Maintenance and Care Guidelines for Grapple Machines

The reliability and service life of a grapple machine depend not only on its manufacturing quality but also on correct operation, maintenance and care by the user.

1. Diesel engine

Operate, maintain and service the diesel engine strictly according to the engine's operation and maintenance manual.

2. Key inspection and maintenance points

Regular inspection and timely maintenance are essential for productivity and a long service life. Observe the following points.

1. Before inspection or maintenance, park the machine on level ground, lower the working equipment and shut off the diesel engine.
2. Engage the pilot safety lock (disconnecting the pilot circuit) before starting maintenance.
3. Hydraulic oil is hot after operation. Do not disassemble components directly when checking levels or seals, refilling or draining. First shut off the engine and relieve the system pressure by operating the pilot control lever. Avoid touching oil lines to prevent burns.
4. The safety valve and overload valves of the hydraulic system are set at the factory and must not be adjusted arbitrarily, to prevent accidents.
5. Avoid maintenance on slopes, as the machine may move or slew under its own weight.
6. When installing or removing hydraulic components, keep dust and debris out of the hydraulic system. Do not damage the connection surfaces; repair any damage to restore their original precision.
7. Clean all fittings thoroughly before installation. Do not damage or leave out sealing rings, and install hoses without kinks.
8. Bolts on hydraulic and connecting pipes can loosen through impact and vibration. Inspect them regularly and tighten any loose bolts promptly.

3. Storage

Under suitable climatic conditions and with the measures above, the grapple machine can be stored for up to one year. After six months of storage, run all functions for 15 minutes without load and lubricate all components.
