Protecting Yourself and Those Around You

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.

Safety for Children and Pets

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

THESE PRECAUTIONS:

• KEEP CHILDREN AND PETS AT LEAST 100 FEET FROM THE WORKING AREA AND ENSURE THEY

• BE ALERT AND TURN THE MACHINE OFF IF CHILDREN OR PETS ENTER THE WORK AREA.

ASSUME THAT CHILDREN WILL REMAIN WHERE YOU LAST SAW THEM. ALWAYS FOLLOW

ARE UNDER THE WATCHFUL CARE OF A RESPONSIBLE ADULT.

• NEVER ALLOW CHILDREN TO OPERATE THE BAC

HOE.

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

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.

Safety When Digging Near Utilities

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.

• SURVEY AND MARK THE AREA WHERE THERE ARE OVERHEAD POWER LINES AND DIG WITH

CAUTION UNDER POWER LINES TO ENSURE THAT YOU DO NOT TOUCH THEM WITH THE BACKHOE.

To w in g

• ALWAYS CHECK BEFORE TOWING TO MAKE CERTAIN YOUR BACKHOE 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 BACKHOE. BE SURE THE SAFETY CHAINS ARE PROPERLY HOOKED TO THE VEHICLE LEAVING ENOUGH SLACK FOR TURNING.

• ALWAYS INSTALL THE SWING AND BOOM TRANSPORT HITCH PINS AND LYNCH PINS BEFORE

TRANSPORTING THE BACKHOE.

• ALWAYS USE ACCESSORY LIGHTS AND DEVICES WHEN TRANSPORTING ON A ROAD OR

HIGHWAY TO WARN OPERATORS OF OTHER VEHICLES. CHECK YOUR LOCAL GOVERNMENT REGULATIONS.

• ALWAYS ALLOW FOR ADDED LENGTH OF THE BACKHOE WHEN TURNING, PARKING, CROSSING

INTERSECTIONS, AND IN ALL DRIVING SITUATIONS.

• ALWAYS BE CAREFUL WHEN BACKING UP. YOU COULD JACKKNIFE YOUR BACKHOE IF CARE IS

NOT TAKEN.

• NEVER EXCEED 45 M.P.H. WHEN TOWING YOUR BACKHOE. 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 BACKHOE.

• NEVER CARRY ANY CARGO ON YOUR BACKHOE.

• TRAVEL SLOWLY OVER ROUGH TERRAIN, ON HILLSIDES, AND AROUND CURVES TO PREVENT

TIPPING.

screw it in, to ensure an accurate reading and then remove it to check the oil level (clean the Dipstick with the rag after checking).

4. Continue adding a few ounces of oil at a time,

rechecking the Dipstick until the oil reaches the fill 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 3). Be careful not to overfill and reinstall 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.
