Maintenance

1.Always stop the pump at the bottom of its stroke when you take a break and at the end of the day. This helps keep fluid from drying on the rod and damaging the packings.

2.Keep the displacement pump packing nut/wet cup 1/3 full of TSL at all times. The TSL helps protect the packings and rod.

3.Check the tightness of the packing nut daily. It should be tight enough to stop leakage but no tighter.

CAUTION

Proper engine and hydraulic oil level is important to prevent costly damage to the sprayer. Check it as often as recommended in Steps 4 and 5., below.

4.Check the hydraulic oil level weekly. The oil must be up to the top mark on the dipstick. Use only Graco Hydraulic Oil.

5.Check the engine oil level at least weekly. The oil must be up to the FULL mark on the dipstick. The engine should not use more than one ounce of oil per hour of operation. Consult the engine manual, supplied, for additional recommended maintenance.

6.Inspect the return line filter frequently for clog- ging. Replace it after every 500 hours of operation or every 6 months, whichever comes first. A clogged or worn out filter reduces filter capability and will damage the hydraulic pump.

7.Check the battery water level periodically and refill as necessary.

8.Change the hydraulic oil after every 2000 hours of operation or every 12 months, whichever comes first. For continuous operation in tempera- tures above 85_F (30_C), change the oil after every 1000 hours or 6 months of use. See Step 9. for the procedure.

CAUTION

Cleanliness is essential when servicing the hydraulic system. Use special care to avoid getting dust or dirt into the hydraulic system to prevent damage to the hydraulic components.

9.To change the hydraulic oil:

a.Follow the Pressure Relief Procedure Warning on page 10.

b.Place a waste container under the drain plug of the hydraulic reservoir. See Fig 7. Unscrew the plug and drain the reservoir. Reinstall the plug before proceeding.

c.Remove the nuts and reservoir cover.

d.Remove the return line filter and install a new filter assembly.

e.Inspect the inlet filter and replace it if needed.

f.Install the reservoir cover and nuts. Then pour in five gallons (19 liters) of Graco Hydraulic Oil through the intake filter. See Fig 7. Install the fill cap.
