lubrications
Frequent, but not excessive, lubrication is required for best
performance. Oil added through the air line connection
will lubricate the internal parts. Do not use detergent oil or
additives as these lubricants will cause accelerated wear
to the seals and bumpers in the tool, resulting in poor tool
performance and frequent tool maintenance.
If no airline lubricator is used, add oil during use into the
air fitting on the tool once or twice a day. Only a few drops
of oil at a time is necessary. Too much oil will only collect
inside the tool and will be noticeable in the exhaust cycle.

ASSEMBLY AND ADJUSTMENTS


WARNING: To reduce the risk of serious personal
injury, turn unit off and remove air supply before
making any adjustments or removing/installing
attachments or accessories. An accidental
actuation can cause injury.
