Komatsu — BREAKING IN THE NEW MACHINE

INTRODUCTION BREAKING IN THE NEW MACHINE Each machine is carefully adjusted and tested before shipment. However, a new machine requires careful operation during the initial 100 hours as indicated by the service meter. 0 At the first 250 hours of operation, the machine should be maintained in the manner described in Section 3 “MAINTENANCE”. In addition: 1) Replace the transmission oil filter element. 2) Replace the engine oil filter cartridge and oil. 3) Check and adjust the engine valve clearance. 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. * 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. During breaking in: When replacing oil filters elements (cartridges), check their interiors for dirt and dust. If heavily collected, check for possible cause before starting operation. l After starting, let the engine idle for 5 minutes to allow proper engine warm-up prior to actual operation. * * Hours of operation are indicated by the service meter. l Avoid operation with heavy loads or at high speeds.

l Avoid sudden starts or acceleration, unnecessarily abrupt stops and sharp steering except in cases of emergency. o-3
