Raising the Cab with Engine Running on Bobcat 763: Safe Operating Procedures

[MikePhua]

The user discussed the process of raising the cab on the Bobcat 763 skid steer loader while the engine is still running. Typically, raising the cab is done for routine inspections, maintenance, or repairs. However, ensuring safety and preventing damage to the machine or creating safety hazards is critical during this operation.
Safe Operating Steps for Raising the Cab

1. Ensure the Machine is on Level Ground
   Before raising the cab, make sure the machine is parked on a level surface. This helps prevent the machine from tilting or becoming unstable during the operation, ensuring the cab can be raised smoothly and without any external interference.
   
2. Lower All Unnecessary Attachments and Loads
   Before raising the cab, ensure that all attachments (such as buckets, forks, etc.) are placed in the lowest position, and that no loads are hanging. This reduces the pressure on the hydraulic system and ensures its stability, minimizing the risk of accidents during the process.
   
3. Start the Engine and Maintain Low RPM
   While raising the cab, the engine should be running, but it is important to maintain the engine at low RPMs. This helps control the hydraulic system's stability and prevents the hydraulic pressure from becoming unstable due to high engine speeds, ensuring safe operation.
   
4. Operate the Cab Raising Control Mechanism
   Following the instructions in the operator's manual, use the cab raising control (usually a hydraulic system) to slowly lift the cab. Ensure that the lever or button is operated smoothly and gradually, avoiding sudden movements that may pose safety risks.
   
5. Check and Ensure Hydraulic Connections are Secure
   During the cab lifting process, ensure that hydraulic hoses and connections are secure and free from leaks. If any issues are detected during the lift, stop the operation immediately to inspect and repair the system, preventing further damage to the hydraulics or safety concerns.
   
6. Ensure the Area Under and Around the Cab is Clear
   Before raising the cab, thoroughly check the area underneath and around the cab to make sure there are no obstructions. Any obstruction could interfere with the lifting process, potentially damaging the hydraulic system or causing safety hazards.
   
7. Maintain a Safe Distance from the Machine
   While the cab is being raised, the operator should maintain a safe distance and avoid standing directly beneath or too close to the machine. Keeping a safe distance reduces the risk of injury if something goes wrong during the operation.
   

Conclusion
Raising the cab on a Bobcat 763 skid steer loader with the engine running requires strict adherence to safety protocols. By ensuring the machine is on level ground, lowering unnecessary loads, maintaining low engine RPM, gradually raising the cab, checking hydraulic connections, and clearing the area, operators can minimize risks. Regular maintenance and inspections are key to ensuring safe operation.
