GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1.
Keep your work area clean and well lit. Cluttered and dark areas invite
accidents.
2.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
3.
Keep bystanders, children, and visitors away while operating a splitter tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.

ELECTRICAL SAFETY
4.
Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
5.
Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way.
If the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates the need for the
three wire grounded power cord and grounded power supply system.
6.
Avoid body contact with grounded surfaces such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
7.
Do not expose splitter to rain or wet conditions. Water entering the splitter will
increase the risk of electric shock.
8.
Do not abuse the Power Cord. Never use the Power Cord to pull the Plug
from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or
moving parts. Replace damaged Power Cords immediately. Damaged Power
Cords increase the risk of electric shock.
9.
When operating the splitter outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
PERSONAL SAFETY
10.
Stay alert. Watch what you are doing, and use common sense when
operating the splitter. Do not use the splitter while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention while
operat ing the splitter may result in serious personal injury.
11.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
SKU 93815
PAGE 3
12.
Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Plugging in the splitter with the Power Switch on, invites accidents.
13.
Remove adjusting keys or wrenches before turning the splitter on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
14.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the splitter in unexpected
situations.
15.
Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
TOOL USE AND CARE
16.
Use clamps (not included) or other practical ways to secure and support
the workpiece to a stable platform. Holding the work by hand or against your
body is unstable and may lead to loss of control.
17.
Do not force the splitter. Use the correct splitter for your application. The
correct splitter will do the job better and safer at the rate for which it is designed.
18.
Do not use the power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
19.
Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the splitter. Such preventive
safety measures reduce the risk of starting the tool accidentally.
20.
Store idle splitter out of reach of children and other untrained persons.
The splitter is dangerous in the hands of untrained users.
21.
Maintain splitter with care. Keep cutting tools sharp and clean. Properly
maintained splitter with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged splitter. Tag damaged tools “Do not use” until
repaired.
22.
Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the splitter’s operation. If damaged, have
the splitter serviced before using. Many accidents are caused by poorly
maintained tools.

23.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
24.
Log Splitter service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could result in a risk
of injury.
25.
When servicing the Log Splitter, use only identical replacement parts.
Follow instructions in the “Inspection, Maintenance, And Cleaning” section
of this manual. Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
Using this poweful tool may create special hazards.
Take particular care to safeguard yourself and those around you.
Hydraulic systems. Never operate this tool if there is a hazard presented by hydraulic
fluid. Before using the Log Splitter, check for hydraulic leaks. Be sure the tool and your
work area are clean and free of oil spills. Hydraulic fluid can create hazards, causing you to
slip and fall, your hands to slip while using the machine, or fire hazard.
Electrical Safety. Never operate this tool if there is an electrical hazard. Never operate
an electrical tool in wet conditions. Never operate this tool with an improper electrical cord
or extension cord. Never operate this tool unless you are plugged into a properly grounded
outlet, which supplies 110-120Volts, and is protected by a 30 Amp circuit breaker.
Physical Hazards. Log Splitting creates special physical hazards. Never operate this
tool unless you are wearing proper safety gloves, hard-toed shoes, long pants and a shirt
with sleeves and ANSI-approved eye protection. Be careful of the splinters that will be
produced, to avoid puncture injury and potential jamming of the tool. Never try to split logs
which are too large or small to fit properly within the tool. Never attempt to split logs containing
nails, wire or other debris. Clean up as you work; accumulated split wood and wood chips
can create a hazardous work environment. Never continue to work in a cluttered work area
which may cause you to slip, trip or fall. Keep onlookers away from this tool, and never
allow unauthorized persons to operate this tool.

WARNING! Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain chemicals known (to the State of California)
to cause cancer, birth defects or other reproductive harm. Some examples of
these chemicals are: lead from lead-based paints, crystalline silica from bricks
and cement or other masonry products, arsenic and chromium from chemically
treated lumber. Your risk from these exposures varies, depending on how often
you do this type of work. To reduce your exposure to these chemicals: work in a
well ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
(California Health & Safety Code § 25249.5, et seq.)

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualfified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the tool.
Never remove the grounding prong from the plug. Do not use the tool if the
power cord or plug is damaged. If damaged, have it repaired by a service facility
before use. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric shock. (See Figure A.)
2.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure A.)
3.
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure A.)
Note: The Log
Splitter has a
3-prong electrical
plug.
FIGURE A
SKU 93815
PAGE 7
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4.
Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
5.
Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B.)
FIGURE B
EXTENSION CORDS
1.
Grounded tools require a three wire extension cord. Double Insulated tools
can use either a two or three wire extension cord.
2.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
3.
The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4.
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required.
(See Figure C.)
5.
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C.)
SKU 93815
PAGE 8
6.
If you are using an extension cord outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.

