Grounding
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.
Grounding a metail pail:
Connect a ground wire to the
pail by clamping one end to pail and other end to a true
earth ground such as water pipe.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of spray gun firmly
to side of a grounded metal pail. Then trigger gun.
Pressure Relief Procedure
1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pump switch to OFF and turn pressure control
knob fully counterclockwise.
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 hose for wear and damage.
DAILY:
Check gun safety for proper operation.
DAILY:
Check pressure drain valve for proper opera-
tion.
DAILY:
Check and fill the gas tank.
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 air filter cover and clean element.
Replace element, if necessary. If operating in an unusu-
ally dusty environment: check filter daily and replace, if
necessary.
Repack connecting rod (22) top needle bearing after
every pump change.
Replacement elements can be purchased from your
local HONDA dealer.
WEEKLY:
Check level of TSL in displacement pump
packing nut. Fill nut, if necessary. Keep TSL in nut to
help prevent fluid buildup on piston rod and premature
wear of packings.
AFTER EACH 100 HOURS OF OPERATION:
Change
engine oil. Reference Honda Engines Owner’s Manual
for correct oil viscosity.
SPARK PLUG:
Use only BPR6ES (NGK) or W20EPRU
(NIPPONDENSO) plug. Gap plug to 0.028 to 0.031 in.
(0.7 to 0.8 mm). Use spark plug wrench when installing
and removing plug.
INJECTION HAZARD
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,
follow the
Pressure Relief Procedure
whenever you:
•
are instructedtorelieve thepressure,
•
stop spraying,
•
check or service any of the system equipment,
•
or install or clean the spray tip.
NOTICE
For detailed engine maintenance and specifications,
refer to separate Honda Engines Owner Manual,
supplied.
