Be prepared for reaction force

Be prepared for reaction force by holding the tool securely 
since there is a chance that an operator might be pushed 
around by the reaction force.

Be careful with the operation of a tool at no load.

When running the tool at no load, be sure that the tip tool 

was removed without fail and be careful about the 

surroundings. The operation at no load for a long time will 

be the reason for the part breakdown with seizure, early 

wear and so on.

Be careful of burn injury.

Make sure not to touch attachments carelessly because 

attachments, bolts and nuts might have been heated up 

after operation.

Do not give the impact externally.

Be careful since the electronic parts are used in the follow-

ing units: Cover plate, Electric buzzer, Connector of the 

connecting cable, Inside of hammer case.

Check the torque periodically by the torque wrench 

after tightening the bolt, nut etc.
About the controller

Be careful against the chemicals and water. 

Especially the intrusion of water  to the inside of the control-

ler may cause the short circuit.

Do not put more load than specified to the relay 

output terminals.

Install  the proper surge killer near the load in parallel 

in case that the controller malfunctions owing to the 

surge(noise) during the usage of the output terminals.

In case that the controller has the built-in battery, 

exchange it periodically.
