driving toolcan be safelyfixed for the intended use,thus forexample avoiding damage,
distortion or displacement.
9. Fastener driving tools operated bycompressed air shall only be connected to compress-
ed air lines where the maximum allowable pressure cannotbe exceed by a factorof
more than 10%, which can for example be achieved by a pressure reduction valve
which includesa downstream safetyvalve.
10. When using fastener driving tools operated bycompressed air,particular attention must
be paid to avoid exceeding the maximum allowable pressure.
11. When using fastener driving toolsoperated by compressed air should onlybe operated
at the lowest pressure required for the workprocessat hand, in order to prevent unnece-
ssarilyhigh noise levels, increased wear and resulting failures.
12. Hazards caused by fire and explosion when using oxygen or combustible gasesfor ope-
rating compressed airoperated fastener driving tools.
13. Carry the fastenerdriving tool atworkpiece using onlythe handgrip,and never with the
trigger actuated. Never carrythe tool by the hose orpull the hose to move the tool.

AIR SUPPLY AND CONNECTION
NOTE
•Many airtool usersfind it convenient to use oilerto help provide oil
circulation through tool and increase the efficiencyand useful life of
the tool. Check oil level in the oiler daily.
•Many airtool user find itconvenient to use a filterto remove liquid
and impurities which can rust or wear internal parts of the tool. A
filter also increase the efficiency and usefulof the tool.The filter
must be checked on a dailybasis and if necessary drained.
•For better performance, install a 3/8" quick connector (1/4" NPT
threads) with an inside diameterof .315" on yourtool and a 3/8"
quick coupler on the air hose.
The following illustration shows the correct mode of connection to the air
supply system which will increase the efficiency and useful life of the tool.
LUBRICATION AND MAINTENANCE
NOTE
•Disconnect the air supplyfrom the toolbefore lubricating.
•Your tool requires lubrication before you use it for the first time.
•Wipe off excessive oil at the exhaust. Excessive oil will damage
O-ringsof tool. If in-line oiler is used, manual lubrication through the
air inlet is not required on a daily basis.
•Turn the tool so the inletis facing up and put one drop ofhigh
speed spindle oil,UNOCAL RX22, or 3-IN-1 oil into airinlet. Never
use detergent oil or additives. Operate the tool briefly after adding
oil.
