GENERAL SAFETY RULES
WORK AREA
1. Keep the work area clean and well lit. Cluttered and dark areas invite accidents.
2. Do not operate the log splitter in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. The log splitter may create sparks which may ignite the
dust or fumes.
3. Keep children and bystanders away while operating the log splitter. Distractions can
cause you to lose control.
4. The surface must be perfectly level to prevent the machine from moving during operation.
ELECTRICAL SAFETY
1. The plug must match the outlet. Never modify the plug in any way. Unmodified plugs and
matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
3. Do not expose the log splitter to rain or wet conditions. Water entering a log splitter will
increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the log
splitter. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
5. When operating the log splitter outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
6. Do not leave the log splitter unattended when plugged in to the mains supply.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when operating a log
splitter. Do not use the log splitter while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while operating the log splitter may result
in serious personal injury.
2. Use safety equipment. Always wear eye protection. Safety equipment such as non-skid
safety shoes, close fitting clothing and suitable work gloves should always be used.
3. Avoid accidental starting. Ensure the switch is in the off position before plugging in.
4. Do not overreach. Keep proper footing and balance at all times. This enables better
control of the log splitter in unexpected situations.
5. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND/
OR SERIOUS INJURY. SAVE THESE INSTRUCTIONS.

USAGE AND CARE
1. Do not force the log splitter. It will do the job better and safer at the rate for which it was
designed.
2. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the log splitter. Such preventive safety measures reduce the risk of
starting the log splitter accidentally.
3. Store the log splitter out of the reach of children and do not allow persons unfamiliar with
the log splitter or these instructions to operate the log splitter. Log splitters are dangerous in
the hands of untrained users.
4. Maintain the log splitter. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the operation of the log splitter. If damaged,
have the log splitter repaired before use. Many accidents are caused by poorly
maintained power tools.
SERVICE
1. Have your log splitter serviced by a qualified repair person using only identical
replacement parts. This will ensure that safety is maintained.
ADDITIONAL SAFETY RULES FOR LOG BUSTERS
Extra special care is required when using this powerful tool to safeguard yourself and
that of others around you.
1. Never tamper with the log buster or attempt to operate the machine without covers
fitted.
2. Never work with the machine on the ground. This is not
only an uncomfortable working position but it can also
be dangerous because the operator has to bend
towards the machine, and thus risk being struck by chips
or debris.
3. The log buster must be used on a raised surface, of
sufficient height, so that the main bed of the machine is
at the same level as the extended arms of the operator,
4. Do not allow split logs to accumulate, always clean up
as you work, accumulated split logs and wood chips can create a hazardous work
environment.
5. The operator must operate the machines controls with both hands without using other
makeshift systems, i.e. wedging control levers down etc.
6. The machine must always be used by one operator only. Nobody must be allowed to use
the log buster unless they have read the instruction manual thoroughly and have been
instructed in its use. The machine must be used by adults only. Check that the logs to be
split are free from nails or wire, which may fly up or damage the machine. The ends of the
logs must be cut square. Branches must be cut off flush with the trunk.
7. Never attempt to split two logs at once; one may be ejected with possibly serious
damage.
8. Split wood in the direction of the grain. Do not attempt to split a piece of wood across the
grain as this could seriously damage the machine.

