Instructions
Always use all new parts included in your kit and dis-
pose of replaced parts according to all state and local
regulations for disposal of discarded components.
Inspect all parts when disassembling the pump. Replace
any and all worn and damaged parts.
Pressure Relief Procedure
The equipment stays pressurized until pressure is manually
relieved. To reduce the risk of serious injury from pressur-
ized fluid, fluid from the valve, or splashing fluid, follow the
procedure whenever you:
•
are instructed to relieve pressure
•
stop dispensing
•
check, clean, or service any system equipment
•
install or clean dispensing devices.
1. Close the pump's bleed-type master air valve.
2. Close the pump air regulator and disconnect the air
supply hose.
3. Open the dispensing valve and dispense fluid into a
waste bucket/container until pressure is fully
relieved.
If you suspect that the dispensing valve is clogged, or
that pressure has not been fully relieved after following
the steps above, very slowly loosen the dispensing
valve coupler or hose end coupling to relieve pressure
gradually, then loosen completely.
Disassembly
The following disassembly instructions describe the pro-
cedure for completely disassembling the LD oil pump.
Depending on the repair/maintenance procedure you
are performing on the pump, it may not be necessary to
entirely disassemble the pump or perform all steps in
this procedure.
The reference numbers used in the following instruc-
tions correspond to the reference numbers used in the
LD Series Oil and Grease Pump instruction manual.
