Air Filter - Protects engine by filtering dust and debris out of intake air.

Thermal Relief Valve - Cycles cool water through pump when water reaches 140°F. Warm water

will discharge from pump onto ground. This system prevents internal pump damage.

Automatic Pressure Relief Valve (APR) - Eliminates pressure in the pump while starting the

engine making the unit to start easier

Chemical Injection Siphon/Filter - Use to siphon detergent or other pressure washer chemicals

into the low pressure stream.

Choke Lever - Prepares a cold engine for starting.

Data Plate - Provides model, revision and serial number of pressure washer. Please have these

readily available if calling for assistance.

Fuel Tank - Fill tank with regular unleaded fuel. Always leave room for fuel expansion.

Fuel Valve - Used to turn fuel on and off to engine.

High Pressure Hose - Connect one end to the water pump and the other end to the spray gun.

High Pressure Outlet - To connect high pressure hose.

Nozzle Extension with Quick Connect - Allows you to switch between four different spray tips.

Oil Fill Cap - Fill engine with oil here.

Pump - Develops high pressure.

Recoil Starter - Use for starting the engine manually.

Safety Goggles (not included) - Always use safety goggles or other eye protection when running

your pressure washer.

Gunvalve - Controls the application of water onto cleaning surface with trigger device. Includes

safety latch.

Spray Tips - 0°, 15°, 25°, 40°, and Chemical

Throttle Lever - Sets engine in starting mode for recoil starter and stops a running engine.

Water Inlet - Connect garden hose here

Frame - Supports the key working components of the machine.

Overpressure Valve - Designed to safely relieve system pressure in the case of unloader

malfunction

Unloader Valve – Allows the pump to “by-pass” water through the pump when the gunvalve

trigger is released. This allows the engine to continue to run when not spraying water.

Wheels – Enable pressure washer to be transported around work area and provide vibration

absorption to minimize wear on mechanical components

Belt Drive - Belt driven units use pulleys and belts to slow the speed of the pump. This system

ensures longer pump life over direct drive pumps of similar quality.

Belt Cover – Safety device to provide protection from moving components of belt drive system.

Under no circumstances should the pressure washer be operated without the belt cover securely in place.

Select the cleaning nozzle or accessory best suited for the cleaning job. NOTE: Some accessory nozzles function as both a high pressure cleaning nozzle and low pressure chemical injector nozzle (i.e. vari-tip nozzles). See specific accessory nozzle operating instructions for more information. 2.
