PREVENTATIVE MAINTENANCE

1. Check to see that water pump is properly lubricated.

2. Follow winterizing instructions to prevent freeze dam-

age to pump and coils.

3. Always neutralize and flush detergent from system

after use.

4. If water is known to have high mineral content, use a

water softener in your water system, or de-scale as

needed.

5. Do not allow acidic, caustic or abrasive fluids to be

pumped through system.

6. Always use high grade quality cleaning products.

7. Never run pump dry for extended periods of time.

8. Use clean fuel: kerosene, No. 1 fuel oil, or diesel. Clean

or replace fuel filter every 100 hours of operation. Avoid

water contaminated fuel as it will damage the fuel pump.

9. If machine is operated with smoky or eye burning

exhaust, coils will soot up, not letting water reach

maximum operating temperature.

10. Never allow water to be sprayed on or near the engine

or burner assembly or any electrical component.

11. Periodically delime coils as per instructions.

12. Check to see that engine is properly lubricated.

It is advisable, periodically, to visually inspect the burner.

Check air inlet to make sure it is not clogged or blocked.

Wipe off any oil spills and keep equipment clean and dry.

The flow of combustion and ventilating air to the burner

must not be blocked or obstructed in any manner.

The area around the TUFF washer should be kept clean

and free of combustible materials, gasoline and other

flammable vapors and liquids.

MAINTENANCE AND SERVICE

Unloader Valves:

Unloader valves are preset and tested at the factory be-

fore shipping. Occasional adjustment of the unloader may

be necessary to maintain correct pressure.

Winterizing Procedure:

Damage due to freezing is not covered by warranty. Ad-

here to the following cold weather procedures whenever

the washer must be stored or operated outdoors under

freezing conditions.

During winter months, when temperatures drop below

32°F, protecting your machine against freezing is nec-

essary. Store the machine in a heated room. If this is not

possible then mix a 50/50 solution of anti-freeze and

water in the float tank. Turn the engine on to siphon the

anti-freeze mixture through the machine. If compressed

air is available, an air fitting can be screwed into the float

tank by removing the float tank strainer and fitting. Then

inject the compressed air. Water will be blown out of the

machine when the trigger on the spray gun is opened.

High Limit Hot Water Thermostat:

For safety, each machine is equipped with a temperature

sensitive high limit control switch. In the event that the wa-

ter should exceed its operating temperature, the high limit

control will turn the burner off until the water cools, then it

will automatically reset itself. The thermostat sensor is lo-

cated on the discharge side of the heating coil. The ther-

mostat control dial is located on the control panel.

Pumps:

Use only SAE 30 weight non-detergent oil. Change oil

after first 50 hours of use. Thereafter, change oil every

three months or at 500 hour intervals. Oil level should be

checked through use of dipstick found on top of pump,

or the red dot visible through the oil gauge window. Oil

should be maintained at that level.

Cleaning of Coils:

In alkaline water areas, lime deposits can accumulate

rapidly inside the heating coil. This growth is increased

by the extreme heat build up in the coil. The best preven-

tative for liming conditions is to use high quality cleaning

detergents. In areas where alkaline water is an extreme

problem, periodic use of Deliming Powder (Part

#9-028008) will remove lime and other deposits before

coil becomes plugged. (See Deliming instructions for use

of Deliming Powder.)

Deliming Coils:

Periodic flushing of coils or optional float tank is recommended.

Step 1 Fill a container with 4 gallons of water, then add

1 lb. of deliming powder. Mix thoroughly. Pour

mixture into float tank.

Step 2 Remove wand assembly from spray gun and put

spray gun into float tank. Secure the trigger on

the spray gun into the open position.

Step 3 Turn engine on, allowing solution to be pumped

through coils back into the float tank. The solu-

tion should be allowed to circulate 2-4 hours or

until the color changes.

Step 4 After circulating solution, flush the entire sys-

tem with fresh water. Clean out float tank and

then reinstall wand assembly to spray gun.

Removal of Soot from Heating Coil:

In the heating process, fuel residue in the form of soot

deposits may develop between the heating coil pipes,

and block air flow which will affect burner combustion.

When soot has been detected on visual observation, the

soot on the coil must be washed off after following the

coil removal steps (See Coil Removal on page 11).
