Warnings
SKIN INJECTION HAZARD
High-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This may look like just a
cut, but it is a serious injury that can result in amputation. Get
immediate surgical treatment.
• Do not point dispense valve at anyone or at any part of
the body.
• Do not put your hand over the dispense nozzle.
• Do not stop or deflect leaks with your hand, body, glove,
or rag.
• Follow Pressure Relief Procedure in this manual, when
you stop dispensing and before cleaning, checking, or
servicing equipment.
Pressure Relief Procedure
The equipment may be pressurized or may become
pressurized by an automatic lubrication cycle initiated by
a lubrication controller such as a timer. To avoid serious
injury including the kind of injuries described in the Skin
Injection Hazard warning:
1. Disconnect power to the timer.
2. If connected to an air supply, disconnect air supply
to pump module to ensure the system is depressurized.
Adjustment Instructions
Reference numbers refer to parts (FIG. 1 and page 3).
1. Loosen lock nut (7).
2. Hand tighten the Adjuster Nut (8) then loosen,
approximately 1/2 turn to achieve the minimum dis-
pensed output volume (.001 in.
NOTE: Any output setting below 1/2 turn should be
monitored to verify actual output volume.
3. Retracting the Adjuster Nut (8) five full turns from
the hand-tight position permits a maximum dis-
pensed output volume (.008 in.
preset position.
NOTE:
• Each full turn out represents an addition of
approximately 0.0014 in.
• The amount of dispensed volume can vary
depending on external conditions such as lubricant temperature and back pressure from the
downstream connection.
4. When the injector has been adjusted for the proper
lubricant output, wrench tighten the stroke adjustment lock nut (7).
NOTICE
To prevent component failure, the adjustment nut
(8) must not be extended beyond the fully retracted
position of the piston (6). See F
