Maintenance and Service
CAUTION
Protect the internal drive parts of this sprayer from water.
Openings in the shroud allow for air cooling of the mechanical
parts and electronics inside. If water gets into these openings,
the sprayer could malfunction or be permanently damaged.
Caring for Sprayer
Keep the sprayer and all accessories clean and in good
working order. To avoid overheating of motor, keep vent
holes in shroud clear for air flow. Do not cover the
sprayer while spraying.
InstaClean Fluid Filter
The InstaClean fluid filter (E) self cleans during pressure
relief. Some embedded particles may require manual
cleaning. Remove pump fluid outlet fitting (D) to remove
and check InstaClean filter. Replace if damaged.

Paint 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).
Tips
Always clean tips with compatible solvent and a brush
after spraying.
Tips may require replacement after spraying 15 gallons
(57 liters), or they may last through 60 gallons (227
liters), depending on the abrasiveness of the paint. Do
not spray with a worn tip.
Pump Check Valves
Inadequate flushing of paint can
cause the inlet valve check balls to
stick to the seats. If the pump does not prime after 30
seconds of cycling, try tapping the inlet valve with a
small wrench to jar the balls loose.

NOTE: Excessive shock
will fracture or cause other
damage to the pump.
If the sprayer continues to cycle (motor and pump run)
after you release the gun trigger, the pump valves may
be obstructed or worn. If they are worn, the XR Valve
Kits (shown Kits Diagram) are available.
HINT: To be certain about whether the inlet valve ball is
sticking, you can unscrew the inlet valve from the pump
and check it. MAGNUM XR7 and XR9 sprayers allow for
inlet valve removal without removing the suction tube.
Pump Packings
When the pump packings wear, paint will begin to leak
down the outside of the pump. Replace the pump
packings at the first sign of leaking, or additional damage
could occur. Obtain an XR Pump Repair Kit (shown in
Kits Diagram), and install according to the instructions
on the kit packaging.

HINT: If leaking occurs in the middle of a paint job,
remove this clip, and tighten the existing packing module
all the way down. This will allow you to spray a few more
gallons before you have to install the XR Pump Repair Kit.
