15.13 Testing of safety valves 

 

Booms’ safety valves must be tested once every year. Lifespan of these safety valves is 30 
years and after that they must be changed to new valves. Follow the following steps when 
testing the valves:  
 

1. Drive the machine into transport position 
 
2. Switch on Drive mode from the selector switch in the upper control panel (picture 5, 
number 4) and test the function of all control levers (including the lower controls, if installed). 
Only the drive levers should work at this point.  
 
3. Switch the selector switch (upper control panel) to Outrigger position. Test the function of 
all control levers (including the lower controls, if installed). Only the outrigger levers should 
work at this point. 
 
4. Drive the outriggers to the ground and level the machine. The green light should be light 
as a signal for outriggers being set on the ground. If the green light does not light up, see 
section 15.7 (page 34). 
 
5. Switch the selector switch to Boom position (upper control panel). Test the function of all 
control levers (including lower controls, if installed). Only boom levers should work at this 
point, either in lower or upper control panel, depending on which is chosen. 
 
6. Remove the valve cap (K9

4) of the boom’s dump valve and keep the selector switch on 

boom position. Test the function of all control levers (including lower controls, if installed). 
None of the control levers should now work. 
 
7. 

Attach the unloading valve’s valve cap (K94) back to its place. The test is now complete. 

In case the functions were not as described, see directions below. 

 

In case the machine does not function as describe in steps 1-5 is the selector valve 
faulty (valve attached to coils K98A and K98B). In case the machine does not function 
as described in step 6, 

the booms’ dump valve is faulty (valve attached to coil K94). All 

faulty valves must be replaced with new valves before continuing operations on the 
machine.