OPERATING INSTRUCTIONS
NOTE: For additional information regarding the parts listed in the following pages, refer
to the Assembly Diagram on page 15.
Please Refer to Figure D on page 10 in following these instructions.
1. Plan your work site. Work safely and save effort by planning your work before
hand. Have your logs positioned where they can be easily reached. Have a site
located to stack the split wood or load it onto a nearby truck or other carrier.
2.
Prepare the logs for splitting. This splitter accomodates logs up to 20” in length,
and 10” in diameter. When cutting up limbs and large sections, do not cut sections
any longer than 20”. Do not attempt to split green logs. Dry, seasoned logs split
much more easily, and will not jam as frequently as green wood.
3.
Route the power cord. Locate an appropriate power outlet, and secure an
adequate extension cord, if needed. Route the cord from the splitter to the power
source in a way that safeguards against tripping on the cord, or the cord becoming
damaged during the work session. Be sure to avoid wet conditions.
4.
Check level of hydraulic oil. Before first use, and before each subsequent use,
check to make sure the Log Splitter is filled with hydraulic oil (see “Checking/
Changing Hydraulic Oil” section on page 12).
5.
Position Splitter Securely. Be sure the Splitter is positioned firmly on level, solid
ground. If necessary, block the Wheels (25) with wedges to prevent them from
rolling.
6.
Open the Air Bleed. Loosen the Bleed Screw (14) - [located on the Front Cover
(15) in the upper right-hand corner] 3-4 turns whenever the splitter is being used.
Retighten this screw when you are finished.
7.
Place log onto Splitter. Place the log onto the splitter, lengthwise and lying flat on
the Main Body (47A). The log should lie flat on the Splitter, and be cradled by the
Guide (46A). Never attempt to split a log at an angle. Be sure the Wedge and Log
Pusher (49A) will contact the log squarely on the ends.
8.
Two hand operation. When it is safe to do so, depress the Switch (36) with one
hand. Wait a few seconds as the motor spins up and creates pressure in the
Hydraulic pump. Then, when it is safe to do so, depress the Handle A (61). The
Log Pusher (49A) will compress the log, pushing it against the Wedge, splitting the
log. Once the log is split, release both the Switch (36) and Handle A (61); this will
allow the Log Pusher (49A) to retract.
Warning: If the log does not split immediately, do not force it by maintaining the
thrust for more than a few seconds. This can damage the tool. It is better to try
re-positioning the log on the Log Splitter, or setting the log aside.
SKU 93815
PAGE 11
9.
Stack as you work. This will provide a safer work area, by keeping it uncluttered,
and avoid the danger of tripping, or damaging the power cord.
10.
Remember to retighten the Bleed Screw (14) when you are finished.
INSPECTION, MAINTENANCE, AND CLEANING
Note: Only a qualified service technician should repair or service the
internal hydraulic system of this unit.
1.
WARNING! Make sure the Switch (36) of the splitter is in its “OFF” position and
that the tool is unplugged from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
2.
BEFORE EACH USE, inspect the general condition of the splitter. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, and any other condition that may affect its safe
operation. If abnormal noise or vibration occurs, have the problem corrected
before further use. Do not use damaged equipment.
MAINTENANCE
WARNING: Before Performing Any Maintenance, Unplug the Tool from the Power Source!
CHECKING/CHANGING THE HYDRAULIC OIL
Please refer to Figure E on this page, and Parts Diagram on
page 15.
1. Make sure the LOG PUSHER (49A) is fully retracted.
2. Carefully unscrew the OIL GAUGE (10) and remove
it completely.
3. Position a container under the log splitter that will hold
at least 3.2 quarts of oil. Then tilt the machine to empty
the
oil into the container.
Figure E
4. Tilt the Log Splitter the other way, with the Oil Fill /
Oil Fill/Drain Port
Drain Port up. Using a clean funnel, pour in 3.2 quarts
of Hydraulic Oil. (Be sure to use only clean, high quality
hydraulic oil specifically made for this purpose.)
5. Clean the OIL GAUGE (10), and carefully insert it to make sure the oil level is
between the two marks on the dipstick.
6. Clean the OIL GAUGE (10), OIL SEAL (12), and O-RING OIL SEAL (11)
thoroughly, and re-install. Be careful not to damage the threads of the aluminum
FRONT COVER (15).
SKU 93815
PAGE 12
Warning: Be sure to dispose of the dirty oil properly. Take it to your local waste oil
recycling center. Never dump it on the ground or mix it with trash.
Refilling the Hydraulic Oil
1. Periodically check the level of the oil. It must be between the two notches on the
lower end of the Dip Stick. If the oil level is low, refill using a recommended oil.
Sharpening the Wedge
1. After long periods of operation, and when required; sharpen the wedge using a
fine-toothed file and carefully removing any burrs or flat spots on the edge.
HOW TO FREE A JAMMED LOG
1. Release both controls, so that the LOG PUSHER (49A) will be fully retracted.
2. Insert a triangular wedge of wood under the log, and activate the log pusher to push
the wedge under the jammed log.
3. Repeat this process using progressively larger wedges, until the jammed log is
freed. Warning: Never hammer on the jammed log, or place your hands near the log
when attempting to free it.
