SETUP

Work Piece and Work Area Set Up

1.  Designate a work area that is clean and well-lit.  

The work area must not allow access by children 

or pets to prevent distraction and injury.

2.  Route the air hose along a safe 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.

3.  Secure loose workpieces using a vise or clamps 

(not included) to prevent movement while working.

4.  There must not be hazardous objects 

(such as utility lines or foreign objects) nearby 

that will present a hazard while working.

General Operating Instructions

1.  If an automatic oiler is not used, add a few 

drops of Pneumatic Tool Oil to the airline 

connection before use.  Add a few drops 

more after each hour of continual use.

2.  Install a sheet of sandpaper onto the Sander.

3.  Connect the Sander to the air compressor’s 

hose. If leaking is detected, disconnect 

the air hose and repair before use.

4.  Firmly grip the Handle with one hand 

and the Knob with the other hand.

5.  Depress the Trigger before making contact 

with the work surface to ensure the Inline 

Sander does not jump from your hands.

6.  Move the Inline Sander along the work 

surface  in a smooth steady motion. 

Keep the sander moving from side to side to 

avoid sanding a pattern into the work surface. 

Note:

  Do not put too much pressure on the 

Inline Sander while sanding. Let the weight of 

the tool do the work. If the Inline Sander stalls 

during use, release the Trigger immediately.

7.  If the tool requires more force to accomplish 

the task, verify that the tool receives sufficient, 

unobstructed airflow (CFM) and increase the 

pressure (PSI) output of the regulator up to the 

maximum air pressure rating of this tool.

CAUTION!  TO PREVENT INJURY FROM 

TOOL OR ACCESSORY FAILURE: 

Do not exceed the tool's  

maximum air pressure rating.

 

If the tool still does not have sufficient force 

at maximum pressure and sufficient airflow, 

then a larger tool may be required.

8.  To prevent accidents, turn off the tool, detach the air 

supply, safely discharge any residual air pressure 

in the tool, and release the Trigger 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.
