Grounding

AWARNING TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION: Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Double Insulated Tools: Tools with Two Prong Plugs

Figure A: Outlets for 2-Prong Plug

1. Tools marked "Double Insulated" do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.

2. Double insulated tools may be used in either of the 120 volt outlets shown in the preceding illustration. (See Figure A.)

3. This appliance has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

Extension Cords

1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.

2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)

3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)

4. When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Table A.)

5. If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)

Table A: Recommended Minimum Wire Gauge for Extension Cords* (120/240 Volt)

* Based on limiting the line voltage drop to five volts at 150% of the rated amperes.

Spraying Technique

When first filled, the sprayer may take up a short time after the trigger is depressed to prime and start spraying.

IMPORTANT: Proper spraying technique is ESSENTIAL to achieve good results.

1. First, prepare the Spray Gun according to the instructions under Spray Gun Setup and Adjustment on page 12.
2. Keep the Spray Gun upright and at a right angle to the workpiece - See Figure B.

Correct Gun Angle

Move your arm, not just your wrist. Point gun directly towards the surface and maintain an even, steady distance and speed.

Incorrect Gun Angle

Do not pivot your wrist or wave the gun like a fan towards the wall.

NOTICE: Do not stop when spraying. Spraying materials will start to set and dry as soon as they come in contact with the air. To avoid clogs, check Nozzle regularly for dried paint and remove with a cloth as needed.

3. Depress Trigger fully and move Spray Gun in parallel strokes to the workpiece.
4. Keep the distance from the workpiece between 2" and 12".
5. To avoid paint build up:
   1. Apply two thin coats rather than one thick coat. Overlap 1/3 to 1/2 on second coat.
   2. Start moving the Spray Gun before fully depressing Trigger.
   3. Fully depress Trigger before contacting the workpiece.
   4. When finished with the stroke, release the Trigger while still moving the Spray Gun and after passing the workpiece - see Figure C.

Note: Doing this will produce a smoother finish. Do not stop moving the Spray Gun while spraying. If the Spray Gun stops even briefly while spraying the paint will build up and run down the workpiece.

Note: The stroke speed and Fluid Control Knob adjustment will determine how much paint is being applied.

6. Keep Cup filled half-way full to prevent spattering. When refilling, loosen Lid first to release pressure.
7. To prevent accidents, after use, release Trigger, unplug the tool, safely discharge any residual air pressure, and release Trigger again.
8. Clean Spray Gun and Cup IMMEDIATELY after EVERY use and when it will be idle for more than 30 minutes. Delayed or inadequate cleaning will permanently clog the Spray Gun.
