Hitachi’s own internal pressure adjustment mechanism
An air passage is provided as shown below to let out air inside the gear cover and let outside air in the gear
cover. This passage is sandwiched between felt packings to allow only air to pass. As a result, fluctuations
in internal pressure are minimized for stable hammering operation and preventing grease leakage.
