Shutdown

Shutdown
NOTICE
Never leave water or water-based fluid in pump over
night. If water-base fluid has been used, flush with
water first, then with a rust inhibitor (such as mineral
spirits). Relieve pressure, but leave rust inhibitor in
pump to protect parts from corrosion.
To shutdown:
1. Follow the Prime/Flush on page 11.
2. Follow the Pressure Relief Procedure on page 10.

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
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive 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
200,000–300,000 cycles. After the break-in period,
change the oil once a year.

other oil may not lubricate properly and can cause
damage to the drive train.
4. Reinstall the oil fill cap (P).

Daily Maintenance

NOTE: For overnight shutdown, stop pump at bottom of
its stroke to prevent fluid from drying on exposed
displacement rod and damaging throat packings. Follow
the Pressure Relief Procedure on page 10.
1. Follow the Prime/Flush on page 11.
2. Follow the Pressure Relief Procedure on page 10.
3. Check packing nut (D). Adjust packings and replace
TSL as necessary. See lower pump manual 311762
for packing nut toque.
4. Check hoses, tubes, and couplings. Tighten all fluid
connections before each use.
