How to Clean With a Coleman Powermate 1300 Power Washer

Steven Douglas

Coleman Powermate electric pressure washers have been used for years to clean home exteriors, boat and marine components, strip paint from painted surfaces and remove graffiti, dirt and other debris from concrete surfaces. The Coleman Powermate 1300 offers a portable, yet powerful and efficient way to clean these types of surfaces without a lengthy set-up procedure. All electric models, such as the 1300 series, have been developed to allow for a low-space storage solution, as well as provide an efficient way to power wash without the complexity of a gasoline-powered water pump, nor the noise they produce. Learning how to clean with a Coleman Powermate 1300 may be accomplished by following a few basic guidelines.

Step 1

Roll the power washer (unit) near the item to be cleaned. Connect a garden hose to an outdoor hose bib, nearest to that location. Since an electrical extension cord (if used) may not exceed 50 feet, be sure the area where you will be using the power washer has water and electricity nearby.

Step 2

Connect the garden hose to the unit by attaching the included nipple hose adapter to the water inlet fitting on the unit (water inlet fitting is located on the lower front of unit). It is a screw on connection, so twist it clockwise until tight.

Step 3

Attach the included quick connect hose fitting to the garden hose by twisting it on in the clockwise direction. Snap the quick connect fitting onto the nipple adapter on the unit to successfully connect the garden hose to the unit.

Step 4

Connect the high pressure hose and spray wand assembly to the unit by screwing the hose connector onto the water output port located on the bottom front of the unit. Unravel the hose so that it has no kinks in it, twist the hose if necessary so that it is not still coiled tightly after being in storage.

Step 5

Plug the power cord from the unit into a grounded 120 volt electrical outlet. Press the "reset" button, located on the face of the power cord plug, before turning the machine on. This safety step must be competed each time the unit is plugged into an outlet.

Step 6

Turn on the hose bib to the full "open" position to generate the maximum amount of water available to the unit. Hold the spray wand firmly with both hands and squeeze the trigger located on the inside of the handle. Turn the power switch located at the top of the unit to the "on" position. Release the trigger. The unit is now properly set up to use; it will start and stop each time the trigger is depressed and released.

Step 7

Adjust the nozzle of the spray wand while depressing the trigger. Twist the nozzle (located at the end of the spray wand) clockwise to utilize a wide "fan" pattern of water output. Twist the nozzle counterclockwise to utilize a narrow "fan" pattern, which resembles a pencil stream of water. Twisting the nozzle incrementally will vary the spray pattern from approximately 0 degrees (narrow high impact stream) to a 60 degrees (wide fan spray with lower impact stream). Twist the nozzle to the desired spray range. Aim in a safe direction to test the spray pattern.

Step 8

Determine the proper spraying distance. Depending on your spray pattern and the item you are washing, your ideal distance from the target will vary. Normally, a distance between 3 and 4 feet is best for pressure washing without damaging the surface. Closer distance is required to remove stubborn concrete stains.

Step 9

Wash the desired area from top to bottom on a vertical surface. Aim at the top of the desired area, with the wand pointed away from the surface. Squeeze the trigger to begin washing, then swing the nozzle to bear of the surface to be cleaned and adjust your wand distance as desired. Remember that gravity plays a part when pressure washing. Work from the top downward on vertical surfaces in order for all dirt and soap residue to flow downward, leaving a clean surface above.

Step 10

Wash the desired horizontal area from farthest away from you to nearest to you. This is so that you don't walk on clean areas, or drag the water hose and electric cord through already cleaned areas; the hoses often have dirt and debris sticking to them since they are wet.

Step 11

Turn off the washer by releasing the trigger, then moving the on/off switch to the "off" position. Unplug the unit. Turn off the water at the hose bib. Squeeze the trigger several times to expel water trapped in the hose. Unscrew the hose from the unit. Store the unit in a clean, dry location.
