Hydraulic Oil Change
Iron & Oak Commercial Products recommends an oil and filter change every 100 hours
of operation. Refer to the “Specifications” section, in this manual, for the type and quan-
tity of oil.
Important Notice
Never run the log splitter unless the hydraulic oil tank is full.
1
. Drain the head end of the cylinder.
a
. Remove the spark plug wire and spark
plug to help reduce the back pressure
on the engine and to prevent it from
starting.
b
. Disconnect return hose (1) from the oil
filter housing and place it in a waste oil
container. (Please properly dispose of
the waste oil per local regulations.)
c
. Extend the cylinder by holding the
valve handle forward and pulling on
the engine’s pull start cord until oil from
the return line stops flowing. This step
drains the head end of the cylinder.
2
. Drain the hydraulic tank.
a
. Place a waste oil container under inlet
hose (2).
b
. Remove the inlet hose from the pump.
c
. Slightly lower the front of the log splitter
to completely drain the tank.
3
. Remove and replace the oil filter.
a
. Remove the existing oil filter and prop-
erly dispose of it.
b
. Apply a thin coat of oil to the rubber
seal of the new oil filter.
c
. Screw the filter onto the filter head.
Once the filter makes contact with the
filter head, turn it an additional 3/4
turn. Hand-tighten only.
General Maintenance Check (before operating)
The hydraulic system (hoses, cylinder, and pump) should be carefully inspected before
each use. Also, inspect the mechanical parts at the same time. Make sure all clamps,
nuts, bolts, fittings, etc. are properly installed and tightened.
Do not check for leaks with your hand. Leaks can be located by pass-
ing a piece of cardboard or wood around the suspected leak and look-
ing for discoloration. High-pressure fluid escaping from a very small
hole can be almost invisible. Escaping fluid under pressure can have
sufficient force to penetrate skin, causing serious injury or even death.
If fluid is injected into your skin, it must be treated immediately by a doc-
tor familiar with this type of injury.
Always replace frayed, kinked, or cracked hoses and/or other damaged hydraulic com-
ponents with Iron & Oak Commercial Products authorized parts and components speci-
fied in the “Parts” section of this manual. Replacement parts from secondary suppliers
(not original Iron and Oak replacement parts) can lead to product damage and/or per-
sonal injury, and will void the warranty.
Do not remove the cap from the hydraulic tank or reservoir while the log
splitter is running. Hot oil, under pressure, could be expelled resulting
in serious injury.
Should it become necessary to loosen or remove any hydraulic fitting or line, be sure to
relieve all hydraulic pressure by shutting off the engine, removing spark plug wire, and
moving the valve control handle back and forth several times until no cylinder movement
is visible.
Engine Service
Refer to the engine manufacturers’ manual for engine maintenance and repair.
Storage
Between each use of the log splitter, we recommend applying a rust preventative (WD-40
or equivalent) to any bare metal areas on the top of the rail. This will assure the longest
possible service life of the wear pads.
Refer to the engine manufacturer's manual for engine storage.
