Remember to stand to the side with the source
rod in the safe position. Use a screwdriver and
rag to remove debris form the sliding block
cavity.
Caution: Do not use your hand to clean this area.
Clean the sliding block and spring, add a thin layer of grease to
the sides, top, bottom, and angle of the block; reinstall. Make
sure the end of the spring is centered in the spring holding
support so the sliding block moves straight in and out.
Source Rod Bearings
1. The source rod bearings will need periodic
lubrication with MagnaLube. Indications of this
are difficulty in moving the rod up and down or
binding of the rod. Add MagnaLube to the swab
and swab the source rod at the point of entry
into the gauge.
Cleaning
Most of the gauge cleaning should be done with a mild
cleaner such as 409 or a citrus based cleaner like GooGone.
We do not recommend using fuels (gasoline or diesel) or oils to
clean the gauge as these chemicals can damage plastic,
rubber, and synthetic materials. If the aluminum gauge bottom
becomes coated with asphalt, WD-40 or GooGone will remove
the asphalt. Keep the liquefied asphalt away from the plastic
surfaces and gaskets. Be sure to wipe off residue before putting
the gauge back in use.
