4. PRE-OPERATION INSTRUCTIONS
4.1. HYDRAULIC FLUID
Check the tractor hydraulic fluid level and fill, if required.
4.2. INITIAL LOADER OPERATION
NOTE: If any loader cavitation is noticed during loader operation, check tractor hydraulic fluid level and
correct.
NOTE: Keep engine speed at low idle during the initial loader operation.
CAUTION: Escaping hydraulic fluid under
pressure can have sufficient force to
penetrate skin, causing serious personal
injury. Before disconnecting lines, be sure
to relieve all pressure. Before applying
pressure to system, be sure all connections
are tight and that lines, tubes, and hoses
are not damaged. Fluid escaping from a
very small hole can be almost invisible. Use
a piece of cardboard or wood, rather than
hands, to search for suspected leaks. If
injured by escaping fluid, see a doctor at
once. Serious infection or reaction can
develop if proper medical treatment is not
administered immediately.

4.3. EXTERNAL LOADER VALVE
CAUTION: When properly installed, the loader valve handle will control loader hydraulic circuits
as described below.

CAUTION: Do not tamper with relief valve setting. The relief valve is pre-set at the factory.
Changing the setting can cause overloading of the loader and tractor, which may result in serious
injury.
