Loosen hose from fitting under hydraulic tank and allow tank to drain, reinstall hose to fitting. Fill tank with 20w - 50 motor oil to 1/4” to 1” below neck of tank and replace cap. Block up the rear of unit until wheels will rotate freely and start engine at a slow idle, move the motion control levers forward and run for several minutes. Stop engine and recheck oil level. If wheels don’t response an air lock has occured within the hydraulic system. Bleed air from lines, or let stand overnight to allow the air time to dissipate out of the oil. Retry responses & check the oil level. Note: Serious damage to the pumps and wheel motors can occur if the system is ran with an air lock. See the specification sheet for the correct kind of oil.
