3. The Drive Shaft (1) has a slot into which a
Flat Ke (40) is inserted. When the pump’sDrive Shaft (1) slides into the Coupling, the
Ke locks the pump’s Drive Shaft to the
Coupling.
Remove the Valve Blocks (26, 29) and put a4.few drops of oil in each of the openings sothat the gears do not eperience metal-to-
metal damage upon start up. This unit doesnot have an oil reservoir. Replace both Valve
Blocks.
Run an appropriate high-pressure line (not5.
included) from the outfeed of this pump to theinfeed of the Hdraulic Log Splitter such as a
4000 PSI hose with 1/2" ID. The outfeed portis located on top of the Back End Cap (22).
(See Fig.2.)
note: A few drops of oil must be placed in this
outfeed port before initial start up.
Run another high-pressure line (not included)6.from the outfeed port in the splitter to the
curved 90º elbow underneath the pump. (SeeFig. 2.)
If the unit is new and unused, this returna.hose should be lled with oil to prevent air
from getting into the sstem.Wig: Make sure the lever on the splitter
directs the circulating oil from the pump backto the pump and not the log splitter’s clinder
before the engine is started. Otherwise thesplitting blade will start moving immediatel.
MaIntenance & serVIcInGIn the event that the Pump must be removed1.from the log splitter, the rst task would be to
disconnect the hoses.
c m b i i a.i. A pan should be placed under thepump in order to catch dripping oil when
disconnecting the hoses.
