7. Maintenance schedule
a. Service
Correct maintenance at the right time is a basic
condition for reliable operation of the tractor.
Maintenance costs are small compared with any
repair costs resulting from lack of maintenance. The
most important measures are those which you carry
out yourself and which include lubrication and
various checks and adjustments.
The service intervals shown apply for normal
operating conditions but in more severe conditions
servicing should be carried out more frequently.
7.1.1. General instructions concerning
oil checks and oil filling
− Always stop the engine before doing any servicing
work.
− Apply the parking brake to ensure the tractor
cannot move. If the ground is uneven the wheels
should be blocked.
− Always observe the utmost cleanliness in all
maintenance work.
IMPORTANT: Do not let the water get to the
electrical equipment when washing the machine.
− Thoroughly wipe off filler caps and plugs as well
as surrounding parts of the tractor before filling up
with fuel or oil.
− Inspect the oil and filters when changing. Large
amounts of dirt (e.g. heavily clogged filters) can
point to a fault which could cause extensive and
costly repairs if not corrected in time.
− When carrying out checks the tractor should stand
on level ground.
− Levels should be checked before driving when the
oil is cold and has had time to run down to the
bottom of the unit concerned.
− When changing the oil, bear in mind that the oil
can be very hot when it drains from the tractor.
− Avoid touching the exhaust manifold, turbocharger
and other hot parts of the engine.
− Keep the engine surfaces clean in order to avoid
the risk of fire.
− The fuel, lubricating oil and coolant cause irritation
to skin if in contact for long periods.
− After completion of any service work replace all
safety covers etc.
− Waste oil, liquid waste, oil filters and batteries
should be handled carefully and disposed of
properly.
7.1.2. Lubrication of points provided
with grease nipples
− Always clean the grease nipples before applying
the grease gun.
− Pump in grease to the nipples until clean grease
is squeezed out (unless otherwise instructed).
− Wipe off all surplus grease which has been
squeezed out at the lubricating points.
− Preferably carry out lubrication with bearing points
and joints unloaded and with the bearings in
different positions ( e.g. lubricate the steering
knuckle bearing on the steering axle with the wheels
at both full left and right lock and with the front axle
lifted up).
7.1.3. Lubrication and maintenance
schedule
NOTE: All intervals are counted from zero hours on
the hour recorder. For example, the 500 hours
service is carried out after 500, 1000 hours etc.
even if the measures have been carried out at the
guarantee service (=100 hours service).
Example: The 1000 hour service contains all items
mentioned under the 10 h/daily and the 50 hr
weekly checks as well as the 500 h service.
7.1.4.Service inspection (at 100 hours)
Your dealer gives this cost − free service inspection
(excluding oil and filter costs) after 100 hours
running to all new POLMOT tractors.
The following steps should be taken:
Engine
− Change engine oil and filter
− Change pre-filter of fuel system
− Change fuel filter
Power transmission
−
Change filter
Steering system and front axle
− Change oil in differential
− Change oil in planetary gears
Hydraulic system
− Change filter.
General
− Lubricate according to chart
− Road test tractor. During the road test check all
the functions of all the controls and instruments.
After the road test, check for oil leaks, check the
coolant and fuel system.
