Figure 1 and the corresponding table show the main
components of hand pump models P-141, P-142, P-
202, P-391, P-392, P-802, and P-842. The dual-
purpose vent/fill cap acts as a pressure relief valve in
case of accidental reservoir pressurization. To
provide an access port at the rear of the reservoir for
remote valves, use a return-to-tank kit. See the Table
1 for kit model numbers.

Figure 2 and the corresponding table below show the
main components of these hand pump models.
Model P-84 is equipped with a 4-way, 3-position
valve for use with double-acting cylinders. To convert
models P-18 or P-39 to foot operation, order Kit PC-10.

WARNING: These pumps are operated

with a non-vented reservoir. If the
reservoir is subjected to high pressure,
the casing may rupture, causing

personal injury and/or equipment damage.
NEVER attempt to return more oil to the reservoir
than it is capable of holding.
