Hydraulic Oil Change - Iron & Oak BHH2099 Owner / Operator Use And Care Manual

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 raise 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.

4. Refill the hydraulic tank.
a. Reconnect inlet hose (2) to the pump.
b. Remove the hydraulic tank fill cap and
fill the tank with the recommended
type and quantity of oil. Replace the
cap.
5. Drain and refill the piston end of the
cylinder.
a. Hold the valve handle in the retract
position and pull the engine pull start
cord until the rod is fully retracted.
This step removes the old oil from the
piston end of the cylinder.
b. Reconnect return hose (1) to the oil
filter.
c. Extend the cylinder by holding the valve
handle forward and pulling on the
engine's pull start cord until the cylinder
is completely extended. This step refills
the piston end of the cylinder.
6. Start the engine and cycle the cylinder.
a. Replace the spark plug and spark plug
wire.
b. Start the engine and cycle the cylinder
several times.
c. Retract the cylinder and shut off the
engine.
d. Recheck the hydraulic tank to make
sure oil is filled within one inch from the
top of the tank.
