Hydraulic system air drainage
When starting the system for the first time and after changing the oil, the equipment can
only works with loads after eliminating all the air on the system, which is done as follows:
1. Check the oil level.
2. Place the control valve lever on a neutral position and turn the engine on for a
couple of minutes keeping a slow gear.
3. Increase the engine up to
1300 rpm (revolutions per minute)
and activate the
control valve lever from the neutral position to the two ends alternately, so that the
cylinder rods will be inside and outside the barrel but never reaching the maximum
course.
4. After 15 minutes of air draining, totally retreat the cylinder rods and fill up the
reservoir with oil.
5. When the air draining is well done, there will not be any noises on the hydraulic
system, no foam forming on the oil and the rods will work smoothly.
8. Maintenance
