Make certain to readjust the adjustment bolts so  
wedge moves freely, but no excess space exists  
between the wedge plate and the beam.  
Hose Clamps  
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.  
NOTE: Make certain proper clearance is obtained  
before tightening set screw.

Flexible Pump Coupler  
The flexible pump coupler is a nylon spiderinsert,  
located between the pump and the engine shaft. Over  
time, the coupler will harden and deteriorate.  
Clearance  
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.  
Engine  
IMPORTANT: Never hit the engine shaft in any manner,  
as a blow will cause permanent damage to the engine.

Tires  
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.  
See sidewall of tire for recommended pressure.  
Maximum tire pressure under any circumstances is 30  
p.s.i. Maintain equal pressure on all tires.  
WARNING: Excessive pressure (over 30  
p.s.i.) when seating beads may cause tire/rim  
assembly to burst with force sufficient to cause  
serious injury.

SECTION 7: STORING YOUR LOG SPLITTER  
Prepare your log splitter for storage at the end of the  
season or if the log splitter will not be used for 30 days  
or more.  
Drain fuel tank. Always drain fuel into approved  
container outdoors, away from open flame. Be sure  
that engine is cool before draining the fuel. Do not  
smoke while handling fuel.  
Start the engine and let it run until the fuel lines and  
carburetor are empty.  
Remove spark plug. Holding a rag over the cylinder  
hole, pour approximately 1/2 ounce (approximately  
one tablespoon) of engine oil into cylinder and  
crank slowly to distribute the oil.  
WARNING: Never store 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.  
Replace spark plug.  
Clean the log splitter thoroughly.  
Do not store gasoline from one season to another.  
Replace your gasoline can if it starts to rust. Rust  
and/or dirt in the gasoline will cause problems.  
Store unit in a clean, dry area. Do not store next to  
corrosive materials, such as fertilizer.  
NOTE: We do not recommend the use of pressure  
washers or garden hose to clean your unit. They may  
cause damage to electric components, spindles,  
pulleys, bearings or the engine. The use of water will  
result in shortened life and reduce serviceability.  
NOTE: If storing in an unventilated or metal storage  
shed, be certain to rustproof the equipment by coating  
with a light oil or silicone.  
Wipe unit with an oiled rag to prevent rust,  
especially on the wedge and the beam.
