  Here are a few things to check if your crane isn't operating: * Ensure the parking brake is engaged. * Confirm the PTO is engaged. * Verify 12V power is reaching the radio receiver. If not, trace back to the power source, checking for blown fuses or loose ground connections. * Make sure the transmitter batteries are fully charged. Rechargeable batteries last about 11 months or 200 charges. * Ensure the hydraulic pump operates at its rated flow or GPMs, using a flow meter to check. If the pump seems weak, contact Stellar Customer Service.

Why does my stellar labs 4500 Construction Equipment crane only operate at full speed?

  If your crane only operates at full speed, check the following: * See if there is a constant 12V power supply to the proportional valve. If 12 volts are present without pulling the transmitter trigger, the handle/trigger assembly may be defective. If 8 volts are present at the proportional valve, the valve might be stuck open. Remove, clean, and reinstall the valve, being careful not to overtighten. If the problem continues, replace the proportional valve. * Ensure the manual override on the proportional valve is turned in, not out.

  If your crane operates manually but not electrically, check these items: * Ensure that there is 12V power going to the radio receiver. If there is no power going to the receiver, trace back to the power source and check for a blown fuse or loose ground connection. * Make sure that the parking brake is engaged. * Make sure that the parking brake switch is working properly. Check the parking brake switch by performing a continuity test. If the switch is defective, simply replace it.
