General Repair and Service Notes

1. Before repairing any part of the sprayer, read the instructions
carefully, including all warnings.
Never pull on a wire to disconnect it. Pulling on a
wire could loosen the connector from the wire.
Attention
2. Test your repair before regular operation of the sprayer to be
sure that the problem is corrected. If the sprayer does not
operate properly, review the repair procedure to determine if
everything was done correctly. Refer to the Troubleshooting
section to help identify other possible problems.
3. Make certain that the service area is well ventilated in case
solvents are used during cleaning. Always wear protective
eyewear while servicing. Additional protective equipment
may be required depending on the type of cleaning solvent.
Always contact the supplier of solvents for recommendations.
4. If you have any further questions concerning your Wagner
airless sprayer, contact a Wagner Authorized Service Center.

Routine Engine Maintenance

• After the first 20 hours of operation, drain the oil and refill
with clean oil. Check the engine oil level and fill as necessary.
Weekly
• Remove the cover of the air filter and clean the element.
Replace the element if necessary. If operating in an unusually
dusty environment, check the filter daily and replace if
necessary. (Replacement elements can be purchased from
your local Wagner dealer.)
• After each 50 hours of operation: Change the engine oil.
Spark Plug

• Make sure to use a spark plug wrench when installing and
removing the plug.

High-pressure hose

Inspect the high-pressure hose visually for any notches or bulges, in
particular at the transition in the fittings. It must be possible to turn
the union nuts freely.
The risk of damage rises with the age of the high-
i
pressure hose. Wagner recommends replacing high-
pressure hoses after 6 years.
