Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact the skin.Be sure that the engine and components are cool enough to touch with your bare hand prior to performing any service work.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.
Personal injury can result from contact with refrigerant.Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury.Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.Personal injury or death can result from inhaling refrigerant through a lit cigarette.Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death.Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.
