Air Supply

TO PREVENT SERIOUS INJURY

FROM EXPLOSION:

Use only clean, dry, regulated, compressed

air to power this tool. Do not use oxygen,

carbon dioxide, combustible gases, or any other

bottled gas as a power source for this tool.

1. Incorporate a filter, regulator with pressure gauge,

oiler, in-line shutoff valve, and quick coupler for

best service, as shown on Figure A on page 6

and Figure B on page 7.

An in-line shutoff

ball valve is an important safety device because

it controls the air supply even if the air hose

is ruptured. The shutoff valve should be a

ball valve because it can be closed quickly.

Note: If an automatic oiler system is not used,

add a few drops of Pneumatic Tool Oil to the

airline connection before operation. Add a few

more drops after each hour of continual use.

2. Attach an air hose to the compressor’s air outlet.

Connect the air hose to the Air Valve Assembly (5)

of the Bottle Jack. Other components, such

as a connector and quick coupler, will make

operation more efficient, but are not mandatory.

WARNING! TO PREVENT SERIOUS INJURY

FROM ACCIDENTAL OPERATION:

Do not install a female quick coupler on the tool.

Such a coupler contains an air valve that will

allow the air tool to retain pressure and operate

accidentally after the air supply is disconnected.

Note: Air flow, and therefore tool performance, can

be hindered by undersized air supply components.

The air hose must be long enough to reach

the work area with enough extra length to

allow free movement while working.

3. Turn the tool’s throttle or switch to the off position;

refer to Operation section for description of controls.

4. Close the in-line shutoff valve between

the compressor and the tool.

5. Turn on the air compressor according to

the manufacturer’s directions and allow it

to build up pressure until it cycles off.

6. Adjust the air compressor’s output regulator

so that the air output is enough to properly

power the tool, but the output will not exceed

the tool’s maximum air pressure at any time.

Adjust the pressure gradually, while checking the

air output gauge to set the right pressure range.

7. Inspect the air connections for leaks.

Repair any leaks found.

8. If the tool will not be used at this time, turn off

and detach the air supply, safely discharge any

residual air pressure, and release the throttle

and/or turn the switch to its off position

to prevent accidental operation.

Note: Residual air pressure should not be present

after the tool is disconnected from the air supply.

However, it is a good safety measure to attempt to

discharge the tool in a safe fashion after disconnecting

to ensure that the tool is disconnected and unpowered.
