Troubleshooting
IF THE ENGINE WILL NOT START:
1. Check the ensure switches are in the “ON” position.
2. Check engine oil level. The unit possesses a low oil shutdown feature that will not
allow your engine to start if the oil is below safe operating levels. This feature is installed to
increase the lie of your engine and prevent engine damage. If oil level is low, fill to the full mark
on dipstick. Refer to the Pre-Operating Instructions: Engine Oil Check section for exact oil type
and amounts.
3. Check the fuel level to ensure adequate fuel. Add fuel if necessary.
4. Remove and inspect the spark plug for cleanliness and proper electrode gap. If
needed, clean or replace the spark plug. Refer to Spark Plug Maintenance in the Maintenance
section of the Owner’s manual for proper procedure.
5. If the unit will still NOT start after performing the above checks, call our customer
service line at STANLEY®, Toll Free 1-877-684-8912 or take the unit to an authorized service
center.
NOTE:
Periodically, on the initial start-up or after the unit has been stored for a long period
of time, the float for your “Low Oil Shutdown” system will stick to the bottom of the oil pan.
Locate the two (2) wires to the low oil sensor diode (figure “Low Oil Sensor Diode” to the right)
located on the side of the engine block. Unplug these wires and,
only after ensuring the
engine is full of oil
, start the engine and allow it to run until warm (normally 20 minutes, as
this will heat the oil and release the float on the low oil shutdown system). Then, re-plug the
wires to the terminals on the low oil shutdown sending unit.
IF THE WATER PUMP WILL NOT PUMP:
1. Check if there is ample water in the pump chamber to fully prime the pump.
2. Check if the filter is clogged on the suction hose.
3. Check if the hose clamp is securely tightened.
4. Check if the water hose is damaged.
5. Check if suction height required for the application is too high. Refer to Product
Specifications section for unit maximum suction height.
6. If the water pump still will not pump water, call our Customer Service Hotline, Toll
Free 1-877-684-8912 or take the unit to an authorized service center.
