R-H013-1108EN

3.5 Start Raking
Always switch off the tractor engine before you leave the tractor cab.
Make sure no persons are within a 25 meter radius of the Hibiscus during
operation.
Make sure no persons are near the Hibiscus when you engage the PTO.
Do not operate the Hibiscus without safety guards or swath curtain, or if
the safety guards or swath curtain are damaged.
Make sure no obstacles can be hit.
1. Operate the hydraulic system to lift the Hibiscus until the rakes are just
above the crop.
