with grounding receptacle. Never use an outlet that is

not grounded or an adapter.

DDo not use the sprayer if the electrical cord has a damaged

ground prong. Only use an extension cord with an undamaged,

3–prong plug.

DRecommended extension cords for use with this sprayer:

D25 ft (7.6 m) 18 AWG

D50 ft (15.2 m) 16 AWG

D100 ft (30.5 m) 14 AWG

D150 ft. (45.7 m) 12 AWG

Smaller gauge or longer extension cords may reduce sprayer

performance.

Grounding and Electric Requirements

ti5572a

DGround sprayer gun through connection to a

properly grounded fluid hose and pump.

DGround fluid supply container. Follow local code.

The sprayer must be grounded. Grounding reduces the risk of static and

electric shock by providing an escape wire for the electrical current due to

static build up or in the event of a short circuit.

ti3001b

5309859

Grounding and Electric Requirements

DGround solvent pails used when flushing. Follow local code. Use

only conductive, metal pails, placed on a grounded surface such as

concrete. Do not place the pail on a non–conductive surface such

as paper or cardboard, which interrupts the grounding continuity.

ti5850a

ti5851a

DGround the metal pail by connecting a ground wire to the

pail by clamping one end to pail and the other end to

ground such as as water pipe.

DMaintain grounding continuity when flushing or

relieving pressure by holding metal part of spray gun

firmly to side of a grounded metal pail, then trigger gun.

Thermal Overload

DMotor has a thermal overload switch

to shut itself down if overheated.

To reduce risk of injury from motor staring

unexpectedly when it cools, always turn power

switch OFF if motor shuts down.
