Change the Filter
If the unit is equipped with a filter, check and change it at regular intervals. A dirty filter in a
pump will cause a slower delivery rate. Refer to the accessories section of your parts manual to
ensure that you replace the filter with one designed for your model. Always use a drip pan
directly below the filter when removing the cartridge to prevent contamination of the soil and
to aid in fluid recovery. Refer to item 2 in the parts list under
on
Power Reset External Adjustment

Turn adjustment screw in until reset motor starts.

tighten the lock nut.
