Storage & Maintenance Instructions

SPECIFIC MAINTENANCE

MAINTENANCE - EVERY 3 MONTHS

ENGINE: The engine instructions that accompany your unit detail specific 

procedures for maintenance of the engine. Following the engine 

manufacturer’s recommendations will extend engine work life.

PUMP: Change the pump oil after the first 50 hours of operation. After 

initial change, every 3 months or 250 hour intervals are recommended. 

If oil appears dirty or milky, changes may be required in greater 

frequency. Use SAE20 or 30 non-detergent pump oil and fill only to 

the center of the oil sight glass. DO NOT overfill.

NOZZLE: Water flow through the spray nozzle will erode the orifice, 

making it larger, resulting in a pressure loss. Nozzles should be 

replaced whenever pressure is less than 85% of the maximum. The 

frequency of replacement will depend upon such variables as mineral 

content in the water and number of hours the nozzle is used.

CHANGE WATER PUMP OIL: Ensure unit is off. Change the pump 

oil after the first 50 hours of operation. After initial change, every 3 

months or 500 hour intervals are recommended. If oil appears dirty or 

milky, changes may be required in greater frequency. Use SAE20 or 

30 non-detergent pump oil and fill only to the center of the oil sight 

glass. DO NOT overfill.

REPLACE HIGH PRESSURE NOZZLE: Water flow through the spray 

nozzle will erode the orifice, making it larger, resulting in a pressure 

loss. Nozzles should be replaced whenever pressure is less than 85% 

of the maximum. The frequency of replacement will depend upon such 

variables as mineral content in the water and number of hours the 

nozzle is used.

BELT INSPECTION: Ensure unit is off and remove the beltguards. 

Inspect the v-belt for wear and tightness. If the v-belt needs to be 

replaced or tightened, follow the procedures listed below:

Replacement:

1. Loosen the four pump mounting bolts (A).

2. Loosen the two alignment nuts approximately one inch on the 

alignment bolts (B1 & B2).

3. Slide the pump toward the engine to loosen belts.

4. Remove and replace belt.

OPTIONS: HIGH PRESSURE DETERGENT

NOTICE

This feature is designed for use with mild detergents only. Since the

cleaning solution travels through the heat exchanger coil, DO NOT

use corrosives as they will cause extensive damage as well as pose a

considerable safety hazard.

HS-SERIES Operator's Manual

SHUTDOWN:

1.  Move the Burner switch to the 

OFF

 position.

2.  Squeeze the trigger and discharge the water for a period of three minutes 

to cool the heat exchanger and high pressure hose.  Insufficient cool-down 

periods for the high pressure hose will cause excessive wear and eventual 

rupture of the hose.

3.  Do not close the choke to stop the engine.  Backfire or engine damage may 

occur.

4.  Move the engine key switch to the 

OFF

 position.

5.  Turn off the water supply and trigger the gun momentarily to relieve trapped 

pressure.

Disconnect and drain the high pressure hose, gun, and lance.  Wipe the unit 

clean.  Store in a non-freezing environment.

OPTIONS:

HIGH PRESSURE DETERGENT: (Cleaning with Detergents) 

NOTE:  This feature is designed for use with mild detergents only.  Since the  

cleaning solution travels through various parts of the pressure washer, do 

not use corrosives as they will cause extensive damage as well as pose a 

considerable safety hazard.

1.  Refer to "Risk of Bodily Injury / Detergents" pg. 8-9.  Be certain to wear 

protective safety attire as stated on pg. 12. 

2.  Prepare detergent solution according to label directions.  (Never pump acids, 

alkalines, abrasive fluids or solvents through the unit. Due to the unknown 

and often corrosive characteristics of many detergents commonly used 

in the pressure washer cleaning industry, it is recommended to use only  

mild detergents with this unit.)

3.  Fully immerse the strainer end of the clear vinyl detergent hose into the 

detergent solution.

4.  To apply solution;  unlock the trigger gun and squeeze the trigger.  In a few 

moments a  detergent/water mixture will exit the nozzle.  Start spraying 

the lower portion of the surface being cleaned and move up, using long 

overlapping strokes.  Applying from the bottom up helps avoid streaking.  

Allow to soak briefly.  Avoid working on hot surfaces or in direct sunlight to 

minimize the chances of the detergent drying, which may result in damaging 

surfaces.  Be certain to apply cleaning solution to a small section at a time.

5.  To rinse;  lock the trigger gun in the "OFF" position. Turn the detergent 

metering valve to the "OFF" position. Unlock the trigger gun and spray.  It 

will take about 30 seconds to purge all detergent from the line.  For best 

rinsing results, start at the top and work down.

6.  Siphon a gallon of water through the detergent injection system after each 

use.  This prevents the possibility of corrosion or detergent residue causing 

mechanical problems during the next use.
