INSTALLATION & PREPARATION

UNLOADER:

The unloader has been preset at the factory and should only be adjusted by a
trained Mi-T-M Service Representative.

HEAT DUMP VALVE:

To ensure the bypass 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 140° F. This will allow fresh, cool water to enter the system.

PRE-START INSPECTION PROCEDURES:

Before starting the unit, perform the following procedures:
1. Check the oil level in the pump.
2. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply", #2, pg. 11.
3. Check all hose connections to ensure they are securely tightened.
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" warnings,
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" warnings, 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.
