Lx410/450/490 Operator's Manual
The service life of the tractor is determined
by how well the tractor is operated and maintained.
Prior to delivery, the tractor has been fully tested to
ensure that the tractor is operating normally. The
manner the tractor is operated during the breaking-in
period greatly affects the effective life of the tractor.
To bring about optimal tractor performance and to
achieve the longest tractor life, various parts of the
tractor have to be properly broken-in.
The following practices must be observed.
●
Operate the tractor at low speeds for the first 50
operating hours.
●
Avoid heavy operations and loads.
●
Strictly observe the following instructions
explained below.
■
Always run the tractor at less than full
speed during the first 50 hours of
operation
●
Always start and brake the tractor slowly.
●
In cold weather, always fully warm up the engine
before operating the tractor.
●
Avoid under any circumstances running the
engine at a speed higher than needed.
●
On rough roads or terrains, drive at low speeds.
■
Change the lubricating oil for the new
tractor
The quality of the lubricating oil in any new tractor is
very important. Parts not fully broken-in may not yet
perfectly fit with each other.
Small metal shavings can be created during
operation of a new tractor. The shavings can lead to
premature wear or damage to tractor parts.
Yanmar recommends changing the lubricating oil
earlier than the standard oil change schedule.
For the recommended oil change schedule, for
details, see "Chapter 13. MAINTENANCE" on page
13-1.
1. Operate a New Tractor
NOTE
●
The preceding practices should also be adopted
for all tractors regardless of age to prevent
premature tractor breakages and accidents.
