Front pump units - Turn the engine on and off in
short bursts without starting.

disengage the PTO while the engine is running.
3. Check the amount of oil in the tank. Add oil as required to
bring it to the proper level.
4. Run the engine at a slow idle. Stop the engine and then
check for hydraulic leaks. Make corrections before
