INSTALLATION

Selecting air hose
CAUTION:
Low air output of the compressor,
or a long or smaller diameter air hose in rela-
tion to the screwdriving frequency may cause a
decrease in the driving capability of the tool.
Use a high pressure resistant air hose. Use an air hose
as large and as short as possible to assure continuous,
efficient screw-driving operation.
► Fig.2
Lubrication
Before and after use, apply two or three drops of pneu-
matic tool oil into the air fitting. After applying the oil,
connect the air hose and drive some screws for proper
lubrication.
