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.

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.
Figure 17

TO AVOID DAMAGE TO THE BACKHOE, DO NOT SLAM THE
SWING UNIT INTO THE END OF THE SWING CYLINDER
STROKE.
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.
