SPRAY PRECAUTIONS

DANGER : RISK OF INJECTION OR SEVERE CUTTING INJURY!
KEEP CLEAR OF NOZZLE! DO NOT DIRECT DISCHARGE STREAM AT PERSONS OR PETS! ONLY TRAINED OPERATORS SHOULD USE THIS PRODUCT. WHEN OPERATING THIS UNIT, BASIC PRECAUTIONS SHOULD ALWAYS BE OBSERVED
INCLUDING THE FOLLOWING:

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. Never point the gun at yourself or anyone else. Never put your hand, fingers or body directly over the spray nozzle. Always keep operating area clear of all persons. Use extreme caution when operating near children.
c. If an accident does occur and the spray appears to have penetrated the skin, SEEK EMERGENCY MEDICAL CARE. DO NOT TREAT AS A SIMPLE CUT. If you are using cleaning agents, be prepared to tell a physician exactly what kind.
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.
Stay alert-watch what you are doing. Do not operate the unit when fatigued or under the influence of alcohol or drugs.
NEVER squeeze the trigger unless securely braced. The thrust from the water traveling through the nozzle may be powerful enough to cause the operator to lose balance if unprepared. DO NOT overreach or stand on unstable support. Wet surfaces can be slippery, wear protective foot gear and keep good footing and balance at all times. NEVER trigger the gun while on a ladder or roof.
Caution should be used when directing spray toward fragile materials such as glass. Shattering could result in serious injury.
ALWAYS hold on firmly to the gun/wand assembly when starting and operating the unit. Failure to do so can cause the wand to fall and whip dangerously. NEVER operate the gun with the trigger wired in the open position. To prevent accidental discharge, the trigger gun should be securely locked when not in use.
DO NOT direct spray on or into electrical installations of any kind! This includes electrical outlets, light bulbs, fuse boxes, transformers, etc. Severe electrical shock may occur.
Even after you shut off the unit, there is high pressure water left in the pump, hose and gun until you release it by triggering the gun. Before removing the spray nozzle or servicing the unit, ALWAYS shut off the unit and trigger the gun to release trapped pressure.

DETERGENT CLEANING PRECAUTIONS

DO NOT use solvents or highly corrosive detergents or acid type cleaners with this pressure washer. Use only Mi-T-M detergents.
KNOW YOUR DETERGENTS! Be prepared to tell a physician exactly what you are using in the event of an emergency. Read the Material Safety Data Sheet (MSDS) provided with your detergent and all detergent labels. Follow all appropriate instructions regarding preparation use, safety and transportation. Keep ALL detergents out of the reach of children.
DO NOT use this pressure washer to dispense hazardous detergents.
DO NOT alter the detergent injection feature in any manner not prescribed in this manual. Use only genuine Mi-T-M replacement parts for necessary repairs.

MISCELLANEOUS SAFETY PRECAUTIONS

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.; 15=15°, 25=25°, 65=detergent/low pressure.

The 15° nozzle (YELLOW): This is a chiseling nozzle. The spray should be directed at a 45° angle to the surface and used like a scraper to remove paint, grease and dirt. Uses: Surface preparation (removing mildew stains and paint chips).
The 25° nozzle (GREEN): This is a flushing nozzle. This pattern is best suited for flushing dirt, mud, and grime. Uses: Wet sweeping leaves from walks, curbs and driveways, cleaning stable floors, washing swimming pool bottoms, degreasing engines.
The 65° nozzle (BLACK): This is a low pressure detergent application nozzle. This broad spray pattern distributes solution over vast areas under low pressure. Uses: Detergent application, misting or rinsing.

WARNING RISK OF INJECTION CAUSING SEVERE INJURY!
NEVER LOOK DIRECTLY AT THE NOZZLE ORIFICE UNLESS IT IS DISCONNECTED FROM THE GUN/WAND ASSEMBLY!

NOZZLE CONNECTION:

Be certain the trigger gun is locked in the “OFF” position. See WARNING, right.
The nozzle assembly should be disconnected from the gun/wand assembly at this time by retracting the locking ring on the quick-connect fitting to remove the nozzle.

UNLOADE R:
FACTORY PRESET:
The unloader valve on your machine is factory preset and should only be adjusted by a trained Mi-T-M Representative. DO NOT adjust the pressure on your own!

