Protecting Yourself and Those Around You
Safety for Children and Pets
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 BACKHOE 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 BACKHOE. BE SURE YOUR GLOVES FIT
PROPERLY AND DO NOT HAVE LOOSE CUFFS OR DRAWSTRINGS.
• WEAR SHOES WITH NON-SLIP TREADS WHEN USING YOUR BACKHOE. IF YOU HAVE SAFETY
SHOES, WE RECOMMEND WEARING THEM. DO NOT USE THE MACHINE WHILE BAREFOOT OR
WEARING OPEN SANDALS.
• WEAR LONG PANTS WHILE OPERATING THE BACKHOE.
• USE EAR PROTECTORS OR EAR PLUGS RATED FOR AT LEAST 20 DBA TO PROTECT YOUR HEARING.
• KEEP BYSTANDERS AT LEAST 100 FEET AWAY FROM YOUR WORK AREA AT ALL TIMES. LOWER THE
BUCKET AND STOP THE ENGINE WHEN ANOTHER PERSON OR PET APPROACHES.
• POSITION A BARRICADE AROUND THE WORK AREA.
• NEVER ALLOW A PERSON TO WORK UNDER A RAISED BUCKET.
• NEVER LIFT A PERSON WITH THE BACKHOE.
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 DIGGING ACTIVITY.
NEVER ASSUME THAT CHILDREN WILL REMAIN WHERE YOU LAST SAW THEM. ALWAYS FOLLOW
THESE PRECAUTIONS:
• KEEP CHILDREN AND PETS AT LEAST 100 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 BACKHOE.
8 DR® DIRT BOSS™ TOWABLE BACKHOE
Safety with Gasoline - Powered Machines
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 AND FUEL CONTAINER CAPS 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.

Hydraulic Safety
Safety When Digging Near Utilities
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
BEFORE CHANGING OR ADJUSTING FITTINGS, HOSES, TUBING, OR OTHER SYSTEM
COMPONENTS.
• DO NOT CHANGE ANY BACKHOE NEEDLE VALVE SETTINGS. THEY ARE SET AT THE FACTORY
FOR BEST BACKHOE 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.
CALL 811 BEFORE YOU BEGIN ANY DIGGING PROJECT. A NEW, FEDERALLY-MANDATED NATIONAL
"CALL BEFORE YOU DIG" NUMBER, 811 WAS CREATED TO HELP PROTECT YOU FROM
UNINTENTIONALLY HITTING UNDERGROUND UTILITIES WHILE WORKING ON DIGGING PROJECTS.
EVERY DIGGING JOB REQUIRES A CALL. IF YOU HIT AN UNDERGROUND UTILITY LINE WHILE
DIGGING, YOU CAN HARM YOURSELF OR THOSE AROUND YOU, DISRUPT SERVICE AND
POTENTIALLY BE RESPONSIBLE FOR FINES AND REPAIR COSTS.
• THERE MAY BE BURIED POWER, GAS, AND/OR TELEPHONE LINES IN THE WORK AREA. ELECTRIC
SHOCK, DEATH, OR EXPLOSION MAY OCCUR.
• HAVE THE PROPERTY OR WORK AREA MARKED FOR BURIED LINES AND DO NOT DIG IN
MARKED AREAS.
• THERE MAY ALSO BE OVERHEAD POWER LINES IN THE WORK AREA. ELECTRIC SHOCK OR
DEATH MAY OCCUR IF A POWER LINE IS TOUCHED BY THE BACKHOE.

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 BACKHOE.
• NEVER CARRY ANY CARGO ON YOUR BACKHOE.
• TRAVEL SLOWLY OVER ROUGH TERRAIN, ON HILLSIDES, AND AROUND CURVES TO PREVENT

16. Start the Backhoe engine and get into the Operator
seat to raise the Boom to lower the Backhoe onto the
Front Stabilizers (Figure 17).
Digging with the Backhoe
It is not difficult (but it does take practice) to become an
efficient operator. A control lever operating decal is located
just forward of the control levers. Study this decal; it will
help you become familiar with the controls. See Figures 6
and 7 for control locations and functions.
Smooth, light handling of the controls will result in the
most efficient machine operation. Operate the backhoe
control levers to become familiar with their speed and
movements. The engine speed will determine the speed of
the cylinder operation.
Swing the boom several times to practice controlling the
speed of the swing. Do not operate the swing more than
45 degrees each way for the first few times. Gradually
increase the arc.
Best results are obtained by digging near the center of the
swing arc so material can be dumped to either side.
Bucket Digging
1. Lower the Bucket to the digging area with the Bucket
pivot 18" to 24" forward of the Boom/Crowd Arm pivot
(Figure 18).
NOTE: It is important for the Bucket to be in the proper
position for digging efficiency. The Bucket will not dig
as well if you attempt to dig with the Bucket in the
wrong position, tilted too far forward or too far back
(Figure 19).
2. Using down pressure on the Bucket bottom, force the
Bucket into the ground.
Figure 18
18" to 24"
TO AVOID DAMAGE TO THE BACKHOE, DO NOT SLAM THE
SWING UNIT INTO THE END OF THE SWING CYLINDER
STROKE.

24 DR® DIRT BOSS™ TOWABLE BACKHOE
3. With the Bucket in the ground, simultaneously retract the Crowd Arm and load the Bucket until it is
full (Figure 18).
4. If the Bucket stalls, raise the Boom slightly and continue to dig until the Bucket is full.
5. Raise the Bucket to the top of the trench and dump it on the spoil pile.
6. When lifting the loaded Bucket high, continue rolling the Bucket in as it is being raised to prevent
spilling the contents.
NOTE: With a little practice, raising, swinging, and dumping can be accomplished in one smooth operation.
Crowd Arm Digging
1. Lower the Bucket to the digging area with the Bucket
pivot 18" to 24" forward of the Boom/Crowd Arm
pivot.
2. Rotate the Bucket until the cutting edge teeth are flat
on the ground.
3. Using only the Crowd Arm Control Lever, retract the
Crowd Arm, dragging the Bucket through the trench
until it is about half full. Roll the Bucket as you
continue to retract the Crowd Arm.
4. Raise the Bucket and swing the Boom until the Bucket
can be dumped in the spoil area.
Preparing the Backhoe for Moving/Towing
1. Lift the front of the Backhoe by lowering the Boom
until the Front Stabilizers lift slightly off the ground
(Figure 20).
2. Move the Throttle Lever to the idle position (Figure 9)
and turn the Ignition Switch of the Engine to the
“OFF” position (Figure 8).
3. Pull the Front Stabilizer Lynch-Pins from the Hitch
pins and remove the Hitch Pins (Figure 21).
