Part No. 1307950GT 

 

Check the Hydraulic Oil Level 

 

Maintaining the hydraulic oil at the proper level is 
essential to machine operation. Improper hydraulic 
oil levels can damage hydraulic components. Daily 
checks allow the inspector to identify changes in 
oil level that might indicate the presence of 
hydraulic system problems. 

1

 

Be sure that the boom is in the stowed 
position. 

2

 

Visually inspect the sight gauge located on the 
side of the hydraulic oil tank. Add oil as 
needed. Do not overfill. 

 

Result: The hydraulic oil level should be at the 
FULL mark on the side of the hydraulic tank.
