Storage; Between-Use Storage; Prepare Pressure Washer For Freezing Conditions; Prepare Engine For Long Term Storage - NorthStar M15781120F Owner's Manual

When you are finished using the pressure washer, you
must prepare the sprayer for storage and store it in a
proper location.

Between-Use Storage

Perform periodic maintenance as directed in this
manual to keep the pressure washer in safe working
condition.
Choose a storage location that is:
 Clean and dry.
 Away from sources of heat, open flames, sparks,
or pilot lights, even if the pressure washer's
engine fuel tank is empty. Residual fuel fumes
from tank can ignite.
Away from extreme high or low temperatures. Do not
store the pressure washer in freezing conditions unless
it is prepared as directed below for those conditions.
Note:
 If you will be storing the pressure washer in
freezing conditions, follow the instructions for
preparing the sprayer for storage in freezing
conditions.
 If you will not be using the pressure washer
again for 30 days or more, follow the instructions
for preparing the engine for long-term storage.
WARNING: Flammable Materials
 Fuel and its vapors can ignite and cause a
fire. Select a well-ventilated storage area
away from sources of heat, flame, or sparks.

A hot engine can ignite flammable
materials. Always let engine cool at least five
minutes before storing.
Prepare Pressure Washer for Freezing
Conditions
If you will be storing the pressure washer in freezing
temperatures, you must properly prepare the
pressure washer to prevent water from freezing in
the system.
WARNING: Freezing Conditions
Do not allow water to freeze in the pressure
washer, high pressure hose, or spray gun.
Freezing water can cause damage to the
equipment and cause the spray gun to fail in the
open position. A spray gun that has failed in the
open position can whip around and cause
personal injury when the pressure washer is
started.

Storage

1. Drain the water from the high pressure hose and
spray gun by depressing the trigger on the spray
gun until all water drains out.
2. Disconnect the plumbing that connects to the pump
outlet.
3. Obtain the materials you will need:
 12" piece of garden hose or equivalent
 funnel
 approximately 6 oz. of RV antifreeze.
4. Attach the 12" garden hose piece with the funnel to
the pump inlet.
5. Pour RV antifreeze into the funnel, then pull the
recoil a few times until antifreeze comes out of the
pump outlet.

Prepare Engine for Long Term Storage

First prepare the engine for long term storage if you
will not be using the pressure washer for more than
30 days.
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel
system which can cause malfunction of the engine.
1. Prepare fuel system for storage:
 Drain all gasoline from the tank and
carburetor. This is most easily accomplished by
running the pressure washer with the high
pressure hose until the engine stops from lack
of fuel.
