BREAKING IN YOUR NEW MACHINE
BREAKING IN YOUR NEW MACHINE
Each machine is carefully adjusted and tested before shipment. However,
a new machine requires careful operation during the first 100 hours to
break in the various parts.
If a machine is subjected to unreasonably hard use at the initial operation
stage, the potential of performance will prematurely deteriorate and the ser-
vice life will be reduced. A new machine must be operated with care, partic-
ularly with regard to the following items.
After starting, let the engine idle
for 5 minutes to allow proper
engine warm-up prior to actual
operation.
Avoid operation with heavy loads
or at high speeds.
Sudden starting or acceleration,
unnecessarily abrupt braking and
sharp turning should be avoided.
l
At the first 250 hours of *
operation, the machine should be
maintained in the following
manner in addition to usual 250
hours service:
I) Replacement of fuel filter car- *
tridge and transmission oil filter
element
2) Checking and adjustment of
engine valve clearance
For replacement procedure and
details, see maintenance table in
the maintenance section.
When replacing oil filter elements
(cartridges), check their interiors
for dirt and dust. If heavily
collected, check for possible
cause before starting operation.
Hours of operation are indicated
by the service meter.
