gasoline cap securely and wipe off any spilled
gasoline before startingthe engine as itmay
cause a fire or explosion.
Bothends of each log mustbe cut as square as
possibletohelp preventthe logfrom ridingoutof
the splitterduring operation.
Operation
Vertical Operating Position: Stand infrontof
the logsplitter.
Horizontal Operating Position: Stand behind
the reservoirtank. See illustrations.
• Know how tostop theunitand disengage the
controls.
•Never place handsor feet between logand
splittingwedge or between logand end plate
dudngforward or reverse stroke.To do so may
resultincrushed oramputatedfingers or toes, or
worse,you may losean armor foot.
•Do not straddlethe splitterwhen usingit.A slip
in any positioncould resultin a serious injury.
•Do notstep over yourlogsplitterwhen the
engine is running.You may tripor accidentally
activatethe splittingwedge ifyou stepover. If
you need to get totheotherside, walk around.
•Never tryto splittwo logsontop ofeach other.
One may fly out and injureyou.
•When loadingthe logsplitter,place yourhands
on the side ofthe log, notat the ends. Never
attemptto loadyoursplitterwhile thesplitting
wedge isin motion.You may get caughtbythe
wedge and injured.
•Only useyour handtooperate the splitting
wedge or controllever.Never use yourfoot or a
ropeor any other extensiondevice. Thiscould
resultinyour inabilitytostopyoursplitterquickly
enoughto avoid injury.
•Always keep fingers away from any cracksthat
open inthe log duringsplittingoperation.They
can quicklyclose and pinchor amputate your
fingers.
•Never attemptto splitwoods acrossthe grain.
Some types ofwood may burstor flyout ofyour
splitterand result ininjury toyou or abystander.

•For logsthat are not cutsquare, the longest
portionofthe logshouldbe rotateddownand
the most square end placed againstthe splitting
wedge.
•Keep your work area clean. Immediately
remove splitwood aroundyoursplittersothat
you do notstumble over it. Clean chipsand dirt
offend plate (wood platform)after each logis
