assembly (1).
2. Assemble the adaptor (R1/8) (3), threaded joint (4), cable (6) and
pressure gauge (5).
3. Start the engine and set the engine speed to maximum.
4. Set the hi-low dual speed switch Hi or Lo position and measure
the oil pressure.
5. If only the pressure in the clutch engaged position is low, check
the dual speed clutch system.
6. If the measurement is not within the factory specifications,
measure the system pressure, and adjust the system pressure
with relief valve (9) if necessary.