9. If the log moves away from the blade, retract the ram
and rotate the log through 90Oas shown on the right.
10. Do not attempt to load the log in the machine whilst the
log pusher is in motion.
11. Keep your hands well away from any splits and cracks
which open in the log.
12. Do not force the blade by pushing the log on the upper
part, as this can cause the blade to break or damage
the body of the machine. Always set the log on the
guides.
13. Never leave the machine unattended while it is running.
If you leave the machine, even for a short time,
disconnect from the power supply.
14. Never use the machine whilst under the influence of
alcohol, drugs, medicines, or when you are tired. A clear
mind is essential for safety.
15. Never request the assistance of another person to help you remove a jammed log.
16. Always disconnect the power cable when not in use, when carrying out maintenance
work or when moving the machine.
17. Never use the Log buster if it is not in perfect order or if it needs servicing.
18. Before starting work, check correct functioning of all the safety devices and check for
soundness of welded joints, securing nuts & bolts.
SIZE OF THE LOGS BEING SPLIT
The image on the right shows the MAXIMUM log size
that can be split.
• It is important not to attempt to split a log for
longer than 5 seconds as the pump may be
damaged by the oil overheating. This could
occur when the wood being split is excessively
fibrous, knotty or wet, green wood.
NOTE: The diameter of the log is indicative: i.e. A small log can be difficult to split if it
has knots or a particularly tough fibre.
• It is therefore better to stop and rotate the log by 90O, as shown above, to see
whether it can be split in a different plane.
• Not being able to split the log within this time, indicates that its hardness exceeds
the capacity of the machine and it should therefore be discarded so as not to
cause damage/injury.

BEFORE USE
BLEEDING THE HYDRAULIC SYSTEM
Before operating the log buster, the
Bleed Screw should be loosened by
2-3 turns until air can go in and out of
the oil tank smoothly.
• Air flow through the Bleed
Screw hole may be detectable
when the log buster is in
operation.
Before moving the log buster, make
sure the Bleed Screw is tightened to
avoid oil leaking from this point.
POSITIONING THE LOGS
• Always place the logs on the log retaining plates.
• Make sure the logs do not twist, rock or slip while being split.
• Do not force the log buster by
splitting the log on the upper
part of the wedge. This will
break the wedge or damage
the machine.
• Break log in the direction of its
grain.
• Do not place the log across the
log buster for splitting. It may be
dangerous and may seriously
damage the machine.
• Do not attempt to split 2 logs at the same time. One of them may fly
up and hit you.
WARNING: FAILURE TO DO THIS WILL CAUSE PERMANENT DAMAGE TO THE
LOG BUSTER.

OPERATION
OPERATING THE LOG BUSTER
This log buster is designed to be operated by one person only and requires
two handed operation by the user -
The left hand controls the hydraulic
control lever and the right hand
controls the push button switch.
1. Push and hold the push button
switch (1).
2. Then press and hold down the
control lever (2) to start the log
buster.
• The log buster will freeze if
either control is released.
• When both controls are
released, the log pusher returns
to the starting position.
NOTE: Once you start splitting the log, never reach into the splitting zone.
For extremely hard logs, rotate the log by 90° to see whether it can be split in a
different direction. In any case, if you are still not able to split the log, this
means that the wood exceeds the capacity of the machine and should be
discarded to protect the log buster.
ADJUSTING THE RETURN STOPPING POINT
If you are splitting a pile of shorter logs you may want to prevent the pusher
plate returning all the way back to the start, this will speed up future
operations.
To adjust how far the pusher plate comes back:
1. Extend the ram fully. as shown in “Operating the Log Buster” .
NOTE: Do not put any logs on the log splitter at this stage.
WARNING: NEVER FORCE THE LOG BUSTER FOR MORE THAN 5 SECONDS
TO SPLIT EXCESSIVELY HARD WOOD. AFTER THIS TIME, THE OIL UNDER
PRESSURE WILL OVERHEAT AND THE MACHINE COULD BE DAMAGED.

11
2. When the ram is at full extension,
release the push button switch.
• Keep the Control lever pressed
down the prevent the ram from
returning.
3. Loosen the handwheel on the
return stop and slide the stop to
the desired position
• Move the stop towards the
splitter to shorten the stroke.
4. Tighten the handwheel on the return stop to lock it into position.
5. Make sure youre hands are clear of the ram, and release the control lever.
• The ram should return as far as the stop will allow.
FREEING A JAMMED LOG
1. Release both controls.
• The log pusher moves back and completely stops at its starting
position.
2. Insert a wedge of wood under the
jammed log.
3. Start the log buster to push the
wedge under the jammed log.
4. Repeat above procedure with
sharper sloped wedges until the
log is completely free.
Do not try to hit the jammed log off of
the log buster, this may damage the
machine or may cause the log to fly
up and cause an accident.
