Set the saw frame on a stand or table. Face the back of the saw towards an open area.
Place the wet tile saw's water trough on the frame. The trough has two runners for the wet saw trey to ride on and stores the water for the wet tile saw to use.
Close the drain plug, usually located at the rear of the trough.
Set the wet tile saw's pump in the back of the trough. Connect the plastic tube from the pump to the blade housing's water ports. The blade housing water ports extend from the rear of the housing.
Fill the trough with water from a bucket. The water should rise to the bottom of the trey runners.
Place the trey on the runners located in the trough. Some models have four wheels under the trey that ride on the runners, other models have two wheels and a rail. Push the trey back and forth to verify the trey does not make contact with the blade.
Plug the wet tile saw into an electrical outlet. Extension cords should have the smallest possible length and use at least a 10-gauge wire.
Turn the power switch on. Allow water to circulate through the pump and onto the diamond blade.
Stand in front of the wet tile saw and pull the trey to the front of the trough. Place a tile on the trey. Hold the back of the tile still with both hands.
Push the tile to the blade. Apply light pressure to the trey as the blade cuts the tile. Do not force the tile.
Place a hand on each side of the tile as the blade cuts through the tile. This will eliminate vibration. Excessive vibration will break the tile.
Slow the cutting speed as the blade reaches the end of the cut. Forcing the tile here will cause the corner to break.
Layout a curved cut on a piece of tile with a pencil. Make a series of straight cuts with the wet tile saw from the tile's edge to the pencil mark. These cuts should have a 1/2-inch space between them. Tap the 1/2-inch slivers with a hammer, breaking them free. Trim the cut tile with the wet tile saw along the pencil line.
