DNPB328 Operation Manual
TOOL MAINTAINANCE
In order to maintain optimum performance after several weeks of regular use, add a few drops
of hydraulic oil to the inlet of the
air adaptor (#58)
of the tool in order to reduce the friction of the
tool parts since the oil will be blown inside the tool when tool is in operation.
After a period of use, the tool stroke may be reduced which indicated that the hydraulic oil in the
pneumatic tool needs to be refilled or changed;
1) Remove the
screw (#17)
with a hexagon wrench:
2) Connect the air supply and to place a cloth over the hole where the
screw (#17)
was
removed, then to pull the
trigger (#53)
and the oil will be forced out from the tool
3) Screw the
oil inject adaptor (in oil injector set in the accessories pack)
into the hole where
screw (#17)
was removed;
4) Use the
oil injector (in the accessories pack)
to slowly inject the oil until full (approx. 15ml).
Remove the injector and its adaptor, then clean off any excess oil on the tool and tightly
screw the
screw (#17)
back into the tool;
