installation & preparation
unloader:
If the unloader on your machine is equipped with an adjustment knob, you
can adjust the pressure. Should less pressure be required, simply turn the
adjustment knob counterclockwise. To set back to maximum, turn adjustment
knob completely clockwise. DO NOT OVERTIGHTEN!
If the unloader does not have an adjustment knob, DO NOT adjust the pressure
on your own! The pressure has been preset at the factory and should only be
adjusted by a trained Mi-T-M Customer Service Representative.
pre-start inspection procedures:
Before starting the unit, perform the following procedures:
. Check the oil level in the pump.
2. Inspect the inlet water strainer. Clean or replace if necessary. See "Water
Supply", #2, pg. 11.
. Check all hose connections to ensure they are securely tightened. See
"Water Supply", #3, pg. 11.
4. Inspect for system water leaks and oil leaks. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected prior to
operation of the unit. If service is needed, contact an Authorized Service
Center.
5. Inspect high pressure hose for kinking, cuts or leaks. If a cut or leak is found,
DO NOT USE HOSE! Replace hose before starting unit. See "Miscellaneous
Safety Precautions" #6, pg. 6. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of the
unit. If you need service, contact an Authorized Service Center.
6. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR USE
ELECTRICAL CORD! Replace cord before starting the unit.
tHermal relief ValVe:
To ensure that 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 gun closed) for more than three minutes.
A "Thermal Relief Valve" has been added to this unit to protect the pump. It
will 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.
power cord connection:
1. Make certain the motor switch is in the "OFF" position.
2. Ensure electrical supply matches that shown on identification plate located
on unit base plate.
3. If your unit is equipped with a GFCI, test the GFCI according to the instructions
on the GFCI. Do not use if the test fails!
4. Ensure the area between the pressure washer cord and the outlet is kept
dry.
5. Insert the male plug into a properly grounded AC outlet.
