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 service life will be reduced. A new
machine must be operated with care, particularly 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.
If the machine is delivered without any cooling water in the radiator, flush the cooling
system with ample clean water to clean the system, then fill the radiator with cooling
water.
★When checking, adding or changing the cooling water, fuel or lubrication oil, be sure not
to let any dust or dirt get in.
★When replacing oil filters 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.
