Protecting Yourself and Those Around You
Safety for Children and Pets
Hydraulic Safety
Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the
machine and the splitting activity.
Never assume that children will remain where you last saw them. Always follow these
precautions:
Keep children and pets at least 50 feet from the working area and ensure they are under the watchful care of a responsible
adult.
Be alert and turn the machine off if children or pets enter the work area.
Never allow children to operate the Log Splitter.
High fluid pressures are developed in hydraulic machines. Pressurized hydraulic fluid escaping through a pin hole opening can
puncture skin and cause severe blood poisoning. Therefore, the following Instructions should be heeded at all times.
Do not operate the unit with frayed, kinked, cracked or damaged hoses, fittings, or tubing. Stop the engine, wait 5 minutes
and relieve hydraulic system pressure by cycling the valve control lever from forward to reverse several times and returning to
neutral while engine is not running before changing or adjusting fittings, hoses, tubing, or other system components.
Do not change any Log Splitter relief valve settings. They are set at the factory for best Splitter performance and safety.
Do not check for leaks with your hand. Leaks can be located by passing cardboard or wood over the suspected area: Look for
discoloration. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical
treatment is not administered immediately.
Always wear safety glasses to protect your eyes from hydraulic fluid.
NEVER remove the cap from the hydraulic tank or reservoir while the log splitter is running. The tank could contain hot oil
under pressure which could result in serious injury.
This machine was built to be operated according to the safe operation practices in this manual. As with any type of power
equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of
amputating hands and feet and throwing debris. Failure to observe the following safety instructions could result in serious
injury or death.
Many accidents occur when more than one person operates the machine. No helper is allowed to assist with splitter controls
or handling the logs.

Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon
monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open
flame, and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank cap and
fuel container cap securely and Never remove gas cap while the engine is hot or running.
If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a fuel
container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it
away from the spark plug to prevent accidental starting, wait 5 minutes before making adjustments, repairs or refueling.
Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the
engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the
machine. If required, see your authorized dealer for engine governor adjustments.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create
a fire hazard. Do not use flammable solutions to clean the air filter.
The muffler and engine become very hot and can cause a severe burn; do not touch.
Safety with Gasoline - Powered Machines
Towing
ALWAYS check before towing to make certain your Splitter is correctly and securely attached to the towing vehicle. Be sure
that the ball hitch you are using is the proper size for the hitch coupler on the machine. Be sure the safety chains are properly
hooked to the vehicle leaving enough slack for turning.
Always use a Class I, 2” ball with this log splitter and replace the ball or coupler if damaged.
Always confirm coupler tightness each time before towing and after towing 50 miles.
ALWAYS use accessory lights and devices when transporting on a road or highway to warn operators of other vehicles. Check
your local government regulations for DOT information.
ALWAYS allow for added length of the Splitter when turning, parking, crossing intersections, and in all driving situations.
ALWAYS be careful when backing up. You could jackknife your Splitter if care is not taken.
NEVER exceed 45 mph. when towing your Splitter. Obey all state and local regulations when towing on state and local roads
and highways. Adjust your speed for terrain and conditions, as needed. Be extra cautious when towing over rough terrain,
especially over a railroad crossing.
NEVER allow anyone to sit or ride on your Splitter.
NEVER carry any cargo or wood on your Splitter.
Do travel slowly over rough terrain, on hillsides, and around curves to prevent tipping.
Do not tow the Splitter near the edge of a ditch or excavation.
ALWAYS turn the fuel shut off valve on the engine to the “OFF” position before towing the log splitter. Failure to do so may
result in flooding the engine.

SET UP
Adding Gas and Oil
Engine Oil See Engine Manual for specific Engine capacities and
specifications
Fuel Unleaded gasoline
NOTE: Use only the recommended high detergent engine oil. Other types of oil
could cause problems operating your machine. Please refer to your Engine
Owner’s Manual for detailed oil information.
Supplies Needed:
Clean Rag
Engine Oil
1. Position the machine so the Engine is level. Remove the Oil Fill/Dipstick
and clean the end of it with a rag (Figure 28).
2. Machines are shipped with no oil. Initially add 16 oz. of the oil
recommended by the Engine Manufacturer. Wait one minute for the oil to
settle.
3. Replace the Dipstick and screw it all the way in to ensure an accurate reading
and then remove it to check the oil level. The Oil is at the proper level when it
reaches the Full mark on the Dipstick (Figure 29). Clean the Dipstick with the
clean rag after checking.
4. Continue adding a few ounces of oil at a time, rechecking the Dipstick until
the oil reaches the Full mark. Be careful not to overfill.
5. Replace the Dipstick and screw all the way down when full.
6. Remove the Gas Fill Cap and fill the Gas Tank with fresh, unleaded gas (with
a minimum of 85 Octane) to approximately 1" to 1-1/2" below the top of the
fill neck to allow for fuel expansion (Figure 28). Be careful not to overfill.
Install the Gas Fill Cap before starting the engine. See your Engine Owner’s
Manual for more detailed information.
Note: To refill the gas tank, turn the engine OFF and let the engine cool at least five
minutes before removing the gas fill cap.

