gine.

6.
Depress the brake pedal several times.
After the brake pedal is depressed some times, the brake
oil pressure caution lamp (1) lights up.
• If the brake oil pressure caution lamp lights up when
the brake pedal is depressed 4 times or less, the gas
pressure in the accumulator may be low. Ask your Ko-
matsu distributor for inspection.
• If the brake oil pressure caution lamp does not light up
when the brake pedal is depressed 5 times, the gas
pressure in the accumulator is normal.
REMARK
Check the function within 5 minutes after stopping the en-
gine.
If the engine is kept stopped, the gas pressure in the accu-
mulator lowers and cannot be checked.
7.
After checking, turn the starting switch to OFF position (A).
