MISTS AND FUMES CONTAINING CHEMICALS KNOWN TO CAUSE SERIOUS FATAL INJURY OR ILLNESS, SUCH AS RESPIRATORY
DISEASE, CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM. IF YOU ARE UNFAMILIAR WITH THE RISKS ASSOCIATED
WITH THE PARTICULAR MATERIAL BEING CUT, REVIEW THE MATERIAL SAFETY DATA SHEET AND/OR CONSULT YOU EMPLOYER,
THE MATERIAL MANUFACTURER/SUPPLIER, GOVERNMENTAL AGENCIES SUCH AS OSHA AND NIOSH AND OTHER AUTHORI-
TIES ON HAZARDOUS MATERIALS. CALIFORNIA AND SOME OTHER AUTHORITIES, FOR INSTANCE, HAVE PUBLISHED LISTS OF
SUBSTANCES KNOWN TO CAUSE CANCER, REPRODUCTIVE TOXICITY, OR OTHER HARMFUL EFFECTS. CONTROL DUST, MIST
AND FUMES AT THE SOURCE WHERE POSSIBLE. IN THIS REGARD USE GOOD WORK PRACTICES AND FOLLOW THE RECOM-
MENDATIONS OF THE MANUFACTURER/SUPPLIER, OSHA/NIOSH, AND OCCUPATIONAL AND TRADE ASSOCIATIONS. WHEN THE
HAZARDS FROM INHALATION OF DUST, MISTS AND FUMES CANNOT BE ELIMINATED, THE OPERATOR AND ANY BYSTANDERS
SHOULD ALWAYS WEAR A RESPIRATOR APPROVED BY OSHA/MSHA FOR THE MATERIAL BEING CUT.
Charger Operation
Ensure proper use of charger.
• Once connected and plugged into AC power, the LED will in-
dicate whether or not it is charging. Refer to manufacturer’s
charger manual.
• Only use charger on branch circuits protected by a circuit
breaker or fuse that can carry the power of the charger.
• Do not use charger if it shows signs of physical stress, or if
DC output leads or connector feel hot when used.
• Do not disconnect DC output clamps or connector from bat-
teries while charger is on. This could cause an explosion.
• Failure to unplug AC power before moving equipment will
damage cords, plugs, and receptacles.
• Do not over-discharge batteries, this could cause batteries
to fail. Re-charge as soon as possible after discharge; if they
are warm, rst allow them to cool.
• Charger is not water proof, only resistant, and cannot with-
stand immersion, continuous exposure, or heavy rain.
• A drive lockout option will disable the drive mechanism of
the machine while the charger is plugged in.
• There is a built-in Low Voltage Interrupter that continuously
monitors for low voltage and will sound when voltage falls. At
44V the alarm will sound; stop immediately and recharge. At
43.5V the machine will auto-disconnect and shut down; let
machine sit until batteries recover enough to drive to outlet.
• Chargers are equipped with a grounding plug.
Note: Leaving the charger plugged in does not harm the battery
and is preferred to leaving the battery in a state of discharge.
Scraping
Do not drive machine along hills or uneven surfaces.
The weight of the machine may become distributed differently if on
an uneven surface. Too much of an angle could make the machine
unsafe or cause it to tip over. Always keep the front of the machine
facing downward while traveling up or down ramps or inclines. Do
not run the machine in unsafe environments.
Inspect work area for potential hazards prior to operation.
Observe location of electrical supplies and extension cords.
Do not allow cutting heads to come into contact with any electrical
supply or extension cord.
Operator must be seated before starting machine and should
stay seated until motor has stopped running.
This machine is equipped with a safety switch under the seat,
which requires the operator to be seated before the machine can
be operated. Do not attempt the start-up procedure without rst
being seated on the machine.
Batteries and Chargers
Use caution; risk of explosive gases.
Batteries generate explosive gases during normal operation. Do
not use near fuels, grain, dust, solvents, or other ammables;
never smoke near the machine, battery, or charger.
Inspect battery and charger regularly.
