Pressure Relief Procedure
The system pressure must be manually relieved to prevent 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, follow 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.
1Lock gun trigger safety.
2Turn engine ON/OFF switch to OFF.
3Move pump valve to OFF (down) and turn pressure control knob fully counter clockwise.
4Unlock trigger safety. Hold metal part of gun firmly to side of grounded metal pail, and trigger gun to relieve pressure.
5Lock gun trigger safety.
6Open pressure drain valve. Leave valve open until ready to spray again.
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.
AFTER THE FIRST 20 HOURS OF OPERATION:
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.
AFTER EACH 100 HOURS OF OPERATION:
Change engine oil. Reference Honda Engines Owner's Manual for correct oil viscosity.
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.
