Hose Clamps
Check the clamps on the return hose before each
use and check the clamps on the suction hose once
a season.
Hydraulic Filter
Change the hydraulic filter every 50 hours of
operation. Use only a 10 micron hydraulic filter.
Order part number 723-0405.
Beam
Lubricate both sides of the beam (where it comes into
contact with the splitting wedge), before each use,
with engine oil.
Off-Season Storage
If the log splitter will not be used for more than 30
days, prepare it for storage as follows:
WARNING! Never store the machine
with fuel in the fuel tank inside of
building where fumes may reach an
open flame or spark, or where
ignition sources are present such as
hot water and space heaters,
furnaces, clothes dryers, stoves,
electric motors, etc.
1. Refer to the Engine Operator's manual
packed with your log splitter for information
on the off-season storage of the engine.
2. Clean the log splitter thoroughly.
NOTE: Using a pressure washer or garden
house to clean the log splitter is not
recommended. They may cause damage to
the bearings or the engine. The use of water
will result in a shortened life and reduce
serviceability.
3. Wipe the machine with an oiled rag to
prevent rust, especially on the wedge and
the beam.
4. Store the log splitter in a clean, dry area. Do
not store it next to corrosive materials, such
as fertilizer.
NOTE: If storing in an unventilated or metal
storage shed, be certain to rustproof the
equipment by coating it with a light oil or
silicone.

Flexible Pump Coupler
The flexible pump coupler is a nylon "spider" insert,
located between the pump and the engine shaft.
Over time, the coupler will harden and deteriorate.
Replace the coupler if you detect vibration or noise
coming from the area between the engine and
the pump. If the coupler fails completely, you will
experience a loss of power.
NOTE: On vertical shaft engines, it will be necessary
to remove the engine to access the hex screws
securing the pump to the engine shaft. Taking
the log splitter to an authorized service dealer is
recommended.
NOTE: Never hit the engine shaft in any manner,
as a blow will cause permanent damage to the
engine.
1. Disconnect the spark plug wire and ground
it against the engine.
2. Remove the three flange lock nuts and hex
screws that secure the pump to the coupling
Hex Screw
shield. Two flange lock nuts and hex screws
are at the bottom corners and one is in the
top center. See Figure 5-5

Flange Lock Nuts
3. Remove the pump.
4. Loosen the set screw on the pump coupling
half and remove the coupling half.
5. Rotate the engine by slowly pulling the
starter handle until the engine coupling half
set screw is at the bottom. Loosen the set
screw using an allen wrench and slide the
coupling half off the engine shaft.
6. Slide the new engine coupling half onto the
engine shaft until the end of the shaft is flush
with the inner portion of the coupling half.
(There must be space between the end of
the engine support bracket and the coupling
half). Tighten the set screw.

7. Install the nylon "spider" onto the engine
coupling half.
8. Install the pump coupling half and key on
the pump shaft. Rotate the coupling half
until the set screw faces down. Do not
tighten set screw.
9. Align the pump coupling half with the nylon
"spider" by rotating the engine using the
starter handle. Slide the coupling half into
place while guiding the three mounting
bolts through the holes in the pump support
bracket.
10. Secure with the nuts removed earlier.
11. Set .020" to .090" of a clearance/gap
between the nylon "spider" and the engine
coupling half by sliding a feeler gauge
between the nylon "spider" and the engine
coupling half and moving the pump
coupling half as needed. Install the set screw
and torque to 78 in-lbs to secure the pump
coupling half. See Figure 5-5.
NOTE: Make certain the proper clearance/
gap is obtained before tightening the set
screw.
12. Reconnect the spark plug.
