BOOM SWING
Swing cylinder does not move.
1. Check the operation of actuators other than of the
swing cylinder.
Determine if only the boom swing cylinder is faulty by
checking the operation of actuators for the devices
listed in the table on the right. If one of them is faulty,
check the main relief valve and the hydraulic pump
(main).
“5. Troubleshooting, Overall machine, All sys-
tems working, but insufficient force”
2. Check the spool operation.
• Spool stroke: 7 mm (0.3. in.)
• If the spool is sticking, try to take it out.
If it can’t be taken out or is scratched, replace the
housing block.
Note that the faulty spool operation could be
caused by the loosened bolt used for the return
spring.
