installation & preparation

unloader:

The unloader has been preset at the factory.

Heat dump ValVe:

To ensure the water temperature does not exceed acceptable levels, never allow
the pressure washer to operate in the bypass mode (with the unit running and
the trigger closed) for more than three minutes.
A heat dump valve has been added to this unit to protect the pump. It may begin
to open and release water if the water temperature in the pump has exceeded
40° F. This will allow fresh, cool water to enter the system, therefore preventing
premature failure of pump packings.

pre-start inspection procedures:

Before starting the unit, perform the following procedures:
. Check the oil level in the pump and engine.
2. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply", #2, pg 3.
3. Check all hose connections to ensure they are securely tightened. See
"Water Supply", #3, pg. 3.
4. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See "Risk of Explosion or Fire", pg. 4. Be
sure that all damaged parts are replaced and that the mechanical problems
are corrected prior to operation of the unit. If you require service, contact
Customer Service.
5. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is
found, DO NOT USE HOSE! Replace hose before starting unit. See "Risk
of Injection" pg. 5. Be sure that all damaged parts are replaced and that
the mechanical problems are corrected prior to operation of the unit. If you
require service, contact Customer Service.
