Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.

If after following these steps you suspect the spray tip or
hose is still clogged or that pressure has not been fully
relieved, very slowly loosen tip guard retaining nut or
hose end coupling to relieve pressure gradually. Then
loosen completely.
Maintenance
NOTE: For detailed engine maintenance and specifica-
tions, see separate Honda owner's engine manual (sup-
plied).
DAILY: Check hydraulic oil level and fill as necessary.
DAILY: Check gas engine 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 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.
WEEKLY/DAILY: Remove any debris or media from
hydraulic rod.
AFTER EACH 100 HOURS OF OPERATION: Change
engine oil (see Honda engine owner's manual for correct
oil viscosity).
SEMI-ANNUALLY:
Check belt wear, replace if necessary.
YEARLY OR 2000 HOURS: Replace belt.
Replace hydraulic oil and filter with Graco hydraulic oil
169236 (5 gallon/20 liter) or 207428 (1 gallon/3.8 liter)
and filter 116909.
SPARK PLUG: Use only BPRGES or W20EPR-U
(NIPPONDENSO) plugs. Gap plug to 0.028 - 0.031 in
(0.7 - 0.8 mm). Use spark plug wrench when installing or
removing plug.
