OPERATION & MAINTENANCE MANUAL STE35SR
External electron-magnetic interference may cause malfunction of the control system
controller, before installing a radio receiver or other wireless equipment, contact your
CFG distributor.
When working at the seashore, carefully clean the electric system to prevent corrosion.
When installing electrical equipment, connect it to the special power source connector.
Do not connect the optional power source to the fuse, starting switch, or battery relay.
Maintenance of Hydraulic System
The hydraulic device is in high temperature during and after operation. In addition, due to the
high pressure in the process of operation, the following matters should be noted during the
inspection and maintenance of the hydraulic device:
Leave the machine in a flat place so that the bucket is completely lowered to the ground, and
check and maintain it without pressure applied to the oil path of the cylinder.
Be sure to stop the engine
After the operation, the hydraulic oil and lubricating oil are still in the state of high temperature
and high pressure, and the maintenance can only be carried out after the oil temperature of
each part drops.
Sometimes even though the temperature has dropped, the internal pressure is still there. The
internal pressure should be released before maintenance. At the same time, slowly loosen the
screw plug, screw and screw loose pipe joint, avoid the front of the body, and remove it while
releasing internal pressure.
During the inspection and maintenance of the hydraulic oil circuit, please be sure to discharge
the air in the hydraulic tank and release the internal pressure.
Inspection and maintenance includes inspection of hydraulic oil level, filter and replacement of
hydraulic oil. When removing the high pressure hose, be careful not to damage the o-ring. If
there is any damage, please replace it.
When replacing and cleaning the filter element and screen of the hydraulic oil filter, when
repairing, replacing and removing the hydraulic piping of the hydraulic device, air shall be
discharged from the oil path.
Wear Parts
Replace wear parts such as the filter element or air cleaner element at the time of periodic
maintenance or before they reach the wear limit.
The wear parts should be replaced correctly in order to ensure more economic use of the
machine.
When ordering parts, check the part number in the parts catalog.
