Frequently Asked Questions

General

Q

What oil should I use?

A

We recommend KOHLER® oils for best performance. Other high-quality detergent oils, including synthetics, of American Petroleum Institute (API) service class SJ or higher are acceptable. Based on air temperatures at time of operation, oil type can vary. Refer to your owner’s manual for complete details.

Q

What type of fuel should I use?

A

Depending on the model, gas or diesel can be used. (Note: E15, E20 and E85 are NOT approved for use.)

Q

How should I store my generator or pump?

A

Long-term storage of your generator or pump requires preventative procedures to guard against deterioration. Disconnect any electrical devices. If the engine will be out of service for two months or more, follow these procedures:

  1. Add KOHLER PRO Series fuel treatment or equivalent to fuel tank. Run engine 2-3 minutes to get stabilized fuel into fuel system (failures due to untreated fuel are not warrantable).
  2. Change oil while engine is still warm from operation. Remove spark plug and pour about 1 oz. of engine oil into cylinder(s). Replace spark plug and crank engine slowly to distribute oil.
  3. Clean the generator or pump.
  4. Store covered in a clean, dry, well-ventilated area. When covering the generator or pump, do so only after engine and muffler/shield have completely cooled down. Generator or pump must remain in same position as normal operation.
Q

How long can my generator or pump run before I need to check the oil?

A

We recommend checking the oil level after every 5 hours of operation. Oil and filter change frequency and other routine maintenance varies per model, especially during periods of extended power outage. Check your owner’s manual for a complete list of required maintenance procedures and schedules.

Q

How do I clean my generator or pump?

A
  1. Make sure the generator or pump is turned off and is cool.
  2. Remove all dust and debris from around exhaust.
  3. Clean generator or pump, particularly alternator and engine air inlets and outlets, using a cloth and brush.
  4. Check general condition and replace any faulty parts.
Q

How should I transport my generator?

A

Before transporting, check that bolts are correctly tightened, close fuel valve and disconnect starter battery. Generator should be transported in its normal operating position; never lay it on its side.

Q

How should I transport my pump?

A

Before transporting, check that bolts are correctly tightened and close fuel valve. Pump should be transported in its normal operating position; never lay it on its side.

Q

What is GFCI?

A

Ground Fault Circuit Interrupter (GFCI) stops power to protected receptacles if a ground fault (electrical leak) is detected. If RESET button pops out, equipment plugged into receptacles may be faulty. If this happens, check equipment carefully. If equipment appears to be in good condition, press RESET button firmly until a click is heard. This will restore power. If RESET button pops out again, unplug equipment immediately. Contact your KOHLER Portable Generators dealer before attempting to use it again.

Q

How do I check the engine oil?

A
  1. Power off the generator or pump and let the engine sit for two minutes to settle the oil. Pull the dipstick from the back of the engine and wipe with a clean rag. Insert the dipstick back into the dipstick tube and pull it out. Note the crosshatching on the end of the dipstick, from “F” (Full) to
    “L” (Low), and see where the oil level falls. Add oil if the dipstick indicates that the oil level is low.
    (See What type of oil should I use?)
  2. Locate the yellow oil-access cap on the front of the engine (look for the oil can icon). Add a few ounces of oil, then recheck the oil level by inserting and removing the dipstick. Add oil until the level is near “F” Do not overfill the engine.
  3. When you’re finished adding oil, make sure the dipstick and oil access cap are securely in place. Push the AUTO button to place the generator or pump back in standby mode. If the utility power is still out, the generator or pump will start within three seconds. After the generator or pump starts, turn electric devices on when properly connected.
Q

Where is the oil dipstick?

A

The dipstick has a bright yellow ring attached to the end. The location varies by generator, but it’s typically easy to notice.

Q

How much oil does a generator or pump normally use?

A

The amount varies depending on engine model, length of time since last oil change, amount of power the generator is producing and length of power outage. Check your owner’s manual for a complete list of required maintenance procedures and schedules.

Q

What should I do if the generator is submerged in water?

A

Water and electricity are a very dangerous mix. If you can safely access the power switch or main line disconnect, power off the generator; if it continues to run while submerged, internal damage to both engine and generator will be significant. If you can’t safely access the power switch or main line disconnect, do not make any attempt to turn it off.
