WARNING
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be aware that
flammable fumes can ignite or explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground all equipment in the work area.
• Use only grounded hoses.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you
identify and correct the problem.
• Keep a working fire extinguisher in the work area.
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 end of 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 spraying and before cleaning, checking, or
servicing equipment.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component.
See Techni cal Dat a in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technica l Da ta in all equipment
manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material,
request MSDS forms from distributor or retailer.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s
replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the
equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing
loss. This equipment includes but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing protection

Pressure Relief Instructions
Follow this pressure relief procedure whenever you are
instructed to relieve pressure or need to check or service equipment.
SVK Models
Starting Lubricator
To relieve pressure, loosen vent screw DSL Models: (a)
in F
IG. 1; SVK Models: (e) in FIG. 2, allowing pressure to
vent.

To start lubricator for the first time, or to prime lubricator
if it stops feeding due to lack of oil in the reservoir:
1. Verify reservoir is filled with oil.
2. Loosen or remove small hexagonal screw (e) in
FIG. 1
1. Verify reservoir is filled with oil.
2. Remove vent screw (a) on sight dome.
3. Fill dome to upper line with oil.
4. Replace and tighten vent screw (a) (hand tight only
is recommended).
5. Remove hex coupling nut on outlet fitting.
6. Prime by manually pumping spindle (b) in front of
sight dome until air bubbles are purged.
7. Retighten outlet nut.

3. Prime by manually pumping spindle (b) unit until
clear oil is delivered.
NOTE: For quicker results adjustment should be made
for full amount.
Adjusting Rate of Flow
DSL and SVK Models
1. Loosen lock nut (c) on adjustment gland.
2. To increase flow, turn adjustment gland (d) counter-clockwise, to decrease flow turn adjustment
gland clockwise.
3. Tighten lock nut (c).
NOTE: Pump unit manually each week to purge air
which might be trapped in oil supply.
