Honda Engines Owners Manuals

You must know the model number for your Honda engine in order to get the owner's manual. To find the model number, look for a model number sticker on the engine. All Honda engines model numbers start with the letter "G," such as "G100", "GX610", or "GXV160." For some engines, you will also need to locate the serial number, which is stamped into the side of the engine.

Click on the model number below to find the correct owner's manual for your particular engine. Honda is continually updating its online library; so if the owner's manual that you are looking for is not currently shown, check back soon.

In order to view and print Honda Owner’s Manuals, your computer must have Adobe Acrobat Reader software (4.0 or later version) installed. If you don't have this software, it is available free here.

Initial Setup and Operation of Your New Pressure Washer

Inspection for freight damage
When you receive your commercial pressure washer be sure you check for concealed freight damage. Any damage should be noted with the delivering carrier. If you have any questions related to freight call our 866 toll free number immediately.

Inspection of oil levels
Check all oil levels in the pump or engine if applicable. Failure to check all levels will result in pressure washer damage. Most pumps are shipped with oil from factory and the crankcases are sealed; you may have to remove a shipping plug and install a dipstick in the pump. Oil type is stated on the pump breakdown and in the engine book.

Water Supply
Your water supply must provide water to the equipment that exceeds the Gallon Per Minute {GPM} rate of your machine. You can check your GPM by using a 5 Gallon bucket and a timer. If your machine is 5 GPM or less and the bucket fills in less than a minute you have adequate supply. Some systems are effected by things like washing machines, livestock watering systems and flushing of toilets. Be sure the supply is still adequate when these operations are taking place. The water temperature cannot exceed 145 Degrees Fahrenheit on the standard models and 180 degrees Fahrenheit on the high temperature models and the pressure should not exceed 60 PSI. Failure to secure adequate water supply to your commercial pressure washer will result in pump damage. DO NOT RUN PUMP DRY.

Water Quality
Your water should not contain particles larger than 80 microns. Although there are small filters installed on power washers that filter the water, they could only filter poor quality water for a short period of time before they clog. This would result in damage to the machine. Therefore you should insure no sand or scale particles are present in the water supply.

Supply Hose
Hook a garden hose from the hydrant to the machine, when doing this be sure to check the inlet water filter or screen. This hose should be at least 5/8” diameter and a length at least 15 feet. This 15’ length helps isolate the water supply from pulsations from the pump. Many states require a Vacuum Break or back flow prevention be installed at the hydrant, before the garden hose, to insure the water source cannot be contaminated. Be sure to check local and state regulations upon installation.

Purge Air
Turn on the water supply and open the trigger gun, this will purge all the air from the system. Look for water leaks and stop any leak found. Leaks can cause erratic pump behavior.

Electrical Supply
A circuit dedicated only to the pressure washer is recommended. This circuit should be installed by a licensed electrician and checked to supply adequate voltage Under Load. Sometimes the distance from the panel is to long, the wire size is to small or the voltage is initially to low, this will cause the GFCI or Thermal to trip. If the GFCI trips or the thermal overload on the motor trips consult factory. Plug your cord into the receptacle. DO NOT USE EXTENSION CORD!

Pump
Prior to turning on the power switches or your engine check the oil level in the pump.

Turn on Power
Turn on the power switch. Pull trigger gun and check for adequate pressure.

During Operation
The pressure was set at the factory during the testing procedure, no adjustments to the machine should be required for operation. During operation do not leave the machine running for more than 2 minutes without the trigger gun being pulled. Although your machine has a by-pass valve on it and may have a thermal relief system, this can cause extensive pump damage. If machine will not be discharging water for more than 2 minutes, shut the machine off.

 

Tip Styles

Interchangeable Tips
Your machine is supplied with either interchangeable tips or a multi-reg. Your machine is supplied with interchangeable spray tips. The black tip lowers your pressure and draws chemical. The other tips are for high pressure rinse at different spray angles. Red is 0 degree, yellow is 15 degree, green is 25 degree and white is 40 degree. The yellow tip is used for most standard applications. Be sure the quick coupler is fully engaged before pulling the trigger gun. Failure to do may result in the tip becoming a projectile and may be lost or damage to property or persons may occur. See the table to choose the right nozzle for your machine.

Chemical injector use with interchangeable tips
Your pressure washer is supplied with a downstream chemical injector. The 1/4” clear vinyl tube is to be inserted into the desired chemical to apply. Be sure to use the black, low pressure nozzle to inject chemical. The chemical injector will only open up and allow chemical into the line when this tip is used. This tip enables the pressure to drop to approximately 250 PSI to draw chemical. The injector can be shut on and off or the rate of injection can also be set by turning the knob that the clear vinyl tube attaches
to. See calibration below. Be sure to flush injection system with clear water after use.

Multi-Reg (Adjustable) Tip
If your machine is supplied with an adjustable tip, the spray pattern can be changed by rotating the outer shell of the nozzle. the nozzle also will move forward and backward. The nozzle must be pulled back toward the gun for high pressure rinse. When the nozzle is moved forward you will have low pressure and the soap injector will start to draw chemical.

Chemical injector use with multi-reg tip
Move the outer shell of your tip forward(away from the gun). This will lower your pressure and allow the injector to start to draw chemical. Chemical will only be drawn in the low pressure setting. Pull nozzle back for high pressure rinse.

Calibration
If an accurate injection rate is desired, use this formula: (GPM x 128) ÷ (ounces drawn in 1 minute) = x:1
IE: If a 2.0 GPM machine draws 8 ounces of chemical in 1 minute: (2 x 128) / 8 = 32:1

Hoses and couplers
Factory supplied hoses are sized in length and diameter for best operational performance and sized within the pressure capabilities. Additional hose added to the machine may change the performance of the machine. Consult factory if you have any questions. When replacing or disconnecting the quick couplers be sure the machine is shut off and relieve the pressure from all hoses.

 

Shut Down Procedure

Storage

  1. Turn off the power switch on the commercial pressure washer
  2. Relieve pressure on line by pulling trigger gun
  3. Shut off water supply and disconnect garden hose
  4. Be sure to check for water leaks or oil leaks that should be repaired before the next operation
  5. If you are going to store the machine for extended period of times in cold climates be sure to antifreeze the equipment. A 50% anti-freeze solution may be drawn in through the inlet of the pump using a short remnant of garden hose. This fluid should be run through the pump when the fluid is discharged from the pump discharge your machine is winterized. Do not allow machine to freeze.

Pump
The pump oil should be changed after the first 50 hours of operation, then every year for average service or more frequently for extensive use or hostile environments {dusty or high moisture}

Filters
Water filters, hoses and fittings should be checked prior to every operation for cleanliness, leaks and repair needs. Repair or replace as needed.
