BEAM AND SPLITTING WEDGE
Lubricate both sides of the beam where it contacts the
splitting wedge with engine oil before each use to
obtain years of service. However, normal wear will
occur. The wedge plate on the log splitter is designed
so the gibs on the side of the wedge plate can be eas­
ily 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 beam.
HDSE CLAMPS
Check the hose clamps on the suction hose (attached
to bottom of the pump) for proper tightness before
each use. Check the hose clamps on the return hose
at least once a season.
ENGINE
Refer to the separate engine manual for all engine
maintenance Instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every 25 hours under normal con­
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser­
viced. To service the air cleaner refer to the separate
^ engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom­
mended at the start of each season; check engine
manual for correct plug type and gap specification.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is essential to
engine performance and life. Be certain to remove all
dirt and combustible debris from muffler area.
FLEXIBLE PUMP COUPLER
The flexible pump coupler is a nylon “spider” insert,
located between the pump and engine shaft. The align­
ment is very critical. Over a period of time, the coupler
will harden and deteriorate. For a replacement flexible
pump coupler, order part number 717-0891.
IMPORTANT: Never hit the pump shaft in any
manner, as any blow will cause permanent dam­
age to the pump.
When replacing the flexible pump coupling, proceed
as follows.
1. Place the coupling half onto the engine shaft.
^ Make certain there is clearance between the cou­
pling half and the engine. Tighten the set screw.
2. Mount the pump onto the coupling support brack­
et. Tighten securely.
3. Carefully slide coupling half onto pump shaft
(make certain set screw is loose). Slide the key
into place on the shaft.
4. Install the nylon “spider” insert into coupling half
on the engine shaft.
5. Place the coupling shield in position on the hex
bolts. Rotate the keyway on the pump shaft so it
is toward the bottom.
6. Attach the coupling support bracket to the hex
bolts, carefully sliding the coupling half over the
“spider” insert. Secure coupling shield and cou­
pling support bracket with lock washers and hex
nuts. Tighten securely.
7. Adjust the two coupling halves (steel) so there is
between .010" and .060" clearance between the
two halves (at least the thickness of a matchbook
cover, up to 1/16" maximum). See figure 16.
Tighten the set screw in the coupling half on the
pump shaft.

PUMP
TIRE PRESSURE
Check sidewall of tire for manufacturer’s recommend­
ed maximum tire pressure. If this information does not
appear on your tire, maximum tire pressure under any
circumstances is 30 p.s.i. Equal pressure should be
maintained on both tires.
INSTALLATION OF TIRE TO RIM
A
WARNING: The following procedure must
be followed when removing or installing
a tire to the rim.
1. Be certain rim is clean and free of rust.
2. Lubricate both the tire and rim generously.
