not on the sideof a hill. Itcould tip, or rolling logs
or poor footing could cause an accident.
Operating the splitteron level ground also
prevents the spillage of gasoline from the fuel
tank.
• Never attempt to move the log splitter over hilly
or uneven terrain without a tow vehicle or
adequate help.
• Always block the wheels to prevent movement
of log splitter while in operation.
• Check the fuel before starting the engine.
Gasoline is an extremely flammable fuel. Do not
fill the gasoline tank indoors, when the engine is
running, or while the engine is still hot. Replace
gasoline cap securely and wipe off any spilled
gasoline before startingthe engine as it may
cause a fire or explosion.
• Both ends of each log must be cut as square as
possible to help prevent the log from riding out of
the splitter during operation.
Operation
• Vertical Operating Position: Stand infrontof
the logsplitter.
Horizontal Operating Position: Stand behind
the reservoirtank. See illustrations.
Know how to stop the unit and disengage the
controls.
Never place hands or feet between log and
splittingwedge or between log and end plate
during forward or reverse stroke. To do so may
result in crushed or amputated fingers or toes, or
worse, you may lose an arm or foot.
Do not straddle the splitter when using it. A slip
in any position could result in a serious injury.
Do not step over your log splitter when the
engine is running. You may trip or accidentally
activatethe splittingwedge if you step over.If
you need to get to the other side,walk around.
Never try to split two logs on top of each other.
One may fly out and injure you.
When loading the logsplitter, place your hands
on the side of the log, not at the ends. Never
attemptto load your splitter while the splitting
wedge is in motion. You may get caught by the
wedge and injured,
Only use your hand to operate the splitting
wedge or control lever, Never use your foot or a
rope or any other extensiondevice. This could
result in your inability to stopyour splitterquickly
enough to avoid injury.
Always keep fingers away from any cracks that
open in the log during splitting operation. They
can quickly close and pinch or amputate your
fingers.
• Never attemptto splitwoodsacross the grain.
Some types ofwood may burstor flyout ofyour
splitterand resultin injuryto you or a bystander.
• For logsthat are notcut square, the longest
portionofthe logshouldbe rotated downand
the most square end placed againstthe splitting
wedge.
• Keep your work area clean. Immediately
remove splitwoodaround yoursplittersothat
you do notstumble over it. Clean chipsand dirt
offend plate (wood platform)after each logis
split, orwhenever necessary to maintain flat
contact between wood and end plate (platform).
• Never move the togsplitterwhilethe engine is
