Frequently Asked Questions about the Crane.
The PTO lever is located just under the ignition switch. Pressing or pulling the PTO lever will switch between crane and drive functions.
Moving the boom has to do with the fluid moving back and forth or extending and retracting within the boom cylinder. The movement that you see after you release the handle is the fluid leveling itself out between cylinders. It has no effect on the function of the crane and you will not lose any hook height. It is an optical illusion that is called hydraulic fluid balancing.
The winch rope is designed to withstand five times the lifting capacity of the boom, you should never lift anything that is heavier than the capacity of the crane. Refer to your weight chart decal for the maximum safe lifting capacity.
The levers are to be used only in a situation where the remote will not operate because of either the H.O.P. (Hydraulic Overload Protection) switch has been tripped or the remote's operation has been compromised. The reason for this is because the H.O.P. function only works through the remote control, by using the manual levers you are bypassing the safety standards designed to keep the boom from experiencing structural damage. Though you will still hear the audible alarm sound off, structural overload will not stop boom functions while using the manual levers.
The emergency stop on the side of the crane will not stop hydraulic operation, it will only shut down the electric functions of the remote control. You must still be able to move the crane from the ground in an emergency situation.
The serial numbers can be found on a silver tag attached to the side of the crane. Reference this number anytime you have a parts request or technical question, we at S.D.P. can only answer questions accurately based on the information we receive.
