OPERATION
Warming-up Operation
NOTICE
When the hydraulic oil is at a low temperature, do not carry out operations or move the lever suddenly. Always carry out the
warming-up operation. This will help to extend the machine life.
Do not suddenly accelerate the engine before the warming-up operation is completed.

After starting the engine, do not immediately start operations. First,
perform the following operations and checks.
1. Pull fuel control lever (1) from low idle (position A) to midway
position (B) between full speed and low idle to raise the engine
speed to a mid-range speed, then run under no load for approx.
5 minutes.

control lever close to the 1/4 position when carrying out the
warming-up operation.
