SAFETY INSTRUCTION
ALWAYS PRACTICE SAFETY BY THINKING BEFORE ACTION
AVOID FIRE HAZARDS.
-Keep fire extinguishers easily available and in good operating condition.
All relevant personnel should know how to operate fire fighting equipment.
-Keep a first aid kit in an easily accessible location.
-Do not smoke while handling fuel,or other highly flammable material.
-Do not use an open pail for transporting fuel.
-Use of an approved fuel container.
-Dispose of all fuel-soaked rags in covered containers where cigarettes cannot be dropped
carelessly.
-Do not smoke and avoid open flame when charging,jumping,or boosting batteries.
-Batteries give off gas which is flammable and explosive.
-Do not charge batteries in a closed area. Provide proper ventilation to avoid explosion of
accumulated gases.
Avoid acid burns.
-Wear safety goggles when handling battery electrolyte.It contains sulfuric acid which is a poison
and can cause blindness.Avoid it contacting eyes,skin,or clothing. sulfuric acid will eat through
clothing and can cause severe burns to skin.
AVOID HIGH-PRESSURE FLUIDS
1) Before beginning work on hydraulic system components,turn off engine and operate hydraulic
control levers to relieve internal hydraulic pressure.
2) Oil under pressure can penetrate skin and lead to personal injury.Treat sources of oil pressure
with extreme care,wearing safety goggles.
3) If hydraulic leak develops,correct immediately.Escaping hydraulic oil can have extremely high
pressure. A stream of high pressure oil may easily penetrate skin just like modern needless
vaccination equipment,but with the exception that hydraulic fluid may cause blood poisoning.
It is imperative that connections are tight and that all lines and pipes should be in good condition.
If injured by escaping hydraulic fluid,see a doctor at once.

STAY CLEAR OF PTO
1) Entanglement in rotating drive line can cause serious injury or death.
2) Keep tractor master shield and drive line shield in place at all times except for special applications
as directed in the implement operator's manual.
3) Wear fairly tight tight fitting clothing.Stop the engine and be sure PTO driveline is stopped before
making adjustment,connections,or cleaning out PTO drive equipment.
SERVICE TIRES SAFELY
Tire changing can be dangerous and should be done by trained personnel using proper tools and
equipment.
Do not re-inflate a tire that has been run flat or seriously under-inflated.Have it checked by qualified
personnel.
Use wheel handling equipment adequate for weight involved when removing and installing wheels.

USE OF ROPS AND SEAT BELT
The Roll Over Protective Structure(ROPS) has been certified to industry
and/or government standards. Any damage or alternation to the ROPS,
mounting hard-ware, or seat belt voids the certification and will reduce or
eliminate protection for the operator in the event of a roll-over. The ROPS,
mounting hardware, and seat belt should be checked after the first 100
hours of Tractor and every 500 hours thereafter for any evidence of
damage, wear or cracks. In the event of damage or alteration, the ROPS
must be replaced prior to further operation of the Tractor.
The seat belt must be worn during machine operation when the machine is
equipped with a certified ROPS.
Failure to do so will reduce or eliminate protection for the operator in the
event of a roll over.
PRECAUTION TO AVOID TIPPING
Do not drive where the Tractor could slip or tip.
Stay alert for holes and rocks in the terrain, and other hidden hazards.
Slow down before you make a sharp turn.
Driving forward out of a ditch or mired condition could cause Tractor to
tip over backward. Back out of these situations if possible
PARK TRACTOR SAFELY
Before working on the Tractor ;
Lower all equipment to the ground.
Stop the engine and remove the key
KEEP RIDERS OFF TRACTOR
Do not allow riders on the Tractor.
