Operation
Startup
Before attempting to operate any system, check the
following:
• Ensure the reservoir is securely fastened to the
pump and that the fill cap or grease-fill fitting is eas-
ily reached.
• Check that the pump is securely fastened in place.
• Check that gear reducer has been filled with proper
lubricant.
• Check all electrical connections to any controllers,
level switches or pressure switches used on the sys-
tem.
• Check that all accessories plumbed into the output
manifold block assembly are secure.
• Make sure all hose or tubing connections are tight.
• Check that the reservoir is filled with lubricant. See
Filling the Reservoir, page 9.
• Check that all filling and bleeding steps have been
completed.
• Check the output of the lubricant pump. Adjust the
output as described in the Clutch Drive - Calculating
Pump Output, page 12.
• If the pump is equipped with a clutch drive, verify it
is
properly adjusted as described in the Adjusting
the Clutch Drive section, page 11.
The unit is now ready to run. The pump is cycled by an
external source, such as a timer, counter, control pack-
age, or customer-supplied drive. Once this external
source is engaged, the unit will cycle as programmed.
While the system is operating, periodically check
the following components:
• Check that the pump is cycling according to sched-
ule.
• Visually check the unit for leaks and loose fittings.
Make sure that hoses do not become kinked and
are not rubbing on anything.
• If the reservoir is not equipped with a low-level
switch, visually check the lubricant level and refill
before all lubricant is used.
NOTE: If the reservoir is allowed to run dry, excess
air will be introduced into the system, requiring that
the system be bled.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Verify pump is stopped and disconnected from
power source.
2. Using a wrench, slowly loosen the outlet fitting (a,
F
IG
. 9) connected to the pump block manifold
assembly until the fitting is loose and no more lubri-
cant or air is leaking from the fitting.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop dispensing and before clean-
ing, checking, or servicing the equipment.
