Check Oil Level

Check the oil level in sight glass (K). (See F IG . 9.) The oil level should be near the halfway point of the sight glass when the sprayer is not running. If oil is low, open vented oil cap (P) and add Graco Part No. 16W645 ISO

220 silicone-free synthetic EP gear oil. See F IG . 9.

The oil capacity is approximately 1.0 - 1.2 quarts (0.9 -

1.1 liters).

NOTICE

Only use oil with Graco part number 16W645. Any other oil may not lubricate properly and can cause damage to the drive train.

The operating conditions of your particular system determine how often maintenance is required. Establish a preventative maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.
