Return to Index
Safety
Emergency Preparedness
Keep a serviceable re extinguisher on the tractor at the
designated place shown in Section 2.5, Fig. 13, page 39,
for use in the event of a re. Avoid res by removing and
keeping ammable materials from accumulating on the
tractor. Repair oil and fuel leaks before using the tractor.
Keep a complete rst aid kit in the Cab for emergency
use. Inspect frequently to ensure the kit is complete and
materials are within effective date codes. Keep a list of
doctor, EMS, Fire Department and hospital in a visible
place in the tractor. Keep a duplicate list on your mobile
phone.
Clothing
Wear close tting comfortable close and shoes during tractor
operation. Additional protective clothing may be required based on
the task the operator is performing. The operator needs to devote
complete attention to tractor operation and avoid distractions such as
music earphones, mobile phone use and unnecessary passengers in
the tractor Cab.
Fuel handling and Tractor Fueling
Fuel is highly ammable. Do not smoke around fuel, containers
of fuel and during tractor refueling. Avoid exposing fuel and
fueling operations to open ames and sparks. Always stop
the tractor engine before refueling. Store bulk fuel outside in
approved storage tanks. Transport fuel in approved containers.
Do not transport fuel in unapproved containers made from
glass, waxed cardboard, plastic household bottles. Old oil
containers or any other unapproved container. Do not store
fuel containers near open ames, sparks from any source
and pilot lights. Always place transportable fuel containers on
the ground before attempting to ll with fuel. Before removing
the cap touch the nozzle to the container to discharge any potential static electricity. While lling the
container keep the nozzle in contact with the container to avoid a static electricity discharge. This is
particularly important when transferring ULTRA LOW SULPHUR FUEL.
Hearing Protection
The tractor Cab environment provides a low noise level during operation with the
door and window closed and does not require ear protection. Repair or replace any
damaged door and window components to ensure the integrity of the Cab when
new. Consult your MTZ for repair and replacement. Operating machinery in excess
of 90dBA noise levels for extended periods of time will cause hearing loss and
requires hearing protection. Ear protection requires heightened awareness on the
part of the user to offset the loss of auditory input. Remove the ear protection when
no longer in the noisy area.

MTZ-KIROVETS K744 OPERATOR MANUAL
18 Return to Index
Starting Fluid Safety
Starting uid is highly ammable. Do not smoke while using starting uid.
Remove all ame sources and potential spark generating devices from
the area where the starting uid will be used. It is particularly important
to ensure jumper Cable connections are secure and will not spark if the
tractor battery is being boosted during starting. When not in use replace
the cap rmly and store the container in a cool dry place. Do not leave
exposed to sunlight. Do not store in the tractor Cab. Starting uid must
not be used on diesel engines equipped with glow plugs or electric inlet
heaters to avoid an explosion. Do not incinerate or puncture the container
to avoid possible explosion and injury. Dispose of the container according
to the manufacturer instructions on the container.
Fire Prevention
Inspect the tractor prior to use each day and remove ammable materials
such as crop debris, bird nest, mice nests, oil, grease, fuel and any other
types of ammable materials touching or near components that become hot
during operation. In some agricultural tractor usage ammable material can
be a constant hazard. Under these circumstances be vigilant and clear the
material as frequently as necessary to avoid a re hazard, Clean the tractor
regularly to avoid the risk of re. Before each use inspect the tractor and
equipment used with the tractor for hydraulic and fuel leaks. If leaks are
present repair the leak and clean the area of leaked oil from the tractor and equipment before operating
the tractor. Inspect electrical components, batteries and Cables. Repair or replace any frayed Cables,
damaged batteries or malfunctioning electrical components before using the tractor. Be particularly vigilant
of leakage around hose connections and lters. Before cleaning the tractor refer to Section 2.5, Page
36 in this manual for the recommended equipment and method of cleaning the tractor. In general, stop
the engine, place the transmission in neutral, engage the park brake, lower implements if applicable and
close the Cab doors and windows. Wait until the hot components have cooled to a touchable temperature
before proceeding with the inspection and cleaning.
If a re occurs;
• At the rst sign of smoke or ames stop the tractor and the engine and leave the tractor,
• Call the re department,
• Assess whether or not the re is manageable with the re extinguisher,
• When using the extinguisher keep your back to the wind to avoid smoke and ames,
• Before using the extinguisher ensure it is correct for the type of re in progress,
• Local re departments can assist with proper classication of the extinguisher and its use,
• Follow the extinguisher instructions,
• Pull the retainer pin holding the nozzle away from you and release the lever,
• Aim the nozzle low toward the base of the re,
• Squeeze the extinguisher lever slowly and evenly,
• Sweep the nozzle from side to side
•

