Check the identification plate (ID) on your lower for the 6-digit part number of your
lower. Use the following matrix to define the construction of your lower, based on the
six digits. For example, Lower Part Number L180C1 represents the lower (L), output
volume (180), carbon steel construction (C), and no filter with Xtreme Seal
stack (1).
To order replacement parts, see Parts, starting on page 16.

to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable
fumes are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• 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 gun, 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 gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
•
Follow Pressure Relief Procedure in manual 311164, when you stop spraying and before cleaning, checking, or servicing equipment.
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 Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data 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.

Repair kits are available to replace the throat (3)
and piston (4) packings, and to replace the o-rings
and cylinder seals. For best results, use all new
parts in the kit. Kit parts are marked with an asterisk, for example (25*). These kits can also be used
to convert the lower to different packing materials.
See the Packing Kits sections.
3. For lowers with built-in filters, loosen and remove
both top filter cap (20) and bottom filter cap (26).

NOTICE
To reduce the possibility of costly damage to displacement rod (1) and lower cylinder (11), first place lower
cylinder on a soft block of wood. Always use a rubber
mallet or an arbor press to drive the displacement rod
out of the lower cylinder. Never use a hammer to drive
the rod out. Damage to the rod end will shorten pump
life.
