TW-230DHB
This manual provides crucial information for the safe operation and maintenance of the Timberwolf TW 230DHB wood chipper. It stresses the importance of reading the manual to prevent injuries and equipment damage, and highlights the need for operator training in safe practices.
The Timberwolf TW 230DHB features a Kubota 4-cylinder diesel engine with a maximum power of 26kW (35hp). It is water-cooled, weighs 749kg, and has an 18-litre fuel capacity. The chipper can handle wood up to 160mm in diameter and process over 5 tonnes of brushwood per hour.
Operators must wear personal protective equipment and follow safety guidelines for transportation, hitching, and stabilizing the chipper. A safety exclusion zone of at least 10 meters should be maintained around the chipper.
Daily checks are required before starting. The manual provides instructions for engine operation, speed control, and discharge management. It also covers troubleshooting, blockage handling, and monitoring blade wear and hydraulic oil levels.
A service schedule outlines maintenance practices, including battery care and hazardous materials handling. Instructions for blade changes, drive belt tensioning, and component greasing are included.
The manual includes a warranty statement and an EC Declaration of Conformity, ensuring compliance with safety and environmental standards.
Parts locator diagrams, circuit diagrams, and a V-belt tensioning table assist with maintenance and troubleshooting.
Operators should maintain a safety exclusion zone, be aware of hazardous materials, and wear full protective gear. The chipper should never be left unattended while running.
Ensure adequate lighting, keep guards in place, avoid smoking during refueling, and ensure only trained individuals operate the machine. Ear protection is necessary due to noise levels exceeding 80dB.
Operators should wear a chainsaw safety helmet, work gloves, steel toe cap boots, and close-fitting clothing. Jewelry should be avoided.
Ensure secure connections when hitching the chipper to a vehicle. The maximum towing speed is 60 mph, and speed should be reduced on rough surfaces.
Perform maintenance and clean the chipper before storage. Store in a dry place and protect from rain. For long-term storage, additional tasks like rotating the engine shaft bi-weekly are required.
Ensure stability, secure guards, check fluid levels, inspect parts, and perform diagnostics before starting the machine.
The chipper has manual and auto controls for feed rollers. The red safety bar stops the rollers instantly when activated. The no-stress unit controls feed rate based on rotor speed.
Ensure the chipper is on firm ground, supported, and all safety guards are in place. Check for leaks and ensure the tow vehicle is isolated if hitched.
Starting the Engine: Set throttle to slow, insert key, and wait for the heater LED to go out before starting. Avoid engaging the starter for more than 20 seconds.
Stopping the Engine: Reduce speed to idle, let it run for a minute, then turn off the power and remove the key.
Feed wood up to the recommended diameter into the funnel. Use controls to manage rollers and monitor the discharge tube to prevent blockages.
Regularly check blade sharpness, hydraulic oil, and fuel levels. Follow safety practices during refueling and use genuine Timberwolf parts.
Guidance is provided for common issues like ejection problems and rotor jams, advising on obstruction checks and drive belt inspections.
Outlines daily checks and maintenance tasks at intervals of 50, 100, and 500 hours, or annually.
Consult authorized Timberwolf service agents for comprehensive maintenance and repairs to ensure optimal performance and safety.
The chipper has a maximum lift weight of 850kg. Regular checks on fasteners are necessary due to vibrations.
Store batteries upright in a cool, dry place. Disconnect the negative terminal first during installation and ensure good ventilation during charging.
Immobilize the engine before maintenance, handle blades with caution, and use lifting equipment for heavy components.
Follow safety procedures for handling and disposal of materials like engine oil and battery acid.
Disassemble using approved tools and PPE, separating recyclable materials.
Turn off the chipper, remove keys, and follow procedures to replace blades using genuine parts.
Adjust belt tension according to the V-Belt Tensioning Data Table and test the machine.
Drain old oil, replace the filter, and refill with VG 32 hydraulic oil.
Regularly grease the roller box slides and bearings, avoiding graphite-based products.
Timberwolf offers a 36-month warranty covering defects in materials and workmanship.
