OPERATING INSTRUCTIONS
Read the ENTIRE IMPORTANT
SAFETY INFORMATION section
at the beginning of this manual
before use of this product.
The Splitting Operation - Additional
Safety Instructions:
1. Hold the bark side of logs when
loading or positioning, never the
ends. Never place your hands or any
body parts between a log and any
part of the Log Splitter.
2. Never load or unload logs while the
Ram (9) is moving.
3. Do not pile logs to be split in a place
that will make you reach across the
Log Splitter in order to load them.
4. Log ends that are not cut square can
slide out while splitting and cause
a safety hazard or cause excessive
force to Log Splitter components.
Use a chainsaw (not included) to
cut logs square on each end before
attempting to split them.
5. Never attempt to split more than
one log at a time. A piece of log can
Figure 1
Jack
Handles (3)
Socket
Ram (9)
SKU 62291 For technical questions, please call 1-888-866-5797. Page 6
unexpectedly be thrown from the
machine, causing severe personal
injury.
6. Do not use the Log Splitter to split
logs across the grain. Doing so will
damage the Log Splitter and could
also cause pieces of log to be thrown,
injuring the operator or bystanders.
Note: Many accidents occur when there is
more than one person involved in loading
and operating the Log Splitter. Only one
person should operate at a time. If a
second person is assisting in loading logs,
NEVER allow an assistant to hold the log
in place while the operator pulls on the
Jack Handles.
To Operate:
1. Grip one Handle in each hand and
pump the Handles in a back-and-forth
stroke motion. See Figure 2, below.
2. This action will force the log against
the Wedge Base and split the log.
3. Remove the split pieces.
4. Turn Handle Wheel (36A)
counterclockwise no more than one
full turn to retrieve the Ram. See
Figure 2.
5. Turn Handwheel clockwise until snug.
6. When finished, store the Log
Splitter with the Hand Wheel turned
counterclockwise one turn to relieve
the hydraulic pressure built up during
use.
To Remove A Stuck Log:
1. A log can be stuck on the Wedge
Base if the Wedge becomes
embedded in the log and the log
doesn’t completely split and separate.
This can happen if the log is too
stringy or tough to split completely.
If this happens, follow the directions
below.
2. WARNING! Never attempt to remove
a stuck log by doing the following:
• Using the hydraulic force of the Log
Splitter.
• Modifying the Log Splitter.
• Adding attachments to the Log
Splitter.
3. WARNING! Personal injury could
result from log or metal pieces flying
out at high speed toward the operator
or bystanders, or the Log Splitter
could become damaged.
4. Fully retract the Ram.
5. Remove the stuck log from the
Wedge manually with a pry bar.

6. IMPORTANT: Be extremely careful
as log pieces may fly off as they
separate from the Wedge.
7. Do not attempt to re-split a stuck log
once it has been removed from the
Wedge. Manually split with a maul,
or cut with a chainsaw.
WARNING! Remove Split Logs: Move
each split log away from the Log
Splitter. Split logs left near the Log
Splitter are a tripping hazard.
To Bleed the Log Splitter:
1. Extend Ram to its maximum length.
2. Remove the Oil Plug (6A) and top off
oil. See Figure 3, below.
3. Turn Handwheel counterclockwise as
fast as possible. Piston Rod (18A) will
retract into Ram and push air out of
Cylinder (23A) via Oil Plug hole. Top
off oil as needed.
4. Replace the Oil Plug and repeat
steps 1-3 as needed.
5. To add oil, remove the Oil Plug and
add oil to just below the Fill Plug.
Then Replace Oil Plug.

MAINTENANCE
TO PREVENT
SERIOUS INJURY
FROM EQUIPMENT FAILURE:
Do not use damaged
equipment. If abnormal noise
or vibration occurs, have the
problem corrected before
further use.
Many maintenance procedures,
including those not detailed
in this manual, will need to
be performed by a qualified
technician for safety.
If you have any doubts about
your ability to safely service
the Log Splitter, have a
qualified technician service the
equipment instead.
1. BEFORE EACH USE: Inspect the
Log Splitter and verify that there are
loose or damaged parts.
2. AFTER EACH USE: Wipe down
Log Splitter with a clean, soft cloth,
making sure to clean up any excess
or spilled hydraulic oil.
3. WHEN STORING: Retract the
Ram to and turn the Handwheel
counterclockwise by one turn to keep
the Hydraulic Cylinder Rod protected
from corrosion.
4. Store the Log Splitter in a clean, dry,
safe location away from children and
other unauthorized persons.