WATER SUPPLY:

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.
Check the water inlet strainer 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. This can result in cavitations which will cause premature failure of pump packings.
a. Using a screw driver, remove the screen from the water inlet.
b. Clean or replace with Mi-T-M® #19-0001 if necessary.
Connect the hoses.
a. Connect one end of the water supply hose to the water inlet of the unit.
b. Connect the other end of the hose to your pressurized water supply.
NOTE : Do not use a non-pressurized water supply (i.e. from a pond or well) with this unit.
c. Connect the high pressure discharge hose to the water outlet of the unit.
d. Securely connect the other end of the hose to the gun assembly. (A wrench may be required on some models.)
e. Connect the wand assembly to the gun/hose assembly.
Follow the incoming water requirements listed below:
a. Water pressure must be a minimum of 25 pounds per square inch (PSI) and a maximum of 125 PSI. (A typical outdoor faucet will generally supply this PSI if turned completely “ON”.)
b. Incoming GPM must be approximately one gallon more than the outgoing GPM stated on the pressure washer nameplate. (You can check GPM by timing how long it takes to fill a 5 gallon container.)
c. Incoming water temperature must not exceed 125°F. Excessive pump damage may result if the water temperature exceeds this acceptable level.
Never allow the unit to operate without the incoming water line attached and the water supply completely turned on.

INSTALLING HANDLE:
TOOLS NEEDED; ½” SOCKET, RATCHET

Slide handle over the tubes on frame. Hold in place while inserting carriage bolts from the inside of the frame thru the tubes and thru the handle.
While still holding handle to prevent it from falling, tighten large knobs onto carriage bolts until knobs on both sides are completely tight.
Thread (1) locknut on the end of the carriage bolt and tighten with ½” socket, only until the threads of the carriage bolt are flush or slightly past the end of the lock nut. (see picture to the left)
Repeat step three on opposite side

THERMAL RELIEF 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 gun closed) for more than three minutes.
A “thermal relief 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:

Check the oil level in the pump and engine.
Inspect the water inlet strainer. Clean or replace if necessary. See “Water Supply”.
Check all hose connections to ensure they are securely tightened. See “Water Supply”.
Inspect for system fuel leaks. If a fuel leak is found, DO NOT START UNIT! See “Fire & Ventilation Precautions”. 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.
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 “Miscellaneous Safety Precautions”. 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.

OPERATING INSTRUCTIONS

CAUTION RISK OF UNIT DAMAGE.
BE CERTAIN THE NOZZLE IS NOT CONNECTED TO THE UNIT WHILE PRIMING THE PUMP.
PRIMING ALLOWS MINERAL DEPOSITS TO BE RELEASED FROM THE SYSTEM WHICH WOULD OBSTRUCT OR DAMAGE THE NOZZLE ASSEMBLY RESULTING IN COSTLY REPAIRS.

PRIMING THE PUMP:

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.
Lay the high pressure hose out to remove any loops. Water flow will constrict the hose, creating tight loops if the hose is not straight.
NOTE : The nozzle assembly should NOT be connected to the gun assembly at this time. See “Nozzle Connection” .
With the trigger gun locked in the “OFF” position, turn the water supply completely on. Pointing the gun in a safe direction, unlock the trigger gun and squeeze the trigger.
Low pressure water will begin flowing from the hose/gun assembly. This allows the unit to prime and purge any air from the system. The unit is primed when water flow is uninterrupted by air.
Once the unit is primed, release the trigger and lock the gun in the “OFF” position. Securely connect the nozzle assy. (See “Nozzle Connection”)

DANGER RISK OF INJECTION CAUSING SEVERE INJURY!

KEEP CLEAR OF NOZZLE! NEVER PLACE HAND OR FINGERS IN FRONT OF NOZZLE!
DO NOT DIRECT DISCHARGE STREAM AT PEOPLE OR PETS!
BE CERTAIN THE NOZZLE IS SECURELY CONNECTED TO THE WAND TO PREVENT ACCIDENTAL DISCHARGE!

CAUTION RISK OF DAMAGE.
DO NOT ALLOW SPRAY PATTERN TO REMAIN ON A FIXED AREA FOR AN EXTENDED PERIOD OF TIME. POSSIBLE DAMAGE MAY OCCUR TO THE AREA.

