IMPORTANT SAFETY WARNINGS SPRAY PRECAUTIONS: DANGER 2. ALWAYS wear protective goggles when operating the unit to shield the eyes from flying debris and detergents. Other protective equipment such as rubber suits, gloves and respirators are advisable, especially when using cleaning detergents. Use extreme caution when operating near children. ANSIATTI.TIF/D5 1. KEEP AWAY FROM THE SPRAY: a. Because of the high pressure and velocity of the spray, fluids can penetrate the skin, causing serious injury. b.
IMPORTANT SAFETY WARNINGS DETERGENT CLEANING PRECAUTIONS: 1. DO NOT use solvents or highly corrosive detergents or acid type cleaners with this pressure washer. Use only Mi-T-M detergents. 2.

INSTALLATION & PREPARATION ATTIRE: ANSIATTI.TIF/D5 Proper attire is essential to your safety. It is advised to utilize whatever means necessary to protect eyes, ears, and skin. Additional safety attire (such as respiratory mask) may be required when using detergent cleaning agents with this washer. DANGER RISK OF EXPLOSION OR FIRE! DO NOT PLACE UNIT IN AN AREA WHERE FLAMMABLE GAS VAPORS MAY BE PRESENT.
INSTALLATION & PREPARATION NOZZLE REVIEW: Various nozzles may be quick-connected into the end of the wand to change the spray pattern or use the detergent feature. When using Quick Connects (Q.C.), be certain the connection is securely locked. If not, the high pressure water may shoot the nozzle from the wand, causing severe injury or serious damage. To determine spray fan, refer to the actual number stamped on the nozzle. The first two digits indicate the spray fan in degrees, i.e.
INSTALLATION & PREPARATION WATER INLET STRAINER WATER SUPPLY: 1. Select a water supply hose which is a quality grade of garden hose measuring at least 3/4" ID and no longer than 50 feet. 2 Check the water inlet strainer (9) to ensure it is clean and free of any obstructions. Periodic cleaning of the water strainer will help prevent pump problems. As a strainer becomes obstructed, it restricts proper flow of water to the pump.
INSTALLATION & PREPARATION PRE-START INSPECTION PROCEDURES: Before starting the unit, perform the following procedures: 1. Check the oil level in the pump (6) and engine (5). 2. Inspect the water inlet strainer (9). Clean or replace if necessary. See "Water Supply", #2, pg. 12. 3. Check all hose connections to ensure they are securely tightened. See "Water Supply", #5, pg. 12. 4. Inspect for system fuel leaks. If a fuel leak is found, DO NOT START UNIT! See "Fire & Ventilation Precautions", #2 and #4, pg.
OPERATING INSTRUCTIONS PRIMING THE PUMP: 1. It is essential to prime the pump on initial start-up and each time the water supply is disconnected from the unit after initial use. 2. Lay the high pressure hose (16) out to remove any loops. Water flow will constrict the hose, creating tight loops if the hose is not straight. 3. Be certain the nozzle assembly is NOT be connected to the gun assembly at this time. See "Nozzle Connection" page 11. 4.
OPERATING INSTRUCTIONS CLEANING WITH DETERGENTS: 1. Refer to "Detergent Cleaning Precautions" pg. 6 before working with detergents. Be certain to wear protective safety attire as stated on pg. 10. 2. Prepare detergent solution according to label directions. Never pump acids, alkaline, abrasive fluids or solvents through the unit.
