Product Usage Instructions

Material Consistency

1. Follow the material manufacturer’s recommendations for mixing.
2. Ensure that the material is thoroughly mixed and just thin enough to feed through the hopper
3. Do not thin the mixture to achieve a finer texture; instead, increase the air flow and select a smaller orifice.

Orifice Size

1. The circular orifice plate (2) on the front of the gun provides seven different orifice sizes.
2. Larger orifice openings will produce a coarser pattern than smaller openings.
3. To change the orifice, loosen the two knurled nuts (3,4).
4. Pull the trigger back and rotate the orifice plate to the desired size.
5. As you release the trigger, the orifice will be centered.
6. Finally, secure the orifice plate in position by first tightening the upper knurled nut and then the lower knurled nut.

Air Flow

1. The air flow at the gun is adjusted by the ball valve-air line coupler (15).
2. A reduced air flow will produce a coarser texture while a greater air flow will produce a finer texture.
3. The higher the air pressure, the finer the pattern; the lower the air pressure, the coarser the pattern.
4. Do not set the air flow too high, as this can cause waste and mess.

Trigger Setting

1. Set your pattern on scrap sheetrock or cardboard before spraying your finished product.
2. Experiment with various adjustments to obtain your desired texture.
3. Note the compound consistency, orifice, air pressure at the compressor, relative ball valve position, and trigger setting for future reference.

Maintenance

1. Keep the gun and hopper clean for best results.
2. Separate the gun and hopper and flush each with clean water.
3. The front and rear bushings (12, 22) are permanently lubricated; re-oiling is normally not necessary.

Replacement Parts

Built-in Handle

The Sharp Shooter Drywall Hopper Gun has a built-in handle for solid grip and good control during usage.

PRODUCT OPERATION, INSTRUCTION INFORMATION

The SharpShooter® 1 Drywall Hopper Gun, together with an air compressor, will apply most any sprayable material that can feed by gravity through the hopper and that can fit through one of the holes in the orifice plate. The texture that results can be adjusted in four ways.

Material Consistency
Follow the material manufacturer’s recommendations for mixing. It is important that the material be thoroughly mixed and be just thin enough to feed through the hopper. This enables the droplets of spray to stay on the wall/ceiling surface and form a good texture. Do not thin the mixture to achieve a finer texture, rather increase the air flow and select a smaller orifice.
Orifice Size
The circular orifice plate (2) on the front of the gun provides seven different orifice sizes. Larger orifice openings will produce a coarser pattern than will a smaller opening. To change the orifice, loosen the two knurled nuts (3,4). Pull the trigger back and rotate the orifice plate to the desired size. As you release the trigger the orifice is centered. Finally, secure the orifice plate in position by first tightening the upper knurled nut and then the lower knurled nut.

Air Flow
The air flow at the gun is adjusted by the ball valve-air line coupler (15). A reduced air flow will produce a coarser texture; a greater air flow will produce a finer texture. The higher the air pressure, the finer the pattern; the lower the air pressure, the coarser the pattern. If the air flow is too great, however, the grains within the mixture can separate from the mixture and rebound off the walls. This can lead to waste and mess.

Trigger Setting
The position of the trigger controls the amount of material flow. As the trigger is pulled back, more material is allowed to feed through. Generally the distance between the air nozzle (25) and the mixture nozzle (5) should be slightly greater than the size of the selected orifice. When the desired texture is achieved, the trigger position can be set by tightening the wing- nut (16). This will ensure the needle is pulled back the same distance each time so that the texture remains consistent. Releasing the trigger stops the material flow.
It is recommended that you set your pattern on scrap sheetrock or cardboard before spraying your finished product. By experimenting with the various adjustments you should be able to obtain your desired texture. Note the compound consistency, orifice, air pressure at the compressor, relative ball valve position, and trigger setting for future reference.

MAINTENANCE

It is important to keep the gun and hopper clean. For best results, separate the gun and hopper and flush each with clean water. The front and rear bushings (12, 22) are permanently lubricated; re-oiling is normally not necessary.

REPLACEMENT PARTS

Refer to the illustration for part numbers and proper assembly. Replacement parts may be ordered individually, or are available in the MARSHALLTOWN No. RK696 Repair Kit. The RK696 Repair Kit contains the orifice plate, knurled nut, center knob, rubber boot, trigger, transfer bar, mixture nozzle, and E-clip retainer.
When re-assembling the gun, use a silicone sealant* between the housing halves to prevent the spray material from leaking to the trigger mechanism.

• Not included, purchase separately.
