Check Oil level
Check the oil level in the sight glass (K). The oil level
should be near the halfway point of the sight glass when
the sprayer is not running. If oil is low, open the fill cap
(P) and add Graco Part No. 16W645 silicone-free ISO
220 synthetic EP gear oil.
The oil capacity is approximately 1.0–1.2 quarts (0.9–
1.1 liters). Do not overfill.
NOTE:
The driver gear box is shipped from the factory
pre-filled with oil. The temporary unvented cap (PX)
prevents oil leaks during shipment. This temporary cap
must be replaced with the supplied vented oil cap (P)
before use.
Corrosion Protection
Always flush the pump before fluid dries on the
displacement rod. Never leave water or water-based
fluid in the pump overnight. First, flush with water or a
compatible solvent, then with a rust inhibitor, such as
mineral spirits. Follow the
on page 10, but leave rust inhibitor in pump to protect
parts from corrosion.
Flushing
•
Flush before changing fluids, before fluid can cure in
the equipment, at the end of the day, before storing,
and before repairing equipment.
•
Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
•
Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Cart Maintenance
Periodically lubricate the axle between points A and B
with lightweight oil (see below).
Keep the cart clean by wiping up spills daily, using a
compatible solvent.
NOTICE
Only use oil with Graco part number 16W645. Any
other oil may reduce the life of the gears.
