Filling Reservoir
To add or replace oil in the cutter, retract blade completely. Loosen the reservoir
handle stop screw and remove the handle. Remove the reservoir plug and O-ring seal. Pull the stem of the reservoir
bladder out as far as possible. Add oil until it fills the stem. See "Compatible Hydraulic Fluids" section.
If the blade will not extend completely, and pumping becomes easier, it will generally be found that there is an
insufficient amount of oil in the compressor's hydraulic system. This trouble can also be caused by faulty pump
plunger packing or release valve packing by the pressure release valve being stuck open, or by foreign matter
preventing the release valve balls from seating properly. Faulty packing will usually be detected by excess oil leakage
around the pump plunger. A stuck valve ball can usually be freed by rapping the tool sharply.
Avoid damage to other parts in the process of rapping. Foreign matter can frequently
CAUTION
be flushed from a valve seat by pumping very rapidly with abrupt strokes.
If the blade will not retract completely, it will generally be found that there is too much oil in the cutter's hydraulic
system. Drain enough to permit complete retraction. If the blade will not retract and the oil reservoir is not full, the ram
is likely being held by a deformed washer.
A small amount of leakage is desirable around the ram; pump plunger, and pressure release valve plunger to
lubricate these parts. If enough leakage occurs to cause the oil to run, the packing should be replaced.
