If engine does not start

Return the key to position '0', wait 30 seconds and repeat

A maximum of 6 starting cycles is allowed (15 seconds
start and 30 seconds interruption is one cycle). Another
engine start is allowed after the starter cools off to

Never help a stopping tractor with a starter.
There is a danger of starter damage.

Manipulation with starter

It is forbidden to start by short circuiting starter
clamps! Tractor is started only from driver's seat!
With any manipulation or starter repair it is necessary
to disconnect minus battery pole and all shifting
levers including PTO shaft shifting lever must be in
neutral position!
Starter contacts are covered with a cap.

Immediately after start

After starting, set revolutions to 800 - 1,000 rpm
and let engine run without load for a period of app.
2 minutes.
Check greasing, charging and other functions ensuring
proper engine operation (controls must go out) in this time.
The time of engine operation without load must be
observed, in particular in winter period.

Engine heating

Do further heating of the engine when driving. Heating engine by lengthy idle run or abrupt
