Protecting Yourself and Those Around You
THIS IS A POWERFUL MACHINE. YOU MUST USE PROPER CLOTHING AND SAFETY GEAR WHEN
OPERATING THIS MACHINE TO PREVENT OR MINIMIZE THE RISK OF SEVERE INJURY. THIS MACHINE
CAN CUT AND SEVER PARTS OF YOUR BODY IF THEY BECOME CAUGHT BETWEEN THE RAM, LOG,
GUIDING PLATES AND/OR THE SPLITTING WEDGE. ALWAYS TAKE THE FOLLOWING PRECAUTIONS
WHEN OPERATING THIS MACHINE:
• ALWAYS WEAR PROTECTIVE GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHILE SPLITTING
WOOD TO PROTECT YOUR EYES FROM POSSIBLE THROWN BITS OF WOOD.
• WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR 4-TON ELECTRIC/HYDRAULIC DR WOOD
SPLITTER. IF YOU HAVE SAFETY SHOES, WE RECOMMEND WEARING THEM. DO NOT USE THE
MACHINE WHILE BAREFOOT OR WEARING OPEN SANDALS.
• AVOID WEARING LOOSE CLOTHING OR JEWELRY, WHICH CAN CATCH ON THE WOOD SPLITTER’S
MOVING PARTS.
• WE RECOMMEND WEARING GLOVES WHILE SPLITTING WOOD. BE SURE YOUR GLOVES FIT
PROPERLY AND DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS.
Operating the 4-TON ELECTRIC/HYDRAULIC DR WOOD SPLITTER Safely
THIS IS A POWERFUL MACHINE. YOU MUST OPERATE THE MACHINE SAFELY. UNSAFE OPERATION CAN
CREATE A NUMBER OF HAZARDS FOR YOU. ALWAYS TAKE THE FOLLOWING PRECAUTIONS WHEN
USING THIS MACHINE:
• NEVER ALLOW PEOPLE WHO ARE UNFAMILIAR WITH THESE INSTRUCTIONS TO USE THE 4-TON
ELECTRIC/HYDRAULIC DR WOOD SPLITTER.
• TO BE SAFE, DO NOT OPERATE THE MACHINE NEAR SMALL CHILDREN OR PETS, AND NEVER ALLOW
CHILDREN TO OPERATE THE WOOD SPLITTER. RETRACT THE RAM AND STOP THE MOTOR WHEN
ANOTHER PERSON OR PET APPROACHES.
• NEVER TEAM UP WITH ANOTHER PERSON TO OPERATE THE WOOD SPLITTER CONTROLS – THIS IS A
ONE PERSON JOB.
• KEEP YOUR HANDS AND FEET AWAY FROM THE SPLITTING AREA WHILE THE RAM IS IN MOTION.
• USE ONLY YOUR HANDS TO OPERATE THE WOOD SPLITTER CONTROLS.
• DO NOT PLACE YOUR HANDS AT PINCH POINTS WHERE THEY CAN CATCH BETWEEN A LOG AND
THE WEDGE, LOG GUIDING PLATES OR THE RAM.
• DO NOT PUT ANY PART OF YOURSELF, YOUR CLOTHING, OR YOUR PERSONAL PROTECTIVE
EQUIPMENT INTO A CRACK IN A LOG THAT YOU ARE SPLITTING; IT MIGHT CLOSE SUDDENLY WITH
GREAT FORCE.
• NEVER SPLIT ANYTHING OTHER THAN LOGS FREE OF NAILS, WIRES, AND BRANCHES. MAXIMUM
LOG LENGTH IS 20" WITH A MAXIMUM DIAMETER OF 10" FOR THE DR 4-TON WOOD SPLITTER.
NOTE: The log diameter does not necessarily indicate the difficulty of the split. A small diameter log can be difficult to
split if it has knots or its fiber is very tough, whereas you can split a larger log easily if its fiber is smooth and loose.
4 WDS 4.4, 4-TON ELECTRIC/HYDRAULIC DR® WOOD SPLITTER
• NEVER OPERATE THE WOOD SPLITTER IN AN AREA OF NATURAL GAS OR FLAMMABLE LIQUIDS.

Safety with Electric-Powered Machines
NEVER OVERLOOK THE HAZARDS OF ELECTRICITY. ALWAYS FOLLOW THESE PRECAUTIONS:
•
NEVER OPEN THE SWITCH BOX OR MOTOR COVER. NEVER ATTEMPT ANY ELECTRICAL REPAIRS
YOURSELF. IF IN DOUBT, CONSULT A QUALIFIED ELECTRICIAN, VISIT OUR WEBSITE AT
WWW.DRPOWER.COM OR CONTACT DR POWER EQUIPMENT FOR TOLL-FREE SUPPORT AT:
1-800-DR-OWNER (376-9637) FOR HELP OR INFORMATION.
