What is the recommended gas Charge PSI level for a Bobcat H880 Breaker, and CP RX2 and RX3 Breakers?

Electric furnace I assume- check with amp meter, if amps are below listed on breaker, replace the breaker, [check both the breakers in the furnace and in the house pannel, even if only one is tripping right now, the other(s) may start doing the same thing after you eliminate the weakest link- don't be surprised!] electric furnaces are notorius for "eating" breakers- they overheat the breakers for years then the breakers get weak and trip too easilly... if gas, post more info and I'll try to help further.

Low charge psi. Check for fault codes by holding head light button for 3 seconds.

Oil cooler on that machine is for hydraulic oil. Is your fault for engine oil psi or charge psi? Charge psi unlocks brakes. Premature engine oil breaking down check for fuel in engine oil through lift pump or injection pump.

You might post again describing the problem that you are having with the hammer. Enjoy

The high side psi. should be at least around 100# ps more than the low side psi. The low side psi sounds ok, but the high side tells you the problem is the outside condenser is plugging up! Go to an ac supply house,and buy a gallon of coil cleanner and dilute it and fully clean the outside condenser coils ,after it's cleaned ,check the charge now!

After considering the application work, determine the carrier on which the breaker will be installed. Gorilla Hammers has assigned a 'Recommended Carrier Weight' range to each breaker. If the operating weight of the carrier falls within this range, the carrier will safely handle this model of breaker. If the desired breaker falls outside of this recommended carrier weight range, the carriers lifting capacity and oil flow will need to be verified to ensure a proper fit. Lifting Capacity: Provided the weight of the breaker does not exceed the maximum lifting capacity at any position, the carrier is assumed to be stable. On most loader backhoes and excavators, the maximum lifting capacity is lowest when the boom is at full reach. This is the value that must be compared to the operating weight of the breaker. Oil Flow and Operating Pressure: A required oil flow range is specified for each breaker. Oil flow to the breaker within this range is adequate for operation. However, for maximum productivity the carrier should be capable of providing the maximum required flow. Compare the maximum oil flow requirement of the breaker with the oil flow capacity of the carrier. Remember the breaker operates at 1500-2500-psi. therefore, oil flow should be evaluated at operating pressure.

When breaking Concrete, the breaker is expected to penetrate the material, allowing it to crack and shake loose from the reinforcing steel. High frequency breakers tend to provide better performance in this application as it is not the energy per blow, but the fast blow rate that destroys the concrete's structural integrity. We recommend on concrete walls, footings, and floors to use a 750 - 1,500-ft. lb. breaker. With larger projects, consisting of large footings greater then 4 cu. yards, use a 2,000 - 5,000-ft. lb. breaker. The high production demand of bridge and building demolition requires a 7,500 - 10,000-ft. lb. breaker.

When breaking oversize material the breaker is expected to break the material down the middle into two pieces. This is optimum production. If the operator has to re-position the breaker towards the edge of the rock and gradually downsize the material, production rate slows down. To assess what size of breaker will effectively handle this application, the size and hardness of the material must be known. If a 4 cu. yard piece of hard rock (20,000 psi or greater) needs to be broken in half you will require a 7,500-ft. lb. or larger breaker. If a 2 cu .yd. piece of limestone (20,000 psi or less) needs to be broken in half you will require a 3,000 - 5,000-ft. lb. breaker.

When trenching, the breaker is expected to fracture a solid mass of rock into manageable pieces. The size of the material could be 100's of cu.yds, and the energy will be quickly absorbed. This is why it is recommended to work from a bench so the rock has somewhere to break out. We recommend when trenching in limestone or medium hard rock, to use a 3,000 - 5,000-ft. lb. breaker. When working in hard material we recommend a 7,500 - 10,000-ft.lb. breaker, and if high production is critical, a 13,500-ft.lb. breaker would be beneficial.
