Note: A small Inflator (32) accessory comes with this unit. To fill a raft or air mattress, attach the inflator as shown in FIGURE 2 on page 11. When the inflator is attached to the object being inflated, start the unit using the Switch (31). Turn off the unit when the object is inflated. Read the instruction manual of the object to be inflated to determine the recommended and maximum PSI for filling the object. You will have to check the air pressure of the object by using a separate air pressure gauge (not included). Do not overinflate. Overinflating may cause the object to explode.

INSPECTION, MAINTENANCE, AND CLEANING

1.WARNING! Make sure the Power Switch (31) of the Motor Unit is in its “OFF” position and that the tool is unplugged from its electrical outlet before performing any inspection, maintenance, or cleaning procedures.

2.BEFORE EACH USE, inspect the general condition of the Sprayer. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring, and any other condition that may affect its safe opera- tion. If abnormal noise or vibration occurs, have the problem corrected before further use. Do not use damaged equipment.

3.After each use, clean the gun immediately. Open the Cup Cover (19) and remove the Paint Cup (24). Replace left over paint in its container and seal the container. Pour small amounts of thinner into the Paint Cup (24) and replace the Cup Cover (19). Fire the Spray Gun into a paint waste receptacle until the thin- ner comes out completely clean. Repeat if necessary. Clean off any trace of paint from the Spray Gun. Clean off the Gasket (20) that is under the Cup Cover (19).

4.Clean the Fluid Nozzle (15) and the Fluid Needle (4). First, unlock and remove the Lock Ring (17), and Fluid Tip (16). Completely loosen the Fluid Needle Screw

(1). Remove the Needle Spring (2) and push out the Fluid Needle (4). Do not use tools as they will bend the part. Put the parts in a container with thinner and clean them. Replace them in the proper order. Refer to the Assembly Drawing on page 15.

5.Run water through the Spiral Air Hose (46) making sure it is clean inside. Discon- nect the Spiral Air Hose from spray gun or inflator and the motor unit, then allow it to dry before reassembly.

6.Make sure the Gasket (20) on the Paint Cup (24) is not torn or broken. If it is, replace it immediately. Always make sure the Gasket (20) is on correctly.
