Product Installation

CAUTION:

1. ONLY Fit 1'' Shaft Horizontal Engines.

2. With a 3/8" quick plug, if it is not suitable for the connector of your PRESSURE WASHER HOSE, please purchase the adapter coupler connection separately.

3. In order to protect the spring, the pressure is not set to the maximum value at the factory, please adjust the pressure with the regulator.

4. Only suitable for COLD WATER use.

Some Tips To Choose The Compatible Replacement Pump:

1. Match Engine Orientation.

Horizontal Engine: The pump is installed horizontally onto the engine.
Vertical Engine: The pump is installed vertically below the engine.

2. Match your machine's PSI And GPM.

Engine power and pump performance need to be matched for optimal machine performance.

3. Match the Engine Shaft Diameter.

The shaft diameter for vertical pumps is typically 7/8 inches. The shaft diameter for horizontal pumps is either 3/4 inches or 1 inch.

4. Match Current Pump Outlet Connection.

This will ensure that your attachments are compatible with the new pump.
