • Operator Enclosure Standards: The machine's operator enclosure meets stringent international and regional safety standards, including:
    • OREGON OSHA 437-007-0775:14a (TOPS - Tip-Over Protection Structures)
    • ISO 8084: 1993 (OPS - Operator Protection Structures)
    • ISO 8083: 1989 (FOPS - Falling Objects Protection Structures)
    • ISO 3411: 1995
    • ISO 2867: 1994
    • SAE J1356: FEB 1988
    • OREGON OSHA 437-007-0775:14b,c These certifications ensure a high level of operator safety against rollovers, falling objects, and penetrating objects, which are common hazards in forestry.
  • Trained Personnel Requirement: The manual explicitly states that "Only trained personnel should be allowed to operate or work on the machine," highlighting the need for skilled operators to ensure safe and efficient use.

Maintenance Features:

The service manual provides extensive guidance for maintaining the Tigercat 855C/L855C Feller Buncher, ensuring its longevity and optimal performance:

  • Lubrication and Maintenance Schedule: A dedicated section for "Lubrication and Maintenance" indicates a structured approach to routine servicing, likely including detailed lubrication points, fluid specifications, and maintenance intervals.
  • Troubleshooting and Repair Information: The various sections on specific systems (e.g., hydraulic, electrical, engine) imply detailed troubleshooting guides, repair procedures, and component-specific maintenance instructions.
  • Parts Catalog Reference: The availability of a "Parts Catalog" (Part No. 33295A) is crucial for identifying and ordering correct replacement parts, facilitating efficient repairs.
  • Safety Procedures for Servicing: The manual emphasizes safety throughout, with "WARNING" and "CAUTION" notices displayed where necessary, drawing attention to potential hazards during maintenance and repair procedures.
  • Strict Policy on Modifications: Tigercat maintains a strict policy against unauthorized modifications, stating that any changes not approved in writing by the Tigercat Engineering Manager or listed in official Tigercat documentation will void the certification of the operator enclosure and potentially the product warranty. This policy underscores the importance of maintaining the machine's original design integrity for safety and performance.
  • Updates and Revisions: Tigercat's commitment to providing updates on a regular basis and the instruction to contact the service department for discrepancies in information (especially for machines built after the manual's release date) ensure that users have access to the most current maintenance information.
  • Structural Integrity: The manual details that the mounting and frame/chassis to which the cab is attached are integral to the TOPS, FOPS, and OPS design, and any modifications or repairs to these protective structures must be done in consultation with the Tigercat Service department. This highlights the critical role of structural integrity in operator safety.

In summary, the Tigercat 855C/L855C Feller Buncher is a robust and sophisticated forestry machine designed for high-productivity felling operations, with a strong emphasis on operator safety and comprehensive maintenance support. The manual serves as an essential resource for ensuring the machine's safe, efficient, and long-lasting operation.
