2.4. PTO SAFETY
• Never use a PTO driveline without a rotating shield in good working order.
• Ensure PTO driveline is securely attached at both ends before operating.
• Before starting tractor, turn power to PTO to the off position (where applicable).
• Keep body, hair, and clothing away from rotating PTO driveline.
• Ensure the PTO driveline shields turn freely on the PTO driveline.
• Do not exceed operating speed of 540 rpm.
• Keep u-joint angles small and equal. Do not exceed recommended operating
length for PTO driveline.
2.5. HYDRAULIC SAFETY
• Wear proper hand and face protection when searching for hydraulic leaks.
Escaping fluid under pressure can penetrate the skin, causing serious injury
like gangrene. In case of accident, see a doctor immediately.
• Fluid leaks in the hydraulic lift cylinders or hoses will allow the auger to lower
inadvertently. Repair all leaks and breaks immediately. Rupture could cause
damage and/or personal injury.
• A hydraulic lift is faster than a conventional hand crank—always clear area of
personnel before raising or lowering.
• Do not disconnect hydraulic couplers when hydraulic system is pressurized.
For the correct procedure, consult this manual or your tractor manual.
• Relieve pressure before unhooking hydraulic lines.
• Inspect hydraulic fittings and hoses for damage on a daily basis. Repair if
damaged.
• Ensure that the hydraulic line(s) is (are) properly connected and secure.
• Keep hydraulic line(s) away from moving parts.
• Clean connections before connecting to equipment.
