Hitachi 1800 Manual Do Utilizador

The equipment 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.

Pump: Use the ground screw (GS) and lockwasher on 
the motor to attach a 244524 ground wire (Y). Tighten 
the screw securely. Connect the other end of the ground 
wire to a true earth ground.

Air and fluid hoses: use only electrically conductive 
hoses. 

Air compressor or hydraulic power supply: follow 
manufacturer’s recommendations.

Spray gun: ground through connection to a properly 
grounded fluid hose and pump.

Fluid supply container: follow local code.

Object being sprayed: follow local code. 

Solvent pails used when flushing: follow local code. 
Use only conductive metal pails, placed on a grounded 
surface. Do not place the pail on a nonconductive sur-
face, such as paper or cardboard, which interrupts 
grounding continuity.

To maintain grounding continuity when flushing or 
relieving pressure: hold metal part of the spray gun 
firmly to the side of a grounded metal pail, then trigger 
the gun.

The equipment was tested with lightweight oil, which is 
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a 
compatible solvent before using the equipment. See 
Flushing, page 14.

See Dimensions, page 22 and Mounting Hole Lay-
outs, page 23.

. 2. Be sure all hoses are properly 

sized and pressure-rated for your system. Use only 
electrically conductive hoses. Fluid hoses must have 
spring guards on both ends. Use a whip hose (P) and a 
swivel (R) between the main fluid hose (N) and the 
gun/valve (S) to allow freer gun/valve movement.
