Recommended Air Line Components
1. Incorporate an in-line oiler, shut-off valve, regulator with pressure gauge,
and lter for best service, as shown
in the diagram above. An in-line shutoff valve is an important safety device because it controls the air supply even if the air hose is ruptured.
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.
Attach an air hose to the 2. compressor’s air outlet. Connect the air hose to the air inlet of the tool. Other components, such as a connector and quick coupler (not included), will make operation more
efcient, 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
Page 7SKU 97956 For technical questions, please call 1-800-444-3353.
Page 8
the air tool to retain pressure and operate accidentally after the air supply is disconnected.
Note: Air ow, and therefore tool
performance, can be hindered by undersized air supply components.
The air hose must be long enough 3. to reach the work area with enough extra length to allow free movement while working.
Make sure the tool’s Trigger (19) is in 4. the off position; refer to “Components and Controls” section for description of controls. (See Figure A.)
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.
OPERATING INSTRUCTIONS
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.
Close the in-line safety valve between 5. the compressor and the tool.
Turn on the air compressor according 6. to the manufacturer’s directions and allow it to build up pressure until it cycles off.
Adjust the air compressor’s output 7. regulator so that the air output is enough to properly power the tool, but the output shall not exceed the tool’s maximum air pressure (90 PSI) at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range.
Inspect the air connections for leaks. 8. Repair any leaks found.
If the tool will not be used at this 9. 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.
Inspect tool before use, looking for damaged, loose, and missing parts. If any problems are found, do not use tool until repaired.

This Straight Line Mini Sander 1. uses PSA, 11” long x 2-3/4” wide Sandpaper.
To attach Sandpaper to the Pad (34) 2.
of the Mini Sander, rst wipe pad
surface face of dust and debris. Next remove the protective covering from the glued side of the Sandpaper. Then attach the glued side of the Sandpaper to the Pad. (See Figure
A.)
Work Piece and Work Area Set Up
Designate a work area that is clean 1. and well-lit. The work area must not allow access by children or pets to prevent injury and distraction.
Route the air hose along a safe 2. route to reach the work area without creating a tripping hazard or exposing the air hose to possible damage. The air hose must be long enough to reach the work area with enough extra length to allow free movement while working.
Secure loose workpieces using a vise 3. or clamps (not included) to prevent movement while working.
There must not be hazardous objects 4. (such as utility lines or foreign objects) nearby that will present a hazard while working.
Once the Straight Line Mini Sander 2. is connected to its air supply, and the compressor’s regulator is set at no more than 90 PSI, simply squeeze the Trigger (19) to turn on the tool. To turn off the tool, release pressure on the Trigger. (See Figure A.)
If the tool requires more force to 3. accomplish the task, verify that the
tool receives sufcient, unobstructed airow (CFM) and increase the
pressure (PSI) output of the regulator up to the maximum air pressure rating (90 PSI) of this tool.
CAUTION! TO PREVENT TOOL AND ACCESSORY FAILURE, RESULTING IN INJURY: Do not exceed the tool’s maximum air pressure rating (90 PSI).
If the tool still does not have sufcient
force at maximum pressure and
sufcient airow, then a larger tool
may be required.
To prevent accidents, once the job is 4. done, turn off the tool, detach the air supply, safely discharge any residual air pressure in the tool, and release the Trigger (19) after use. Clean external surfaces of the tool with clean, dry cloth, and apply a thin coat of tool oil. Then store the tool indoors out of children’s reach.