The Engine must be level to get an accurate reading when adjusting the
amount of oil. If the machine is not level, the oil level reading will not be
accurate and may cause engine damage.

16 DR® HORIZONTAL/VERTICAL LOG SPLITTER
Adding Hydraulic Fluid
Supplies Needed:
Paper Towels
Hydraulic Fluid (see Figure 30)
Note: Use the following instructions only when adding Fluid for the first time. Refer to the “Checking the Hydraulic Fluid Level” section
in Chapter 4 for information on maintaining the Hydraulic Fluid level.
Note: The Hydraulic Oil should be selected based on the outside temperature range
the Log Splitter will be used in. Refer to the chart provided to select the appropriate
Hydraulic Oil (Figure 30).
1. Remove the Reservoir Dipstick, which is located next to the engine on top of
the reservoir tank (Figure 31).
2. Slowly fill the Reservoir tank with the recommended Hydraulic Fluid until the
fluid reaches the Initial Fill Line on the Dipstick (Figure 32). Be Careful not to
overfill.
3. Replace the Dipstick in the Reservoir.
4. Make sure the Engine is in the “OFF” position (refer to Figure 37) and
disconnect the spark plug wire from the spark plug. Prime the pump by
pulling the recoil starter handle (refer to Figure 36) as far as it will go.
Repeat approximately 10 times.
5. Reconnect the spark plug wire and start the engine, following instructions in
Chapter 3.
6. Use the control handle to engage the wedge to the farthest extended
position. Then retract the wedge.
Note: Do not refill the tank to the Initial Fill Line. The fluid level has dropped since
the cylinder was cycled. Refilling to this line will overflow the tank. The proper level
for operation is when the fluid is about 1/4" above the bottom of the Dipstick.
7. Stop the Engine and recheck the fluid level. Add fluid as needed so that the
fluid Level is about 1/4" above the bottom of the dipstick (Figure 32).
Note: Failure to refill the tank to the Operating Level will void the splitter’s
warranty. Do not overfill. The proper level for operation is when the fluid is about
1/4" above the bottom of the Dipstick.
8. Restart the engine and extend and retract the wedge 12 complete cycles to
remove any trapped air in the system (the system is “self- bleeding”).
9. Stop the Engine and refill the tank as needed so the fluid is about 1/4"
above the bottom of the dipstick.

You must add hydraulic fluid before using the splitter. This machine is shipped without hydraulic fluid in the hydraulic
tank. When performing the following procedures, fill the hydraulic tank slowly, checking the level frequently to avoid
overfilling.
To get an accurate reading when checking the hydraulic fluid level:
- The machine should be on a level surface.
- The dipstick should be pushed in fully to ensure an accurate fluid level reading.
After the initial fill, much of the fluid will be drawn into the cylinder and hoses. Make certain the fluid is at the Operating
Level (Figure 32) to prevent damage to the hydraulic pump. DO NOT OVERFILL.

Lubricating the Beam
Supplies Needed:
Fluid Film
1. Lubricate the Beam area (where the splitting wedge will slide) with Fluid Film
(Figure 33). Do not use Grease.
Check the Tire Pressure
Tools Needed:
Tire Pressure Gauge
Air Compressor
1. Remove the Valve Stem Protective Cap and check the tire pressure with a Tire
Pressure Gauge (Figure 34).
2. Check what the manufacturers recommended pressure is that is stamped on
the side of the Tire.
3. If the pressure is too low, add air through the Valve Stem with an air hose.
4. Replace the Valve Stem Protective Cap when finished.

