ing this log splitter. Only the operator is to be near the log splitter during use.
ALWAYS operate the log splitter with a clear mind, free of the inuence of alcohol, drugs or medica-
tion.
ALWAYS wear close tted clothing, free from lanyards, strings or jewelry which could be an entrap-
ment hazard.
NEVER allow children to operate this log splitter. NEVER allow adults lacking proper instructions
and understanding to operate this log splitter.

NEVER place hands or feet between the log and splitting wedge during forward or reverse stroke.
Serious injury or death could result.
NEVER straddle or step over the log splitter during operation.
NEVER try to cross split a log. Always split with the grain.

e hydraulic system of your log splitter requires careful inspection along with the mechanical parts.
Be sure to replace frayed, kinked, cracked or otherwise damaged hydraulic hoses or hydraulic compo-
nents.
NEVER check for leaks of hydraulic uid with your hand. Fluid escaping from a small hole can be
almost invisible. Escaping uid under pressure can have sucient force to penetrate skin causing
SERIOUS INJURY or even DEATH. Leaks can be safely detected by passing a piece of cardboard over
the suspected leak and looking for discoloration.
NEVER remove the cap from the hydraulic tank or reservoir while the log splitter is running. e
tank could contain hot oil under pressure which could result in serious injury.
NEVER adjust the hydraulic valve. e pressure relief valve on your log splitter is preset at the facto-
ry. Only a qualied service technician should perform this adjustment.
A LWAYS seek professional medical attention immediately if injured by escaping hydraulic uid.
Serious infection or reaction can develop if proper medical treatment is not administered immediately.
A LWAYS be sure to relieve all pressure by shutting o the engine and moving the valve control han-
dle back and forth should it become necessary to loosen or remove any hydraulic tting.

NEVER operate your log splitter when it is in poor mechanical condition or in need of repair.
NEVER alter your log splitter in any manner. Such alterations may cause your log splitter to be un-
safe and will void the warranty.
NEVER tamper with the engine to run it at excessive speeds. e maximum engine speed is preset
by the manufacturer and is within safety limits. See Honda engine manual.
ALWAYS perform all recommended maintenance procedures BEFORE using your log splitter.
ALWAYS replace all damaged or worn parts IMMEDIATELY.
A LWAYS check the level of hydraulic oil and engine oil BEFORE operation.

NEVER operate your log splitter near a ame or spark. Hydraulic oil and gasoline are ammable and
can explode.
NEVER ll the gas tank while the engine is hot or running. Allow the engine to cool before refueling.
NEVER smoke while operating or refueling your log splitter. Gas fumes can easily explode.
A LWAYS replace the gas cap securely.
A LWAYS drain the fuel tank prior to storage to avoid the potential re hazard.
ONLY refuel your log splitter in a clear area with no gas fumes or spilled gas.
If gasoline has spilled, move the log splitter away from the area of the spill and avoid creating any
source of ignition until the spilled gas has evaporated.
NEVER store gasoline in the house or near a heating appliance.

A LWAYS turn the fuel shut o valve on the engine to the “OFF” position before towing the log
splitter. Failure to do so may result in ooding the engine.
IMPORTANT NOTE – (spark arrester):
As a precautionary measure against possible ying sparks, always take a Class B re extinguisher with
you when operating this log splitter in dry areas. is log splitter is equipped with an internal com-
bustion engine and should not be used on or near any unimproved forest-covered, brush-covered
or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting
applicable local or state laws (if any). If a spark arrester is used, it should be maintained in efective
working order by the operator. In the state of California, a spark arrester is required by law. Other
states have similar laws. Federal laws apply on federal lands. A spark arrester muer is optional and
available as an accessory at your nearest engine dealer. Always check the legal requirements in your
area.

NEVER allow anyone to sit or ride on your log splitter.
NEVER exceed 45 mph when towing your log splitter models with a solid axle (no springs) (28
PRO, PRO22C, PRO28C, PRO35C) and the Firewood Conveyor. Models with spring mounted axles
can be safely towed at posted highway speeds (28HO, 35HO, 28SHO, 35SHO). Adjust towing speed
for terrain and conditions. Be extra cautious when towing over rough terrain especially railroad
crossings.
A LWAYS check all local and state regulations regarding towing, licensing, and lights before towing
your log splitter.
ALWAYS check before towing to make sure that the log splitter is correctly and securely attached to
the towing vehicle and that the safety chains are secured to the hitch or bumper of the vehicle with
enough slack to allow turning. Always Class I, 2” ball with this log splitter.
A LWAYS be careful when backing up with your log splitter in tow. It could jackknife.
A LWAYS disconnect your log splitter from the towing vehicle before operating it.
A LWAYS turn the fuel shut o valve on the engine to the “OFF” position before towing the log
splitter. Failure to do so may result in ooding the engine and damaging engine oil.
MAKE SURE tires are fully inated and in good condition if you will be towing the
splitter. See tire sidewall for recommended tire pressure.
NEVER use the log splitter or rewood conveyor as a trailer to haul equipment, tools or wood.
All loose item should be removed before towing the equipment.
