User Maintenance Instructions

All service and repair should be performed by qualifi ed vacuum service representative or electrician. 

Daily Maintenance

1.  Solution tank should be emptied after each use. Flush pumping system with 1 gallon of clean water after 

use.

2.  Removal of nozzle tip, cap, gasket cap, and check valve can expedite system fl ush to allow full water 

fl ow from the pump. See Wand Assembly (pg. 16-17) for details. After system fl ush, de-pressurize sys-
tem by removing power from machine and keeping the spray wand in the on-position until the fl ow has 
stopped. Reassemble spray wand head afterwards as necessary.

3.  Spray jet should be checked for correct spray pattern and cleaned if plugged. Do not clean out spray tip 

with pins or wire, this may cause damage to the jet spray pattern and cause streaking.

4.  Protect equipment from freezing. Severe pumping system damage can occur if allowed to freeze.
5.  Inspect vacuum hoses for tight connections. Check electrical cable for abrasion or cuts in jacket. Cord 

should be replaced if worn or damaged.

Monthly/Bi-Monthly Maintenance

The Solution Pump System should be purged monthly to remove residue build-up. To fl ush system out, use 
1 quart of white vinegar to 1 1/2 gallons of clean hot water, followed by a clear 1 1/2 gallon rinse. Clean 
spray jets if required.

Cord Storage

While not in use storage can be accomplished by winding cord around top of machine. Cord hooks are pro-
vided.
•  Do not use with damaged cord or plug. If appliance is not working as it should, has been dropped, dam-

aged, left outdoors, or dropped into water, return to service center.

•  Do not pull or carry by cord, use cord as handle, close a door on cord, or pull cord around sharp edges or 

corners. Do not run appliance over cord. Keep cord away from heated surfaces.

•  Do not unplug by pulling cord. To unplug, grasp the plug, not the cord.
•  Do not handle plug or appliance with wet hands.

This equipment should be stored indoors and not exposed to rain.
