Inspect the hydraulic filters if the hydraulic system on the Condor 60 manlift telescoping boom is acting sluggish and you already have checked the hydraulic oil to ensure it is not below the "low" level mark. Place the screwdriver tip on the bleed screw.
Unscrew the bleed screw on the filter head to allow the pressure in the return line to escape through the valve. Remove the old filter. Smear a layer of hydraulic fluid on the new filter's seal.
Place the new hydraulic filter inside the filter head, and hand-tighten. Rub the clean cloth at the top to remove excess hydraulic fluid. Turn the bleed screw until the valve is closed.
Start the Condor 60 manlift engine and check for leaks when operating the hydraulic system. If you notice a leak, turn off the machine and tighten the filter completely, using a filter wrench.
Check the oil in the torque hub if the wheels for the Condor 60 manlift move slowly without much force. Place a torque wench over each nut on the fill plug, and unscrew to remove.
Remove the nuts on the vent plug. Inspect the amount of oil inside the torque hub.
Pour oil into the tank slowly. Allow trapped air to rise to the surface and disperse. Continue to fill the tank to the halfway point with oil. Replace the vent plug and fill plug.
