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

NOTICE

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

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 18-23 ft-lb

(25-30 N•m).

3.

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

ISO 220 silicone-free synthetic EP gear oil. Check

the oil level in the sight glass (K). (See F IG . 8.) 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.

Maintenance

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.

Cart Maintenance

Periodically lubricate the axle between points A and B with lightweight oil. See the following figure.

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.
