Assembly
mWARNING! Before using the log splitter, review the
instructions below and all safety information. Failure to follow
these instructions may result in property damage or injury to
the operator or bystanders.
Splitting Operation + Additional Safety
Instructions
Follow these instructions to operate the log splitter:
1. Ensure all logs meet the proper size requirements
[(max log diameter: 8 inch (20.3 cm); max log length:
18 inch (46 cm); min log length: 13.5 inch (34.3 cm)].
IMPORTANT! Logs vary in hardness and structure. Small
logs with knots or harder wood may be more dicult to
split. Larger logs with less hardness may not be dicult to
split. Do not force the log splitter if the log fails to split on
the rst attempt.
8 in. (20.3 cm)
IMPORTANT! This product requires some assembly before
use. Due to the weight and/or size of the log splitter, it is
recommended that another adult be present to assist with the
assembly.
mCAUTION! Read and follow all instructions for assembly
and operation. Failure to properly assemble this log splitter
could result in serious injury to the user or bystanders, or
cause equipment damage.
Attaching the Handles
1. Insert the operating handles into the sockets on the
hydraulic pump (Fig. 1).
Fig. 1
Operating handle
Hydraulic pump
Socket
18 in. (46 cm)
2. When loading or positioning a log, always handle the bark
side; never handle the ends. Never place your hands or
body parts between the log and the splitter.
3. Never load or unload logs while the ram is moving.
4. Do not pile logs to be split in a place where you need to
reach across the splitter in order to load them.
5. Log ends need to be cut square (at a 90° angle) so that
they do not slide out when splitting and cause a safety
hazard, and so that they do not exert excessive force
on the log splitter components. Use a chain saw (not
included), like the Sun Joe® electric chain saws (models
SWJ698E, SWJ699E, SWJ700E, SWJ701E; visit snowjoe.
com to purchase online), to cut the logs ends square
before attempting to split them.
6. Never attempt to split more than one log at a time. A piece
of a log can unexpectedly be thrown from the machine,
which can result in severe personal injury.
7. Do not use if there is any indication of damage to the
hydraulic cylinder.
8. Do not use the splitter to split logs across the grain or
against the bark. Doing so will damage the log splitter and
could cause log pieces to be thrown, injuring the operator
or bystanders.

Page 6
mWARNING! Accidents occur when there is more than
one person involved in loading and operating the log splitter;
only one person should operate the splitter. If a second person
is assisting in loading the splitter, NEVER allow an assistant to
hold the log in place while the operator is using the unit.
Using the 10-Ton Log Splitter
1. Load the log lengthwise into the unit between the wedge
and the ram plate. Be sure that the split will be along
the grain.
2. Grip one handle in each hand and pump the handles back
and forth in opposite directions. This contrary motion will
force the log against the wedge (Fig. 2).
mDANGER! Always operate the unit from the side of the
operation handles, furthest from the wedge and the
splitting log.
Fig. 2
5. Turn the hand wheel clockwise until it is snug (Fig. 3). You
are now ready to split the next log.

3. Remove the split pieces.
4. Turn the hand wheel counterclockwise no more than one
full turn to relieve the pressure and retract the ram (Fig. 3).
mWARNING! NEVER attempt to remove a stuck log from
the splitter by forcing the use of the hydraulic ram to split the
log.
mWARNING! NEVER modify the log splitter.
Splitting a Short Log
This log splitter is designed to split logs between 13.5 inch
(34.3 cm) and 18 inch (46 cm) in length. When the log is
shorter than 13.5 inch, the ram plate may not be able to reach
the log. In this case, place a wood block with at surfaces in
front of the ram plate before operating (Fig. 4). Very short logs
may require an additional block.

NOTE: The block(s) used for extending the piston rod must be
at on all surfaces.
Maintenance
Removing a Jammed Log
If the log gets stuck on the wedge base, or the wedge
becomes embedded in the log and will not completely split or
separate from the log, follow the directions below to remove
the log:
1. Fully retract the ram.
2. Remove the jammed log from the wedge manually with a
pry bar.
mCAUTION! Be extremely careful as log pieces may y
o as they separate from the wedge.
3. Do not attempt to re-split a jammed log once it has been
removed from the wedge.
4. Manually split the log with a maul or cut it with a chain
saw.
Bleeding the Log Splitter
1. Extend the ram to its maximum length.
2. Remove the oil plug and make sure the oil level is full.
If needed, add more hydraulic oil to the hydraulic pump
(Fig. 4).
Fig. 4
Hand wheel
Oil plug
Piston rod
mWARNING! Periodically apply a light coat of rust-
resistant oil, such as 3-in-1 oil or WD-40, to the springs to
keep them in proper working order.
• Periodically check all fasteners for tightness.
• Annually clean and lightly lubricate parts.
• Use a glossy enamel spray paint to touch up scratched or
worn painted metal surfaces.
• Never exceed the load capacity rating of 10 tons; doing so
will damage the log splitter and void the manufacturer's
warranty.
IMPORTANT! If a part needs replacement, only use parts
that are specically recommended by the manufacturer.
Replacement parts that do not meet these specications
may result in a safety hazard, may compromise the tool's
performance, and will void the manufacturer's warranty.
Storage
• Before storing, make sure the log splitter is clean and dry.
Such upkeep is necessary to ensure years of trouble-free
performance.
• Make sure the ram is completely retracted prior to storing
the unit. Relieve any pressure by turning the hand wheel
counterclockwise, then retighten by turning the hand
wheel clockwise.
• Lightly lubricate all metal surfaces before storing.
• Store indoors or in a dry, protected area during severe
weather and during the winter months.
• Examine the log splitter thoroughly for worn, loose, or
damaged parts. Should you need to repair or replace a
part, contact an authorized Snow Joe® + Sun Joe® dealer
or call the Snow Joe® + Sun Joe® customer service center
at 1-866-SNOWJOE (1-866-766-9563) for assistance.

3. Turn the hand wheel counterclockwise as fast as possible.
The piston rod will retract into the hydraulic pump and
push the air out of the cylinder via the oil plug hole.
4. Check the oil level again, and if needed, add more
hydraulic oil.
5. Replace the oil plug and repeat steps 1-3 as needed.
6. To add oil, remove the oil plug and add oil to just below
the ll plug.
7. Replace the oil plug completely.
