STOPPING THE ENGINE
STOPPING IN AN EMERGENCY
1. To stop the engine immediately, place the engine ON/OFF switch in the "OFF" position.
STOPPING IN NORMAL USE
1. Place the throttle control in the "SLOW" position.
2. Place the engine ON/OFF switch or key switch in the "OFF" position.
3. Place the fuel tap in the "OFF" position.
ENVIRONMENTAL CONSIDERATIONS
• Altitude: If the engine is being used in altitudes at or above 1500m (approximately 5000'), adjustments to the
carburettor may be required. This is because there is less oxygen in the air as altitude increases, which effectively
"enriches" the ratio of fuel to air going into the engine and the higher the altitude, the richer the fuel mixture
becomes. If the engine is being permanently operated at high altitude, it is recommended to have an authorized
service centre make the necessary carburettor adjustments. If the engine is used occasionally at altitude (not
extreme altitudes), no adjustments should be required, however, a slight decrease in engine performance can
be expected.
• Temperature: If the engine is being used in extremely cold or hot environments; for example, desert or snow
conditions, the type of engine oil may need to be changed to suit environmental temperatures. Oil thickens as
the temperature decreases and thins as temperature increases, which means that if the engine oil is not suited to
the temperature its ability to properly lubricate the engine may be affected. Use the following chart to determine
the correct engine oil:
USE
Note that once the engine is running, the pumping action of the machine is activated. When the engine is idling
(slower continuous running speed), the output water pressure is minimal. As the engine speed increases (use the
engine throttle control), the water pressure increases. Please note the following recommendations:
• Run the motor at a sufficient speed to provide the desired outlet pressure.
• Use the correct nozzle for the job you want to do. Nozzles that concentrate the water jet in a small area can
puncture and damage materials on some surfaces.
• Before starting work, pressure clean a small test area to ensure that the surface will not be damaged and the
machine will clean the surface properly.
• Completely unroll the high pressure hose(s) before using the machine.
• Use a sweep and overlap motion to help ensure effective cleaning and full surface coverage.
• When cleaning with detergents, always rinse the residue afterwards.
