Kohler Command Pro Manuals
How do I fix an oil lock?
An oil lock occurs from tipping the machine or attempting to pull start an excessive amount of times. This causes the oil from the piston to move into the carburetor, preventing a spark that's required to start the engine.
To fix an oil lock:
1. Sit unit upright
2. Unscrew oil bolt in the back of the engine to drain the oil
3. Take off yellow oil caps with dipsticks
4. Unplug spark plug and wipe off any oil
5. Let the unit sit like this overnight, the oil will drain back into the cylinder
6. Screw the bolt back onto the back of the engine again, ensure the bolt is tightly fastened. Plug in the spark plug, and top up the oil and screw in the yellow caps
7. If the unit smokes upon start, it's burning off excess oil and will go away after a moment
What type of hydraulic fluid do I use with my OPS227/OPS232 Hydraulic Log Splitter?
We recommend using AW32/AW46 hydraulic fluid with your hydraulic log splitters.