• NEVER OPERATE THE WOOD SPLITTER IF THERE IS AN ELECTRICAL HAZARD PRESENT.
• NEVER OPERATE THE WOOD SPLITTER IN WET CONDITIONS.
• NEVER OPERATE THE WOOD SPLITTER WITH A DAMAGED ELECTRICAL CORD OR DAMAGED
EXTENSION CORD.
• NEVER PULL ON THE ELECTRICAL CORD TO MOVE THE MACHINE.
• ALWAYS GRASP THE ELECTRICAL CORD PLUG WHEN UNPLUGGING THE CORD FROM THE OUTLET;
NEVER PULL THE PLUG OUT BY THE CORD.
• NEVER OPERATE THE WOOD SPLITTER UNLESS THE ELECTRICAL CORD IS PLUGGED INTO A
PROPERLY GROUNDED OUTLET, WHICH SUPPLIES 110-120V POWER, AND IS PROTECTED BY A 15-AMP
CIRCUIT BREAKER.
• NEVER TAMPER WITH SAFETY DEVICES. CHECK THEIR PROPER OPERATION REGULARLY.
• IF YOU WILL USE AN EXTENSION CORD, KEEP THE CONNECTION BETWEEN THE ELECTRICAL CORD
AND THE EXTENSION CORD WELL AWAY FROM ANY WATER.
• NEVER USE AN EXTENSION CORD LONGER THAN 25 FEET AND SMALLER THAN 12 AWG IN
DIAMETER, OR LONGER THAN 50 FEET AND SMALLER THAN 10 AWG IN DIAMETER; THE CORD WILL
PRODUCE A VOLTAGE DROP THAT WILL PREVENT THE MOTOR FROM SUPPLYING FULL POWER AND
MAY CAUSE DAMAGE TO THE MOTOR.
• ALWAYS KEEP THE ELECTRICAL CORD AND/OR EXTENSION CORD AWAY FROM EXCESSIVE HEAT, OIL,
AND SHARP OBJECTS.

Hydraulic Safety
ESCAPING PRESSURIZED FLUID FROM HYDRAULIC SYSTEM LEAKS CAN HAVE ENOUGH FORCE TO
PENETRATE SKIN AND CAUSE SERIOUS INJURY OR DEATH. HYDRAULIC FLUID CAN REMAIN
PRESSURIZED WHILE THE MOTOR IS OFF DUE TO THE RETURN SPRING FORCE ON THE RAM. ALWAYS
FOLLOW THESE PRECAUTIONS:
• ALWAYS RELEASE RESIDUAL ENERGY FROM PRESSURIZED HYDRAULIC FLUID AND ALLOW THE FLUID
TO COOL BEFORE DOING ANY MAINTENANCE OR REPAIR WORK ON THE WOOD SPLITTER.
• PLEASE FOLLOW THESE STEPS TO DEPRESSURIZE THE SYSTEM AND RELEASE RESIDUAL HYDRAULIC
ENERGY BEFORE STARTING ANY REPAIRS.
- UNPLUG THE WOOD SPLITTER FROM THE POWER SOURCE.
- MOVE THE OPERATING HANDLE DOWN AND UP FROM ONE LIMIT OF TRAVEL TO THE OTHER AT
LEAST FOUR TIMES. HOLD THE HANDLE FOR THREE SECONDS AT EACH LIMIT OF TRAVEL. THE
RAM SHOULD NOT MOVE DURING THE 4TH CYCLE AND SHOULD REMAIN FULLY RETRACTED.
- VISIT OUR WEBSITE AT WWW.DRPOWER.COM, CALL 1-800-DR-OWNER (376-9637), OR CALL A
QUALIFIED HYDRAULIC MECHANIC FOR ASSISTANCE TO REPLACE WORN COMPONENTS.
• NEVER USE YOUR HAND OR ANY PART OF YOUR BODY TO CHECK FOR HYDRAULIC SYSTEM LEAKS
WHILE THE SYSTEM IS PRESSURIZED.
• NEVER REMOVE THE FILL/DIPSTICK CAP FROM THE HYDRAULIC FLUID PORT WHILE THE MOTOR IS
RUNNING OR WHILE THE TANK IS STILL WARM AFTER THE MOTOR IS OFF. HOT PRESSURIZED FLUID
CAN CAUSE SERIOUS INJURY, SO WAIT FOR THE HYDRAULIC TANK TO COOL BEFORE REMOVING CAP.
• THE WOOD SPLITTER MUST BE ON A LEVEL SURFACE.
• PERIODICALLY CHECK FOR HYDRAULIC FLUID LEAKS BY PLACING A SHEET OF CARDBOARD UNDER
THE WOOD SPLITTER WHILE THE SYSTEM IS RUNNING.
• GET PROFESSIONAL MEDICAL HELP AT ONCE IF HYDRAULIC OIL PENETRATES ANYONE'S SKIN.
• NEVER ADJUST THE HYDRAULIC SYSTEM.
