3. 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.
4. Loosen set screw on pump coupling half and remove coupling half.
5. 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 the end of the engine support bracket and
coupling half). Tighten set screw.
6. Install pump coupling half and key on pump shaft. Rotate coupling
half until set screw faces opening in shield. Do not tighten set
screw.
7. Install nylon “spider” onto engine coupling half.
8. 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.
9. Secure with nuts removed earlier.
10. Set.010” to.060” clearance/gap between the nylon “spider” and
the engine coupling half by sliding a feeler gauge or 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 5-2.
NOTE: Make certain proper clearance/gap is obtained before tightening set screw.

MAINTENANCE
Hydraulic Fluid and Inlet Filter
• Check the hydraulic fluid level in the log splitter reservoir tank
before each use. Maintain fluid level within the range specified on
the dipstick at all times.
• Change the hydraulic fluid in the reservoir every 100 hours of
operation. Follow the steps below:
1. Disconnect the suction hose from the bottom of the reservoir tank.
2. Carefully unthread the inlet filter and clean it with penetrating oil.
See Figure 5-2.
3. Allow the fluid to drain into a suitable container.
4. Reinsert the filter and refill the reservoir with three gallons of
oil. Approved fluids include Dexron® III / Mercon® III automatic
transmission fluid, a 10 Weight AW hydraulic oil or Pro-Mix™
AW-32 Hydraulic Oil.
• Maintain fluid level within the range specified on the dipstick at all
times.
NOTE: Always dispose of used hydraulic fluid and engine oil at
approved recycling centers only.
• Contaminants in fluid may damage the hydraulic components.
Flushing the reservoir tank and hoses with kerosene whenever
service is performed on the tank, hydraulic pump or valve is
recommended. Any repair to the hydraulic components should be
performed by a Sears Service Center.

Engine
Check Engine Oil
1. Stop engine and wait several minutes before checking oil level.
2. Remove oil fill dipstick.
3. Check oil level on dipstick. With engine on level ground, the oil
must be to FULL mark on dipstick.
4. Replace dipstick and tighten.
WARNING: Use extreme caution when working with
kerosene. It is an extremely flammable fluid.
Hydraulic Filter
• Change the hydraulic filter every 50 hours of operation. Use only a
10 micron hydraulic filter. Order part number 723-0405.
Beam and Splitting Wedge
• 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.
Changing Engine Oil
Only use high quality detergent oil rated with API service classification
SF, SG, or SH. Select the oil’s SAE viscosity grade according to the
expected operating temperature. Follow the chart below:
Colder
5W30
SAE 30
Warmer
