The Bobcat 721 skid-steer loader uses a hydraulic system to power its lift arms, bucket, and other attachments. The hydraulic fluid in this system is essential for the proper operation of the machine, and using the wrong type of fluid can cause damage to the hydraulic components.
The recommended hydraulic fluid for the Bobcat 721 is a SAE 10W hydraulic oil. This type of oil has the correct viscosity for the 721's hydraulic system and will provide adequate protection for the hydraulic components.
Do not use any other type of hydraulic fluid in the Bobcat 721. Using the wrong type of fluid can cause damage to the hydraulic pump, hydraulic motor, and other hydraulic components.
It is also important to change the hydraulic fluid in the Bobcat 721 at regular intervals. The recommended change interval is every 1,000 hours of operation or once per year, whichever comes first.
Changing the hydraulic fluid will help to remove contaminants and moisture from the system and will help to extend the life of the hydraulic components.
