• Gashåndtag: Controls engine speed and cutting wheel rotation.
• Bremsearm: The left brake handle simultaneously locks both tires for stability during operation.
• Chassis Lock Lever: This lever controls the locking and releasing of the chassis. When the chassis needs to rotate during work, lift the lever. To move the machine to the next work area, return the lever to its original position, and simultaneously release the tire brake handle to enable movement.
• Adjustable Upper Welding Push Rod: The front and back angle of the push rod can be adjusted by the handle to suit different operating scenarios.

Stump Grinding Process:

• Placering: Position the grinder so the cutting wheel is directly over the edge of the stump.
• Tyre Fixation: Engage the left brake handle to lock both tires, ensuring the machine remains stationary during grinding. This prevents collision injuries caused by operator errors and improves operational safety.
• Cutting Height and Depth: The SGR1500 features a 12-inch cutting height above ground and a 10-inch cutting depth below ground. Adjust the machine's position and angle to achieve the desired cutting depth.
• Swinging Chassis: Efter frigivelseasing the chassis lock, the chassis can be swung left and right to complete cutting work. This 65° swinging chassis allows for easy cutting of stumps up to 31.5 inches in diameter by simply swinging the chassis, enabling continuous and efficient operation.
• Slibning: Slowly lower the cutting wheel into the stump, moving it from side to side across the stump's surface. Take shallow passes to avoid overloading the engine.
• Rydning af affald: Periodically clear sawdust and wood chips from the cutting area to maintain visibility and prevent buildup.
