2. If a small amount of oil
remains in the crankcase
after the pump shuts off, the
adjusting screw should be
turned counterclockwise to
decrease the sensitivity of
the switch. DO NOT remove
the screw completely or
back it out so far as to
cause interference with the
replacement of the cover.
3. If the pump stays on
when no oil is flowing, the
adjusting screw should be
turned clockwise until the
pump shuts off.
1. The timing relay is factory
pre-set for a normal time
delay on most applications
(approximately 25 seconds).
3. To decrease the time setting,
turn the adjusting screw
counterclockwise. A fraction
of a turn will add or subtract
10-15 seconds of time.
2. To increase the time setting,
turn the adjusting screw
clockwise.

Servicing the Strainer:
The strainer should be
serviced daily under normal
operating conditions. If the
strainer becomes clogged or
partially blocked with engine
residue, the evacuation
operation will slow down due
to lack of oil flow to the pump.
1. Remove the strainer clean
out plug (Figure 7-1), and pull
the screen (Figure 7-2) out.
2. Wash the plug and screen in
clean fuel oil.
3. Place screen in plug counter
bore and replace assembly in
strainer housing. Tightening
plug wrench tight. Use
of pipe thread sealant is
recommended.
