Pneumatic Tool Usage - Husky 671-049 Operator's Manual

ASSEMBLY OF AIR TOOL
Apply thread tape to threaded connections of 1/4" NPT male
plug, attach male plug to hose with a wrench (wrench and 1/4"
NPT male plug are not provided).
Ensure regulator of compressor is adjusted to minimum posi-
tion if a compressor is used and ensure outlet pressure is near
zero.
Attach 1/4" NPT male plug of tool to female couple end of air
hose.
LUBRICATION OF AIR TOOL
1/2" Impact Wrench
Impact wrenches require lubrication throughout the life of the
tool and must be lubricated in two separate areas: the air mo-
tor and the impact mechanism. Follow the outlined procedures
and refer to parts manual for tool features.
WARNING
Disconnect the impact wrench from the air supply
before lubricating.
AIR MOTOR LUBRICATION
The motor must be lubricated daily. An air motor cannot be
oiled too often.
1. Disconnect the impact wrench from the air supply.
2. Turn the impact wrench upside down.
3. While pulling the trigger, squeeze approximately a 1/4 oz. of
air tool oil in the air inlet. Then, push the forward and reverse
button in both directions.
4. Connect the impact wrench to the air supply and cover the
exhaust port with a towel (Refer to replacement parts manual
for tool features). Run the impact wrench in both the forward
and reverse directions for 20 to 30 seconds. Oil will discharge
from the exhaust port when air pressure is applied.
WARNING
After an air tool has been lubricated, oil will
discharge through the exhaust port during the first
few seconds of operation. Thus, THE EXHAUST
PORT MUST BE COVERED WITH A TOWEL before
applying air pressure. FAILURE TO COVER THE
EXHAUST PORT CAN RESULT IN SERIOUS
INJURY.
IMPACT MECHANISM LUBRICATION
Lubricate the impact mechanism monthly.
1. Disconnect the impact wrench from the air supply.
2. Remove the slotted screw or allen head screw from the oil
port hole (Refer to replacement parts list for tool features).
3. Squeeze approximately 1 oz. of air tool oil in the oil port
hole. Replace the screw.

PNEUMATIC TOOL USAGE

4. Reconnect the air supply to the impact wrench and run for
20 to 30 seconds. Lubricate the entire impact mechanism
by rotating the tool upside down and sideways while
running the tool.
5. Remove the screw and hold the oil port hole over a suitable
container to allow excess oil to drain. Sometimes triggering
the tool when dumping the oils helps to force out the excess
oil.
6. If the oil is dirty, repeat the procedure above until the oil
comes out clear. Install the screw and tighten. The residual
oil remaining in the impact mechanism chamber is all that is
needed for proper lubrication.
3/8" Ratchet Wrench
Ratchet wrench requires lubrication before the initial use and
before and after each additional use.
1. Disconnect air supply.
2. Pour about 1/4 teaspoon of air tool oil into air inlet.
3. Operate trigger lever to allow oil to enter air motor.
4. Connect the air tool to the air supply and cover the exhaust
port with a towel. Run the air tool for 7 to 10 seconds. Oil
will discharge from the exhaust port when air pressure is
applied.