START-UP

Refer to the “Safety Precautions” before starting the unit.
Locate the Safety Decals on your unit and heed their warnings.
With the gun locked in the “OFF” position, point the trigger gun away from yourself or anyone else. Ensure the water supply is completely turned on.
Disengage the safety lock-off on the gun and squeeze the trigger. Low pressure water will begin flowing from the nozzle.
BE CERTAIN the trigger gun remains in an open position while starting the engine. Brace yourself as the gun will kickback from the high pressure created by the pump once the engine has started.
Steady the unit during engine start-up. (Refer to the engine manual accompanying this pressure washer for the correct procedures needed to start the engine.)
Once the engine has started, perform the following procedures with the gun open:
a. Inspect for system oil leaks and fuel leaks. If a fuel leak is found, TURN UNIT OFF IMMEDIATELY! See “Fire & Ventilation Precautions”. 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.
b. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak is found, DO NOT TOUCH HOSE AT LEAK!!! TURN UNIT OFF IMMEDIATELY! Replace hose before restarting the unit. See “Miscellaneous Safety Precautions”. 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.
Trigger the gun several times. Be certain to LOCK the trigger gun in the “OFF” position whenever changing the quick connect nozzles. NEVER look directly into the nozzle! High pressure water creates a risk of severe injury!
Do not allow unit to operate in bypass mode (with trigger closed) for more than three minutes without triggering the gun. Failure to follow this simple rule can cause premature failure of pump packing seals, resulting in costly pump repair.
Because your pressure washer delivers a high pressure spray and a variety of spray patterns, there are many cleaning jobs that can be done without the use of detergents. If a cleaning agent is required, see “Cleaning With Detergents” for the correct procedures.

OPERATING INSTRUCTIONS

CLEANING WITH DETERGENTS:

Refer to “Detergent Cleaning Precautions” pg. 6. Be certain to wear protective safety attire as stated on pg. 10.
Prepare detergent solution according to label directions. Never pump acids, akalines abrasive fluids or solvents thru the unit.
Pour prepared detergent solution into chemical tank mounted on the unit.
With the trigger gun locked in the “OFF” position, remove high pressure nozzle and replace with low pressure detergent nozzle at the end of the wand away from the gun.
NOTE : This injection system is designed to apply detergents under low pressure only. It will not allow detergent solutions to be introduced into the system unless the low pressure nozzle is being used.
To apply solution, unlock the trigger gun and squeeze the trigger. In a few moments a detergent/water mixture will exit the low pressure nozzle. Start spraying the lower portion of the surface being cleaned and move up, using long overlapping strokes. Applying from the bottom up helps avoid streaking. Allow to soak briefly. (Avoid working on hot surfaces or in direct sunlight to minimize the chances of the detergent drying, which may result in damaging painted surfaces.) Be certain to rinse a small section at a time.
To rinse; lock the trigger gun in the “OFF” position, replace the low pressure detergent nozzle at the end of the wand with high pressure nozzle. Unlock the trigger gun and spray. It will take about 30 seconds to purge all detergent from the line. For best rinsing results, start at the top and work down.
Siphon a gallon of water through the low pressure detergent injection system after each use. This prevents the possibility of corrosion or detergent residue causing mechanical problems during the next use

SHUTDOWN:

Turn engine “OFF” as directed in the engine manual.
Turn the water supply “OFF”.
Pointing the gun in a safe direction, trigger gun momentarily to relieve any trapped pressure.
Once pressure is relieved, disconnect the nozzle assembly.
Disconnect and drain gun, wand and hoses.
Wipe unit clean and store with gun, wand and hoses in a safe, nonfreezing area.

STORAGE & MAINTENANCE

ENGINE : The engine instructions that accompany your unit detail specific procedures for maintenance of the engine. Following the engine manufacturer’s recommendations will extend engine work life.
PUMP: The pump oil must be changed after the first 25 hours of operation. Once the initial oil change has been completed, it is recommended the oil be changed every 3 months or 250 hour intervals. If oil appears dirty or milky, changes may be required at a greater frequency. Add pump oil and fill only to the center of the sight glass (Refer to the parts listing for the correct pump oil). DO NOT OVERFILL!
NOZZLES : Water flow through the spray nozzle will erode the orifice, making it larger, resulting in a pressure loss. Nozzles should be replaced whenever pressure is less than 85% of the maximum. The frequency of replacement will depend upon such variables as mineral content in the water and number of hours the nozzle is used.
QUICK COUPLERS: There is an o-ring seal inside the female quick coupler. This o-ring will deteriorate or, if the unit is allowed to pump without the high pressure hose or nozzle attached, the o-ring may be blown out occasionally. Simply insert a replacement o-ring to correct the leak. (Additional o-rings can be purchased from your dealer.)

WINTERIZING:
For storage and transportation purposes in subfreezing ambient temperatures, it will be necessary to winterize this unit. This unit must be protected to the lowest incurred temperature for the following reasons:

If any part of the pumping system becomes frozen; excessive pressure may build up in the unit which could cause the unit to burst resulting in possible serious injury to the operator or bystanders.
The pumping system in this unit may be permanently damaged if frozen.

FREEZE DAMAGE IS NOT COVERED BY WARRANTY.
