Maintenance

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, follow the Pressure Relief Procedure on page 10.

DAILY: Check the engine oil level and fill as neces- sary.

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 the oil and refill with clean oil.

WEEKLY: Remove the cover of the air filter and clean the element. Replace the element, if necessary. If operating in an unusually dusty environment, check the filter daily and replace it, if necessary.

Replacement elements can be purchased from your local HONDA dealer.

WEEKLY: Check the level of the TSL in the displace- ment pump packing nut. Fill the nut, if necessary. Keep TSL in the nut to help prevent fluid buildup on the piston rod and premature wear of the packings.

AFTER EACH 100 HOURS OF OPERATION: Change the oil.

MONTHLY: Oil connecting rod.

SPARK PLUG: Use only an (NGK) BPR6ES or W20 EPR-U (NIPPON DENSO) plug. Gap the plug to 0.028 to 0.031 inch (0.7 to 0.8 mm). Use a spark plug wrench when installing and removing the plug.

CAUTION

For detailed engine maintenance and specifications, refer to the separate engine manual, supplied.

WARNING

INJECTION HAZARD

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:

Dare instructed to relieve the pressure,

Dstop spraying,

Dcheck or service any of the system equipment,

Dor install or clean the spray tip.

Pressure Relief Procedure

1.Lock the gun trigger safety.

2.Turn the engine switch to OFF.

3.Move the pressure control switch to OFF.

4.Unlock the trigger safety. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve the pressure.

See Fig. 4, A.

5.Lock the gun trigger safety.

6.Open the pressure drain valve. Leave the valve open until you are ready to spray again.

7.Disconnect the spark plug cable.

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 the tip guard retaining nut or hose end coupling to relieve the pressure gradually, then loosen com- pletely. Now clear the tip or hose.
