G 1. 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.
G 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.
NOTE: 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. Waste oil and oil
filters should be handled carefully and disposed of
properly.
--- 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.
G 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).
G 1.3. Lubrication and maintenance
schedule
NOTE: All intervals are counted from zero hours on the
hour recorder. For example, the 250 hours service is
carried out after 250, 500 hours etc. even if the
measures have been carried out at the guarantee
service (=100 hours service).
Example: The 500 hour service contains all items
mentioned under the 10 hr/daily and the 50 hr/weekly
checks as well as the 250 hr service.
G 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 Valtra tractors.

road test, check for oil leaks, check the coolant and fuel
system.
