• Always operate the log splitter with all
safety equipment in place and all controls
properly adjusted for safe operation.
• Operate unit only when there is sufficient
light to clearly see work area.
• Operate unit only when standing in
operator zone. Unit stabilizers must be
extended before starting unit.
• Keep the operator zone and adjacent area
clear for safe, secure footing.
• Only one (1) person should operate the
logsplitter and load / unload logs.
• This unit is designed to be operated by
one person located in the operator zone.
• On ram-type log splitters on which the logs
are not cut square, the longest portion of
the log should be rotated down and the
most square end placed against the ram.
• Never attempt to split more than one (1)
log at a time unless the ram has been fully
extended and a second log is needed to
complete the separation of the first log.
• Use only your hand to operate the log
splitter controls.
• Use wheel chocks to prevent movement of
unit during operation.
• DO NOT operate in the rain or in wet or
damp locations.
• High fluid pressures are developed
in hydraulic log splitters. Pressurized
hydraulic fluid escaping through a pin hole
opening can puncture skin and cause
severe blood poisoning. Follow these
instructions at all times.
(a) Do not operate the unit with frayed,
kinked, cracked or damaged hoses,
fittings, or tubing.
(b) Stop the engine and relieve hydraulic
system pressure before changing or
adjusting fittings, hoses, tubing, or
other system components.
(c) Do not adjust the pressure settings of
the hydraulic pump or valve.
(d) Do not check for leaks with your hand.
Leaks can be located by passing
cardboard or wood over the suspected