18 DR® HORIZONTAL/VERTICAL LOG SPLITTER
Chapter 3: Operating The DR HORIZONTAL/VERTICAL LOG SPLITTER
It may be helpful to better familiarize yourself with the features of your Log Splitter by reviewing Figure 2 in Chapter 2 before
beginning the steps outlined in this chapter.
Starting the Engine
Note: See the Engine Manual for more detailed and specific information on
operating the Engine.
1. Position your Log Splitter on flat, dry ground and chock the Wheels to
prevent the Splitter from moving during use.
2. Make sure the fuel shut-off valve is in the “ON” position (Figure 36).
3. Move the choke control lever to the CHOKE position to the left (should
only be needed if the engine is cold).
4. Move the throttle control lever to the FAST position.
5. Turn the Ignition Switch to the “On” position (Figure 37). Grasp the recoil
starter handle and slowly pull until you feel resistance (Figure 36). Let the
cord retract a little bit then pull the cord rapidly to start the engine. One or
two pulls usually starts the engine.
6. Move the choke control lever (if used for cold engine) slowly back to the
OPEN position (to the right) when the engine is running well (Figure 36).
Note: If the Log Splitter has not been running (cold engine), warm up the engine by
running the engine at half throttle for 3 to 4 minutes before splitting, then advance
the engine throttle control to maximum speed.
Stopping the Engine
1. Move the Throttle Lever to Idle position (Figure 36).
1. Turn the Ignition Switch to the “Off” position (Figure 37).

Handling Wood
Note: All logs should be no longer than 24". Use the following photos for the correct
and incorrect methods of splitting logs. Never split a log using an incorrect or
unsafe method.
Note: The Following Warnings and Instructions apply when Splitting Wood in both
the Horizontal and Vertical Positions.
Figure 40
Figure 39
Figure 38
Do not place your hands on the ends of the log when loading the Log
Splitter. This is a very UNSAFE method and could result in injury to your
hands (Figure 38).
Do not reach or step across the beam while the Log Splitter is running.
This is a very UNSAFE method which could cause personal injury or even
death.
Never attempt to split wood across the grain. The Log Splitter was not
designed for cross-grain splitting. Doing so could damage the Log
Splitter and may cause personal injury (Figure 39).
Make sure both ends of the log you are splitting are cut as square as
possible. This will prevent the log from sliding out of position while under
pressure (Figure 40).
When loading a log, always place your hands on the side of the log, not
on the ends, and never use your foot to help stabilize a log (Figure 41).
Failure to do so, may result in crushed or amputated fingers, toes, hand,
or foot.
When stabilizing log with left hand, remove your hand when the wedge
just contacts the log or serious injury may occur.
NEVER place hands or feet between the log and splitting wedge during
forward or reverse stroke as this could result in serious injury or death.
NEVER attempt to load the log splitter when the ram or wedge is in
motion.
Always keep fingers away from any cracks that open in the log while
splitting. They can quickly close and pinch or amputate your fingers.
Never attempt to remove partially split wood from the wedge with your
hands. Fully retract the wedge to dislodge wood with log dislodger.

20 DR® HORIZONTAL/VERTICAL LOG SPLITTER
Splitting Wood
The control handle has three positions:
FORWARD — Move the control handle forward to the FORWARD position to
move wedge toward the log to split (Figure 42).
Note: The control handle will return to the NEUTRAL position as soon as the handle
is released (from the FORWARD position only).
NEUTRAL — Release the control handle or move the lever to the NEUTRAL
position to stop the wedge movement (Figure 43).
REVERSE — Move the control handle back to the REVERSE position to return the
wedge toward the cylinder (Figure 44). The control handle returns to the
NEUTRAL position automatically when fully retracted.
Do not hold the handle in the REVERSE position when fully retracted.
Note: To stop the wedge before it is fully retracted when in the REVERSE position, the
handle must MANUALLY be put in the NEUTRAL position.
1. Start the engine as instructed in the “Starting the Engine” section in this
chapter.
2. Place the log on the Log Splitter. Grasp the log on the sides near the middle of
the log (Figure 45). Center the log, side-to-side, on the beam, making sure that
one end is against the end plate.
3. Using only your hand, push the Control Lever Forward. If the log moves before
it is contacted by the Wedge, release the Handle and reposition the log.
4. Hold the Control Lever, moving the Wedge towards the Log until the log is
split or the cylinder rod stops at its maximum travel position. Stop the Log
Splitter (forward movement), at any point in the splitting process, if you feel
an unsafe splitting condition is occurring. As the log is being split, DO NOT
reach forward and attempt to catch the split wood — let it fall.
5. Once the Wedge reaches its full forward travel, move the Control Lever to the
Reverse Position and the Wedge will return to the retracted position.
Never operate the Log Splitter unless the hydraulic fluid tank is at the proper
level.
