3-7-2 INSPECTION OF NITROGEN GAS PRESSURE
1. Place the hydraulic breaker about 50cm
(1.64ft) from the ground in a horizontal
position for easy access.
Stop the excavator engine.
2. Remove the gas valve plug (1) from the cylinder cover.
P.S : In regard to the side mount silenced bracket remove the bolt（4） and turn over the cover (5）
and continue the work process of 2.
3. Insert a pressure gauge (A) into the gas
valve (2) and measure the nitrogen gas
pressure
Filling nitrogen gas pressure at usual
atmosphere temperature （ 40 ℃）
◆Refer to the attached graph when the breaker body temperature is lower than
40℃ (104F).
