Maintenance and Service
NOTICE
Protect the internal drive parts of this sprayer
from water. Openings in shroud allow cooling of
mechanical parts and electronics inside. If water
gets into these openings, the sprayer could malfunc-
tion or be permanently damaged.

Caring for Sprayer

Keep sprayer and all accessories clean and in good
working order.
To avoid overheating motor, keep vent holes in shroud
clear for air flow. Do not cover sprayer while spraying.

Paint Hoses

Check hose for damage every time you spray. Do not
attempt to repair hose if hose jacket or fittings are dam-
aged. Do not use hoses shorter than 7.5 m (25 ft).
Wrench tighten using two wrenches.

Tips

• Always clean tips with compatible solvent and brush
after spraying.
• Tips may require replacement after 57 liters (15 gal-
lons) or they may last through 227 liters (60 gallons)
depending on abrasiveness of paint.
• Do not spray with worn tip.

Pump Check Valves

• Storing in water, inadequate flushing or ingested
debris can cause either of the two check valves to
malfunction.
• If pump does not prime after 30 seconds, try to
loosen check balls by tapping the inlet valve with a
small wrench as the sprayer is stroking.
NOTICE
Excessive shock will fracture or cause damage to
pump.
NOTE: To verify inlet valve ball is sticking, unscrew
valves from pump and check them.
If sprayer continues to cycle (motor and pump run) after
you release gun trigger, pump valves may be obstructed
or worn. Valve repair kits are available from Graco/Mag-
num authorized service dealers.