Safety
Ultra Low Sulphur Fuel Hazard
Ultra low Sulphur fuel is a poor conductor of electricity. Static electricity can
build up as the fuel is transferred from storage to a fuel tank building an electro
static charge. Reneries incorporate an additive at the renery to reduce the
characteristic. The additive can degrade over a few months reducing the fuels
ability to resist static charge build up when transferred. Ultra low Sulphur fuel
storage requires a compliant grounded and bonded system to avoid the danger
from a static charge igniting the fuel. A compliant system insures that every
component of the fuel system from the storage tank to the discharge nozzle is
grounded.
Roll Over Protective Structure
This tractor has a Roll Over Protective Structure (ROPS) incorporated
in the Cab enclosure. If your Cab is damaged ask your MTZ dealer
to inspect the damage before using the tractor. Any permanent
deection of the Cab components or deformation of corner areas
indicates that the ROPS is no longer capable of protecting the
operator space in the event of a roll over incident. The Cab must
be replaced before the tractor is used. Any permanent deection of
the frame mounting structure for the Cab must also be examined
and repairs made before using the tractor. Do not drill holes in the
Cab ROPS structure. Do not weld on the ROPS structure. Contact
your MTZ dealer to determine where attachments can be made to
the Cab without causing damage to the ROPS. Any modication to
the Cab ROPS will invalidate the performance certication. A Cab that has been involved in a re is no
longer a certied ROPS and must not be used on the tractor. The seat belt is an integral part of the safety
system in a roll over incident for the operator and trainer.
Seat Belts
Aseat belt is provided for the operator and trainer seat. During operation the operator and trainer if
present must wear the seat belts provided. In the event of a roll over incident the seat belt will keep
occupants within the protected zone of the ROPS reducing the potential injury severity. Proper seat belt
use is explained in detail in below. The general procedure for seat belt use is;
1. Sit in the seat and adjust it to the comfortable operating position,
2. Hold the latch and bull the seat belt across the lower torso area of the body ,
3. Firmly insert the latch into buckle until a distinct click is heard,
4. Tug on the seat belt latch to ensure the belt is securely fastened,
5. Adjust the seat belt until it is snug across the torso.
Inspect the seat belt each time it is used. If the latch malfunctions or webbing
damage is visible repair the malfunction and frayed webbing before using the
tractor. Use the MTZ specied hardware to fasten the seat belt components to
the seat structure to ensure correct performance to the certied standard. Seat
belt webbing exposure to sunlight will cause the webbing material color to fade.
Faded material is an indication that exposure has weakened the material strength. Replace faded seat

Avoid rotating Drivelines
Entanglement in rotating shafts and drivelines can cause
serious injury or death.
Wear close tting close and avoid the rotating shaft. Before
approaching the shaft stop the driveline, engine and
wait until the drive shaft has stopped before connecting/
disconnecting, adjusting or cleaning PTO driven equipment.
Ensure that the undamaged tractor master shield is in place
at all times with the proper safety message. If the master
shield is damaged or the safety decal illegible replace to
ensure original equipment performance before using the
tractor. A rotating shield must turn freely. If not repair the
malfunction before using the PTO driven equipment. Ensure
that all guards and shields are in place on the PTO driven
equipment before use. Do not install an adapter shaft that
will permit connection of a 540 RPM
PTO machine to a 1000 PTO tractor output shaft. Do not install an adapter shaft that extends the end
of the tractor driven shaft beyond the master shield. See accompanying shield illustration for the proper
shield extension dimension by PTO type.
PTO Type Diameter Splines n ± 0.20 in. - 5 mm
1 1.378 in. - 35 mm 6 3.35 in - 85 mm
2 1.378 in - 35 mm 21 3.35 in. - 85 mm
3 1.772 in - 45 mm 20 4.00 in - 100 mm
4 2.264 in - 57.5 mm 22 4.00 in. 100 mm
Make a trial connection for 3-point hitch implements driven by the tractor PTO. Slowly raise the implement
to determine if the master shield will clear the PTO shaft in the fully raised position. If necessary restrict
lift height to prevent damage to the master shield and other PTO shaft guarding components.
Steps and Handhold Use
Always face the tractor when using the steps and handholds for access to the
tractor Cab maintaining three-point contact with steps, handholds and handrails.
Keep the steps clear of debris, mud and other slippery materials. Keep handhold
sand handrails clean and free of slippery material such as grease, oil, ice and
snow to prevent loss of grip during use. Do not attempt to use the access system if
the tractor is moving. Do not jump from the tractor Cab when exiting the machine.
