Specifications; Lubrication - Craftsman 9-19905 - 1/2dr 1/4npt 500ft/lb Sq Dr Impact Wrench Owner's Manual

Your
Impact Wrench incorporates
a Power Management System that
allows you to select four power
output settings. These settings
range from minimum power output
through maximum power output in
the forward direction only. The Air
Wrench will always operate at
maximum power output in the re-
verse direction, no matter what
power output level is selected.
AWARNING:
The four power setting indicators
of increasing size on the rear of
the housing are for reference only
and DO NOT denote a specific
power output. The smallest power
setting indicator designates mini-
mum power output, the two middle
power setting indicators denote
medium power outputs and the
largest power setting indicator de-
notes maximum power output.
The power output can be further
reduced in forward or reverse by
using the variable throttle. Air sup-
ply systems which do not deliver
adequate air pressure can affect
power output at all settings.
