4DR® RAPIDFIRE™ LOG SPLITTER
This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe
operation can create a number of hazards for you, as well as anyone else in the nearby area. Always take the following precautions
when using this machine:
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and
themselves.
Always wear protective goggles or safety glasses with side shields while using the Log Splitter to protect your eyes from
possible thrown debris.
Avoid wearing loose clothing or jewelry, which can catch on moving parts.
We recommend wearing gloves while using the Log Splitter. Be sure your gloves fit properly and do not have loose cuffs or
drawstrings.
Wear shoes with non-slip treads when using your Log Splitter. If you have safety shoes, we recommend wearing them. Do
not use the machine while barefoot or wearing open toed sandals.
Wear long pants while operating the Log Splitter.
Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.
Keep bystanders at least 50 feet away from your work area at all times. Stop the engine when another person or pet
approaches.
Protecting Yourself and Those Around You
Safety for Children and Pets
Towing
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.
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 secure the rack to the beam before towing.
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 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.

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.
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 or repairs.
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.

Chapter 3: Operating The DR RAPIDFIRE LOG SPLITTER
It may be helpful to better familiarize yourself with the features of your Log
Splitter by reviewing Figure 1 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 18).
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 “Rabbit” position.
5. Manual Start: Turn the Ignition Switch to the “On” position (Figure 19).
Grasp the recoil starter handle and slowly pull until you feel resistance
(Figure 17). 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. Electric Start: Turn and hold the Key in the “Start” position until Engine
starts then let the Key return to run position (Figure 19).
7. 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 18).
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, then advance the engine
throttle control to maximum speed.
Stopping the Engine
1. Move the Throttle Lever to Idle “Turtle” position (Figure 18).
2. Manual Start: Turn the Ignition Switch to the “Off” position (Figure 19).

correct or safe method of performing anything found in this manual,
please contact our Customer Service Representatives at our toll free
number: 1-800-DR-OWNER (376-9637).
When operating the Log Splitter, make sure you are standing in the safe
operating area (OPERATOR ZONE) as shown in Figure 17. You must stay
in the safe operating area at all times when the ram is in motion (whether
extending or retracting). Never place any part of your body into a position
that causes an unsafe operating condition.

Splitting
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.
1. Place the log on the Log Splitter. Grasp the log on the sides near the middle
of the block (Figure 23). Center the log, side-to-side, on the rail of the Log
Splitter, making sure that one end is against the Splitting Wedge.
Figure 20
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 20).
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.
Figure 21
Figure 22
The engagement Handle must be held fully forward against the hard stop
when splitting. Failure to do so may result in kickback of the Handle.
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 21).
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 22).
THE RAPIDFIRE LOG SPLITTER OPERATES DIFFERENTLY THAN A
HYDRAULIC SPLITTER. NOT OPERATING THE MACHINE PROPERLY WILL
RESULT IN DAMAGE TO THE MACHINE. ALWAYS FOLLOW THESE
NOTICES:
Do not be timid. A rapid movement of the Engagement Handle is
necessary for the Rack and Pinion to engage and disengage fully without
damage.
The Engagement Handle should never be stopped in any location
between the fully forward or fully backward positions.
Do not hold the Handle in the forward position when the Ram stops
moving forward. Always pull the Engagement Handle RAPIDLY to the
back (Auto-Retract) position as soon as the Log is split or when the Ram
is at the end of the stroke or when the Ram stops moving forward due to
a tough log.

14 DR® RAPIDFIRE™ LOG SPLITTER
2. With one hand, lift and hold the Safety Interlock Lever up, then RAPIDLY
press the Engagement Handle fully forward until it contacts the hard stop
and hold firmly until the Log is split (Figure 24).
3. IMMEDIATELY AFTER the log is split, pull and hold the Engagement Handle
to the Auto-Retract position to allow the Ram to return. If the Ram stops
before the end of the stroke while splitting a tough log, quickly pull the
Engagement Handle back to the Auto-Retract position.
Splitting Tough Logs
If the Ram stops before the end of the stroke while splitting a tough Log, quickly
pull the Engagement Handle back to the Auto-Retract position. Let the Ram
return and allow the Flywheels to gain momentum for another full power split.

Battery Care (electric start models)
Proper care can extend the life of a Battery. Follow these recommendations to
ensure your Battery’s best performance and long life:
Do not allow the Battery charge to get too low. If the machine is not used, charge the Battery every 4 – 6 weeks. Operate the
engine for at least 45 minutes to maintain proper Battery charge.
Store an unused Battery in a dry environment with temperatures between +40°F (+5°C) and +95°F (+35°C). Make sure the
storage temperatures will never be outside of these limits. The lower the storage temperature is within the specified
temperature, the better as the battery will discharge more slowly at low temperatures.
Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a
Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery
will read 12V-13.2V with a voltmeter.
Do not continue to crank your Engine when the Battery charge is low.
Charging the Battery
Operate the Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will need to use a
trickle charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts DC at no more than 2
amps.
At 1 amp the Battery may need to be charged for as long as 48 hours.
At 2 amps, the Battery may need to be charged for as long as 24 hours.
NOTE: Using the Recoil Starter and then running the Engine will not recharge a dead or significantly discharged Battery.
To connect a Battery Charger to your DR RAPIDFIRE LOG SPLITTER, follow the steps listed below.
1. Attach the Black (-) alligator clipped wire from the Charger Adapter to the Negative (-) terminal of the Battery, then attach the
Red (+) alligator clipped wire to the Positive (+) Battery terminal.
2. Plug the Charger into a standard wall outlet.
Typically, the Battery takes between 6 and 8 hours to fully charge. Do not leave the charger on the battery longer than
24 hours for a 2 amp charger, or 48 hours for a 1 amp charger as you could potentially damage the battery..
You can charge the Battery many times. The Battery lasts longer if you charge it before it is fully drained. Keep it fully
charged and at room temperature when not using your DR RAPIDFIRE LOG SPLITTER.
If the Battery does not hold its charge for very long under normal conditions or it simply won’t hold a charge, then
replace it. You can purchase replacement Batteries directly from us. To install your new Battery, follow the directions
on the previous page.
When you are finished charging the battery, disconnect the charger from the outlet first, then disconnect the battery charger wires
from the battery. If you leave the battery charger wires connected to the battery, the battery will discharge itself back into the
charger.
