INTRODUCTION:

• This manual contains procedure of disassembly-assembly of units and assemblies, data on
  their design and operation, adjustment and technical characteristics of units of tractors
  BELARUS 1221.2/1221В.2/1221.3/1221.4 with engines MMZ and Deutz. It is an indispensible
  guide for maintenance personnel engaged in repair or maintenance.
• To obtain exhaustive information about tractors use this manual, as well as “Operating
  manual for tractor BELARUS 1221” and its modifications, enclosed with each tractor.
  Data contained in this manual is accurate at the time of this manual compilation.
• As tractors BELARUS are continually updated, Minsk Tractor Works PA reserves the right to introduce
  design amendments without notifying the customers. All data given in this manual can be
  amended, and illustrative materials can differ from those describing tractors currently
  manufactured.

1 SAFETY REQUIREMENTS:
For your safety purpose carefully study this manual before starting maintenance and repair
works. Pay particular attention to all warnings and recommendations given in this manual.
Always consult operating and maintenance manual issued by the manufacturer.
1. Any equipment can present danger for personnel. Remember that careless steering or
wrong maintenance can be the source of danger both for an operator and his associates.
2. Strictly follow safety regulations in handling lifting and transport mechanisms. Tractor lifted
above the ground by means of lifting mechanisms and poorly fastened by ropes can fall down on
you. Before jacking one of the axles, put the tractor on hard even surface. Another axle must be
securely blocked with wedges (pads) put under wheels. Do not loll tractor against slag bricks,
hollow tiles or other supports that can collapse by tractor weight. Do not work under tractor lifted
only by jack, and observe all recommendations given in this manual.
3. Before starting to disassembly tractor into components, carefully clean adjacent assembly
units from dust, mud, oil and grease.
4. When disengaging power transmission constituents, use disengagement tool. Securely put
transmission constituents on supports and jacks. Do not rely solely on jacks to support tractor
when working under it: tractor can move from jacks and injure or maim you, unless wheels are
blocked with wedges on both sides. Always block front and rear wheels of tractor which must
always be jacked. Always place raised section of tractor on supports before starting any work.
5. Make sure tractor will remain immobile: shift gear in the gear box, engage parking brake,
shut down the engine and pull out key from starter switch and instruments. Disconnect storage
battery to rule out possibility of starting engine by someone else, while you are working under
tractor.
6. Wear suitable protective cloths (gloves, footwear, working cloths) and goggles.
7. Use serviceable and suitable tools. Self-made (provisional) tools and wrong work techniques
can result in dangerous situation. Use mechanical tools only for loosening fasteners. Use proper
size tools for tightening and loosening fittings. Do not use “inch system” tools for metric fasteners.
Avoid possibility of injuring caused by wrench slippage.
8. To avoid burns take care when draining hot oil from filling tanks of hydraulic system, power
transmission and FDA. Leaks of oil, lubricants, solvents and other liquids that can pollute
environment and be harmful for your health must be properly disposed in accordance with local
legislation and regulations.
9. Refill filling tanks and use only fuel, oils, lubricants and special liquids recommended by the
manufacturer according to annexes “Recommended oils, fuels, lubricants and special liquids” listed
in operating manuals for tractor and engine installed on it.
DO NOT USE OTHER LUBRICANTS!
