stop the engine before performing any inspection and main-
tenance.

work equipment control lever back and forth, left and right at
the full stroke 2 to 3 times to eliminate the remaining inter-
nal pressure in the hydraulic circuit. Move lock lever (1) to

position.

conducted. (After turning off the starting switch, wait for
approximately 1 minute and press the horn switch. If the
horn does not sound, power is not conducted.)
