INSTALLATION
•
Inspect shipment for damages during transit and unpack
•
Top engine fuel tank up with clean, fresh, Petrol
WARNING – PLEASE READ SAFETY INSTRUCTIONS FIRST!
•
For portable machines: Connection supply hose to water supply:
-
Important: Use hose with minimum 20 mm inside diameter
-
Required pressurised water supply (not gravity) with minimum of 10 PSI and ~20%
more flow that pump flow rate (litres per minute)
-
Turn on the water supply (open tap fully). Water will fill the break tank if fitted
For Skid-mounted units and Trailer-mounted units – ensure tank has enough water and the
water level is at least above the low level float switch otherwise the engine won’t start
•
Unroll the hose fully ensuring there are no kinks in it
•
Trigger gun to expel any air in the system
LAST CHECKS & START:
•
Check all hoses are connected and check for damage or water leaks
•
Check oil level in the pump. The oil sight glass should be HALF full – not more! If oil need
to be topped up, use SAE10W40 or SAE 15W40 or SAE30 and top up at the Slave Oil
Tank if fitted, otherwise on the pump itself.
•
Ensure water supply tap (on portable machines) or tank ball valves are wide open
For the HONDA GX200 – 6.5 hp & GX390 – 13 hp engines
To Start:
•
Ensure that the main RED ON/OFF switch is switched to OFF.
•
Ensure the Choke is ON (Moved fully to the left) when engine is cold
•
Ensure Fuel is OPEN (Fuel lever moved all the way to the right)
•
Now take the recoil start handle attached to the recoil rope and give it 2 slow pulls to prime
engine.
•
Now switch the main RED ON/OFF switch to ON and give the recoil handle firmly and fast
fully extended pull. The engine should fire up.
•
As soon as the engine fires up, turn Choke to the OFF position by pushing the choke lever
all the way to the left.
•
NOTE: engine revs is locked. Do not attempt to unlock or change this. It will void your
warranty! Engine is set to run at top torque curve – set up to optimal revs for the pressure
and flow.
•
The engine is now running, pump is pumping and water is running in by-pass.
•
Pull the trigger on the gun by pointing the lance in a safe direction.
•
When the trigger is released, the pump is still pumping and water is in by-pass.
To Shut down:
•
Flick the main red ON/OFF switch back to the OFF position
•
Turn the fuel supply off by pushing the fuel supply lever all the way to the LEFT.
•
Turn water supply off and disconnect (Portable units)
•
Squeeze trigger a few times to ensure no pressure is stored in the hose.
•
Roll out the hose and then roll it up avoiding any kinks
For the HONDA GX630 – 20 hp engine:
To Start:
•
Ensure that the fuel tap on the bottom of the stainless steel fuel tank is open and that the
fuel tank is full.
