Maintenance

Routine maintenance is important to ensure proper operation of your sprayer.

Airless Hoses

Check hose for damage every time you

spray. Do not attempt to repair hose if hose

jacket or fittings are damaged. Do not use

hoses shorter than 25 ft (7.6 m). Wrench

tighten, using two wrenches.

Spray Tips

•

Always clean tips with compatible

cleaning fluid and brush after spraying.

•

Tips may require replacement after 15

gallons (57 liters) or they may last

through 60 gallons (227 liters) depend-

ing on abrasiveness of paint.

Pump Repair

When pump packings wear, paint will begin

to leak down outside of pump.

•

Purchase a pump repair kit and install

according to instructions provided with

kit, before your next job.
