kerosene whenever any repair work is performed 
on the tank, hydraulic pump or valve. For this job, 
contact your nearest service dealer. 

•

Change the hydraulic filter every 50 hours of 
operation. Use only a 10 micron hydraulic filter. 
Order part number 723-0405.

•

Lubricate both sides of the beam (where it comes 
into contact with the splitting wedge), before each 
use, with engine oil. The wedge plate on the log 
splitter is designed so the gibs on the side of the 
wedge plate can be removed and rotated and/or 
turned over for even wear.

•

Make certain to readjust the adjustment bolts so 
wedge moves freely, but no excess space exists 
between the wedge plate and the beam.

•

Check, before each use, if hose clamps on the 
suction hose (attached to the side of the pump) are 
tight. Check the hose clamps on the return hose at 
least once a season.

Refer to the engine manual for all maintenance needs.

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.

 Never hit the engine shaft in any manner, 

as a blow will cause permanent damage to the engine.

•

Remove three nuts and lock washers that secure 
the pump to the coupling shield. Two nuts are at the 
bottom corners and one is in the top center.

•

Remove the pump.

•

Rotate the engine by slowly pulling starter handle 
until engine coupling half set screw is visible. 
Loosen set screw using allen wrench and slide 
coupling half off engine shaft.

•

Loosen set screw on pump coupling half and 
remove coupling half.

•

Slide 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 end of the engine support bracket and 
coupling half). Tighten set screw.

•

Install pump coupling half and key on pump shaft. 
Rotate coupling half until set screw faces opening 
in shield. Do not tighten set screw.

•

Install nylon “spider” onto engine coupling half.

•

Align pump coupling half with nylon “spider” by 
rotating engine using starter handle. Slide coupling 
half into place while guiding three mounting bolts 
through holes in pump support bracket.

•

Secure with nuts and washers removed earlier.

•

Set .010” to .060” clearance between the nylon 
“spider” and the engine coupling half by sliding a 
matchbook cover between the nylon “spider” and 
the engine coupling half and moving pump coupling 
half as needed. Secure pump coupling half with set 
screw. See Figure 16.

NOTE:  Make certain proper clearance is obtained
before tightening set screw.

See sidewall of tire for recommended pressure. 
Maximum tire pressure under any circumstances is 30 
p.s.i. Maintain equal pressure on all tires. 

Excessive pressure (over 30 

p.s.i.) when seating beads may cause tire/rim 
assembly to burst with force sufficient to cause 
serious injury.
