LEVEL OPERATION: During operation, van or trailer must be parked on level
ground not to exceed + or - 10 degrees. Failure to insure proper leveling may
prevent proper internal lubrication of engine, vacuum and/or high pressure com-
ponents.
The machine cannot be run in the IDLE position for cleaning upholstery, carpet or
floor extraction. This will void the warranty.
ACID RINSE AGENTS: The increased demand for “clear water” rinsing results in
the need for special care when using these acid based chemicals in your equip-
ment. The negative side of these products is the corrosive effects the acid can
have on metals, including swivels, pumps, heat exchangers, etc.
HydraMaster’s ClearWater Rinse has been formulated to protect vital compo-
nents. HydraMaster will not warranty parts that have been damaged from using
unprotected acid products that have obviously caused failures.
HARD WATER PROTECTION: Failure to take appropriate measures to prevent
scale build up can result in system failure and loss of warranty on affected parts.
Test the water in your immediate and surrounding areas with hard water test
strips. Assume all water obtained from wells is hard. If you are operating in a
“Hard Water Area” (3.5 grains or more per gallon), use a water softening system.
FREEZE PROTECTION: There is often little warning before a cold spell. There-
fore, not protecting this equipment from freezing will result in costly downtime.
Placing an electric heater in the truck or parking the truck indoors will help to
insure against freezing, but should not be the primary method of freeze protec-
tion.
