Operation
The ratchet wrench must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) in to
the air inlet.
2.
Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90psi.
IMPORTANT:
Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
3.
Push drive socket (not included) onto anvil
until it clicks into position.
4.
Select forward (F) or reverse (R) rotation on
the direction switch.
Make sure nut or bolt can
withstand rated torque of ratchet wrench.
To loosen nut or bolt:
1.
Select reverse rotation.
2.
Place socket over nut, and grip tool firmly
with both hands.
3.
Gently squeeze throttle lever. Pressure
against throttle lever determines speed of
ratchet wrench.
Important:
If tool cannot loosen nut, DO
NOT raise air pressure above 90 psi. Use
other methods or tools to loosen nut.
4.
Release throttle lever to stop ratchet wrench.
To tighten nut or bolt:
1.
Install nut as far as possible by hand.
2.
Select forward rotation.
3.
Place socket over nut, and grip tool firmly
with both hands.
4.
Gently squeeze throttle lever. Pressure
against throttle lever determines speed of
ratchet wrench.
Important:
If tool stalls while tightening, DO
NOT raise air pressure above 90 psi. If nut
will not tighten, do not continue attempts to
tighten nut with the ratchet wrench. Use
other methods or tools to tighten nut.
5.
Release throttle lever to stop ratchet wrench.
NOTE: Do not overtighten. Fasteners with critical
torque settings should be fully tightened with a
torque wrench.
Maintenance
Lubrication
The ratchet wrench should be lubricated
daily
(or
before each use) with air tool oil through the air
inlet. During continual operation, it should be re-
oiled every 1 to 2 hours. This can be done with an
in-line oiler, or manually. If done manually,
proceed as follows:
1.
Disconnect air hose from tool.
2.
Place 4 or 5 drops of air tool oil into air inlet.
