THE HI-PRESSURE HOSE AND THE CLEAR CONTROL HOSES MUST BE
SECURELY CONNECTED TO THE POWER UNIT BEFORE THE COMPRESSED
AIR SUPPLY LINE IS ATTACHED.
If the air supply line is connected to the power
unit first, the machine will begin running and damage to the pump may result.
Connect the twin hose as follows:
1. Push the male quick disconnect plug on the hi-pressure hose into the female
quick disconnect on the power unit until the knurled collar clicks into the
locked position.
2. The clear control hoses are attached to the power unit using a brass female
threaded fitting. These fittings thread onto the male threaded valve body
mounted next to the female quick disconnect on the top of the power unit.
The brass fittings must be threaded
AS FAR AS THEY WILL GO
onto the valve body to open the valve allowing for proper operation.
THE BRASS FITTINGS ARE SOMEWHAT FRAGILE SO CARE MUST BE TAKEN
TO AVOID DAMAGING THE FITTINGS.
NOTE:
Either control hose can be connected to either valve.
OPERATION
1. Connect water hose capable of delivering a minimum of 2.5 GPM (13 LPM) to
inlet and turn on faucet. Consult the Goodway Catalog for heavy-duty water
supply hose. DO NOT RUN PUMP DRY.
2. Connect the air supply line to the hose barb fitting using a 1 /
2
" (13mm) ID
or larger air hose. Goodway offers a 1 /
2
" ID x 50' (13mm ID x 15.2m) air
hose – see catalog. Do not use quick disconnects as they restrict air flow.
3. Connect the spray wand and nozzle to spray gun. Motor will start when the
trigger is pulled.
4. After use, disconnect the air coupling and drop a small amount of oil into
the air fitting of the machine. Reconnect the air hose and run the machine
for 2-3 seconds to insure an internal coating of oil inside the air motor to
prevent corrosion. This procedure is important if the machine is to be left
unused for any length of time.
OPERATING INSTRUCTIONS: GPW-2003/GPW-2502
1. Connect a water hose capable of delivering a minimum of 3.2 GPM
