5.  Installation

5.1   From the pump and gearbox (if fitted) remove the ‘Red’ travel plugs,  

replacing them with the yellow-topped dipsticks. Check all oil levels, top  

up if necessary.

5.2  Fill engine with oil and fuel, see engine manufacturers handbook 

for details of oil and fuel types.

5.3  Connect the battery leads. (Electric start models only).

5.4   Connect the suction hose to the Power Washer (fig 3). Ensure the   

connection has no air leaks. Air leaks on the suction hose connection  

will impair the performance of the machine.

5.5   Connect the water return line to its connector and place the other end in  

the water supply container. (Bypass to tank models only)

(Fig 2 item 16 & Fig 4).

5.6   Submerge the opposite end of the suction hose and its suction filter in a  

suitable container containing the water supply (fig 4). Ensure the filter is  

always kept below the water level.

5.7   Connect the high-pressure hose to the power washer (fig 5) and to the  

lance (fig 6). Tighten as appropriate, do not over tighten. 

Ensure that the trigger safety catch is in the 

ON position

 whilst making

these connections.
