HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY
Never point or aim the gun/wand at yourself or anyone else. Never put your hand, fingers or body directly in front of the spray nozzle.
A. KNOW YOUR PRESSURE WASHING EQUIPMENT
1. READ YOUR OWNERS MANAUL CAREFULLY. Do not operate your power washer until you completely understand and can follow all operating instructions, precautions and safety rules. 2. Restrict the use of your power washer to users who have read, understand and can follow all operating instructions, precautions and safety rules.
B. PLAN AHEAD
1. Always wear ear protection to cut noise and eye protection and / or face shield to prevent debris from flying or ricocheting into eyes and face which could result in serous injury. 2. Dress safely in long pants and wear boots or shoes. Other protective equipment is advisable when using chemicals, cleaning detergents or other corrosive or abrasive substances. 3. Do not operate pressure washing equipment if you have consumed alcohol or taken medication. 4. Keep pets, children and bystanders a safe distance away from your work area. A minimum of 50 feet is recommended. 5. Do not spray directly at glass or fragile objects. 6. CAUTION after turning off your pressure washer and water supply, there is still high pressure water trapped in the system. You must release the pressure by triggering the gun after the engine has completely stopped. 7. Know what chemicals you are using and read precautions.


	PRECAUTIONS FOR GASOLINE ENGINES
1. Follow all safety precautions, operating procedures and maintenance listed in your engine operator’s manual which came with the pressure cleaner. This manual may be attained from your local small engine repair center. 2. DO NOT fill the engine with gasoline when the engine is running, hot or near an open flame. DO NOT SMOKE. 3. Do Not run power washers in an enclosed area. Exhaust fumes contain poisonous carbon monoxide gas. Breathing exhaust gases can cause serious illness or death. 4. Do Not touch or come in contact with hot mufflers, cylinders, cooling fins or hot exhaust gases as this may result in severe burns. 5. Never tamper with governor spring, governor links or other components which may increase the speed (RPM) of the engine. 6. Do Not operate pressure cleaners in the presence of flammable vapors or gases. When servicing pressure cleaning equipment, be sure to properly dispose of any flammable materials. 7. Do Not make adjustments to your equipment without first removing the spark plug. 8. When transporting pressure cleaners, the fuel shut-off valves must be in the closed position, to prevent fuel from spilling out.


	MISCELLANEOUS SAFETY PRECAUTIONS
1. Check all high pressure hose and fittings periodically for cuts or wear. Immediately replace all suspect components to prevent injury. Do not place high pressure hose on the engine muffler or drag across abrasive surfaces. 2. Inspect pressure cleaner for oil, fuel and/or water leaks. 3. Operate unit on level surface only. Otherwise fuel may spill on engine and/or pump. Lubrication may be insufficient if unit is not level. 4. Never start power washers without adequate water supply. 5. Never leave a pressurized unit unattended. Always shut off the unit and relieve trapped pressure before leaving. 6. Do Not run the unit for longer that 3 minutes with spray gun in the closed position. 7. Clean up spilled soap, fuel or oil immediately to avoid falls. 8. Keep clutter out of work area to avoid falls. 9. Never squeeze the spray gun trigger unless you are securely braced. The force of water through the nozzle is powerful enough to cause you to lose your balance and fall. 10. Never attempt to use power washers on or near any electrical outlets, fuse boxes, transformers, high voltage wires, etc. Severe electrical shock or death may occur. 11. Only use genuine pressure cleaning equipment parts for any and all repairs of your pressure cleaner. Failure to do so may result in injury or cause hazardous operating conditions to exist.

1. Follow recommended service instructions in owner manual for engine. 2. Change oil in pump after the first 20 working hours (break in period) and then every 150 hours of operation. The oil drain bolt is located on the bottom side of the pump. When refilling or adding oil to your pump, the pressure cleaner should be on level ground. Most pressure cleaners have a site glass located on the side of pump, the oil level must be in the center of the site glass. See pump manufacturer specification sheet for proper lubrication. Click HERE to order pump oil or call CMC at 1(800) 544-2111, Mon/Sat 8-9 EST. 3. Prevent pump from freezing during freezing conditions. Flush pump with 1 to 1 mixture of automobile anti-freeze and water. This will also act as a lubricant.
	PRESSURE WASHER CARE

1. Avoid extending hoses across high traffic areas while using power washers, and never leave the hose where it may be ran over by vehicles of any type. 2. Never pull on the hose to move the pressure washer. 3. Never pull your pressure hose around a tight corner or force it into a small loop. The wire braid hose has a minimum bend radius of 5”, and should not be forced into any small bend. 4. Wrap up the pressure washer hose when finished cleaning and store it on a hose hook or other safe location. 5. Check oil levels (pump & engine) at every fueling to prevent low oil damage. 6. Inspect inlet water filter for cleanliness and damage. If soiled or dirty, rinse with fresh water. If damaged, replace with new filter. Click HERE to order inlet filter or call CMC at 1(800) 544-2111, Mon/Sat 8-9 EST. 7. When lifting or transporting power washers, secure and lift with only appropriate lifting handles.