Disconnect charger from wall outlet before operating. Machine
should be off before connecting to a power source. Periodically
inspect batteries, cables, charger, and all plug connections. Be
extremely cautious when working with batteries. Do not open or
tamper with batteries; doing so could cause electrical shock.

HYDRAULIC SAFETY
Maintaining a Safe Work Environment
Establishing a safe work environment in and around your hydraulic equipment is extremely important. The easiest and most effective way to
avoid problems is to make sure associates understand their equipment, know how to operate the machines safely, and recognize the dangers if
handled carelessly. A few things to be aware of are:
• Pressure: Hydraulic uid under pressure is dangerous and can cause serious injury. Never look for a leak when unit is under pressure.
Using your hand could cause serious injury. A few common ways to encounter hydraulic uid under pressure include:
▪ Pinhole: Fluid under pressure can cause serious injury. It can be almost invisible escaping from a pinhole, and it can pierce the skin
into the body.
▪ Leak: Keep ttings and hoses tight. Only check and service when not under pressure. Leaking hydraulic uid is hazardous; in addition
to making workplace oors slippery and dangerous, it also contaminates the environment. Before cleaning an oil spill, always check
EPA, state, and local regulations.
▪ Burst: Whether due to improper selection or damage, a ruptured hose can cause injury. If it bursts, a worker can be burned, cut,
injected, or may slip and fall.
▪ Coupling Blow-Off: If the assembly is not properly made or installed, the coupling could come off and hit or spray a worker, possibly
resulting in serious injury. Never operate machine without guards.
• Flammability: When ignited, some hydraulic uids can cause res and/or explode.With the exception of those comprised primarily of
water, all hydraulic uid is ammable (including many “re-resistant” hydraulic uids) when exposed to the proper conditions. Leaking pres-
surized hydraulic uids may develop a mist or ne spray that can ash or explode upon contact with a source of ignition. These explosions
can be very severe and could result in serious injury or death. Precautions should be taken to eliminate all ignition sources from contact
with escaping uids, sprays or mists resulting from hydraulic failures. Sources of ignition could be electrical discharges (sparks), open
ames, extremely high temperatures, sparks caused by metal -to -metal contact, etc.
• Mechanical: Hydraulic uid creates movement, which means some equipment may move. Observe surroundings and equipment at all
times.
• Moisture: Do not use in wet or high moisture conditions.
• Electrical: Faulty wiring can be an electrical hazard. A regular preventive maintenance program should always include a wiring check. If
applicable, disconnect battery before serving.
• Temperature: Because this machine operates at a relatively low pressure, overheating is not common. If surface of tank becomes too hot
to touch by hand (above 130ºF or 55°C), shut off machine and allow it to cool.
Hydraulic Fluid
Only use Texaco Rando 46 Hydraulic Oil or compatible uid like ISO or AW #46 from a brand name manufacturer. Non-compatible uids could
cause damage to unit or serious injury.
CAUTION: NEVER USE YOUR HANDS TO CHECK FOR LEAKS OVER HOSE OR HYDRAULIC CONNECTIONS. USE A PIECE OF CARD-
BOARD TO LOCATE A PRESSURIZED LEAK. FOR LOW PRESSURE LEAKS (DRIPS), USE A RAG TO CLEAN THE AREA AND DETERMINE
WHERE THE LEAK ORIGINATES.
DANGER: DO NOT TOUCH A PRESSURIZED HYDRAULIC HOSE ASSEMBLY WITH ANY PART OF THE BODY. IF FLUID PUNCTURES
THE SKIN, EVEN IF NO PAIN IS FELT, A SERIOUS EMERGENCY EXISTS. OBTAIN MEDICAL ASSISTANCE IMMEDIATELY. FAILURE TO DO
SO COULD RESULT IN LOSS OF THE INJURED BODY PART OR DEATH.

WARNING: THE BACK-UP BEEPER IS ON THE MACHINE FOR SAFETY. IT IS IMPORTANT TO KEEP IT IN GOOD WORKING CONDI-
TION. FAILURE TO DO SO COULD CAUSE BODILY INJURY.
