use. Replace the hydraulic oil seasonally according to
the chart below.
AIR TEMPERATURE

Below 32°F (0°C)
SAE5W2O*
*Use API Service Classification SE or CC.
Ingersoll Custom Blend motor oil is recommended.
This oil is a special blend for hydraulic applications.
The oil level must be kept 5” to 6” (120 mm to 150
mm) down from the top of the filler neck.
Use the following procedure to drain the hydraulic
system:
1. Remove the spark plug(s) from the engine.
2. Ground the spark plug wire(s) to the engine
block.
3. Place an oil drain pan with a capacity of two
gallons under the travel control valve.
4. Remove the 1/4” hex socket plug.
5. Crank the engine to “pump” the oil out the drain
hole.
6. Install the drain plug, spark plug(s) and wire(s).
7. Fill the reservoir to 5” to 6” (120 mm to 150 mm)
from the top of the filler neck.
8. Run the engine and (a) drive forward and
reverse a short distance and (b) raise and lower
the hydraulic lift two times. Check the oil level
again.
IMPORTANT:
Make sure oil reservoir is filled to
the proper level. Overfilling will
cause oil leakage. Under filling
will cause cavitation and
intermittent drive.
