CAUTION
In addition to the WARNINGs in this work package, observe the following for equipment
protection and care.
1.
Ensure all couplers are wiped clean before connection.

The auxiliary control valve must be in the OFF position when coupling or uncoupling rear hydraulic attachments. Failure
to do so may result in damage to the quick couplers and cause overheating of the hydraulic system.

not reverse circuit flow. This can cause damage to internal seals.
5.
Always keep critical attachment markings, such as warning stickers and tags legible.
