Daily Maintenance

NOTICE

Do not open/remove gear cover. The gear side is not intended to be serviced. Opening the gear cover may alter the factory set bearing pre-load and may reduce the product life.

Preventative Maintenance

Schedule

NOTE: For overnight shutdown, stop pump at bottom of its stroke to prevent fluid from drying on exposed displacement rod and damaging throat packings. Perform

Pressure Relief Procedure, page 10.

1.

Perform Flush procedure, page 11.

2.

Relieve pressure. See Pressure Relief Procedure, page 10.

3.

Check packing nut (D) See F IG . 1, page 5. Adjust packings and replace TSL as necessary. Torque to

25 ft-lb (34 N•m).

4.

Check hoses, tubes, and couplings. Tighten all fluid connections before each use.

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.

Change the Oil

NOTE: Change the oil after a break-in period of 200,000 to 300,000 cycles. After the break-in period, change the oil once per year.

1.

Place a minimum 2 quart (1.9 liter) container under the oil drain port. Remove the oil drain plug. Allow all oil to drain from the driver.

2.

Reinstall the oil drain plug. Torque to 25-30 ft-lb

(34-40 N•m).

3.

Open the fill cap (P) and add Graco Part 16W645

ISO 220 silicone-free synthetic gear oil. Check the oil level in the sight glass (K). Fill until the oil level is near the halfway point of the sight glass. The oil capacity is approximately 1.0 - 1.2 quarts (0.9 - 1.1

liters). Do not overfill.

4.

Reinstall the fill cap. See F IG . 7, page 8.

Check Oil Level

See F IG . 7, page 8. Check the oil level in 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 fill cap (P) and add Graco Part No. 16W645 ISO

220 silicone-free synthetic gear oil.

The oil capacity is approximately 1.0 - 1.2 quarts

(0.9 - 1.1 liters). Do not overfill.

NOTE: Two 1 quart (0.95 liters) bottles of oil are supplied with equipment.

NOTICE

Only use oil 16W645. Any other oil may reduce the life of the gears.

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.

Perform Pressure Relief Procedure (page 10), but

leave rust inhibitor in pump to protect parts from corrosion.

Maintenance

Flushing

• Flush before changing fluids, before fluid can dry 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 the following figure.

Keep the cart clean by wiping up spills daily, using a compatible solvent.
