Lubrication
Air tools require lubrication throughout the lifetime of the tools.
This power tool uses compressed air as a power source. The compressed air contains moisture that will rust the
components inside of the tools, therefore lubrication is required daily. Failure to lubricate the air tool properly
will dramatically shorten the life of the tool and will void the warranty
CAUTION:
This air tool requires lubrication
BEFORE
initial use, also before and after each additional use.
To lubricate the air tool manually:
1. Disconnect the tool from the air supply source, place the air inlet face up.
2. Depress the trigger and place about 5 to 10 drops (0.25 to 0.5 ml) of air tool oil into the air inlet.
NOTE: Use SAE #10 weight oil if air tool oil is not available.
3. Remove accessory, connect the tool to an air source, then cover the
exhaust end with a towel and run tool for 2 to 3 seconds.

To lubricate internal mechanism:
Locate the grease fi tting on the back of the tool (fi g. 4). Inject 4 grams
of Mac Tools approved impact grease into the fi tting every 3-5 months
depending on use. Use recommended grease gun nozzle tip (fi g. 5) on
grease fi tting, smaller or sharp nozzle will damage grease fi tting ball bearing.

WARNING
:
Keep out of the reach of children. If air tool oil is
ingested, do not induce vomiting, call a doctor immediately.
WARNING
:
Any excess oil in the tool is immediately expelled from the
exhaust port. Always direct exhaust port away from people or objects.
NOTE: Check the speed and make a simple check of the vibration level
after each service.
Storage:
The air tool must be lubricated before storing. Follow the
“Lubrication” instruction with exception of step 3.
Always use an air line lubricator with this tool. Do not over-oil and do not use heavy grade oil as stalling and low
performance may result.
PLACING TOOL IN SERVICE
An air fi lter unit should be
placed between air com-
pressor and air lubricator to
promote clean air supply to
the impact wrench. Water,
dirt, and scale can damage
the impact wrench.
