With the machine resting on a level surface, the correct oil level should reach
the middle of the sight glass on the side of the pump. If the oil level is low, add
sufficient oil to the crankcase. DO NOT OVERFILL.
Crankcase oil [30Wnon-detergent hydraulic (ISO 68) oil]) should be used.
DO NOT USE MACHINE WITH INLET WATER HEATED ABOVE 160°F (71°C).
Crankcase oil should be changed after the first 50 hours of operation and every
500 hours or less thereafter, depending on operating conditions.
GETTING READY
1. For Model GPW-2000-G connect a water hose capable of delivering 3 GPM
(11.4 LPM). For Model GPW-3000-G connect a water hose capable of
delivering 4.8 GPM (18.2 LPM). Consult the Goodway catalog for heavy-duty
water supply hose.
NOTE:
Any restriction in the water supply may cause cavitation and pump
damage. Positive inlet pressure above 25 PSI (1.7 BAR) is required to avoid
cavitation. DO NOT RUN PUMP DRY.
2. Connect the high pressure hose to the quick disconnect on the pump.
3. Insert the dip tube into a container of concentrated soap or chemical, if used.
See "CHEMICAL OR SOAP INJECTION" for a more detailed explanation on
using soap or chemicals.
4. Check crankcase oil level. See instructions under "PUMP LUBRICATION."
5. Read "Before Starting" in the Briggs & Stratton Operating and Maintenance
Instructions provided.
STARTING THE MACHINE
DO NOT ATTEMPT TO START THE ENGINE UNLESS ALL THE
FOLLOWING HAVE BEEN DONE.