GENERAL INSTRUCTIONS & PREPARATION OF PRESSURE WASHING EQUIPMENT
NOZZLE SELECTION GUIDE Spray nozzle can be identified by the nozzle “number”, a four or five digit number that is stamped on the nozzle, which indicates the spray angle and orifice size. In all cases the first two digits of the nozzle number indicate the spray angle in degrees. EXAMPLE: 00 is 0 degree, 15 is 15 degree, 25 is 25 degree and 40 is 40 degree. The last two digits of the nozzle number indicate the orifice size, a standard industry designation. EXAMPLE: 06 is a 6.0 orifice, 55 is a 5.5 orifice. These numbers correspond to the actual dimensions, giving the size of the orifice. They do not however directly indicate gallons per minute, flow rates or inches in diameter of the orifice. Some power washers come with an adjustable nozzle which is fixed to the end of the wand. The fan spray may be adjusted by turning the nozzle, chemical may also be applied by pulling out word on the nozzle. STANDARD SPRAY NOZZLE APPLICATIONS Caution: The spray force from these nozzles can cause injuries if pointed directly at yourself or others. Before observing directly always disconnect from spray wand.

	Siphons detergent or chemical from it’s own source and induces into the high pressure side, downstream from pump. Used to dilute and apply detergents or chemicals to any surface. The adjustable chemical Injector has an easy dial to control detergent/chemical flow from 0 to 10 or 20%. Non-Adjustable Injectors are fixed at10 or 20%.
	CHEMICAL INJECTOR
The flow rate of chemical injectors will vary, depending on the brand. Flush chemical injector after each use by siphoning one gallon of clean water. Click HERE to order your chemical injector or call CMC at 1(800) 544-2111, Mon/Sat 8-9 EST.

	INLET WATER FILTER
An inexpensive way to protect your pressure cleaner. Positioned at the inlet water supply connection of your pressure cleaner for easy access. The filter should be checked prior to each use by unscrewing the cap and removing the filter screen. If clogged, rinse screen with fresh water, be careful not to kink or damage the screen. Replace filter and tighten cap, be sure not to over tighten, for gasket may kink and cause a leak. If screen, cap or filter housing is damaged the inlet filter assembly must be replaced.

THERMO RELIEF VALVE
The thermo relief valve is designed to open and release hot water that exceeds 145 degrees when system is in bypass-mode. The releasing of hot water allows cold water to enter system and keeps the pump operating within temperature limits. Temperature that exceeds 145 degrees will cause premature packing seal failure. If this occurs and the pump overheats, the valves should be replaced. Click HERE to inquire about your thermal relief valve, or call CMC at 1(800) 544-2111 Mon/Sat 8-9 EST.

Pressure cleaners are installed with one of two types of unloaders: The Trapped Pressure Unloader or the Flow Actuated Unloader. After the water exits the pump, its flow of direction must be controlled with the unloader or regulating valve. A positive displacement pump is always delivering a certain volume of water whether the spray gun is open or closed, therefore a device is needed to control the direction of flow, either to the open spray gun or redirecting the flow back to the inlet side of the pump when the spray gun is closed. Without an unloader valve, dangerously high pressure will be produced when the spray gun is closed because the water being forced out of the pump has no place to go. The unloader is used as a safety device to guard against failure of component parts, and the development of dangerously high pressures.Click HERE to order your unloader valve, or call CMC at 1(800) 544-2111 Mon/Sat 8-9 EST.
	THE UNLOADER VALVE

The quick connects supplied with your pressure cleaner are for the convenience of attaching and removing hoses and accessories. To operate the quick connect, slide back the collar on the socket half and insert or remove the quick coupler plug. Make sure the plug is firmly seated in the socket so that the safety collar is locked In place. There is an O-ring seal inside the female quick connect which will deteriorate or be blown out occasionally. This may occur if the unit is allowed to pump without the hose or nozzle attached. Simply insert a replacement O-ring to correct the leak. Some power washers are equipped with 22mm couplers, these couplers are the screw on type, very similar to garden hose connections. Be sure the to tighten securely. Click HERE to order your quick couplers, or call CMC at 1(800) 544-2111 Mon/Sat 8-9 EST.
	QUICK CONNECTS / QUICK COUPLERS

ANTI-FREEZE (WINTERIZING)
To protect pressure cleaners from severe damage which will result from water freezing inside the pump, heating coil and other components, follow this procedure whenever the pressure cleaners must be exposed to freezing temperatures. If compressed air is available, first blow the system using an air valve on the pump outlet. 1. Obtain a 5-gallon container of permanent anti-freeze. 2. Remove nozzle from wand and lay out the hose and wand flat on the floor. 3. A. Float tank- remove feeder supply hose, drain float tank. Fill tank with anti- freeze, hold open the trigger gun, if equipped. Turn on pump. B. No float tank- remove water supply hose, place a suction hose from pump drawing anti-freeze, hold open the trigger gun, if equipped. Turn on pump drawing anti-freeze into the system. 4. When anti-freeze appears at the end of the gun, turn off pump. 5. When preparing to operate your pressure cleaner the next time, reconnect water supply and have anti-freeze container handy. Turn the pump on, direct flow of anti- freeze into its container, taking care not to dilute it with the water following through the unit. Anti-freeze, if kept relatively undiluted, can be used again and again.
