● 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 attach-
ments, bolts and nuts might have been heated up after operation.
■ Other precautions
● Do not touch the oil plug except for repairing.
It can cause early oil leakage.
● Using a tool which has been in storage for more than
6 months may cause oil leakage because of damage
to the seal part on the impulse mechanism.
When putting the tool in storage for a long period, be sure
to make the periodical maintenance, running the tool with
load every 6 months in order not to stick the seal part to
other component part. We can offer the inspection service.
Please ask us for the service.
● Be sure to do warm-up operation with a tool for about
10 seconds by putting a main shaft under load in cold
weather region or at the beginning of the shift in
winter season.
Also note there may be a possibility of getting slip phenom-
enon (no pulsing).
※
Recommended temperature to be used:
５℃〜４０℃
● Long socket, larger sockets and so forth will cause
the slipping phenomenon.
