Pressure Relief Procedure

2.
Open any bleed-type master air valves and fluid
drain valves in the system.
3.
Leave drain valves open until you have completed
repairs and are ready to pressurize system.
Service Instructions
1.
Check lubricator operation by observing the drip
tube. If the sight glass well pumps dry or no flow is
observed, check the following points until the cause
is determined and corrected.
•
Check the vent plug (A) for proper sealing. Any
knicks or cracks in the rubber plug will cause an
air leak into the sight glass (F
. 9).
•
Check shaft rotation. If the lubricator shaft is not
rotating, determine the cause and repair as nec-
essary.
•
Check oil level and viscosity. Be sure the reser-
voir is filled with oil, and if necessary heat the
reservoir to maintain viscosity at the correct
level for the desired flow.
•
Check pump priming. If necessary, prime the
pump in accordance with the operating instruc-
tions, page 6.
•
Check the feed adjustment (C, F
page 7) and adjust if the pumping rate is too
low.
•
Check the actuating linkage for proper opera-
tion. If defective, isolate the broken part and
repair or replace as required.
‘
The equipment stays pressurized until pressure is
relieved. To reduce the risk of serious injury from pres-
surized fluid, accidental spray from the dispenser, or
splashing fluid, follow this
Pressure Relief Procedure
whenever you:
•
Check, clean or service any system equipment.
•
Install or clean fluid nozzles.
NOTICE
•
All installation, maintenance, and repair work
must
be completed by qualified personnel.
•
If the correct pumping rate is maintained, no ser-
vice is required other than periodic replenish-
ment of the reservoir.
