Safety precautions Gasoline Engine Safety Setting up on uneven surfaces The front side of the unit must point downwards to prevent sliding away. Always place sprayer outside of structure in fresh air. Keep all solvents away from engine exhaust. Never fill fuel tank with a running or hot engine. Hot surface can ignite spilled fuel. Always attach ground wire from pump to a grounded object.

Description of unit Operating Temperature This equipment will operate correctly in its intended ambient, at a minimum between +10°C and +40°C. Relative Humidity The equipment will operate correctly within an environment at 50% RH, +40°C. Higher RH may be allowed at lower temperatures. Measures shall be taken by the Purchaser to avoid the harmful effects of occasional condensation. Altitude This equipment will operate correctly up to 2100 m above mean sea level. Transportation and Storage This equipment will withstand, or has been protected against, transportation and storage temperatures of -25°C to +55°C and for short periods up to +70°C. It has been packaged to prevent damage from the effects of normal humidity, vibration and shock.
Starting operation Starting operation 2. Operating position I (fig. 10) Swiveling the material feed pump to a vertical position allows Changing the material feed pump position the material feed pump to be immersed in the coating material container. Be careful, as the moving parts of the swivel mechanism can crush fingers and feet.
Starting operation High-pressure hose, spray gun and separating Gasoline engine (gas units only) 1. Fill in the supplied engine oil. The gasoline engine is transported without engine oil. 1. Screw the high-pressure hose (fig. 12, item 1) onto the hose connection (2). The oil-level sensor prevents the engine from being started when the oil level is too low. 2. Screw HC 950-SSP • HC 970 and HC 970-SSP double socket (3) into the high-pressure hose.
Taking the unit into operation with coating Never pull on the high-pressure hose to move the device. material Make sure that the high-pressure hose cannot twist. This can be avoided by using a Wagner spray gun with a swivel joint and a hose system. If the unit is located on a non-conductive surface (e.g. a wood floor), earth the unit with an earthing cable.
Cleaning the unit (shutting down) Cleaning the unit (shutting down) Cleaning the unit from the outside A clean state is the best method of ensuring operation without problems. After you have finished spraying, clean the unit. Under no Gasoline units — Switch off the gasoline engine and circumstances may any remaining coating material dry and harden in let it cool down.
Cleaning the unit (shutting down) Cleaning Airless spray gun – Rinse Airless spray gun with an appropriate cleaning agent. – Clean tip thoroughly with appropriate cleaning agent so that no coating material residue remains. – Thoroughly clean the outside of the Airless spray gun.

Remedy in case of faults Material feed pump Type of malfunction Possible cause Measures for eliminating the malfunction A. A sufficient amount of coating Inlet valve is leaky due to impurities or Clean and check the inlet valve housing. Insert ball and fill material is ejected only with an wear.
Oil and oil filter change ot the hydraulic oil The risk of damage rises with the age of the high- pump pressure hose. Wagner recommends replacing high- pressure hoses after 6 years. Carry out oil and oil filter change once every 12 months.
Appendix Appendix 11.1 Selection of tip To achieve faultless and rational working, the selection of the tip is of the greatest importance. In many cases the correct tip can only be determined by means of a spraying test. Some rules for this: The spray jet must be even. If streaks appear in the spray jet the spraying pressure is either too low or the viscosity of the coating material to high. Remedy: Increase pressure or dilute coating material. Each pump conveys a certain quantity in proportion to the size of the tip: The following principle is valid: large tip = low pressure...
