38.

Do not attempt to install or adjust control cables with the engine running.

39.

Always replace a control cable which exhibits any gradual or sudden increase in no-load

friction or resistance or decrease in usable stroke, or which have moisture inside or have
been frozen.

40.

Do not use heat to attempt to dry or thaw a control cable.

41.

Do not remove the seats from a control cable or attempt to lubricate it.  Any control cable

which exhibits possible lubrication problems should be replaced.

42.

Do not attempt to repair or modify a control cable. Any damaged control cable should be

replaced immediately.

43.

Always avoid exposing control cables to fuels, oils, chemicals, paint, water or dirt as

damage may result.

44.

Always adjust each control cable so that the utilized stroke of the cable is centered within

the cable’s available stroke.

45.

Always deflate a tire and wheel assembly prior to removing it for servicing or dismounting.

46.

Do not use wheels or wheel components that are cracked, bent, pitted or corroded. Insure

all wheel components are of the same type and size and that wheel size and tire size
match. Inspect all components carefully prior to use.

47.

Do not attempt to seat a tire bead or side or lock ring by using inflation pressure or any

flammable or explosive substance such as starting fluid or ether. Never inflate a tire
beyond 40 psi to seat tire beads.

48.

Do not hammer, pry or weld on or near an inflated or partially inflated wheel and tire

assembly.

49.

Do not rework, weld, heat or braze any wheel parts for any reason.

50.

Always use a safety cage or other restraining device and a clip-on air chuck with a remote

valve and pressure gauge when inflating a tire.  Insure the tire and wheel assembly is
properly assembled prior to inflating it. Visually inspect it for proper seating of beads and
side or lock rings prior to removing it from the cage.

51.

Do not add air to a tire that has been in service with less than 80% recommended pressure

without first fully deflating, removing, disassembling and inspecting the tire assembly for
damage.

MECHANIC RESPONSIBILITIES (CONT)

52.

Immediately replace any parts that show wear or deterioration.

53.

Check the condition and tightness of all fasteners.  Always use Grade 8 heat treated bolts

throughout the unit. Grade 8 heat treated bolts can be identified by six lines on the bolt
head.

54.

Always keep good maintenance records.

55.

Never engage in “horseplay” with the tractor.

56.

Always exercise good common sense, stay alert and be aware of what is happening

around the tractor at all times.  Take nothing for granted when the safety of the tractor or
the operator is at stake. Remember, the operator is depending on you to provide him with a
safe tractor.

WARNING: MODIFICATIONS TO THIS UNIT ARE TO BE MADE ONLY BY THE

ORIGINAL MANUFACTURER OR A CERTIFIED TESTING LABORATORY.

DRY CHEMICAL (PURPLE K) FIRE EXTINGUISHER USE AND MAINTENANCE

Dry chemical fire extinguishers are provided as optional safety equipment on some MA taw
tractors. To be effective in combatting small fires, these devices must be properly maintained
and the operator must have a thorough knowledge of their operation.

WARNING: THESE FIRE EXTINGUISHERS SHOULD NEVER BE USED TO FIGHT LARGE

FIRES. FIRE SPREADS RAPIDLY AND A FIRE WHICH EXCEEDS THE CAPACITY OF A
PORTABLE FIRE EXTINGUISHER IS LIKELY TO QUICKLY OVERCOME THE FIRE
FIGHTER, RESULTING IN SERIOUS INJURY OR DEATH. AS SOON AS ANY FIRE STARTS,
THE LOCAL FIRE DEPARTMENT SHOULD BE NOTIFIED IMMEDIATELY AS ANY FIRE CAN
QUICKLY GROW TO A POINT AT WHICH IT CAN ONLY BE EFFECTIVELY COMBATTED
USING LARGE QUANTITIES OF WATER OR OTHER MEDIUM.

Three things are required to sustain a fire. These are fuel (any combustible material such as
paper, petroleum based fluids, etc.), heat and oxygen (in the air). Removing any one of these
elements is sufficient and necessary to put out a fire. Dry chemical fire extinguishing agents put
out fire by removing the oxygen from (smothering) the fire.

To use the dry chemical fire extinguisher to combat a fire:

1.

Remove the fuel and/or heat source of the fire if at all possible. If the fire is in an engine,

turn off the engine. If the fire is in electrical equipment, turn off the electrical power to the
burning equipment. If the fire is a combustible liquid fire, attempt, if possible, to shut off
the flow of the combustible liquid to the fire.

2.

Hold the extinguisher upright and remove the ring pin

from the handle by breaking the plastic seal and pulling
the pin out.

3.

Stand approximately 8 feet from

the base of the fire.

4.

Aim the nozzle at the base of the

fire

and squeeze the lever. Apply the
extinguishing agent to the base of

the

fire using a side-to-side sweeping
motion.

E.

DRY CHEMICAL FIRE EXTINGUISHER USE AND MAINTENANCE (CONT)

WARNING: DO NOT DISTURB THE DRY CHEMICAL EXTINGUISHING AGENT ONCE IT
HAS BEEN APPLIED UNTIL THE FUEL HAS COMPLETELY COOLED. THE DRY CHEMICAL
EXTINGUISHING AGENT PUTS OUT FIRE BY SMOTHERING IT. IF IT IS REMOVED FROM
THE MATERIAL WHICH WAS BURNING WHILE THE MATERIAL IS STILL HOT, EXPOSURE
TO THE OXYGEN IN THE AIR CAN RESULT IN REFLASH OF THE FIRE.

MAINTAINING THE DRY CHEMICAL FIRE EXTINGUISHER:

EVERY 30 DAYS: Fire extinguishers must be visually inspected upon initial placement into
service and every 30 days thereafter.

Inspect for:

1.

Proper pressure as indicated by the pressure gauge near the top of the extinguisher. The

needle should be in the green region.

2.

Cleanliness. Remove any dirt, oil, grease, etc. Check for chemical build Up.

3.

Damage. Ensure that the ring pin and plastic seal are intact and properly installed and that

the extinguisher shows no sign of damage.

4.

Proper installation. Be sure that the extinguisher is properly installed and that installation

devices are not loose or damaged.

5.

Interference. Ensure that the extinguisher is easily accessible and can be quickly removed

from its installation device in case of emergency.

ANNUALLY: Fire extinguishers must be serviced by a licensed company at least annually or
when indicated by an inspection.

EVERY 6 YEARS: Dry chemical fire extinguishers must be emptied, inspected and overhauled
by a licensed company at least every six years.

EVERY 12 YEARS: Dry chemical fire extinguishers must be hydrostatically pressure tested by a
licensed company at least every twelve years.
