IMPORTANT SAFETY INSTRUCTIONS

PLEASE OBSERVE THE FOLLOWING PRECAUTIONS WHEN USING THIS PRODUCT.

1. Keep this manual with the machine at all times.

2. Read all instructions before using this product.

3. Do not operate without eye protection.

4. To reduce the risk of injury, close supervision is necessary when the product
is used near children.

5. Know how to stop the product and bleed pressures quickly. Be throughly
familiar with the controls.

6. Stay alert— watch what you are doing!

7. Do not operate the product when fatigued or under the influence of alcohol
or drugs.

8. Keep operating area clear of all persons.

9. Do not overreach or stand on unstable support. Keep good footing and
balance at all times.

WARNING: Risk of Injection or Severe Injury – Keep Clear of Nozzle – Do Not
Direct Discharge Stream at Humans or Animals. This Product Is To Be Used Only
By Trained Operators.

CAUTIONS

1. Avoid exposing the machine to freezing temperatures as the pump housing

will crack if water is allowed to freeze in it. If the unit must be exposed to
freezing conditions, run the pump dry for 10 seconds to drain the pump.

3

2. DO NOT RUN THE PUMP DRY FOR MORE THAN 15 SECONDS.

3. When the pump is running without spraying, the bypass valve allows the water to

circulate around the pump. This condition will gradually elevate the temperature
of the water through friction. Frequent or prolonged bypass can result in high
temperature build-up. These high temperatures cause premature failure of the
cups, seals, and packing of the pump. The GPW-2000-G and GPW-3000-G are
equipped with a Thermo Valve which protects the pump against overheating.
When the water temperature reaches 140°F (60°C), the Thermo Valve opens and
dumps the overheated water. Although equipped with a Thermo Valve, RUNNING

THE PUMP FOR MORE THAN 10 MINUTES WITHOUT SPRAYING IS NOT
RECOMMENDED.

4. Do not attempt to change the factory settings of the engine RPM, the bypass

valve pressure setting, or the nozzle orifice size. Doing so may create an un

-

safe condition and shorten the life of the engine and pump.

ABOUT THE ENGINE

The GPW-2000-G is equipped with a Briggs & Stratton 6 HP (4.5 kW) Vanguard
single cylinder engine that drives a three piston oil bath pump. The GPW-3000-G is
equipped with a Briggs & Stratton 14 HP (10.4 kW) Vanguard twin cylinder engine
that drives a three piston oil bath pump. The operator should become familiar with
the information contained in the Briggs & Stratton Operating and Maintenance
Instructions enclosed with this machine. Engine repairs and warranty service are
available directly from your nearest Briggs & Stratton Service Center, which is
listed in the yellow pages under "Engines, Gasoline" or "Gasoline Engines."

NOTE: DO NOT RUN ENGINE WITHOUT AIR FILTER IN PLACE.

PUMP LUBRICATION

IMPORTANT – Please Read Carefully

The GPW-2000-G and the GPW-3000-G are equipped with an oil bath pump.
When shipped, the crankcase is filled with the proper amount of break-in oil.
Due to the possibility of spillage in shipment, the oil level should be checked
prior to the first use of the machine, as well as prior to each use.
