Grounding

334567E 11

Grounding

This sprayer includes a ground wire with an appropriate ground contact. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician.

Power Requirements

• 110-120V units require 100-120 VAC,

50/60 Hz, 13A, 1 phase.

• 230V units require 230 VAC, 50/60 HZ,

8A, 1 phase.

Extension Cords

Use an extension cord with an undamaged ground contact. If an extension cord is necessary, use a 3-wire, 12 AWG (2.5 mm

) minimum. NOTE: Smaller gauge or longer extension cords may reduce sprayer performance.

Pails

Solvent and oil-based fluids: follow local

code. Use only conductive metal pails, placed on a grounded surface such as concrete. Do not place pail on a non-conductive surface such as paper or cardboard which interrupts

grounding continuity.

Always ground a metal pail: connect a ground wire to the pail. Clamp one end to the pail and the other end to a true earth ground such as a water pipe.

To maintain ground continuity when sprayer is flushed or pressure is relieved:

hold metal part of spray gun firmly to the side of a grounded metal pail then trigger the gun.

The equipment must be grounded to reduce the risk of static sparking and electric shock. An electric or static spark can cause fumes to ignite or explode. An improper ground can cause electric shock. A good ground provides an escape wire for the electric current.

Routine maintenance is important to ensure proper operation of your sprayer. Maintenance includes performing routine actions which keep your sprayer in operation and prevents trouble in the future.

Activity Interval

Inspect/clean sprayer filter, fluid inlet strainer, and gun filter.

Daily

or each time you spray

Inspect motor shield vents for blockage. Daily

or each time you spray Fill TSL by adding through TSL fill point. Daily or each time you spray Inspect motor brushes for wear. Brushes must be 1/2 in.

(13mm) minimum length. NOTE: Brushes do not wear at the same rate on both sides of motor. Check both brushes.

Every 1000 gallons (3785 liters)

Check sprayer stall.

With sprayer gun NOT triggered, sprayer motor should stall and not restart until gun is triggered again.

If sprayer starts again with gun NOT triggered, inspect pump for internal/external leaks and check prime valve for leaks.

Every 1000 gallons (3785 liters)

Throat packing adjustment

When pump packing begins to leak after extended use, tighten packing nut down until leakage stops or lessens. This allows approximately 100 gallons of additional operation before a repacking is required. Packing nut can be tightened without O-ring removal.

As necessary based on usage

If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.
