On the FRS, the crane must be in the stowed position when checking hydraulic
oil level. Hydraulic oil must be at operating temperature.
Step 1. Check the hydraulic oil level in sight glass (1) on hydraulic reservoir (2). Oil level should
be between add and full marks.
If oil level is low, add oil (Appendix G).
If oil level is OK, go to Step 2.
Step 2. Check that load is not over the load limit shown on the range diagram (Para 2-29). The crane
overload shutdown system prevents further lifting operations when the crane is overloaded.
If load is over maximum weight, lower load and reduce load to correct weight.
If load is OK, go to Step 3.
