The hammer is equipped with a built-in Ramvalve (check the part number (X) from
the parts manual).
The Ramvalve is designed to decrease oil flow remarkably to the hammer when oil
flow from the carrier is too high.
If the impact rate of the hammer decreases suddenly when operating the hammer,
contact your local carrier dealer to decrease the carrier's oil flow.
The hammer can be equipped with an automatic greasing device. The tool grease is
supplied from the greasing device into the hammer by the grease lines. See
“Automatic greasing” on page 41.
Advantages of the automatic lubrication system are:
Longer service life for wear parts
Higher utilization rate of the hammer
Possibility to grease manually
Reduced grease waste
Note: Some hammer models are equipped with an adapter kit for manual greasing
and do not include an automatic greasing device.
