Uniden GH 230 Manual Do Utilizador

The system pressure must be manually relieved to pre-
vent the system from starting or spraying accidentally. 
Fluid under high pressure can be injected through the 
skin and cause serious injury. To reduce the risk of an 
injury from injection, splashing fluid, or moving parts, fol-
low the Pressure Relief Procedure whenever you:
•

are instructed to relieve the pressure,

•

stop spraying,

•

check or service any of the system equipment,

•

or install or clean the spray tip.

1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pump valve to OFF (down) and turn pressure control 

knob fully counter clockwise.

4. Unlock trigger safety. Hold metal part of gun firmly to side of 

grounded metal pail, and trigger gun to relieve  pressure.

5. Lock gun trigger safety.
6. Open pressure drain valve. Leave valve open until ready to 

spray again. 

If you suspect that the spray tip or hose is completely 
clogged, or that pressure has not been fully relieved 
after following the steps above, VERY SLOWLY loosen 
tip guard retaining nut or hose end coupling to relieve 
pressure gradually, then loosen completely. Now clear 
tip or hose. 

DAILY: Check engine oil level and fill as necessary.

DAILY: Check hydraulic oil level and fill as necessary.

DAILY: Check hose for wear and damage.

DAILY: Check gun safety for proper operation.

DAILY: Check pressure drain valve for proper operation.

DAILY: Check and fill the gas tank.

DAILY: Check that displacement pump is tight.

DAILY: Check level of Throat Seal Liquid (TSL) in dis-
placement pump packing nut. Fill nut, if necessary. Keep 
TSL in nut to help prevent fluid buildup on piston rod and 
premature wear of packings and pump corrosion.

Drain engine oil and refill with clean oil. Reference 
Honda Engines Owner's Manual for correct oil viscosity.

WEEKLY: Remove engine air filter cover and clean ele-
ment. Replace element, if necessary. If operating in an 
unusually dusty environment: check filter daily and 
replace, if necessary.

Replacement elements can be purchased from your 
local HONDA dealer.

WEEKLY/DAILY: Remove any debris or media from 
hydraulic rod.

Change engine oil. Reference Honda Engines Owner's 
Manual for correct oil viscosity.

SEMI-ANNUALLY:
Check belt wear, page 10; replace if necessary.

Replace hydraulic oil and filter with Graco hydraulic oil 
169236 (5 gallon/20 liter) or 207428 (1 gallon/3.8 liter) 
and filter 116909.

Replace belt.

SPARK PLUG: Use only BPR6ES (NGK) or W20EPR-U
